National Geothermal Information Resource annual report, 1977  

DOE Green Energy (OSTI)

The National Geothermal Information Resource (GRID) of the Lawrence Berkeley Laboratory is chartered by the U.S. Department of Energy (DOE) to provide critically evaluated data and other information for the development and utilization of geothermal energy. Included are both site dependent and site independent information related to resource evaluation, electrical and direct utilization, environmental aspects, and the basic properties of aqueous electrolytes. The GRID project is involved in cooperative agreements for the interchange of information and data with other organizations. There are currently three U.S. data centers working to implement the collection and exchange of information on geothermal energy research and production: the DOE Technical Information Center (TIC), Oak Ridge, the GEOTHERM database of the U.S. Geological Survey in Menlo Park, and the GRID project. The data systems of TIC, GEOTHERM and GRID are coordinated for data collection and dissemination, with GRID serving as a clearinghouse having access to files from all geothermal databases including both numerical and bibliographic data. GRID interfaces with DOE/TIC for bibliographic information and with GEOTHERM for certain site-dependent numerical data. The program is organized into four principal areas: (1) basic geothermal energy data; (2) site-dependent data for both electrical and direct utilization; (3) environmental aspects, and (4) data handling development. The four sections of the report are organized in this way.

Geothermal Permeability Enhancement - Final Report  

Science Conference Proceedings (OSTI)

The overall objective is to apply known permeability enhancement techniques to reduce the number of wells needed and demonstrate the applicability of the techniques to other undeveloped or under-developed fields. The Enhanced Geothermal System (EGS) concept presented in this project enhances energy extraction from reduced permeability zones in the super-heated, vapor-dominated Aidlin Field of the The Geysers geothermal reservoir. Numerous geothermal reservoirs worldwide, over a wide temperature range, contain zones of low permeability which limit the development potential and the efficient recovery of heat from these reservoirs. Low permeability results from poorly connected fractures or the lack of fractures. The Enhanced Geothermal System concept presented here expands these technologies by applying and evaluating them in a systematic, integrated program.

Geothermal energy in California: Status report  

DOE Green Energy (OSTI)

The potential for electric energy from geothermal resources in California is currently estimated to be equivalent to the output from 14 to 21 large (1000 MW) central station power plants. In addition, since over 30 California cities are located near potential geothermal resources, the non-electric applications of geothermal heat (industrial, agriculture, space heating, etc.) could be enormous. Therefore, the full-scale utilization of geothermal resources would have a major impact upon the energy picture of the state. This report presents a summary of the existing status of geothermal energy development in the state of California as of the early part of 1976. The report provides data on the extent of the resource base of the state and the present outlook for its utilization. It identifies the existing local, state, and federal laws, rules and regulations governing geothermal energy development and the responsibilities of each of the regulatory agencies involved. It also presents the differences in the development requirements among several counties and between California and its neighboring states. Finally, it describes on-going and planned activities in resource assessment and exploration, utilization, and research and development. Separate abstracts are prepared for ERDA Energy Research Abstracts (ERA) for Sections II--VI and the three Appendixes.

Geothermal Heat Pump Benchmarking Report  

SciTech Connect

A benchmarking study was conducted on behalf of the Department of Energy to determine the critical factors in successful utility geothermal heat pump programs. A Successful program is one that has achieved significant market penetration. Successfully marketing geothermal heat pumps has presented some major challenges to the utility industry. However, select utilities have developed programs that generate significant GHP sales. This benchmarking study concludes that there are three factors critical to the success of utility GHP marking programs: (1) Top management marketing commitment; (2) An understanding of the fundamentals of marketing and business development; and (3) An aggressive competitive posture. To generate significant GHP sales, competitive market forces must by used. However, because utilities have functioned only in a regulated arena, these companies and their leaders are unschooled in competitive business practices. Therefore, a lack of experience coupled with an intrinsically non-competitive culture yields an industry environment that impedes the generation of significant GHP sales in many, but not all, utilities.

Geothermal Progress Monitor. Report No. 18  

DOE Green Energy (OSTI)

The near-term challenges of the US geothermal industry and its long-range potential are dominant themes in this issue of the US Department of Energy (DOE) Geothermal Progress Monitor which summarizes calendar-year 1996 events in geothermal development. Competition is seen as an antidote to current problems and a cornerstone of the future. Thus, industry's cost-cutting strategies needed to increase the competitiveness of geothermal energy in world markets are examined. For example, a major challenge facing the US industry today is that the sales contracts of independent producers have reached, or soon will, the critical stage when the prices utilities must pay them drop precipitously, aptly called the cliff. However, Thomas R. Mason, President and CEO of CalEnergy told the DOE 1996 Geothermal Program Review XIV audience that while some of his company's plants have ''gone over the cliff, the world is not coming to an end.'' With the imposition of severe cost-cutting strategies, he said, ''these plants remain profitable... although they have to be run with fewer people and less availability.'' The Technology Development section of the newsletter discusses enhancements to TOUGH2, the general purpose fluid and heat flow simulator and the analysis of drill cores from The Geysers, but the emphasis is on advanced drilling technologies.

Geothermal Progress Monitor, report No. 13  

DOE Green Energy (OSTI)

Geothermal Progress Monitor (GPM) Issue No. 13 documents that most related factors favor the growth and geographic expansion of the US geothermal industry and that the industry is being technologically prepared to meet those challenges into the next century. It is the function of GPM to identify trends in the use of this resource and to provide a historical record of its development pathway. The information assembled for this issue of GPM indicates that trends in the use of geothermal energy in this country and abroad continue to be very positive. Favorable sentiments as well as pertinent actions on the part of both government and industry are documented in almost every section. The FEDERAL BEAT points up that the National Energy Strategy (NES) developed at the highest levels of the US government recognizes the environmental and energy security advantages of renewable energy, including geothermal, and makes a commitment to substantial diversification'' of US sources of energy. With the announcement of the construction of several new plants and plant expansions, the INDUSTRY SCENE illustrates industry's continued expectation tha the use of geothermal energy will prove profitable to investors. In DEVELOPMENT STATUS, spokesmen for both an investor-owned utility and a major geothermal developer express strong support for geothermal power, particularly emphasizing its environmental advantages. DEVELOPMENT STATUS also reports that early successes have been achieved by joint DOE/industry R D at The Geysers which will have important impacts on the future management of this mature field. Also there is increasing interest in hot dry rock. Analyses conducted in support of the NES indicate that if all the postulated technology developments occur in this field, the price of energy derived from hot dry rock in the US could drop.

Downwell pump reliability: Geothermal experience update: Final report  

DOE Green Energy (OSTI)

Geothermal resources with temperatures between 250/sup 0/ and 360/sup 0/F (121/sup 0/C and 182/sup 0/C) are prime candidates for binary-cycle power generation, and constitute about 80% of the power-capable resources in the United States. The successful exploitation of these resources requires reliable high-capacity downwell brine production pumps, but earlier experience showed that high-capacity, high-temperature geothermal production pumps had many problems which resulted in a mean time-to-failure (MTTF) of less than 1000 h. However, steady progress has been made since 1981, and a large body of experience has been acquired by three geothermal binary plants. This survey of high-temperature geothermal downwell pump users and manufacturers updates a prior survey (AP-3572) completed in early 1983. This survey traces the development of lineshaft pump technology from the late 1970s to the present (mid-1987), detailing the advances in design, materials selection, and operating practices. Case histories of 72 lineshaft pumps installed at three geothermal binary plants since late 1981 are documented, including some detailed cause of failure reports. In the recent past, pump lives in excess of 7000 h have become common, but a high continuing rate of premature failures resulted in a mean time-to-failure (MTTF) of about 5000 h. Based on recent advances which appear likely to eliminate most premature failures, the estimated near-term MTTF will be on the order of 8000 h. The survey found almost no development of high-temperature geothermal electric submersible pumps (ESP's) or close-coupled downwell hydraulic turbopumps, and concluded that considerable development and demonstration will be needed before these technologies are able to compete with existing high-temperature geothermal lineshaft pump technology. 36 refs., 10 figs., 25 tabs.

Internal Technical Report, 1981 Annual Report, An Analysis of the Response of the Raft River Geothermal Site Monitor Wells  

Science Conference Proceedings (OSTI)

A groundwater monitoring program has been established on the Raft River Geothermal Site since 1978. The objective of this program is to document possible impacts that may be caused by geothermal production and injection on the shallow aquifers used for culinary and irrigation purposes. This annual progress report summarizes data from 12 monitor wells during 1981. These data are compared with long-term trends and are correlated with seasonal patterns, irrigation water use and geothermal production and testing. These results provide a basis for predicting long-term impacts of sustained geothermal production and testing. To date, there has been no effect on the water quality of the shallow aquifers.

Geothermal progress monitor: Report No. 17  

DOE Green Energy (OSTI)

DOE is particularly concerned with reducing the costs of geothermal power generation, especially with the abundant moderate to low-temperature resources in the US. This concern is reflected in DOE`s support of a number of energy conversion projects. Projects which focus on the costs and performance of binary cycle technology include a commercial demonstration of supersaturated turbine expansions, which earlier studies have indicated could increase the power produced per pound of fluid. Other binary cycle projects include evaluations of the performance of various working fluid mixtures and the development and testing of advanced heat rejection systems which are desperately needed in water-short geothermal areas. DOE is also investigating the applicability of flash steam technology to low-temperature resources, as an economic alternative to binary cycle systems. A low-cost, low-pressure steam turbine, selected for a grant, will be constructed to utilize fluid discharged from a flash steam plant in Nevada. Another project addresses the efficiency of high-temperature flash plants with a demonstration of the performance of the Biphase turbine which may increase the power output of such installations with no increase in fluid flow. Perhaps the most noteworthy feature of this issue of the GPM, the 17th since its inception in 1980, is the high degree of industry participation in federally-sponsored geothermal research and development. This report describes geothermal development activities.

Geothermal progress monitor. Report No. 16  

DOE Green Energy (OSTI)

This issue, the 16th since 1980, illustrates the potential of the liquid-dominated geothermal resource. Achievement of this potential by publicly held companies, who are required to publish financial statements, has involved the use of high-quality resources and the best available technologies or, in some instances, their own innovative modifications of existing technologies as well as a high degree of technical and management expertise. This issue also documents some effects of the new climate of utility deregulation and competition among independent power producers on the geothermal industry. The continuing importance attached to geothermal heat pumps as a preferred space conditioning technology by a number of disparate interests is illustrated by a number of articles. Magma Power Co. reported record gains in both 1993 revenues and earnings over 1992; California Energy has acquired Magma, creating the largest geothermal energy producer in the world. Owing to stagnation in USA, it was decided to focus on international markets. After the introduction, the issue has sections on: Federal beat, industry scene, financing, technology development, direct use technology, state and local, international, technology transfer, and directory.

US geothermal database and Oregon cascade thermal studies: (Final report)  

DOE Green Energy (OSTI)

This report describes two tasks of different nature. The first of these tasks was the preparation of a data base for heat flow and associated ancillary information for the United States. This data base is being used as the basis for preparation of the United States portion of a geothermal map of North America. The ''Geothermal Map of North America'' will be published as part of the Decade of North American Geology (DNAG) series of the Geological Society of America. The second of these tasks was to make a geothermal evaluation of holes drilled in the Cascade Range as part of a Department of Energy (DOE)/Industry co-sponsored deep drilling project. This second task involved field work, making temperature logs in the holes, and laboratory work, measuring thermal conductivity measurements on an extensive set of samples from these holes. The culmination of this task was an interpretation of heat flow values in terms of the regional thermal conditions; implications for geothermal systems in the Cascade Range; evaluation of the effect of groundwater flow on the depths that need to be drilled for successful measurements in the Cascade Range; and investigation of the nature of the surface groundwater effects on the temperature-depth curves. 40 refs., 7 figs., 7 tabs.

Geothermal pilot study final report: creating an international geothermal energy community  

DOE Green Energy (OSTI)

The Geothermal Pilot Study under the auspices of the Committee on the Challenges of Modern Society (CCMS) was established in 1973 to apply an action-oriented approach to international geothermal research and development, taking advantage of the established channels of governmental communication provided by the North Atlantic Treaty Organization (NATO). The Pilot Study was composed of five substudies. They included: computer-based information systems; direct application of geothermal energy; reservoir assessment; small geothermal power plants; and hot dry rock concepts. The most significant overall result of the CCMS Geothermal Pilot Study, which is now complete, is the establishment of an identifiable community of geothermal experts in a dozen or more countries active in development programs. Specific accomplishments include the creation of an international computer file of technical information on geothermal wells and fields, the development of studies and reports on direct applications, geothermal fluid injection and small power plants, and the operation of the visiting scientist program. In the United States, the computer file has aready proven useful in the development of reservoir models and of chemical geothermometers. The state-of-the-art report on direct uses of geothermal energy is proving to be a valuable resource document for laypersons and experts in an area of increasing interest to many countries. Geothermal fluid injection studies in El Salvador, New Zealand, and the United States have been assisted by the Reservoir Assessment Substudy and have led to long-range reservoir engineering studies in Mexico. At least seven small geothermal power plants are in use or have been planned for construction around the world since the Small Power Plant Substudy was instituted--at least partial credit for this increased application can be assigned to the CCMS Geothermal Pilot Study.

Report of the State Geothermal Resources Task Force, State of California  

DOE Green Energy (OSTI)

The State Geothermal Resources Task Force has investigated the status of geothermal resources and development in California and in this report offers recommendations for overcoming obstacles facing increased utilization of this significant natural resource. For the most part, these recommendations are short-term solutions to immediate problems and would not radically change the roles of governmental agencies currently regulating geothermal development. The Task Force concludes that geothermal operations have been hindered by the lack of a statewide policy on geothermal development. This has resulted in instances where industry has been forced to comply with conflicting governmental policies toward geothermal energy development and environmental protection. The Task Force therefore recommends legislation establishing a statewide policy to encourage geothermal development consistent with environmental quality standards. In addition to geothermal resources suitable for the production of electrical power, California has extensive undeveloped hot water reservoirs suitable for direct thermal applications. The Energy Resources Conservation and Development Commission and the US Geological Survey have concluded that these resources, if developed, could make a significant contribution to satisfying California's energy needs. The Task Force therefore recommends establishing a statewide policy to encourage the use of non-electric hot water geothermal resources for commercial and non-commercial uses where the development is consistent with environmental quality concerns.

Geothermal research, Oregon Cascades: Final technical report  

DOE Green Energy (OSTI)

Previous USDOE-funded geothermal studies have produced an extensive temperature gradient and heat flow data base for the State of Oregon. One of the important features identified as a result of these studies is a rapid transition from heat flow values on the order of 40 mW/m/sup 2/ in the Willamette Valley and Western Cascades to values of greater than or equal to100 mW/m/sup 2/ in the High Cascades and the eastern portion of the Western Cascades. These data indicate that the Cascade Range in Oregon has potential as a major geothermal province and stimulated much of the later work completed by government agencies and private industry. Additional data generated as a result of this grant and published in DOGAMI Open-File Report 0-86-2 further define the location and magnitude of this transition zone. In addition, abundant data collected from the vicinity of Breitenbush and Austin Hot Springs have permitted the formulation of relatively detailed models of these hydrothermal systems. These models are published in DOGAMI Open-File Report 0-88-5. Task 1.2 of the Deliverables section of Amendment M001 is fulfilled by DOGAMI publication GMS-48, Geologic map of the McKenzie Bridge quadrangle, Lane County, Oregon. This map was printed in October, 1988, and is part of the final submission to USDOE. 8 refs.

DOE Green Energy (OSTI)

This issue of the Geothermal Progress Monitor, the 14th since its inception in 1980, highlights the anticipated rapid growth in the use of geothermal heat pumps and documents the continued growth in the use of geothermal energy for power generation, both in this country and abroad. In countries with a relatively large demand for new generation capacity, geothermal, if available, is being called on as a preferable alternative to the use of domestic or imported oil. On the other hand, in this country where current demand for new capacity is less, geothermal energy is commonly being put to use in small power generation units operating on the hot water resource.

The Marysville, Montana Geothermal Project. Final Report  

DOE Green Energy (OSTI)

This report describes the exploration of an anomalous site near Marysville, Montana, where the geothermal heat flow is about 10 times the regional average. The site arouses scientific interest because there are no surface manifestations such as young volcanics, hot springs, geysers, etc., within 20 miles of it. Also, there is significant economic interest in exploring the source of heat as a potential for the generation of electricity. Included herein are independent sections prepared by each contractor. Consequently, there is some overlapping information, generally presented from different viewpoints. The project consists of geophysical surveys in 1973 and 1974, the drilling of the deep well in the summer of 1974 to a depth of 6790 feet, the coring and logging of the well, the supporting scientific studies, and the data analysis. Since so much data are available on the Marysville system, it can serve as a testing and research area to help locate and understand similar systems. (GRA)

Two themes dominate this issue of the Geothermal Progress Monitor, the 15th since its inception in 1980. The first of these is the significance of the government/industry partnership role in geothermal development. This joint effort is reflected in the continued, measured growth in the use of geothermal energy, for both power generation and direct use applications, in this country and abroad, as well as in the development of new, innovative technologies to ensure a bright future for the resource. The second theme is the growing popularity of geothermal heat pumps (GHPs) among utilities, their customers, and federal agencies, all with disparate interests in the technology.

Geothermal energy: opportunities for California commerce. Phase I report  

DOE Green Energy (OSTI)

California's geographic and end-use markets which could directly use low and moderate temperature geothermal resources are ranked and described, as well as those which have the highest potential for near-term commercial development of these resources. Building on previous market surveys, the assessment determined that out of 38 geothermal resource areas with characteristics for direct use development, five areas have no perceived impediments to near-term development: Susanville, Litchfield, Ontario Hot Springs, Lake Elsinore, and the Salton Sea Geothermal Field. Twenty-nine applications were compared with previously selected criteria to determine their near-term potential for direct use of geothermal fluids. Seven categories were found to have the least impediments to development; agriculture and district heating applications are considered the highest. Ten-year projections were conducted for fossil fuel displacement from the higher rated applications. It is concluded that greenhouses have the greatest displacement of 18 x 10/sup 6/ therms per year.

This issue of the Geothermal Progress Monitor (GPM) is the 11th since the inception of the publication in 1980. It continues to synthesize information on all aspects of geothermal development in this country and abroad to permit identification and quantification of trends in the use of this energy technology. In addition, the GPM is a mechanism for transferring current information on geothermal technology development to the private sector, and, over time, provides a historical record for those interested in the development pathway of the resource. In sum, the Department of Energy makes the GPM available to the many diverse interests that make up the geothermal community for the multiple uses it may serve. This issue of the GPM points up very clearly how closely knit many of those diverse interests have become. It might well be called an international issue'' since many of its pages are devoted to news of geothermal development abroad, to the efforts of the US industry to participate in overseas development, to the support given those efforts by federal and state agencies, and to the formation of the International Geothermal Association (IGA). All of these events indicate that the geothermal community has become truly international in character, an occurrence that can only enhance the future of geothermal energy as a major source of energy supply worldwide. 15 figs.

Geothermal energy: opportunities for California commerce. Final report  

DOE Green Energy (OSTI)

This report provides a preliminary engineering and economic assessment of five direct use projects using low and moderate temperature geothermal resources. Each project site and end-use application was selected because each has a high potential for successful, near-term (2 to 5 years) commercial development. The report also includes an extensive bibliography, and reference and contact lists. The five projects are: Wendel Agricultural Complex, East Mesa Livestock Complex, East Mesa Vegetable Dehydration Facility, Calapatria Heating District and Bridgeport Heating District. The projects involve actual investors, resource owners, and operators with varying financial commitments for project development. For each project, an implementation plan is defined which identifies major barriers to development and methods to overcome them. All projects were determined to be potentially feasible. Three of the projects cascade heat from a small-scale electric generator to direct use applications. Small-scale electric generation technology (especially in the 0.5 to 3 MW range) has recently evolved to such a degree as to warrant serious consideration. These systems provide a year-round heating load and substantially improve the economic feasibility of most direct use energy projects using geothermal resources above 200/sup 0/F.

New Mexico Geothermal Commercialization Program. Final report  

SciTech Connect

The New Mexico Geothermal Commercialization Program was developed as a mission-oriented program aimed at accelerating the commercial utilization of geothermal resources. The program provided the US Department of Energy, the State of New Mexico, and the citizens of the state a technical and economic guide for geothermal applications and implementation. This was accomplished by developing market strategies, cultivating public outreach, serving as a broker where appropriate and by providing limited economic and engineering evaluation of specific resource applications. The State of New Mexico used the Commercialization Program as a means to organize, focus and direct all of the state geothermal research, development and demonstration. This action enhanced geothermal development and was strategic to securing $1.8 million from the legislature for geothermal demonstrations. The Commercialization Team identified electrical and direct-use prospects throughout the State. A total of ten sites were classified as inferred electrical grade sites; four sites were classified as potential electrical grade sites; and one site was classified as a proven electrical grade site. Thirty-one sites were classified as direct-use sites: (ten proven, eleven potential and ten inferred). The Commercialization Team defined one geographical area for which the development and utilization of geothermal energy prospects are likely by the year 2020. The Team developed an Area Development Plan for the Rio Grande Rift throughout its entire length within the state.

Enhanced Geothermal Systems (EGS) well construction technology evaluation report.  

DOE Green Energy (OSTI)

Electricity production from geothermal resources is currently based on the exploitation of hydrothermal reservoirs. Hydrothermal reservoirs possess three ingredients critical to present day commercial extraction of subsurface heat: high temperature, in-situ fluid and high permeability. Relative to the total subsurface heat resource available, hydrothermal resources are geographically and quantitatively limited. A 2006 DOE sponsored study led by MIT entitled 'The Future of Geothermal Energy' estimates the thermal resource underlying the United States at depths between 3 km and 10 km to be on the order of 14 million EJ. For comparison purposes, total U.S. energy consumption in 2005 was 100 EJ. The overwhelming majority of this resource is present in geological formations which lack either in-situ fluid, permeability or both. Economical extraction of the heat in non-hydrothermal situations is termed Enhanced or Engineered Geothermal Systems (EGS). The technologies and processes required for EGS are currently in a developmental stage. Accessing the vast thermal resource between 3 km and 10 km in particular requires a significant extension of current hydrothermal practice, where wells rarely reach 3 km in depth. This report provides an assessment of well construction technology for EGS with two primary objectives: (1) Determining the ability of existing technologies to develop EGS wells. (2) Identifying critical well construction research lines and development technologies that are likely to enhance prospects for EGS viability and improve overall economics. Towards these ends, a methodology is followed in which a case study is developed to systematically and quantitatively evaluate EGS well construction technology needs. A baseline EGS well specification is first formulated. The steps, tasks and tools involved in the construction of this prospective baseline EGS well are then explicitly defined by a geothermal drilling contractor in terms of sequence, time and cost. A task and cost based analysis of the exercise is subsequently conducted to develop a deeper understanding of the key technical and economic drivers of the well construction process. Finally, future research & development recommendations are provided and ranked based on their economic and technical significance.

Economic assessment of nine geothermal direct use applications. Final report  

DOE Green Energy (OSTI)

This report provides an economic analysis of nine federally-supported geothermal direct heat applications which were part of DOE's Program Opportunity Notice (PON) program. Three of the projects analyzed were user-owned systems, and six were district heating systems. Five of the nine projects are successful from an economic standpoint and the majority of these projects are in areas where geothermal energy has long been used for heating. The results of this analysis indicate that geothermal energy projects can be economic under certain conditions, but these conditions may not be very widespread.

Hawaii Geothermal Project summary report for Phase I  

DOE Green Energy (OSTI)

Results of Phase I of the Hawaii Geothermal Project (HGP) are reported. It was a multidisciplinary research effort in the following program areas: (1) geophysical--exploratory surveys to define the most favorable areas for geothermal investigations; (2) engineering-- analytical models to assist in interpretation of geophysical results, and studies on energy recovery from hot brine; and (3) socioeconomic--legal and regulatory aspects of ownership and administration of geothermal resources, and economic planning studies on the impact of geothermal resources, and economic planning studies on the impact of geothermal power. The major emphasis of Phase I was on the Geophysical Program, since the issue of if and where geothermal resources exist is crucial to the project. However, parallel studies were initiated in all supporting programs, so that progress was made in identifying and clarifying the technological, environmental, legal, regulatory, social and economic problems that could impede the development of geothermal power in Hawaii. Although the analysis and interpretation of field data are still incomplete, the consensus developed early--both on the basis of preliminary geophysical results and from complementary studies conducted on the Big Island over the past several decades--that an exploratory drilling program would be essential to check out the subsurface conditions predicted by the surveys.

Interagency Geothermal Coordinating Council fifth annual report. Final draft  

DOE Green Energy (OSTI)

Geothermal energy is the natural heat of the earth, and can be tapped as a clean, safe, economical alternative source of energy. Much of the geothermal energy resource is recoverable with current or near-current technology and could make a significant contribution both to increasing domestic energy supplies and to reducing the US dependence on imported oil. Geothermal energy can be used for electric power production, residential and commercial space heating and cooling, industrial process heat, and agricultural process applications. This report describes the progress for fiscal year 1980 (FY80) of the Federal Geothermal Program. It also summarizes the goals, strategy, and plans which form the basis for the FY81 and FY82 program activities and reflects the recent change in national policy affecting Federal research, development and demonstration programs. The Interagency Geothermal Coordinating Council (IGCC) believes that substantial progress can and will be made in the development of geothermal energy. The IGCC goals are: (1) reduce the institutional barriers so that geothermal projects can be on-line in one-half the current time; (2) make moderate temperature resources an economically competitive source of electricity; (3) remove the backlog of noncompetitive lease applications; (4) competitive lease all KGRA lands; and (5) cut the cost of hydrothermal technology by 25%.

Geothermal energy: opportunities for California commerce. Phase I report  

DOE Green Energy (OSTI)

The potential geothermal direct-use energy market and its application to projects in California are assessed. Project identification effort is to be focused on those that have the highest probability for near-term successful commercial operations. Near-term herein means 2 to 5 years for project implementation. Phase I has been focused on defining and assessing: (1) the geothermal direct-use resources that are suitable for near-term utilization; and (2) the generic applications (municipal heating districts, horticultural greenhouse firms, laundries, etc.) that are suitable for near-term projects. Five economic development regions in the state, containing recognized geothermal direct-use resources, have been defined. Thirty-eight direct use resources have been evaluated in these regions. After assessment against pre-selected criteria, twenty-seven have been rated with a priority of I, II or III, thereby qualifying them for further marketing effort. The five areas with a priority of I are summarized. These areas have no perceived impediments to near-term development. Twenty-nine generic categories of applications were assessed against previously selected criteria to determine their near term potential for direct use of geothermal fluids. Some twenty industry, commercial and institutional application categories were rated with a priority of I, II or III and warrant further marketing efforts. The seven categories with a priority of I are listed. These categories were found to have the least impediments to near-term application projects.

Report on Hawaii geothermal power plant project  

DOE Green Energy (OSTI)

The Hawaii Geothermal Generator Project is the first power plant in the State of Hawaii to be powered by geothermal energy. This plant, which is located in the Puna District on the Island of Hawaii, produces three (3) megawatts of electricity utilizing the steam phase from the geothermal well. This project represents the climax of the geophysical research efforts going on for two decades in the Hawaiian Islands which resulted in the discovery of a significant reservoir of geothermal energy which could be put to practical use. In 1978 the Department of Energy, in conjunction with the State of Hawaii, entered into negotiations to design and build a power plant. The purpose and objective of this plant was to demonstrate the feasibility of constructing and operating a geothermal power plant located in a remote volcanically active area. A contract was signed in mid 1978 between the Research Corporation of the University of Hawaii (RCUH) and the Department of Energy (DOE). To date, the DOE has provided 8.3 million dollars with the State of Hawaii and others contributing 2.1 million dollars. The cost of the project exceeded its original estimates by approximately 25%. These increases in cost were principally contributed to the higher cost for construction than was originally estimated. Second, the cost of procuring the various pieces of equipment exceed their estimates by 10 to 20 percent, and third, the engineering dollar per man hour rose 20 to 25 percent.

Fairbanks Geothermal Energy Project Final Report  

SciTech Connect

The primary objective for the Fairbanks Geothermal Energy Project is to provide another source of base-load renewable energy in the Fairbanks North Star Borough (FNSB). To accomplish this, Chena Hot Springs Resort (Chena) drilled a re-injection well to 2700 feet and a production well to 2500 feet. The re-injection well allows a greater flow of water to directly replace the water removed from the warmest fractures in the geothermal reservoir. The new production will provide access to warmer temperature water in greater quantities.

NANA Geothermal Assessment Program Final Report  

Science Conference Proceedings (OSTI)

In 2008, NANA Regional Corporation (NRC) assessed geothermal energy potential in the NANA region for both heat and/or electricity production. The Geothermal Assessment Project (GAP) was a systematic process that looked at community resources and the community's capacity and desire to develop these resources. In October 2007, the US Department of Energy's Tribal Energy Program awarded grant DE-FG36-07GO17075 to NRC for the GAP studies. Two moderately remote sites in the NANA region were judged to have the most potential for geothermal development: (1) Granite Mountain, about 40 miles south of Buckland, and (2) the Division Hot Springs area in the Purcell Mountains, about 40 miles south of Shungnak and Kobuk. Data were collected on-site at Granite Mountain Hot Springs in September 2009, and at Division Hot Springs in April 2010. Although both target geothermal areas could be further investigated with a variety of exploration techniques such as a remote sensing study, a soil geochemical study, or ground-based geophysical surveys, it was recommended that on-site or direct heat use development options are more attractive at this time, rather than investigations aimed more at electric power generation.

Geothermal resource assessment, South Dakota: Final report  

SciTech Connect

Seven geothermal aquifers in South Dakota contain an accessible resource base of about 11,207 x 10/sup 18/ J. The potentially productive geothermal aquifers are: Deadwood Formation (Cambrian), Winnipeg Formation + Red River Formation + Englewood Limestone (Ordovician through Devonian), Madison Limestone (Mississippian), Minnelusa Formation (Mississippian-Permian), Inyan Kara Group (Cretaceous), and Newcastle Sandstone (Cretaceous). The resource estimate was obtained by first using heat flow, thermal conductivity, temperature gradient, and stratigraphic data to estimate aquifer temperatures. The heat content of each aquifer was determined from the product of the volumetric heat capacity, aquifer volume, and temperature difference between the aquifer and the mean annual temperature for a 14 x 14 grid of 240 km/sup 2/ cells. Geothermal fluid temperatures range from about 120/sup 0/C in the Deadwood Formation in the Williston Basin to about 30/sup 0/C for the Newcastle Sandstone in south-central South Dakota. The area containing the resource lies largely west of the Missouri River. About 10,000 km/sup 2/ of the resource area is characterized by anomalously high heat flow values greater than 100 mW m/sup -2/.

The design, testing and performance capabilities of a Geothermal Hot Water Pumping System being developed are described. The pumping system is intended to operate submerged in geothermal brine wells for extended periods of time. Such a system confines the hot brine in a closed-loop under pressure to prevent the liquid from flashing into steam, in addition to providing a means for reinjecting cooled water and the contaminants into a return well. The system consists of a single-stage centrifugal pump driven by an oil-cooled, high-speed electric motor with integral heat exchanger. For testing purposes a diesel engine driven 400 Hz generator is used for supplying power to the motor. In some areas where commercial power may not be available, the diesel-generator unit or either a rotating or solid state frequency converter may be used to produce the high frequency power required by the motor. Fabrication of a prototype system and testing of the electric motor at frequencies up to 250 Hz was completed. While testing at 275 Hz it was necessary to terminate the testing when the motor stator was damaged as a result of a mechanical failure involving the motor-dynamometer drive adaptor. Test results, although limited, confirm the design and indicate that the performance is as good, or better than predicted. These results also indicate that the motor is capable of achieving rated performance.

Hoosac tunnel geothermal heat source. Final report  

DOE Green Energy (OSTI)

The Hoosac Rail Tunnel has been analyzed as a central element in a district heating system for the City of North Adams. The tunnel has been viewed as a collector of the earth's geothermal heat and a seasonal heat storage facility with heat piped to the tunnel in summer from existing facilities at a distance. Heated fluid would be transported in winter from the tunnel to users who would boost the temperature with individual heat pumps. It was concluded the tunnel is a poor source of geothermal heat. The maximum extractable energy is only 2200 million BTU (20000 gallons of oil) at 58/sup 0/F. The tunnel is a poor heat storage facility. The rock conductivity is so high that 75% of the heat injected would escape into the mountain before it could be recaptured for use. A low temperature system, with individual heat pumps for temperature boost could be economically attractive if a low cost fuel (byproduct, solid waste, cogeneration) or a cost effective seasonal heat storage were available.

East Mesa geothermal pump test facility (EMPTF). Final report  

DOE Green Energy (OSTI)

The design, fabrication and installation of a geothermal pump test facility (EMPFT) at the DOE geothermal site at East Mesa, California which is capable of testing 70 to 750 horsepower downwell pumps in a controlled geothermal environment were completed. The facility consists of a skid-mounted brine control module, a 160 foot below test well section, a hydraulic turbine for power recovery, a gantry-mounted hoist for pump handling and a 3-phase, 480 VAC, 1200 amp power supply to handle pump electric requirements. Geothermal brine is supplied to the EMPTF from one of the facility wells at East Mesa. The EMPTF is designed with a great amount of flexibility. The 20-inch diameter test well can accommodate a wide variety of pumps. The controls are interactive and can be adjusted to obtain a full complement of pump operation data, or set to maintain constant conditions to allow long-term testing with a minimum of operator support. The hydraulic turbine allows the EMPTF user to recover approximately 46% of the input pump power to help defray the operating cost of the unit. The hoist is provided for material handling and pump servicing and reduces the equipment that the user must supply for pump installation, inspection and removal.

Utah State Prison Space Heating with Geothermal Heat - Resource Assessment Report Crystal Hot Springs Geothermal Area  

DOE Green Energy (OSTI)

Reported herein is a summary of work conducted under the Resource Assessment Program-Task 2, for the Utah State Prison Geothermal Space Heating Project at Crystal Hot Springs, Draper, Utah. Assessment of the geothermal resource in and around the Utah State Prison property began in october of 1979 with an aeromagnetic and gravity survey. These tasks were designed to provide detailed subsurface structural information in the vicinity of the thermal springs so that an informed decision as to the locations of test and production holes could be made. The geophysical reconnaissance program provided the structural details needed to focus the test drilling program on the most promising production targets available to the State Prison. The subsequent drilling and well testing program was conducted to provide information to aid fin the siting and design of a production well and preliminary design activities. As part of the resource assessment portion of the Utah State Prison Geothermal Project, a program for periodic geophysical monitoring of the Crystal Hot Springs resource was developed. The program was designed to enable determination of baseline thermal, hydraulic, and chemical characteristics in the vicinity of Crystal Hot Springs prior to production and to provide a history of these characteristics during resource development.

Geotechnical Environmental Aspects of Geothermal Power Generation at Heber, Imperial Valley, California. Topical report 1  

DOE Green Energy (OSTI)

This report presents a portion of the results from a one-year feasibility study sponsored by the Electric Power Research Institute (EPRI) to assess the feasibility of constructing a 25-50 MWe geothermal power plant using low salinity hydrothermal fluid as the energy source. The impact of power generation from hydrothermal resources on subsurface water flow, seismicity and subsidence are of acute interest in the determination of the environmental acceptance of geothermal energy. At the same time, the experience and data bases in these areas are very limited. The objective of the project was to assess the technical, geotechnical, environmental and economic feasibility of producing electricity from hydrothermal resources like those known to exist in the US. The objective of this part of the study was to investigate the geotechnical aspects of geothermal power generation and their relationship to environmental impacts in the Imperial Valley of California. This report discusses geology, geophysics, hydrogeology, seismicity and subsidence in terms of the availability of data, state-of-the-art analytical techniques, historical and technical background and interpretation of current data. it also discusses estimates of the impact of these geotechnical factors on the environment in the Imperial Valley, if geothermal development proceeds.

Geothermal direct contact heat exchange. Final report  

DOE Green Energy (OSTI)

A glass direct contact heat exchange column was operated in the laboratory. The column was operated at atmospheric pressure using hot water and normal hexane. Column internals testing included an empty column, sieve trays, disk-and-doughnut trays, and two types of packing. Operation was very smooth in all cases and the minimum temperature approaches varied from less than 1/sup 0/C for packing to 13/sup 0/C for the empty column. High heat transfer rates were obtained in all cases, however, columns should be sized on the basis of liquid and vapor traffic. The solubilities of hydrocarbons were determined for normal hexane, pentane and butane in water and sodium chloride and calcium chloride brines at various temperatures. The values seem to be internally consistent and salt content was found to depress hydrocarbon solubility. Laboratory stripping tests showed that gas stripping can be used to remove hydrocarbon from reject hot water from the direct contact heat exchange column. Although the gas volumes required are small, stripping gas requirements cannot be accurately predicted without testing. A computer program was used to study the effect of operating variables on the thermodynamic cycle efficiencies. Optimum efficiencies for the moderate brine conditions studied were obtained with isopentane as working fluid and relatively low operating pressure. A preliminary design for a 50 MWe plant was prepared and plant capital cost and operating cost were estimated. These costs were combined with previously developed brine production and power transmission costs to provide an estimate of the cost of delivered power for a geothermal field at Heber, California. A pilot plant program is described that would be suitable for continuing the investigation of the direct contact process in the field. The program includes a suggested schedule and the estimated cost.

Report on the U.S. DOE Geothermal Technologies Program's 2009 Risk Analysis  

DOE Green Energy (OSTI)

NREL conducted an annual program risk analysis on behalf of the U.S. Department of Energy Geothermal Technologies Program (GTP). NREL implemented a probabilistic risk analysis of GTP-sponsored research, development, and demonstration (RD&D) work, primarily for enhanced geothermal systems (EGS). The analysis examined estimates of improvement potential derived from program RD&D work for two types of technology performance metric (TPM): EGS-enabling technologies potential and EGS cost improvement potential. Four risk teams (exploration, wells/pumps/tools, reservoir engineering, and power conversion) comprised of industry experts, DOE laboratory researchers, academic researchers, and laboratory subcontractors estimated the RD&D impacts and TPM-improvement probability distributions. The assessment employed a risk analysis spreadsheet add-in that uses Monte Carlo simulation to drive the Geothermal Electric Technology Evaluation Model (GETEM). The GETEM-based risk analysis used baseline data from the experts' discussion of multiple reports and data sources. Risk results are expressed in terms of each metric's units and/or the program's top-level metric: levelized costs of electricity (LCOE). Results--both qualitative comments and quantitative improvement potential--are thorough and cohesive in three of the four expert groups. This conference paper summarizes the industry's current thinking on various metrics and potential for research improvement in geothermal technologies.

Auburn low-temperature geothermal well. Volume 6. Final report  

DOE Green Energy (OSTI)

The Auburn well was drilled to explore for low temperature geothermal resources in central New York State. The Auburn site was selected based on: its proximity to the Cayuga County anomaly (30/sup 0/C/km), its favorable local geological conditions and the potential to provide hot water and space heating to two educational facilities. The well was drilled to a total depth of 5250 feet and into the Pre-Cambrian Basement. The well was extensively logged, flow and stress tested, hydraulically stimulated, and pump (pressure transient analysis) tested. The low-temperature geothermal potential was assessed in terms of: geological environment; hydrological conditions; reservoir characteristics; and recoverable hydrothermal reserves. The average geothermal gradient was measured to be as high as 26.7/sup 0/C/km with a bottom-hole temperature of 126/sup 0/ +- 1/sup 0/F. The proved volumetric resources were estimated to be 3.0 x 10/sup 6/ stock tank barrels (STB) with a maximum initial deliverability of approx.11,600 STB/D and a continuous deliverability of approx.3400 STB/D. The proved hydrothermal reserves were estimated to be 21.58 x 10/sup 10/ Btu based on a volumetric component (4.13 x 10/sup 10/ Btu), and a reinjection component (17.45 x 10/sup 10/ Btu). The conclusion was made that the Auburn low-temperature reservoir could be utilized to provide hot water and space heating to the Auburn School District.

West Texas geothermal resource assessment. Part I. Geothermal exploration in Trans-Pecos, Texas. Final report  

Science Conference Proceedings (OSTI)

All of the new drilling for geothermal gradient and heat flow studies have been concentrated in an area near Hueco Tanks State Park. Interest in the area was raised by the silica geothermometry map of Hoffer (1979) and its proximity to El Paso, which is less than 25 miles away and expanding rapidly toward the area of geothermal interest. Several industries in El Paso appear to be potential users of non-electrical grade hot waters. A total of 14 holes have been drilled for geothermal gradient and heat-flow measurements. Of these, 12 were 50 meters deep and all but two had gradients in excess of 100/sup 0/C/km, one having a gradient as high as 306/sup 0/C/km. Of the remaining two, one penetrated bedrock at about 50 meters and was drilled to a total depth of 125 meters. The gradient in the limestone bedrock is 170/sup 0/C/km and the heat flow is about 11 x 10/sup -6/cal/cm/sup 2/ sec. This is the highest heat flow thus far reported for a locality in the Rio Grande Rift. The last hole is 300 meters deep and has a gradient of 142/sup 0/C/km and a heat flow of 9 x 10/sup -6/cal/cm/sup 2/ sec. The Hueco Tanks site is very promising for at least space heating applications of hot water. Based on the 300 meter hole the potential for electricity grade temperatures still exist, but the tight limestone bedrock may require hot dry rock extraction technology.

Geothermal Energy Development in the Eastern United States. Final Report  

DOE Green Energy (OSTI)

This document represents the final report from the Applied Physics Laboratory (APL) of The Johns Hopkins University on its efforts on behalf of the Division of Geothermal Energy (DGE) of the Department of Energy (DOE). For the past four years, the Laboratory has been fostering development of geothermal energy in the Eastern United States. While the definition of ''Eastern'' has changed somewhat from time to time, basically it means the area of the continental United States east of the Rocky Mountains, plus Puerto Rico but excluding the geopressured regions of Texas and Louisiana. During these years, the Laboratory developed a background in geology, hydrology, and reservoir analysis to aid it in establishing the marketability of geothermal energy in the east. Contrary to the situation in the western states, the geothermal resource in the east was clearly understood to be inferior in accessible temperature. On the other hand, there were known to be copious quantities of water in various aquifers to carry the heat energy to the surface. More important still, the east possesses a relatively dense population and numerous commercial and industrial enterprises, so that thermal energy, almost wherever found, would have a market. Thus, very early on it was clear that the primary use for geothermal energy in the east would be for process heat and space conditioning--heating and cool electrical production was out of the question. The task then shifted to finding users colocated with resources. This task met with modest success on the Atlantic Coastal Plain. A great deal of economic and demographic analysis pinpointed the prospective beneficiaries, and an intensive ''outreach'' campaign was mounted to persuade the potential users to invest in geothermal energy. The major handicaps were: (1) The lack of demonstrated hydrothermal resources with known temperatures and expected longevity; and (2) The lack of a ''bellwether'' installation for entrepreneurs to see, touch, and emulate. It is only at the present time that these two issues appear to be on the way to resolution by DGE user-coupled programs in the east.

UCSD geothermal chemistry program; Annual progress report, FY 1989  

DOE Green Energy (OSTI)

The development of a geothermal resource requires a considerable financial commitment. As in other energy extraction ventures, the security of this investment can be jeopardized by the uncertain behavior of the resource under operating conditions. Many of the most significant problems limiting the development of geothermal power are related to the chemical properties of the high temperature and highly pressured formation fluids from which the energy is extracted. When the pressure and temperature conditions on these fluids are changed either during the production phase (pressure changes) or during the extraction phase (temperature changes) of the operation, the fluids which were originally in equilibrium under the new conditions by precipitation of solid materials (scales) or release of dissolved gases (some toxic) in the formation and well bores or in the plant equipment. Unfortunately, predicting the behavior of the production fluids is difficult, because it is a function of many variables. In order to address these problems the Department of Energy is developing a computer model describing the chemistry of geothermal fluids. The model under development at UCSD is based on recent progress in the physical chemistry of concentrated aqueous solutions, and is covered in this report.

Guidelines to the Preparation of Environmental Reports for Geothermal Development Projects  

DOE Green Energy (OSTI)

The US Energy Research and Development Administration (ERDA) through its Division of Geothermal Energy (DGE) is the federal agency responsible for certain actions that pertain to the development of geothermal resources. Such resources include (1) all products of geothermal processes, embracing indigenous steam, geopressured fluids, hot water, and brines; (2) steam and other gases, hot water and hot brines resulting from water, and natural gas or other fluids introduced into geothermal formations; (3) any by-products derived from geothermal resources, such as minerals or gases. By-products must either have a value less than 75% of the value of the geothermal resources from which they are derived or must not be of sufficient value alone to warrant extraction and production. in order to encourage the development of geothermal resources, ERDA conducts a program to assess those resources and to establish the technical, economic, and environmental acceptability of geothermal technologies. This program includes some proposed actions that could affect the environment. As a means of obtaining information essential to satisfying the requirements of NEAP and its own regulations (10 CFR Part 711), ERDA requests that certain participants in the agency's programmatic activities submit an environmental report. The report describes the proposed programmatic activities and considers the potential impacts of those activities with respect to the existing environment. This guidelines document has been developed to provide assistance to participants in the preparation of environmental reports about geothermal activities.

Assessing geothermal energy potential in upstate New York. Final report  

DOE Green Energy (OSTI)

The potential of geothermal energy for future electric power generation in New York State is evaluated using estimates of temperatures of geothermal reservoir rocks. Bottom hole temperatures from over 2000 oil and gas wells in the region were integrated into subsurface maps of the temperatures for specific geothermal reservoirs. The Theresa/Potsdam formation provides the best potential for extraction of high volumes of geothermal fluids. The evaluation of the Theresa/Potsdam geothermal reservoir in upstate New York suggests that an area 30 miles east of Elmira, New York has the highest temperatures in the reservoir rock. The Theresa/Potsdam reservoir rock should have temperatures about 136 {degrees}C and may have as much as 450 feet of porosity in excess of 8%. Estimates of the volumes of geothermal fluids that can be extracted are provided and environmental considerations for production from a geothermal well is discussed.

Geothermal Loan Guaranty Program  

DOE Green Energy (OSTI)

Presently the US imports a large proportion of its petroleum requirements. This dependence on foreign petroleum has had a major impact on our economy. As a result, the Federal government is sponsoring programs to offset this foreign reliance by conservation of oil and gas, conversion of petroleum using facilities to coal and nuclear energy and the development of alternate sources of energy. One of the most acceptable alternate resources is geothermal. It offers an environmentally sound energy resource, can be developed at reasonable cost in comparison to other forms of energy and has a long term production capacity. On September 3, 1974, the Geothermal Energy Research Development and Demonstration Act was enacted to further the research, development and demonstration of geothermal energy technologies. This Act also established the Geothermal Loan Guaranty Program to assist in the financing of geothermal resource development, both electrical and non-electrical. The highlights of that Guaranty Program are detailed in this report.

Great Western Malting Company geothermal project, Pocatello, Idaho. Final report  

DOE Green Energy (OSTI)

The Great Western Malting Company recently constructed a barley malting facility in Pocatello, Idaho, designed to produce 6.0 million bushels per year of brewing malt. This facility uses natural gas to supply the energy for germination and kilning processes. The escalating cost of natural gas has prompted the company to look at alternate and more economical sources of energy. Trans Energy Systems has investigated the viabiity of using geothermal energy at the new barley processing plant. Preliminary investigations show that a geothermal resource probably exists, and payback on the installation of a system to utilize the resource will occur in under 2 years. The Great Western Malting plant site has geological characteristics which are similar to areas where productive geothermal wells have been established. Geological investigations indicate that resource water temperatures will be in the 150 to 200/sup 0/F range. Geothermal energy of this quality will supply 30 to 98% of the heating requirements currently supplied by natural gas for this malting plant. Trans Energy Systems has analyzed several systems of utilizing the geothermal resource at the Great Western barley malting facility. These systems included: direct use of geothermal water; geothermal energy heating process water through an intermediary heat exchanger; coal or gas boosted geothermal systems; and heat pump boosted geothermal system. The analysis examined the steps that are required to process the grain.

Pueblo of Jemez Geothermal Feasibility Study Fianl Report  

DOE Green Energy (OSTI)

This project assessed the feasibility of developing geothermal energy on the Pueblo of Jemez, with particular attention to the Red Rocks area. Geologic mapping of the Red Rocks area was done at a scale of 1:6000 and geophysical surveys identified a potential drilling target at a depth of 420 feet. The most feasible business identified to use geothermal energy on the reservation was a greenhouse growing culinary and medicinal herbs. Space heating and a spa were identified as two other likely uses of geothermal energy at Jemez Pueblo. Further geophysical surveys are needed to identify the depth to the Madera Limestone, the most likely host for a major geothermal reservoir.

Unalaska geothermal exploration project. Electrical power generation analysis. Final report  

DOE Green Energy (OSTI)

The objective of this study was to determine the most cost-effective power cycle for utilizing the Makushin Volcano geothermal resource to generate electricity for the towns of Unalaska and Dutch Harbor. It is anticipated that the geothermal power plant would be intertied with a planned conventional power plant consisting of four 2.5 MW diesel-generators whose commercial operation is due to begin in 1987. Upon its completion in late 1988, the geothermal power plant would primarily fulfill base-load electrical power demand while the diesel-generators would provide peak-load electrical power and emergency power at times when the geothermal power plant would be partially or completely unavailable. This study compares the technical, environmental, and economic adequacy of five state-of-the-art geothermal power conversion processes. Options considered are single- and double-flash steam cycles, binary cycle, hybrid cycle, and total flow cycle.

Geothermal pump test facility. Final report, July 1977--July 1978  

DOE Green Energy (OSTI)

The design configuration and fabrication description of a transportable geothermal pump test facility are discussed. The test facility, consisting of a test rig and data acquisition system trailer, provides the user with the unique opportunity to develop and calibrate geothermal pumps with less liability and risk, and at lower cost than would be incurred by actually installing the pump in a geothermal well. Pump tests may be performed using either domestic water, heated by pumping energy, or by using actual geothermal brines supplied directly to the test rig which would be located adjacent to the well. The geothermal pump test facility is completely self supporting and requires only an electrical supply source to become fully operational. Information and discussion presented provide substantive background, design and operational capabilities, and pertinent fabrication details.

Report to the Legislature on the California Energy Commission's Geothermal Development Grant Program for Local Governments  

DOE Green Energy (OSTI)

This report documents the California Energy Commission's administration of its Geothermal Development Grant Program for Local Governments. The Energy Commission established this program as a result of the passage of Assembly Bill 1905 (Bosco) in 1980. This legislation established the mechanism to distribute the state's share of revenues received from the leasing of federal mineral reserves for geothermal development. The federal government deposits these revenues in the Geothermal Resources Development Account (GRDA) created by AB 1905. The state allocates funds from the GRDA to the California Parklands and Renewable Resources Investment Fund, the counties of origin where the federal leases are located, and the Energy Commission. The legislation further directs the Energy Commission to disburse its share as grants to local governments to assist with the planning and development of geothermal resources. Activities which are eligible for funding under the Energy Commission's grant program include resource development projects, planning and feasibility studies, and activities to mitigate the impacts of existing geothermal development.

Use of slim holes for geothermal exploration and reservoir assessment: A preliminary report on Japanese experience  

DOE Green Energy (OSTI)

The publicly available Japanese data on the use of slim holes in geothermal exploration and reservoir assessment are reviewed in this report. Slim holes have been used for (1) obtaining core for geological studies, (2) delineating the stratigraphic structure, (3) characterizing reservoir fluid state (pressure, temperature, etc.), and (4) defining the permeability structure for reservoir assessment. Examples of these uses of slim hole data are presented from the Hohi Geothermal Area and the Sumikawa Geothermal Field. Discharge data from slim holes and production wells from the Oguni Geothermal Field indicate that it may be possible to infer the discharge rate of production wells based on slim hole measurements. The Japanese experience suggests that slim holes can provide useful data for cost-effective geothermal reservoir assessment. Therefore, plans for a full scale evaluation of Japanese slim hole data are outlined.

Strategic plan for the geothermal energy program  

SciTech Connect

Geothermal energy (natural heat in the Earth`s crust) represents a truly enormous amount of energy. The heat content of domestic geothermal resources is estimated to be 70,000,000 quads, equivalent to a 750,000-year supply of energy for the entire Nation at current rates of consumption. World geothermal resources (exclusive of resources under the oceans) may be as much as 20 times larger than those of the US. While industry has focused on hydrothermal resources (those containing hot water and/or steam), the long-term future of geothermal energy lies in developing technology to enable use of the full range of geothermal resources. In the foreseeable future, heat may be extracted directly from very hot rocks or from molten rocks, if suitable technology can be developed. The US Department of Energy`s Office of Geothermal Technologies (OGT) endorses a vision of the future in which geothermal energy will be the preferred alternative to polluting energy sources. The mission of the Program is to work in partnership with US industry to establish geothermal energy as a sustainable, environmentally sound, economically competitive contributor to the US and world energy supply. In executing its mission and achieving its long-term vision for geothermal energy, the Program has identified five strategic goals: electric power generation; direct use applications and geothermal heat pumps; international geothermal development; science and technology; and future geothermal resources. This report discusses the objectives of these five goals.

New Heat Flow Models in Fractured Geothermal Reservoirs - Final Report  

DOE Green Energy (OSTI)

This study developed new analytical models for predicting the temperature distribution within a geothermal reservoir following reinjection of water having a temperature different from that of the reservoir. The study consisted of two parts: developing new analytical models for the heat conduction rate into multi-dimensional, parallelepiped matrix blocks and developing new analytical models for the advance of the thermal front through the geothermal reservoir. In the first part of the study, a number of semi-empirical models for the multi-dimensional heat conduction were developed to overcome the limitations to the exact solutions. The exact solution based on a similarity solution to the heat diffusion equation is the best model for the early-time period, but fails when thermal conduction fronts from opposing sides of the matrix block merge. The exact solution based on an infinite series solution was found not to be useful because it required tens of thousands of terms to be include d for accuracy. The best overall model for the entire conduction time was a semi-empirical model based on an exponential conduction rate. In the second part of the study, the early-time period exact solution based on similarity methods and the semi-empirical exponential model were used to develop new analytical models for the location of the thermal front within the reservoir during injection. These equations were based on an energy balance on the water in the fractured network. These convective models allowed for both dual and triple porosity reservoirs, i.e., one or two independent matrix domains. A method for incorporating measured fracture spacing distributions into these convective models was developed. It was found that there were only minor differences in the predicted areal extent of the heated zone between the dual and triple porosity models. Because of its simplicity, the dual porosity model is recommended. These new models can be used for preliminary reservoir studies. Although they are not as accurate as numerical simulators, they are simple, easy and inexpensive to use. These new models can be used to get general information about reservoir behavior before committing to the considerable greater expense of numerical simulation.

Silica recovery and control in Hawaiian geothermal fluids. Final report  

DOE Green Energy (OSTI)

A series of experiments was performed to investigate methods of controlling silica in waste geothermal brines produced at the HGP-A Generator Facility. Laboratory testing has shown that the rate of polymerization of silica in the geothermal fluids is highly pH dependent. At brine pH values in excess of 8.5 the suspension of silica polymers flocculated and rapidly precipitated a gelatinous silica mass. Optimum flocculation and precipitation rates were achieved at pH values in the range of 10.5 to 11.5. The addition of transition metal salts to the geothermal fluids similarly increased the rate of polymerization as well as the degree of precipitation of the silica polymer from suspension. A series of experiments performed on the recovered silica solids demonstrated that methanol extraction of the water in the gels followed by critical point drying yielded surface areas in excess of 300 M{sup 2}/g and that treatment of the dried solids with 2 N HCl removed most of the adsorbed impurities in the recovered product. A series of experiments tested the response of the waste brines to mixing with steam condensate and non-condensable gases.The results demonstrated that the addition of condensate and NCG greatly increased the stability of the silica in the geothermal brines. They also indicated that the process could reduce the potential for plugging of reinjection wells receiving waste geothermal fluids from commercial geothermal facilities in Hawaii. Conceptual designs were proposed to apply the gas re-combination approach to the disposal of geothermal waste fluids having a range of chemical compositions. Finally, these designs were applied to the geothermal fluid compositions found at Cerro Prieto, Ahuachapan, and Salton Sea.

Hawaii Geothermal Project: initial Phase II progress report  

DOE Green Energy (OSTI)

Results of Phase I of the Hawaii Geothermal Project (HGP), which consisted of a two-year study on the potential of geothermal energy for the Big Island of Hawaii, are reviewed. One conclusion from Phase I was that preliminary results looked sufficiently encouraging to warrant the drilling of the first experimental geothermal well in the Puna area of the Big Island. During the first two months of drilling, parallel activity has continued in all research and support areas. Additional gravity, seismic, and electrical surveys were conducted; water and rock samples were collected; and analysis and interpretation of data has proceeded. Earlier work on mathematical and physical modeling of geothermal reservoirs was expanded; analysis of liquid-dominated geothermal systems continued; and studies on testing of geothermal wells were initiated. An environmental assessment statement of HGP No. 1 was prepared and baselines established for crucial environmental parameters. Economic, legal, and regulatory studies were completed and alternatives identified for the development of geothermal power in Hawaii. Early stages of the drilling program proceeded slowly. The initial 9 7/8-inch drill hole to 400 feet, as well as each of the three passes required to open the hole to 26 inches, were quite time consuming. Cementing of the 20-inch surface casing to a depth of 400 feet was successfully accomplished, and drilling beyond that depth has proceeded at a reasonable rate. Penetration below the surface casing to a depth of 1050 feet was accomplished at a drilling rate in excess of 150 feet per day, with partial circulation over the entire range.

Study of practical cycles for geothermal power plants. Final report  

SciTech Connect

A comparison is made of the performance and cost of geothermal power cycles designed specifically, utilizing existing technology, to exploit the high temperature, high salinity resource at Niland and the moderate temperature, moderately saline resource at East Mesa in California's Imperial Valley. Only two kinds of cycles are considered in the analysis. Both employ a dual flash arrangement and the liberated steam is either utilized directly in a condensing steam turbine or used to heat a secondary working fluid in a closed Rankine (binary) cycle. The performance of several organic fluids was investigated for the closed cycle and the most promising were selected for detailed analysis with the given resource conditions. Results show for the temperature range investigated that if the noncondensible gas content in the brine is low, a dual flash condensing steam turbine cycle is potentially better in terms of resource utilization than a dual flash binary cycle. (The reverse is shown to be true when the brine is utilized directly for heat exchange.) It is also shown that despite the higher resource temperature, the performance of the dual flash binary cycle at Niland is degraded appreciably by the high salinity and its output per unit of brine flow is almost 20 percent lower than that of the steam turbine cycle at East Mesa. Turbine designs were formulated and costs established for power plants having a nominal generating capacity of 50 MW. Three cycles were analyzed in detail. At East Mesa a steam turbine and a binary cycle were compared. At Niland only the binary cycle was analyzed since the high CO/sub 2/ content in the brine precludes the use of a steam turbine there. In each case only the power island equipment was considered and well costs and the cost of flash separators, steam scrubbers and piping to the power plant boundary were excluded from the estimate.

Geothermal energy resource assessment of parts of Alaska. Final report  

DOE Green Energy (OSTI)

The central Seward Peninsula was the subject of a geological, geophysical and geochemical reconnaissance survey during a 30-day period in the summer of 1980. The survey was designed to investigate the geothermal energy resource potential of this region of Alaska. A continental rift system model was proposed to explain many of the Late Tertiary-to-Quaternary topographic, structural, volcanic and geothermal features of the region. Geologic evidence for the model includes normal faults, extensive fields of young alkalic basalts, alignment of volcanic vents, graben valleys and other features consistent with a rift system active from late Miocene time to the present. Five traverses crossing segments of the proposed rift system were run to look for evidence of structure and geothermal resources not evident from surface manifestation. Gravity, helium and mercury soil concentrations were measured along the traverses. Seismic, resistivity, and VLF studies are presented.

Community Geothermal Technology Program: Experimental lumber drying kiln. Final report  

DOE Green Energy (OSTI)

Goals were to demonstrate feasibility of using the geothermal waste effluent from the HGP-A well as a heat source for a kiln operation to dry hardwoods, develop drying schedules, and develop automatic systems to monitor/control the geothermally heated lumber dry kiln systems. The feasibility was demonstrated. Lumber was dried in periods of 2 to 6 weeks in the kiln, compared to 18 months air drying and 6--8 weeks using a dehumidified chamber. Larger, plate-type heat exchangers between the primary fluid and water circulation systems may enable the kiln to reach the planned temperatures (180--185 F). However, the King Koa partnership cannot any longer pursue the concept of geothermal lumber kilns.

Public service impacts of geothermal development: cumulative impacts study of the Geysers KGRA. Final staff report  

DOE Green Energy (OSTI)

The number of workers currently involved in the various aspects of geothermal development in the Geysers are identified. Using two different development scenarios, projections are made for the number of power plants needed to reach the electrical generation capacity of the steam resource in the Geysers. The report also projects the cumulative number of workers needed to develop the steam field and to construct, operate, and maintain these power plants. Although the number of construction workers fluctuates, most are not likely to become new, permanent residents of the KGRA counties. The administrative and public service costs of geothermal development to local jurisdications are examined, and these costs are compared to geothermal revenues accruing to the local governments. Revenues do not cover the immediate fiscal needs resulting from increases in local road maintenance and school enrollment attributable to geothermal development. Several mitigation options are discussed and a framework presented for calculating mitigation costs for school and road impacts.

Utilization of U. S. geothermal resources. Final report  

SciTech Connect

This study is concerned with U.S. geothermal resources, their potential for commercial utilization by electric utilities between now and the year 2000, and their impact on the utility industry. USGS estimates of the resources in identified hydrothermal systems were extrapolated to the undiscovered resources marked by hot springs, and further to the blind resources between hot spring areas within the tectonic belts. The resulting estimate of the total hydrothermal resource to a depth of 10,000 ft. is about 100,000 MWe for 30 years with about one-half in undiscovered blind resources, one-fourth in undiscovered hot spring resources, and one-fourth in identified systems. Water rates and direct capital costs for geothermal power plants were evaluated as functions of resource temperature, together with costs and expected flowrates for geothermal wells. Combining these results with the temperature distribution of identified hydrothermal systems, a current supply curve for geothermal energy wa s made. This shows an estimated 20,000 MWe for 30 years potentially producible with current technology from identified resources for direct capital costs of $800/KW or less. The projected supply curve shows an estimated 30,000 to 60,000 MWe for 30 years potentially available at $800/KW or less, in 1976 dollars, taking account of estimated undiscovered resources and probable technical advances.

DOE Green Energy (OSTI)

The progress of geothermal development during the past three years, county activities in support of geothermal development, and current challenges and future needs of the geothermal industry and the county are summarized. Exploration activities have resulted in the identification and definition of three additional Known Geothermal Resource Areas (KGRAs) during the grant period: the Westmorland KGRA, the East Brawley KGRA, both in 1980, and the South Brawley KGRA in 1982. Exploration is continuing in other areas of the county as well. Three 10 megawatt power plants have begun operations during the grant period: the Magma East Mesa 10 Megawatt Binary Power Plant, the Union/Southern California Edison 10 Megawatt Flash Power Plant in Brawley, both beginning operations in 1980, and the Union/Southern California Edison 10 Megawatt Flash Power Plant at the Salton Sea, initiating operations in 1982. Three commercial power plants are scheduled to begin construction during late 1982 or early 1983. Groundbreaking for the Heber Binary Project is scheduled for November 1982. Site work has already begun for the Heber Flash Power Plant. The Magma 28 megawatt power plant at the Salton Sea is to begin construction in early 1983. Two commercial power plants are in planning stages. (MHR)

DOE geothermal R&D program focused on facilitating long-term, cost-effective private resource development  

SciTech Connect

Analyses conducted in support of the National Energy Strategy projected that as much as 22,000 megawatts of cost-effective, moderate-temperature geothermal energy are available to the U.S. over the long-term, or to the year 2030. Thus, the primary hydrothermal technology research goal of the Department's Geothermal Division is to facilitate the ability of the private sector to exploit competitively this large source of energy up to that capacity level or greater. The primary mechanism for implementing this goal is an R&D core program cost-shared with industry focused on major cost-sensitive technology areas: exploration technology, reservoir engineering and management, and drilling. The NES analyses also indicated that electricity generated with energy derived from hot dry rock could be a geographically dispersed, logical follow-on to hydrothermal electricity in the longer term. In order to demonstrate whether energy at useful temperatures can be extracted over extended periods at competitive energy prices, a long-term flow test of an experimental HDR system will be conducted. This paper describes DOE's current participation in R&D activities leading to the development of ''cutting edge'' technology that will serve the geothermal industry's interest well into the next century.

Geothermal Power and Interconnection: The Economics of Getting to Market  

Science Conference Proceedings (OSTI)

This report provides a baseline description of the transmission issues affecting geothermal technologies. The report begins with a comprehensive overview of the grid, how it is planned, how it is used, and how it is paid for. The report then overlays onto this 'big picture' three types of geothermal technologies: conventional hydrothermal systems; emerging technologies such as enhanced engineered geothermal systems (EGS) and geopressured geothermal; and geothermal co-production with existing oil and gas wells. Each category of geothermal technology has its own set of interconnection issues, and these are examined separately for each. The report draws conclusions about each technology's market affinities as defined by factors related to transmission and distribution infrastructure. It finishes with an assessment of selected markets with known geothermal potential, identifying those that offer the best prospects for near-term commercial development and for demonstration projects.

Many binary-cycle geothermal plants use air as the heat rejection medium. Usually this is accomplished by using an air-cooled condenser (ACC) system to condense the vapor of the working fluid in the cycle. Many air-cooled plants suffer a loss of production capacity of up to 50% during times of high ambient temperatures. Use of limited amounts of water to supplement the performance of ACCs is investigated. Deluge cooling is found to be one of the least-cost options. Limiting the use of water in such an application to less than one thousand operating hours per year can boost plant output during critical high-demand periods while minimizing water use in binary-cycle geothermal power plants.

Heat pumps for geothermal applications: availability and performance. Final report  

SciTech Connect

A study of the performance and availability of water-source heat pumps was carried out. The primary purposes were to obtain the necessary basic information required for proper evaluation of the role of water-source heat pumps in geothermal energy utilization and/or to identify the research needed to provide this information. The Search of Relevant Literature considers the historical background, applications, achieved and projected performance evaluations and performance improvement techniques. The commercial water-source heat pump industry is considered in regard to both the present and projected availability and performance of units. Performance evaluations are made for units that use standard components but are redesigned for use in geothermal heating.

Field testing advanced geothermal turbodrill (AGT). Phase 1 final report  

DOE Green Energy (OSTI)

Maurer Engineering developed special high-temperature geothermal turbodrills for LANL in the 1970s to overcome motor temperature limitations. These turbodrills were used to drill the directional portions of LANL`s Hot Dry Rock Geothermal Wells at Fenton Hill, New Mexico. The Hot Dry Rock concept is to drill parallel inclined wells (35-degree inclination), hydraulically fracture between these wells, and then circulate cold water down one well and through the fractures and produce hot water out of the second well. At the time LANL drilled the Fenton Hill wells, the LANL turbodrill was the only motor in the world that would drill at the high temperatures encountered in these wells. It was difficult to operate the turbodrills continuously at low speed due to the low torque output of the LANL turbodrills. The turbodrills would stall frequently and could only be restarted by lifting the bit off bottom. This allowed the bit to rotate at very high speeds, and as a result, there was excessive wear in the bearings and on the gauge of insert roller bits due to these high rotary speeds. In 1998, Maurer Engineering developed an Advanced Geothermal Turbodrill (AGT) for the National Advanced Drilling and Excavation Technology (NADET) at MIT by adding a planetary speed reducer to the LANL turbodrill to increase its torque and reduce its rotary speed. Drilling tests were conducted with the AGT using 12 1/2-inch insert roller bits in Texas Pink Granite. The drilling tests were very successful, with the AGT drilling 94 ft/hr in Texas Pink Granite compared to 45 ft/hr with the LANL turbodrill and 42 ft/hr with a rotary drill. Field tests are currently being planned in Mexico and in geothermal wells in California to demonstrate the ability of the AGT to increase drilling rates and reduce drilling costs.

New geothermal site identification and qualification. Final report  

DOE Green Energy (OSTI)

This study identifies remaining undeveloped geothermal resources in California and western Nevada, and it estimates the development costs of each. It has relied on public-domain information and such additional data as geothermal developers have chosen to make available. Reserve estimation has been performed by volumetric analysis with a probabilistic approach to uncertain input parameters. Incremental geothermal reserves in the California/Nevada study area have a minimum value of 2,800 grosss MW and a most-likely value of 4,300 gross MW. For the state of California alone, these values are 2,000 and 3,000 gross MW, respectively. These estimates may be conservative to the extent that they do not take into account resources about which little or no public-domain information is available. The average capital cost of incremental generation capacity is estimated to average $3,100/kW for the California/Nevada study area, and $2,950/kW for the state of California alone. These cost estimates include exploration, confirmation drilling, development drilling, plant construction, and transmission-line costs. For the purposes of this study, a capital cost of $2,400/kW is considered competitive with other renewable resources. The amount of incremental geothermal capacity available at or below $2,400/kW is about 1,700 gross MW for the California/Nevada study area, and the same amount (within 50-MW rounding) for the state of California alone. The capital cost estimates are only approximate, because each developer would bring its own experience, bias, and opportunities to the development process. Nonetheless, the overall costs per project estimated in this study are believed to be reasonable.

Geothermal resource assessment for North Dakota. Final Report  

SciTech Connect

Temperatures in four geothermal aquifers, inyan Kara (Cretaceous), Mission Canyon (Mississippian), Duperow (Devonian), and Red River (Ordovician) are in the range for low and moderate temperature geothermal resources within an area of about 130,000 km{sup 2} in North Dakota. The accessible resource base is 13,500 x 10{sup 18} J., which, assuming a recovery factor of 0.001, may represent a greater quantity of recoverable energy than is present in the basin in the form of petroleum. A synthesis of heat flow, thermal conductivity, and stratigraphic data was found to be significantly more accurate in determining formation temperatures than the use of linear temperature gradients derived from bottom hole temperature data. The thermal structure of the Williston Basin is determined by the thermal conductivities of four principal lithologies: Tertiary silts and sands (1.6 W/m/K), Mesozoic shales (1.2 W/m/K), Paleozoic limestones (3.2 W/m/K), and Paleozoic dolomites (3.5 W/m/K). The stratigraphic placement of these lithologies leads to a complex, multi-component geothermal gradient which precludes use of any single component gradient for accurate determination of subsurface temperatures.

Resource engineering and economic studies for direct application of geothermal energy. Draft final report  

SciTech Connect

The feasibility of utilizing geothermal energy at a selected plant in New York State was studied. Existing oil and gas records suggests that geothermal fluid is available in the target area and based on this potential. Friendship Dairies, Inc., Friendship, NY, was selected as a potential user of geothermal energy. Currently natural gas and electricity are used as its primary energy sources. Six geothermal system configurations were analyzed based on replacement of gas or oil-fired systems for producing process heat. Each system was evaluated in terms of Internal Rate of Return on Investment (IRR), and simple payback. Six system configurations and two replaced fuels, representative of a range of situations found in the state, are analyzed. Based on the potential geothermal reserves at Friendship, each of the six system configurations are shown to be economically viable, compared to continued gas or oil-firing. The Computed IRR's are all far in excess of projected average interest rates for long term borrowings: approximately 15% for guarantee backed loans or as high as 20% for conventional financing. IRR is computed based on the total investment (equity plus debt) and cash flows before financing costs, i.e., before interest expense, but after the tax benefit of the interest deduction. The base case application for the Friendship analysis is case B/20 yr-gas which produces an IRR of 28.5% and payback of 3.4 years. Even better returns could be realized in the cases of oil-avoidance and where greater use of geothermal energy can be made as shown in the other cases considered.

District space heating potential of low temperature hydrothermal geothermal resources in the southwestern United States. Technical report  

DOE Green Energy (OSTI)

A computer simulation model (GIRORA-Nonelectric) is developed to study the economics of district space heating using geothermal energy. GIRORA-Nonelectric is a discounted cashflow investment model which evaluates the financial return on investment for space heating. This model consists of two major submodels: the exploration for and development of a geothermal anomaly by a geothermal producer, and the purchase of geothermal fluid by a district heating unit. The primary output of the model is a calculated rate of return on investment earned by the geothermal producer. The results of the sensitivity analysis of the model subject to changes in physical and economic parameters are given in this report. Using the results of the economic analysis and technological screening criteria, all the low temperature geothermal sites in Southwestern United States are examined for economic viability for space heating application. The methodology adopted and the results are given.

Utah State Prison Space Heating with Geothermal Heat Third Semi-Annual Report for the Period January 1981 - July 1981  

DOE Green Energy (OSTI)

Facing certain cost overruns and lacking information about the long term productivity of the Crystal Hot Springs geothermal resource, costs of construction for the geothermal retrofit, and the method of disposal of geothermal waste water, the Energy Office embarked on a strategy that would enable the project participants to develop accurate cost information on the State Prison Space Heating Program through the completion of Task 5-Construction. The strategy called for: (1) Completion of the resource assessment to determine whether test well USP/TH-1 could be used as a production well. If well USP/TH-1 was found to have sufficient production capacity, money would not have to be expended on drilling another production well. (2) Evaluation of disposal alternatives and estimation of the cost of each alternative. There was no contingency in the original budget to provide for a reinjection disposal system. Cooperative agreement DE EC07-ET27027 indicated that if a disposal system requiring reinjection was selected for funding that task would be negotiated with DOE and the budget amended accordingly. (3) Completion of the preliminary engineering and design work. Included in this task was a thorough net present value cash flow analysis and an assessment of the technical feasibility of a system retrofit given the production characteristics of well USP/TH-1 . In addition, completion of the preliminary design would provide cost estimates for the construction and commissioning of the minimum security geothermal space heating system. With this information accurate costs for each task would be available, allowing the Energy Office to develop strategies to optimize the use of money in the existing budget to ensure completion of the program. Reported herein is a summary of the work towards the completion of these three objectives conducted during the period of January 1981 through June 1981.

Direct-flash-steam geothermal-power-plant assessment. Final report  

DOE Green Energy (OSTI)

The objective of the project was to analyze the capacity and availability factors of an operating direct flash geothermal power plant. The analysis was to include consideration of system and component specifications, operating procedures, maintenance history, malfunctions, and outage rate. The plant studied was the 75 MW(e) geothermal power plant at Cerro Prieto, Mexico, for the years 1973 to 1979. To describe and assess the plant, the project staff reviewed documents, visited the plant, and met with staff of the operating utility. The high reliability and availability of the plant was documented and actions responsible for the good performance were identified and reported. The results are useful as guidance to US utilities considering use of hot water geothermal resources for power generation through a direct flash conversion cycle.

The Concession Agreement required TGC to perform geological, geophysical, and geochemical studies as part of the development program. TGC commenced the geotechnical studies in January 1996 with a comprehensive review of all existing data and surveys. Based on this review, TGC formulated an exploration plan and executed that plan commencing in April, 1996. The ground magnetic (GM), self potential (SP), magnetotelluric/controlled source audio magnetotelluric (MT/CSAMT) and one-meter temperature surveys, data integration, and synthesis of a hydrogeologic model were performed. The purpose of this report is to present a compilation of all data gathered from the geophysical exploration program and to provide an integrated interpretation of that data.

BACA Project: geothermal demonstration power plant. Final report  

DOE Green Energy (OSTI)

The various activities that have been conducted by Union in the Redondo Creek area while attempting to develop the resource for a 50 MW power plant are described. The results of the geologic work, drilling activities and reservoir studies are summarized. In addition, sections discussing the historical costs for Union's involvement with the project, production engineering (for anticipated surface equipment), and environmental work are included. Nineteen geothermal wells have been drilled in the Redondo Creek area of the Valles Caldera: a prominent geologic feature of the Jemez mountains consisting of Pliocene and Pleistocene age volcanics. The Redondo Creek area is within a complex longitudinal graben on the northwest flank of the resurgent structural dome of Redondo Peak and Redondo Border. The major graben faults, with associated fracturing, are geologically plausible candidates for permeable and productive zones in the reservoir. The distribution of such permeable zones is too erratic and the locations too imprecisely known to offer an attractive drilling target. Log analysis indicates there is a preferred mean fracture strike of N31W in the upper portion of Redondo Creek wells. This is approximately perpendicular to the major structure in the area, the northeast-striking Redondo Creek graben. The geothermal fluid found in the Redondo Creek reservoir is relatively benign with low brine concentrations and moderate H/sub 2/S concentrations. Geothermometer calculations indicate that the reservoir temperature generally lies between 500/sup 0/F and 600/sup 0/F, with near wellbore flashing occurring during the majority of the wells' production.

Geothermal reservoir well stimulation program. First-year progress report  

DOE Green Energy (OSTI)

The Geothermal Reservoir Well Stimulation Program (GRWSP) group planned and executed two field experiments at the Raft River KGRA during 1979. Well RRGP-4 was stimulated using a dendritic (Kiel) hydraulic fracture technique and Well RRGP-5 was stimulated using a conventional massive hydraulic fracture technique. Both experiments were technically successful; however, the post-stimulation productivity of the wells was disappointing. Even though the artificially induced fractures probably successfully connected with the natural fracture system, reservoir performance data suggest that productivity remained low due to the fundamentally limited flow capacity of the natural fractures in the affected region of the reservoir. Other accomplishments during the first year of the program may be summarized as follows: An assessment was made of current well stimulation technology upon which to base geothermal applications. Numerous reservoirs were evaluated as potential candidates for field experiments. A recommended list of candidates was developed which includes Raft River, East Mesa, Westmorland, Baca, Brawley, The Geysers and Roosevelt Hot Springs. Stimulation materials (fracture fluids, proppants, RA tracer chemicals, etc.) were screened for high temperature properties, and promising materials selected for further laboratory testing. Numerical models were developed to aid in predicting and evaluating stimulation experiments. (MHR)

Remote sensing for geothermal environmental assessments. Final report  

DOE Green Energy (OSTI)

The role of remote sensing is examined in the context of the DOE Environmental Assessment Studies. Particular attention has been paid to the exploitation, by computer analysis, of low altitude aerial photographs, which had been made available for this project. One technique, change detection - developed during this project - has been found to be particularly useful, because it permits to detect environmental changes at a very early stage where it might escape detection on the ground. This technique, which has now been perfected to be usable on a routine basis, can thus provide a very effective environmental early warning capability. Several examples are shown in known Geothermal Resource Areas (KGRA's) in the Imperial Valley and the Geysers, California, which lead to the conclusion that remote sensing should become an essential tool for the Environmental Assessment Studies.

Development of seals for a geothermal downhole intensifier. Progress report  

DOE Green Energy (OSTI)

A system using high-velocity fluid jets in conjunction with a rotary diamond bit is currently considered as the best candidate for reducing the cost of drilling geothermal wells. Technical, safety and cost considerations indicate that the required jet supply pressure can best be established by a downhole pressure intensifier. Key intensifier components are the check valve and plunger seals, which must prevent leakage of the high-pressure, high-temperature abrasive fluid (drilling mud). To achieve the required performance, novel ceramic seals are currently being developed. The check valve seal includes a tapered polymeric plug and ceramic stop acting against a ceramic seat. The ceramic plunger seal is a variant of the ''stepped-joint'' piston ring and is designed to minimize contact pressure and abrasive wear. Initial testing of these seals in the laboratory shows encouraging results; design refinement and further testing is in progress. 2 refs., 6 figs., 3 tabs.

Total Energy Recovery System for Agribusiness. [Geothermally heated]. Final Report  

DOE Green Energy (OSTI)

An engineering and economic study was made to determine a practical balance of selected agribusiness subsystems resulting in realistic estimated produce yields for a geothermally heated system known as the Total Energy Recovery System for Agribusiness. The subsystem cycles for an average application at an unspecified hydrothermal resources site in the western United States utilize waste and by-products from their companion cycles insofar as practicable. Based on conservative estimates of current controlled environment yields, produce wholesale market prices, production costs, and capital investment required, it appears that the family-operation-sized TERSA module presents the potential for marginal recovery of all capital investment costs. In addition to family- or small-cooperative-farming groups, TERSA has potential users in food-oriented corporations and large-cooperative-agribusiness operations. The following topics are considered in detail: greenhouse tomatoes and cucumbers; fish farming; mushroom culture; biogas generation; integration methodology; hydrothermal fluids and heat exchanger selection; and the system. 133 references.

Report of the workshop on advanced geothermal drilling and completion systems  

DOE Green Energy (OSTI)

The discussions, conclusions, and recommendations of the Workshop on Advanced Geothermal Drilling and Completion Systems are summarized. The purpose of the workshop was to identify new drilling and completion systems that have the potential for significantly reducing the cost of geothermal wells, and to provide recommendations as to the research and development tasks that are required to develop these advanced systems. Participants in the workshop included representatives from private industry, universities, and government who were organized into four working groups as follows: Rock Drilling Technology, Surface Technology, Borehole Technology, and Directional Drilling Technology. The Panel on Rock Drilling Technology was charged with identifying advanced concepts for breaking rock that could result in instantaneous penetration rates three to five times higher than those of conventional rotary drilling. The Panel on Surface Technology discussed improvements in surface equipment and operating procedures that could contribute to reduced well costs. The Panel on Borehole Technology discussed problems associated with establishing and maintaining a stable borehole for the long-term production of geothermal wells. The Panel on Directional Drilling Technology addressed problems encountered in drilling deviated wells in geothermal reservoirs.

Hot dry rock geothermal energy. Draft final report  

DOE Green Energy (OSTI)

This second EPRI workshop on hot dry rock (HDR) geothermal energy, held in May 1994, focused on the status of worldwide HDR research and development and used that status review as the starting point for discussions of what could and should be done next: by U.S. federal government, by U.S. industry, by U.S. state governments, and by international organizations or through international agreements. The papers presented and the discussion that took place indicate that there is a community of researchers and industrial partners that could join forces, with government support, to begin a new effort on hot dry rock geothermal development. This new heat mining effort would start with site selection and confirmatory studies, done concurrently. The confirmatory studies would test past evaluations against the most current results (from the U.S. site at Fenton Hill, New Mexico, and from the two sites in Japan, the one in Russia, and the two in western Europe) and the best models of relevant physical and economic aspects. Site selection would be done in the light of the confirmatory studies and would be influenced by the need to find a site where success is probable and which is representative enough of other sites so that its success would imply good prospects for success at numerous other sites. The test of success would be circulation between a pair of wells, or more wells, in a way that confirmed, with the help of flow modeling, that a multi-well system would yield temperatures, flows and lifetimes that support economically feasible power generation. The flow modeling would have to have previously achieved its own confirmation from relevant data taken from both heat mining and conventional hydrothermal geothermal experience. There may be very relevant experience from the enhancement of ''hot wet rock'' sites, i.e., sites where hydrothermal reservoirs lack, or have come to lack, enough natural water or steam and are helped by water injected cold and produced hot. The new site would have to be selected in parallel with the confirmatory studies because it would have to be modeled as part of the studies and because its similarity to other candidate sites must be known well enough to assure that results at the selected site are relevant to many others. Also, the industry partners in the joint effort at the new site must be part of the confirmatory studies, because they must be convinced of the economic feasibility. This meeting may have brought together the core of people who can make such a joint effort take place. EPRI sponsored the organization of this meeting in order to provide utilities with an update on the prospects for power generation via heat mining. Although the emerging rules for electric utilities competing in power generation make it very unlikely that the rate-payers of any one utility (or small group of utilities) can pay the differential to support this new heat mining research and development effort, the community represented at this meeting may be able to make the case for national or international support of a new heat mining effort, based on the potential size and economics of this resource as a benefit for the nation as a whole and as a contribution to reduced emissions of fossil CO{sub 2} worldwide.

DOE Green Energy (OSTI)

The work performed from August 1977 through January 1978 pertinent to the design of the Heber Geothermal Demonstration Power Plant is summarized. The report discusses review of earlier baseline geothermal studies performed by Holt/Procon and the design optimization performed by Fluor Engineers and Constructors, Inc., and The Ben Holt Company. The Heber project objective is to design, construct and operate a power plant to produce a net power output of 45 MW/sub e/, deriving energy from a low-salinity, moderate temperature (360/sup 0/F, 182/sup 0/C) brine heat source available from the Heber geothermal reservoir. A binary cycle conversion system employs a light aliphatic hydrocarbon mixture to derive heat from the brine supply, throuh heat exchangers, and drive the turbine-generator to produce power. Chevron Resources Company develops the geothermal resource for sale to San Diego Gas and Electric Company. Power output will be distributed to California's Imperial Valley by the Imperial Valley Irrigation District.

Technical-assistance report on a geothermal heating utility for Lemmon, South Dakota  

DOE Green Energy (OSTI)

The purpose of this effort was to review work already done toward establishing a geothermal heating utility in Lemmon, South Dakota; to redefine the goals for such a project; and to recommend how the project might proceeed to completion. The minimum size Phase I suggested would provide heat for up to 62 buildings in a 9-block area. Total cost is estimated at $1,800,000 to 1,950,000. The geothermal source is expected to be 100 to 400 gpm of 160/sup 0/F water pumped from 500 feet deep. Proposed energy savings and energy cost savings are presented. Analysis indicates that the major geothermal development effort in Lemmon should be directed toward the Madison aquifer. The minimum project dictates simple reinjection of the water after primary thermal extraction, although other uses are attractive and may be promoted if this resource is developed. A wide range of funding sources was investigated. Most promising avenues appear to be some form of local bond financing, and loans from the Farmer's Home Administration or the HUD Urban Development action grant program. The report suggests that a municipally-owned geothermal district heating utility be established, and a bond issue approved to pay for the initial well drilling, which is the major risk in the whole venture. A UDAG grant for 25% of the well cost may be obtainable. If the well proves successful, then the rest of the project can go forward.

Reservoir simulation studies: Wairakei Geothermal Field, New Zealand. Final report  

DOE Green Energy (OSTI)

Numerical reservoir simulation techniques were used to perform a history-match of the Wairakei geothermal system in New Zealand. First, a one-dimensional (vertical) model was chosen; realistic stratigraphy was incorporated and the known production history was imposed. The effects of surface and deep recharge were included. Good matches were obtained, both for the reservoir pressure decline history and changes in average discharge enthalpy with time. Next, multidimensional effects were incorporated by treating with a two-dimensional vertical section. Again, good history matches were obtained, although computed late-time discharge enthalpies were slightly high. It is believed that this disparity arises from inherently three-dimensional effects. Predictive calculations using the two-dimensional model suggest that continued future production will cause little additional reservoir pressure drop, but that thermal degradation will occur. Finally, ground subsidence data at Wairakei was examined. It was concluded that traditional elastic pore-collapse models based on classical soil-mechanics concepts are inadequate to explain the observed surface deformation. It is speculated that the measured subsidence may be due to structural effects such as aseismic slippage of a buried reservoir boundary fault.

Localized corrosion in materials for geothermal power. Final report  

DOE Green Energy (OSTI)

The influence of 16 different geothermally related environments on a number of potentially useful steels was examined for both general and localized corrosion and at ambient and 150/sup 0/C. Variation in chloride concentration of 1 to 20% generally demonstrated only minor aggressiveness in acidified solutions. In general, the presence of H/sub 2/S raised the corrosion rate. However, very low concentrations (10 ppM) indicated higher rates than in saturated brines. This is rationalized on the basis of the inability to develop a semi-protective film at the low H/sub 2/S concentration. The corrosion rate for the Cr-Mo steel was unexpectedly high at ambient, but improved substantially at 150/sup 0/C. The Ni-Cu-Nb steel consistently demonstrated excellent resistance in all environments, except the 10 ppM H/sub 2/S at ambient. At 150/sup 0/C there were no exceptions to its superior performance. Maximum pit depth studies, analyzed statistically, indicated that the Ni-Cu-Nb alloy was the most resistant to localized attack. A clean (low inclusions) Mn-C and a clean vacuum melted steel ranked well. A comparison of two almost identical Mn-C steels one clean and one dirty clearly indicated the deleterious influence of inclusions on the tendency for localized corrosion. The profiling of a protected section of a creviced or pitted sample helped to delineate the nebulous line of demarcation between general and localized corrosion in these low alloy steels.

Wind energy/geothermic/solar heating system. Final report  

SciTech Connect

I've observed three distinct ''camps'' of renewable energy resources; WIND, Geothermic, and Solar. None of the three are completely adequate for the NE by themselves. I observe little effort to combine them to date. My objective has been to demonstrate that the three can be combined in a practical system. To mitagate the high cost and poor payback for individual residences, I believe neighborhoods of 4 to 5 homes, apartment complexes or condominiums could form an Energy Association alloting a piece of ground (could be a greenbelt) which would contain the well or wells, solar boosted underground water storage and the Solar banks. These are the high cost items which could be prorated and ammortized by the Association. Easements would permit each residence underground insulated water lines for individual heat pump conversions to existing forced air furnaces. Where regulations permit, an individual home could erect his own windmill to belt drive his freon compressor. With or without the optional windmill the water to freon heat pump with its solar boosts on the well water, will enjoy COP's (coefficient of Performances or times better than electric resistance heat) beyond anything on the market today. In a neighborhood energy association, all trenching could be done together all plumbing could be one contract and they could qualify for quantity discounts on heat pump units, chillers and components and installation.

[Geothermal system temperature-depth database and model for data analysis]. 4. quarterly technical progress report  

DOE Green Energy (OSTI)

The activities that have been carried out this quarter include continued planning and development of the geothermal system thermal-well data-base that will be one of the main contract results. The authors are continuing to modify the specifications of the database and continuing initial input. They have added several additional areas to their inventory of the geothermal areas for which data are available in the literature (published and open file) and on open file as described in the third quarterly report. A map was enclosed with the second quarterly report that gave the preliminary location of sites of various categories of wells. They will include a revised map with the next quarterly report when all of the sites, including the new ones described below, have been located and added to the index map. In particular in the last quarter the authors have added about 100 wells in west Texas in the transPecos region from a previously proprietary report that they recently obtained. In addition they have made arrangements to obtain thermal data collected by AMAX Geothermal during their exploration activities. The number of wells is large, several hundred, and the sites are spread throughout the western US from New Mexico and Colorado to California and Oregon.

Geothermal Reservoir Engineering Research. Fourth annual report, October 1, 1983-September 30, 1984  

DOE Green Energy (OSTI)

Reservoir definition research consisted of well test analysis and bench-scale experiments. Well testing included both single-well pressure drawdown and buildup testing, and multiple-well interference testing. The development of new well testing methods continued to receive major emphasis during the year. Work included a project on multiphase compressibility, including the thermal content of the rock. Several projects on double-porosity systems were completed, and work was done on relative-permeability. Heat extraction from rock will determine the long-term response of geothermal reservoirs to development. The work in this task area involved a combination of physical and mathematical modeling of heat extraction from fractured geothermal reservoirs. International cooperative research dealt with adsorption of water on reservoir cores, the planning of tracer surveys, and an injection and tracer test in the Los Azufres fields. 32 refs.

West Texas geothermal resource assessment. Part II. Preliminary utilization assessment of the Trans-Pecos geothermal resource. Final report  

DOE Green Energy (OSTI)

The utilization potential of geothermal resources in Trans-Pecos, Texas was assessed. The potential for both direct use and electric power generation were examined. As with the resource assessment work, the focus was on the Hueco Tanks area in northeastern El Paso County and the Presidio Bolson area in Presidio County. Suitable users of the Hueco Tanks and Presidio Bolson resource areas were identified by matching postulated temperature characteristics of the geothermal resource to the need characteristics of existing users in each resource area. The amount of geothermal energy required and the amount of fossil fuel that geothermal energy would replace were calculated for each of the users identified as suitable. Current data indicate that temperatures in the Hueco Tanks resource area are not high enough for electric power generation, but in at least part of the Presidio Bolson resource area, they may be high enough for electric power generation.

Geothermal elastomeric materials. Twelve-months progress report, October 1, 1976--September 30, 1977  

DOE Green Energy (OSTI)

Progress is reported on efforts to develop elastomers for packer seal element applications which will survive downhole geothermal well chemistry at 260/sup 0/C (500/sup 0/F) for 24 hours. To achieve this development, a three level elastomer testing and evaluation program was established. The first level Screening Tests is a broad screening of potential candidates and with the end objective to filter out the more promising candidates for more expensive subsequent testing. The battery of tests include standard ASTM tests and a special test developed to test extrusion resistance using specimens all made from sheet stock. The second level or Simulation Tests provide a laboratory equivalent of downhole conditions using synthetic geothermal fluid. Full scale packer seals are tested under simulated operational conditions by a test fixture. The third level or In-Situ Tests which are currently in the planning, provide for testing the most favored materials in-situ in the geothermal well. A test module provides for testing of the specimen without interfacing with the well casing. A test module freely hanging on a wireline has much lower probability of causing a problem, such as becoming lodged in the well, as compared to an operational casing packer. This maximizes the number of wells (hence geothermal environments) where access can be gained and In-Situ Testing performed. During this period commercially available polymers were investigated. Most of the work centered around formulating peroxide cured Vitons and some on EPDMs, butyls, and resin cured Vitons. Of the formulations tested to date the EPDMs appear most promising and the peroxide cured Vitons next most promising. However, data is too sparse to make any firm conclusions at this time. Minor tasks were performed evaluating current commercially available elastomers used in oil tools and conceptualization of casing packer for the geothermal application.

Geothermal direct-contact heat exchange. Final report  

DOE Green Energy (OSTI)

A glass direct contact heat exchange column was operated in the laboratory at atmospheric pressure using hot water and normal hexane. Column internals tested included an empty column, sieve trays, disk-and-doughnut trays, and two types of packing. Operation was very smooth in all cases and the minimum temperature approaches varied from less than 1{sup 0}C for packing to 13{sup 0}C for the empty column. High heat transfer rates were obtained in all cases, however, columns should be sized on the basis of liquid and vapor traffic. The solubilities of hydrocarbons were determined for normal hexane, pentane and butane in water and sodium chloride and calcium chloride brines at various temperatures. The values seem to be internally consistent and salt content was found to depress hydrocabon solubility. Laboratory stripping tests showed that gas stripping can be used to remove hydrocarbon from reject hot water from the direct contact heat exchange column. Although the gas volumes required are small, stripping gas requirements cannot be accurately predicted without testing. A computer program was used to study the effect of operating variables on thermodynamic cycle efficiencies. Optimum efficiencies for the moderate brine conditions studied were obtained with isopentane as working fluid and relatively low operating pressure. A preliminary design for a 50 MWe plant was prepared and plant capital cost and operating cost were estimated. These costs were combined with previously developed brine production and power transmission costs to provide an estimate of the cost of delivered power for a geothermal field at Heber, California. A pilot plant program is described that would be suitable for continuing the investigation of the direct contact process in the field. The program includes a suggested schedule and the estimated cost.

Modeling, design, and life performance prediction for energy production from geothermal reservoirs. Final report  

DOE Green Energy (OSTI)

System modeling supports the design and long-term, commercially successful operation of geothermal reservoirs. Modeling guides in the placement of the injection and production wells, in the stimulation of the reservoir, and in the operational strategies used to ensure continuing production. Without an understanding of the reservoir, it is possible to harm the reservoir by inappropriate operation (especially break-through of cold injection fluid) and the desired profitable lifetimes will not be reached. In this project the authors have continued to develop models for predicting the life of geothermal reservoirs. One of the goals has been to maintain and transfer existing Hot Dry Rock two-dimensional fractured reservoir analysis capability to the geothermal industry and to begin the extension of the analysis concepts to three dimensions. Primary focus has been on interaction with industry, maintenance of Geocrack2D, and development of the Geocrack3D model. It is important to emphasize that the modeling is complementary to current industry modeling, in that they focus on flow in fractured rock and on the coupled effect of thermal cooling. In the following sections the authors document activities as part of this research project: industry interaction; national and international collaboration; and model development.

SciTech Connect

This report describes the design, construction, and performance of the New Mexico State University (NMSU) Geothermal Greenhouse Research Facility. Two 6000-square-foot greenhouses were built on the NMSU campus and supplied with geothermal energy for heating. The geothermal water is pumped from one of three wells producing water at temperatures from 141/degree/F to 148/degree/F. Heat is delivered to the greenhouse space by means of overhead fan-coil unit heaters. The two greenhouses are double-glazed on roof and wall surfaces employing a total of four different film materials: Tedlar/Reg Sign/, Melinex/Reg Sign/, Softglass/Reg Sign/, and Agrifilm/Reg Sign/. One greenhouse is cooled using a traditional fan and pad cooling system. The second greenhouse is cooled with a high-pressure fog system and natural ventilation through roof and side vents. A 2400-square-foot metal building next to the greenhouses provides office, work, and storage space for the facility. The greenhouse facility was leased to two commerical tenants who produced a variety of crops. The performance of the greenhouses was monitored and reported both qualitatively and quantitatively. Results from the tenant's pilot-scale studies in the NMSU greenhouse facility were transferred and applied to two commercial greenhouse ranges that were built in southern New Mexico during 1986/87. 9 figs., 5 tabs.

Development of a geothermal resource in a fractured volcanic formation: Case study of the Sumikawa Geothermal Field, Japan. Final report, May 1, 1995--November 30, 1997  

DOE Green Energy (OSTI)

The principal purpose of this case study of the Sumikawa Geothermal Field is to document and to evaluate the use of drilling logs, surface and downhole geophysical measurements, chemical analyses and pressure transient data for the assessment of a high temperature volcanic geothermal field. This comprehensive report describes the work accomplished during FY 1993-1996. A brief review of the geological and geophysical surveys at the Sumikawa Geothermal Field is presented (Section 2). Chemical data, consisting of analyses of steam and water from Sumikawa wells, are described and interpreted to indicate compositions and temperatures of reservoir fluids (Section 3). The drilling information and downhole pressure, temperature and spinner surveys are used to determine feedzone locations, pressures and temperatures (Section 4). Available injection and production data from both slim holes and large-diameter wells are analyzed to evaluate injectivity/productivity indices and to investigate the variation of discharge rate with borehole diameter (Section 5). New interpretations of pressure transient data from several wells are discussed (Section 6). The available data have been synthesized to formulate a conceptual model for the Sumikawa Geothermal Field (Section 7).

Geothermal enhancement of mineral processing in Nevada: Final report, April 25, 1985-June 30, 1986  

SciTech Connect

This report reviews mineral recovery techniques practiced at active mines throughout Nevada and determines those that may be enhanced by the application of geothermal heat energy from a nearby resource. Of the thirty-two active precious metal mines identified, ten have hot water on or near the property and could potentially benefit. A second purpose was to collect ore samples and geothermal fluids, determine if they are compatible in the hydrometallurgical process, and carry out laboratory tests to determine the effects of heating on recovery rates. In addition, interfering or counterproductive factors were also identified. The laboratory work consisted of measuring the effects of thermally enhancing two hydrometallurgical processes; cyanide heap-leaching of gold and silver ores and bacterial leaching of sulfide rich gold ores. Thermally enhanced cyanide heap-leaching of gold and silver ores produced increases in extraction ranging from 8 to 20% for gold and 17 to 40% for silver. The temperature required for these increases is 35/sup 0/C to 40/sup 0/C, well within the range of available geothermal resources.

Geothermal space heating applications for the Fort Peck Indian Reservation in the vicinity of Poplar, Montana. Final report, August 20, 1979-May 31, 1980  

DOE Green Energy (OSTI)

The results of a first-stage evaluation of the overall feasibility of utilizing geothermal waters from the Madison aquifer in the vicinity of Poplar, Montana for space heating are reported. A preliminary assessment of the resource characteristics, a preliminary design and economic evaluation of a geothermal heating district and an analysis of environmental and institutional issues are included. Preliminary investigations were also made into possible additional uses of the geothermal resource, including ethanol production. The results of the resource analysis showed that the depth to the top of the Madison occurs at approximately 5,500 feet at Poplar, and the Madison Group is characterized by low average porosity (about 5 percent) and permeability (about 0.004 gal/day-ft), and by hot water production rates of a few tens of gallons per minute from intervals a few feet thick. The preliminary heating district system effort for the town of Poplar included design heat load estimates, a field development concept, and preliminary design of heat extraction and hot water distribution systems. The environmental analysis, based on current data, indicated that resource development is not expected to result in undue impacts. The institutional analysis concluded that a Tribal geothermal utility could be established, but no clear-cut procedure can be identified without a more comprehensive evaluation of legal and jurisdistional issues. The economic evaluation found that, if the current trend of rapidly increasing prices for fossil fuels continues, a geothermal heating district within Poplar could be a long-term, economically attractive alternative to current energy sources.

Annual report on the project to design and experimentally test an improved geothermal drill bit  

DOE Green Energy (OSTI)

Progress is reported in a research and development program to design, build, and test an improved geothermal drill bit. The major tasks of the Phase I effort are entitled: failure mechanisms of existing bits; new steels and new bearing design; and new seals and lubricants. It appears that a significant gain in drill-bit life can be attained by the use of higher-temperature steels which retain more hardness at temperatures above 260/sup 0/C (500/sup 0/F). Such steels are available, and two research bits of high-temperature steels were made and will shortly be tested in a laboratory-simulated full-scale geothermal drilling environment. Two control bits of the same design, but made with conventional drill bit steels, were also obtained for identical laboratory test runs, so that the performance of the research bits can be meaningfully assessed. Base-line properties of the steels, such as hardness and fracture toughness as functions of temperature, are being measured to further assess the value of the high-temperature steels selected for the research bits. A geothermal test vessel was designed and fabricated in which the full-scale drill bits will be tested. The vessel is capable of temperature to 427/sup 0/C (800/sup 0/F) and pressures to 35 MPa (5,000 psi). Seal and lubrication designs were studied, and the state of the art in high-temperature seals and lubricants was assessed. Some candidate seals and lubricants have been obtained for testing, and others are being procured. In addition, a seal test vessel has been designed and will soon be completed which can simulate the geothermal drilling environment in full-scale testing of seal and lubricant designs and materials.

Update and assessment of geothermal economic models, geothermal fluid flow and heat distribution models, and geothermal data bases  

SciTech Connect

Numerical simulation models and data bases that were developed for DOE as part of a number of geothermal programs have been assessed with respect to their overall stage of development and usefulness. This report combines three separate studies that focus attention upon: (1) economic models related to geothermal energy; (2) physical geothermal system models pertaining to thermal energy and the fluid medium; and (3) geothermal energy data bases. Computerized numerical models pertaining to the economics of extracting and utilizing geothermal energy have been summarized and catalogued with respect to their availability, utility and function. The 19 models that are discussed in detail were developed for use by geothermal operators, public utilities, and lending institutions who require a means to estimate the value of a given resource, total project costs, and the sensitivity of these values to specific variables. A number of the models are capable of economically assessing engineering aspects of geothermal projects. Computerized simulations of heat distribution and fluid flow have been assessed and are presented for ten models. Five of the models are identified as wellbore simulators and five are described as reservoir simulators. Each model is described in terms of its operational characteristics, input, output, and other pertinent attributes. Geothermal energy data bases are reviewed with respect to their current usefulness and availability. Summaries of eight data bases are provided in catalogue format, and an overall comparison of the elements of each data base is included.

Evaluation and targeting of geothermal energy resources in the southeastern United States. Progress report, July 1--September 30, 1977  

DOE Green Energy (OSTI)

The objective of this program is to develop and apply targeting procedures for the evaluation of low-temperature radiogenically-derived geothermal resources in the eastern United States utilizing geological, geochemical, and geophysical data. The near-term resource assessment for Region V (the states east of the Rocky Mountains, excluding Texas and Louisiana) places primary programmatic emphasis on the confirmation of radiogenic resources in the Atlantic Coastal Plain. This emphasis is based on the partial confirmation of the radiogenic model as described in this and previous reports from VPI and SU. Geothermal gradients known to date in the Atlantic Coastal Plain are consistent with those expected from a concealed radiogenic source. Our current work in the Piedmont appears to be confirming the linear relationship between heat flow and heat generation. This is important because it permits theoretical calculations of temperatures to be expected within the sediments of the Atlantic Coastal Plain, in the granitic rocks beneath the Coastal Plain, and in those exposed in the Piedmont. Sixteen holes suitable for excellent heat flow determinations have been drilled by VPI and SU and will be reported on as the holes reach thermal equilibrium and chemical analyses and heat determination of core samples are completed. Reconnaissance surface sampling of igneous rocks was carried out to define the variation in surface heat generation that might be expected. Collation of existing gravity and magnetic data available for the Atlantic Coastal Plain was completed and modeling of selected negative gravity anomalies has begun. Insight into restrictions on the vertical distribution of heat-producing elements is being obtained by consideration of restraints imposed by analyses of metamorphic mineral assemblages.

Internal Technical Report, Heat Exchanger Sizing for 20 MW Geothermal Power Plants at MX Sites  

DOE Green Energy (OSTI)

This report presents the details of the analyses used to size the heaters, steam condenser, and working fluid condenser for a proposed 20 MW geothermal power plant application at MX sites in the southwest. These units would use a mixture of hydrocarbons (90% isobutane--10% n-hexane) to extract energy from moderate temperature resources (resource temperatures of 365 F, 400 F, and 450 F were considered). The working fluid will be maintained at supercritical pressures in the heater units. Studies have shown that this cycle will provide a significant net power increase over standard dual boiling single fluid cycles currently in use, e.g., the Raft River 5 MW pilot plant.

Progress in work to implement the program plan for the development of improved high temperature cementing materials for geothermal wells is reported. Work on the first element of the program management plan (problem definition) was completed and a report issued. The materials development and property verification phases of the plan are in progress. Plans for the down-hole testing phase of the program are being formulated. The most promising high temperature polymer cement (PC) system identified to date consists of a cross-linked mixture of styrene, acrylonitrile, and acrylamide in conjunction with a sand-cement filler. A study is in progress to optimize the concentrations of the mix components with respect to properties. Work to determine the pumpability of the system is in progress. Samples of PC have been removed after exposure at The Geysers to dry steam at 460/sup 0/F (238/sup 0/C) for 2 yrs. Visual inspection of the specimens indicated little apparent deterioration. The appendix includes five reports from contributing researchers on the development of high temperature cementing materials for geothermal wells.

This report presents the details of new geophysical work for the Paso Robles geothermal area, California performed under terms of the second year contract, 1979-80 between the US Department of Energy (DOE) and the California Division of Mines and Geology (CDMG). The report contains two sections. The first section is to provide background for the reader and consists of a reprint from CDMG's first year report (1979-80) to DOE. It describes only the Paso Robles studies performed by CDMG in its first year effort. The second section provides new information developed by CDMG in its 1979-80 studies concerning the geophysical survey of the Paso Robles geothermal area. Included in the first section is some general background information concerning the geology and geothermal occurrences in the Southern Coast Ranges, as well as the more detailed information dealing with the Paso Robles area proper. The second section is concerned only with discussion and interpretation of results for two geophysical methods that have so far been used by CDMG in the area: the ground magnetic and gravity surveys. The CDMG studies of the Paso Robles area are not yet complete and additional studies using newly acquired resistivity equipment are planned for the near future, as are more complete surveys of existing wells and new studies of the geothermal aquifers present in the area. A final report to DOE on the Paso Robles area is planned following completion of those studies.

Study of practical cycles for geothermal power plants. Interim report, June 15, 1975-March 31, 1976  

DOE Green Energy (OSTI)

The preliminary analysis is described in a study of practical cycles for geothermal power plants. The analysis is based on three different brines whose temperatures and composition span the range that is of practical interest for power generation. Only two kinds of cycles were considered in the analysis - the steam turbine cycle and the binary cycle, in which energy from the geothermal fluid is transferred to a secondary working fluid in a closed Rankine cycle. The performance of several condidate working fluids has been investigated, and the most attracive binary cycles have been selected for the various resource conditions. The results show that if brine is utilized directly in the primary heat exchange process with the secondary working fluid, the binary cycle is potentially better in terms of resource utilization than a dual flash steam turbine cycle. However, if the brine is flashed to steam and the steam is used for the heat exchange process, the steam turbine cycle will produce more power per pound of brine flow. Preliminary turbine designs have been formulated for steam and also for the most promising working fluids in the secondary or binary cycle. For all cycle configurations at least 50 MW of electrical power can be generated by a single unit without exceeding mechanical design or manufacturing limitations even when the resource temperature is as low as 400/sup 0/F. Plant economics were not considered.

Work to implement the program plan for the development of improved high temperature cementing materials for geothermal wells is continuing. Experimental work has been completed at the Colorado School of Mines. Samples of ..beta..-dicalcium silicate-silica cement developed in this program have been submitted for additional evaluation. The initial screening portion of this work has identified several promising systems that will undergo more rigorous testing. Dynamic brine exposure testing of several systems has been initiated at the East Mesa Geothermal Test Facility. Testing at the Niland test site is scheduled to start soon. Property verification tests on cements produced in the materials development phase of the program were initiated at the Bureau of Standards. Preliminary data are available for five cements exposed for 176 h to water at a temperature of 195/sup 0/C. Three of the cements exhibited strength losses during the test. An aluminum hydroxide cement and a polymer cement showed slight increases in strength after the exposure. These and longer-term data will be utilized in the selection of a material for use in the remedial cementing of a hot dry rock well at the Los Alamos Scientific Laboratory.

Pleasant Bayou geopressured/geothermal testing project, Brazoria County, Texas. Final report  

DOE Green Energy (OSTI)

Phase II-B production testing of the Pleasant Bayou No. 2 well began September 22, 1982. The test plan was designed to evaluate the capabilities of the geopressured-geothermal reservoir during an extended flow period. Tests were conducted to determine reservoir areal extent; aquifer fluid properties; fluid property change with production; information on reservoir production drive mechanism; long-term scale and corrosion control methods; and disposal well operations. Operatinal aspects of geopressured-geothermal production were also evaluated. The test was discontinued prematurely in May 1983 because of a production tubing failure. Most of the production tubing was recovered from the well and cause of the failure was determined. Plans for recompletion of the well were prepared. However, the well was not recompleted because of funding constraints and/or program rescheduling. In March 1984, the Department of Energy, Nevada Operations Office (DOE/NV) directed that the site be placed in a standby-secured condition. In August 1984, the site was secured. Routine site maintenance and security was provided during the secured period.

Hot dry rock geothermal energy for U.S. electric utilities. Draft final report  

DOE Green Energy (OSTI)

In order to bring an electric utility component into the study of hot dry rock geothermal energy called for in the Energy Policy Act of 1992 (EPAct), EPRI organized a one-day conference in Philadelphia on January 14,1993. The conference was planned as the first day of a two-day sequence, by coordinating with the U.S. Geological Survey (USGS) and the U.S. Department of Energy (DOE). These two federal agencies were charged under EPAct with the development of a report on the potential for hot dry rock geothermal energy production in the US, especially the eastern US. The USGS was given lead responsibility for a report to be done in association with DOE. The EPRI conference emphasized first the status of technology development and testing in the U.S. and abroad, i.e., in western Europe, Russia and Japan. The conference went on to address the extent of knowledge regarding the resource base in the US, especially in the eastern half of the country, and then to address some practical business aspects of organizing projects or industries that could bring these resources into use, either for thermal applications or for electric power generation.

City of North Bonneville, Washington: Geothermal Exploration Project, production test well, Phase II. Final report  

SciTech Connect

Based on discussions with the City of North Bonneville, the production test well was drilled to a depth that would also explore for ground water temperatures near 130/sup 0/F (54.4/sup 0/C). Depth projections to a 130/sup 0/F bottom hole temperature were made by assuming a constant ground water temperature rise greater than 50/sup 0/C per kilometer, and by assuming that essentially homogeneous or equivalent conductive rock units would be encountered. Minimum water production requirements were not set, although the City determined that about 800 gpm would be acceptable. Large upper casing diameters of 16 and 12 inches were installed in order to provide the future use of either a vertical turbine or submersible pump, as desired by the city. The scope of work included interpretation of well characteristics, evaluation of ground water as a geothermal resource, geologic analysis of data from drilling and testing, drilling supervision, daily drilling cost accounting, and preparation of a final report. The report includes geologic evaluation of the drilling and test data, ground water and geothermal potential.

Planning and design of additional East Mesa Geothermal Test Facilities. Phase 1B. Volume I. Final report  

DOE Green Energy (OSTI)

The planning and design of additions to the ERDA East Mesa Geothermal Component Test Facility are discussed. The ERDA East Mesa Geothermal Component Test Facility will provide moderate temperature/low salinity fluids to facilitate comprehensive testing of conversion systems and components under realistic field conditions. The project objectives included development of designs of new wells and modifications to existing wells to improve definitive reservoir evaluations and design of additional test facilities integrated with the limited-scale facilities to accommodate diverse commercial utilization technology experiments. A reservoir utilization evaluation was conducted to establish locations and design drilling programs for three new wells and modifications to existing wells to improve reservoir definition and provide a comprehensive inventory of geothermal well fluids for testing. Ten test facility additions were developed as individual procurement packages of specifications and drawings to facilitate near term construction activation.

Upstream H/sub 2/S removal from geothermal steam. Final report  

DOE Green Energy (OSTI)

The purpose of this project was to evaluate a new heat exchanger process as a method for removing hydrogen sulfide (H/sub 2/S) gas from geothermal steam upstream of a power plant turbine. The process utilizes a heat exchanger to condense geothermal steam so that noncondensable gases (including H/sub 2/S) can be removed in the form of a concentrated vent stream. Ultimate disposal of the removed H/sub 2/S gas may then be accomplished by use of other processes such as the commercially available Stretford process. The clean condensate is reevaporated on the other side of the heat exchanger using the heat removed from the condensing geothermal steam. The necessary heat transfer is induced by maintaining a slight pressure difference, and consequently a slight temperature difference, between the two sides of the heat exchanger. Evaluation of this condensing and reboiling process was performed primarily through the testing of a small-scale 14 m/sup 2/ (150 ft/sup 2/) vertical tube evaporator heat exchanger at The Geysers Power Plant in northern California. The field test results demonstrated H/sub 2/S removal rates consistently better than 90 percent, with an average removal rate of 94 percent. In addition, the removal rate for all noncondensable gases is about 98 percent. Heat transfer rates were high enough to indicate acceptable economics for application of the process on a commercial scale. The report also includes an evaluation of the cost and performance of various configurations of the system, and presents design and cost estimates for a 2.5 MWe and a 55 MWe unit.

Workplan for FY1978 to FY1982 including a computerized reporting and monitoring system for geothermal energy development  

DOE Green Energy (OSTI)

It is proposed that the on-going compilation and critical evaluation of data be expanded to include a computerized system for monitoring and reporting the development of geothermal resources from the discovery phase to power on-line. Data would be covered which is site-specific and therefore unique to the geothermal area. Computer printouts are to contain a listing of each geothermal site which will be classified according to the status of development for producing electrical power. The result of the work will consist of a report containing a description of the data at each site and recommendaions for additional data needs in technological, economic, or institutional areas. The computerized system will allow for ease in updating and remote accessing by off-site users.

Geothermal heating retrofit at the Utah State Prison Minimum Security Facility. Final report, March 1979-January 1986  

DOE Green Energy (OSTI)

This report is a summary of progress and results of the Utah State Prison Geothermal Space Heating Project. Initiated in 1978 by the Utah State Energy Office and developed with assistance from DOE's Division of Geothermal and Hydropower Technologies PON program, final construction was completed in 1984. The completed system provides space and water heating for the State Prison's Minimum Security Facility. It consists of an artesian flowing geothermal well, plate heat exchangers, and underground distribution pipeline that connects to the existing hydronic heating system in the State Prison's Minimum Security Facility. Geothermal water disposal consists of a gravity drain line carrying spent geothermal water to a cooling pond which discharges into the Jordan River, approximately one mile from the well site. The system has been in operation for two years with mixed results. Continuing operation and maintenance problems have reduced the expected seasonal operation from 9 months per year to 3 months. Problems with the Minimum Security heating system have reduced the expected energy contribution by approximately 60%. To date the system has saved the prison approximately $18,060. The total expenditure including resource assessment and development, design, construction, performance verification, and reporting is approximately $827,558.

Advancing Reactive Tracer Methods for Measurement of Thermal Evolution in Geothermal Reservoirs: Final Report  

DOE Green Energy (OSTI)

The injection of cold fluids into engineered geothermal system (EGS) and conventional geothermal reservoirs may be done to help extract heat from the subsurface or to maintain pressures within the reservoir (e.g., Rose et al., 2001). As these injected fluids move along fractures, they acquire heat from the rock matrix and remove it from the reservoir as they are extracted to the surface. A consequence of such injection is the migration of a cold-fluid front through the reservoir (Figure 1) that could eventually reach the production well and result in the lowering of the temperature of the produced fluids (thermal breakthrough). Efficient operation of an EGS as well as conventional geothermal systems involving cold-fluid injection requires accurate and timely information about thermal depletion of the reservoir in response to operation. In particular, accurate predictions of the time to thermal breakthrough and subsequent rate of thermal drawdown are necessary for reservoir management, design of fracture stimulation and well drilling programs, and forecasting of economic return. A potential method for estimating migration of a cold front between an injection well and a production well is through application of reactive tracer tests, using chemical whose rate of degradation is dependent on the reservoir temperature between the two wells (e.g., Robinson 1985). With repeated tests, the rate of migration of the thermal front can be determined, and the time to thermal breakthrough calculated. While the basic theory behind the concept of thermal tracers has been understood for some time, effective application of the method has yet to be demonstrated. This report describes results of a study that used several methods to investigate application of reactive tracers to monitoring the thermal evolution of a geothermal reservoir. These methods included (1) mathematical investigation of the sensitivity of known and hypothetical reactive tracers, (2) laboratory testing of novel tracers that would improve method sensitivity, (3) development of a software tool for design and interpretation of reactive tracer tests and (4) field testing of the reactive tracer temperature monitoring concept.

Community Geothermal Technology Program: Media steam pasteurization using geothermal fluid at NELHA, Noi`i O Puna laboratory; Final report  

DOE Green Energy (OSTI)

The project was successful in confirming the suitability of shredded coconut husks in potting mix and the acceptability of untreated geothermal steam to pasteurize the mix. The pots were exposed to the steam; the average media temperature was maintained at 160 F for 30 min. The pH levels, which were slightly elevated in virgin media, rose only slightly (< 0.5) after steaming. Salt levels doubled (still safe). Mg solubility increased but not to toxic levels. Test plantings showed no significant differences after 8 months, indicating that coconut fiber can be pasteurized and used to replace imported peat moss. 6 refs, 4 tabs.

Direct utilization of geothermal heat in cascade application to aquaculture and greenhouse systems at Navarro College. Final report, March 1, 1979-September 30, 1984  

DOE Green Energy (OSTI)

This final report documents the Navarro College geothermal use project, which is one of nineteen direct-use geothermal projects funded principally by DOE. The six-year project encompassed a broad range of technical, institutional, and economic activities including: resource and environmental assessment; well drilling and completion; system design, construction, and monitoring; economic analysis; and public awareness programs. Some of the project conclusions are that: (1) the 130/sup 0/F Central Texas geothermal resource can support additional geothermal development; (2) private sector economic incentives currently exist which encourage commercial development of this geothermal resource; (3) potential uses for this geothermal resource include water and space heating, aquacultural and agricultural heating uses, and fruit and vegetable dehydration; (4) high maintenance costs arising from the geofluids' scaling and corrosion characteristics can be avoided through proper analysis and design.

US Gulf Coast geopressured-geothermal reservoir simulation. Final report (Year 3)  

DOE Green Energy (OSTI)

Several reservoir model improvements incorporated into the UTA model are described. The most significant modification to the model was the inclusion of semiimplicit treatment of transmissibilities so as to better handle two-phase flow problems associated with flow near the wellbore. A description of the reservoir mechanics presumed operative in geopressured-geothermal reservoirs is included. A mathematical model describing two-dimensional flow in compacting porous media is developed from the Lagrangian point of view. A description of the way the differential equations are approximated by finite differences and subsequently solved by means of numerical procedures is presented. Various sensitivity studies made with the reservoir model are described. Particular emphasis was given to the study of potential shale dewatering effects on reservoir depletion and the effects of compaction on fluid recovery. To study shale dewatering, the shale thickness and the shale vertical permeability were treated as variables in several simulation experiments. The effects of compaction were modeled with optimistic and pessimistic values for the uniaxial compaction coefficient in an attempt to define a region of expected reservoir performance. Laboratory analysis of core samples obtained from the geopressured-geothermal test well was completed by the end of year 3. These data indicate that the uniaxial compaction coefficient is of the same order of magnitude as the pessimistic value used on the sensitivity studies. Because of this the expected fluid recovery from geopressured reservoirs has been reduced to a nominal 5% of the in-place volumes rather than the previously reported 10%.

Geothermal spas in Hawaii: A new tourist industry. : A preliminary report  

SciTech Connect

There are at least three very good uses for active volcanism: Obtain energy from it. Study it. Enjoy it. We are already obtaining electrical energy and industrial heat from Kilauea's abundant resource by drilling geothermal wells and building power plants. Our Volcano Observatory is recognized as a world renowned center of learning about volcanism. Our Volcanoes National Park allows us to view and appreciate this awesome phenomenon. For several years people have speculated about the high potential in Hawaii for another way of enjoying this warmth of mother earth -- spas or resorts that would make use of water that is naturally heated and mineralized by volcanic activity. However, before spas are developed in Hawaii, answers are needed to several important questions dealing with such topics as the suitability of our geothermal waters, sources of water that could be tapped, special equipment and materials needed, land availability, governmental and environmental hurdles, and the economics of this unique business. Though a considerable amount of research is still needed, it was felt worthwhile to summarize the information gathered to date from historical works, brochures, personal communications, and other sources. This report should stimulate interest in, and perhaps accelerate, the development of one of Hawaii's most important natural resources.

COATINGS FOR PROTECTION OF EQUIPMENT FOR BIOCHEMICAL PROCESSING OF GEOTHERMAL RESIDUES: PROGRESS REPORT FY 97  

DOE Green Energy (OSTI)

Thermal sprayed ethylene methacrylic acid (EMAA) and ethylene tetrafluoroethylene (ETFE), spray-and-bake ETFE and polyvinylidene fluoride (PVDF) and brushable ceramic-epoxy coatings were evaluated for corrosion protection in a biochemical process to treat geothermal residues. The findings are also relevant to other moderate temperature brine environments where corrosion is a problem. Coupon, Atlas cell, peel strength, cathodic disbondment and abrasion tests were performed in aggressive environments including geothermal sludge, hypersaline brine and sulfur-oxidizing bacteria (Thiobadus ferrooxidans) to determine suitability for protecting storage tanks and reaction vessels. It was found that all of the coatings were resistant to chemical attack and biodegradation at the test temperature of 55 C. The EMAA coatings protected 316L stainless steel from corrosion in coupon tests. However, corrosion of mild steel substrates thermal sprayed with EMAA and ETFE occurred in Atlas cell tests that simulated a lined reactor operating environment and this resulted in decreased adhesive strength. Peel tests to measure residual adhesion revealed that failure mode was dependent on exposure conditions. Long-term tests on the durability of ceramic-epoxy coatings in brine and bacteria are ongoing. Initial indications are that this coating has suitable characteristics. Abrasion tests showed that the ceramic-epoxy had good resistance to the abrasive effects of sludge. Thermal sprayed EMAA coatings also displayed abrasion resistance. Cathodic disbondment tests in brine at room temperature indicated that EMAA coatings are resistant to disbondment at applied potentials of {minus}780 to {minus}1,070 mV SCE for the test conditions and duration. Slight disbondment of one specimen occurred at a potential of {minus}1,500 mV SCE. The EMAA may be suited to use in conjunction with cathodic protection although further long-term, higher temperature testing would be needed.

The evaluation of a 4000-home geothermal heat pump retrofit at Fort Polk, Louisiana: Final Report  

SciTech Connect

This report documents an independent evaluation of an energy retrofit of 4,003 family housing units at Fort Polk, Louisiana, under an energy savings performance contract (ESPC). Replacement of the heating, cooling, and water heating systems in these housing units with geothermal heat pumps (GHPs) anchored the retrofit; low-flow shower heads and compact fluorescent lighting were also installed, as well as attic insulation where needed. Statistically valid findings indicate that the project will save 25.8 million kWh, or 32.5% of the pre-retrofit whole-community electrical consumption, and 100% of the whole-community natural gas previously used for space conditioning and water heating (260,000 therms) in a typical meteorological year. At the end-use level, the GHPs were found to save about 42% of the pre-retrofit electrical consumption for heating, cooling, and water heating in housing units that were all-electric in the pre-retrofit period. This report also demonstrates an improved method of predicting energy savings. Using an engineering model calibrated to pre-retrofit energy use data collected in the field, the method predicted actual energy savings on one of the electric feeders at Fort Polk with a very high degree of accuracy. The accuracy of this model was in turn dependent on data-calibrated models of the geothermal heat pump and ground heat exchanger that are described in this report. In addition this report documents the status of vertical borehole ground heat exchanger (BHEx) design methods at the time this project was designed, and demonstrates methods of using data collected from operating GHP systems to benchmark BHEx design methods against a detailed engineering model calibrated to date. The authors also discuss the ESPC`s structure and implementation and how the experience gained here can contribute to the success of future ESPCs.

Simulation of fluid-rock interactions in a geothermal basin. Final report. [QUAGMR (quasi-active geothermal reservoir)  

DOE Green Energy (OSTI)

General balance laws and constitutive relations are developed for convective hydrothermal geothermal reservoirs. A fully interacting rock-fluid system is considered; typical rock-fluid interactions involve momentum and energy transfer and the dependence of rock porosity and permeability upon the fluid and rock stresses. The mathematical model also includes multiphase (water/steam) effects. A simple analytical model is employed to study heat transfer into/or from a fluid moving in a porous medium. Numerical results show that for fluid velocities typical of geothermal systems (Reynolds number much less than 10), the fluid and the solid may be assumed to be in local thermal equilibrium. Mathematical formalism of Anderson and Jackson is utilized to derive a continuum species transport equation for flow in porous media; this method allows one to delineate, in a rigorous manner, the convective and diffusive mechanisms in the continuum representation of species transport. An existing computer program (QUAGMR) is applied to study upwelling of hot water from depth along a fault; the numerical results can be used to explain local temperature inversions occasionally observed in bore hole measurements.

Direct utilization of geothermal energy resources in food processing. Final report, May 17, 1978-May 31, 1982  

DOE Green Energy (OSTI)

In early 1978 financial assistance was granted for a project to utilize geothermal energy at Ore-Ida Foods, Inc.'s food processing plant in Ontario, Oregon. Specifically, the project included exploring, testing, and developing the potential geothermal resource; retrofitting the existing gas/oil-fired steam system; utilizing the geothermal resource for food processing, space heating, and hot potable water; and injecting the spent geothermal water back into a disposal well. Based on preliminary investigations which indicated the presence of a local geothermal resource, drilling began in August 1979. Although the anticipated resource temperature of 380/sup 0/F was reached at total well depth (10,054 feet), adequate flow to meet processing requirements could not be obtained. Subsequent well testing and stimulation techniques also failed to produce the necessary flow, and the project was eventually abandoned. However, throughout the duration of the project, all activities were carefully monitored and recorded to ensure the program's value for future evaluation. This report presents a culmination of data collected during the Ore-Ida project.

The methods are based on estimated thermal properties of the reservoir components, reservoir management planning of production and reinjection, and the mixing of reservoir fluids: geothermal, resource fluid cooled by drawdown and infiltrating groundwater, and reinjected recharge heated by sweep flow through the reservoir formation. Several reports and publications, listed in Appendix A, describe the development of the analytical methods which were part of five Engineer and PhD dissertations, and the results from many applications of the methods to achieve the project objectives. The Heat Extraction Project is to evaluate the thermal properties of fractured geothermal resource and forecasted effects of reinjection recharge into operating reservoirs.

Interim Report: Air-Cooled Condensers for Next Generation Geothermal Power Plants Improved Binary Cycle Performance  

DOE Green Energy (OSTI)

As geothermal resources that are more expensive to develop are utilized for power generation, there will be increased incentive to use more efficient power plants. This is expected to be the case with Enhanced Geothermal System (EGS) resources. These resources will likely require wells drilled to depths greater than encountered with hydrothermal resources, and will have the added costs for stimulation to create the subsurface reservoir. It is postulated that plants generating power from these resources will likely utilize the binary cycle technology where heat is rejected sensibly to the ambient. The consumptive use of a portion of the produced geothermal fluid for evaporative heat rejection in the conventional flash-steam conversion cycle is likely to preclude its use with EGS resources. This will be especially true in those areas where there is a high demand for finite supplies of water. Though they have no consumptive use of water, using air-cooling systems for heat rejection has disadvantages. These systems have higher capital costs, reduced power output (heat is rejected at the higher dry-bulb temperature), increased parasitics (fan power), and greater variability in power generation on both a diurnal and annual basis (larger variation in the dry-bulb temperature). This is an interim report for the task Air-Cooled Condensers in Next- Generation Conversion Systems. The work performed was specifically aimed at a plant that uses commercially available binary cycle technologies with an EGS resource. Concepts were evaluated that have the potential to increase performance, lower cost, or mitigate the adverse effects of off-design operation. The impact on both cost and performance were determined for the concepts considered, and the scenarios identified where a particular concept is best suited. Most, but not all, of the concepts evaluated are associated with the rejection of heat. This report specifically addresses three of the concepts evaluated: the use of recuperation, the use of turbine reheat, and the non-consumptive use of EGS make-up water to supplement heat rejection

Basin View Geothermal Heating District, Klamath Falls, Oregon: conceptual design and economic-feasibility study report  

DOE Green Energy (OSTI)

The findings of a feasibility study performed for Basin View Heating District in Klamath Falls, Oregon are reported. The purpose of the study is to determine the physical, economic, and political feasibility of establishing a geothermal heating district to provide space heat to housing units in the Basin View Development of Klamath Falls. Of the several systems considered, all are physically feasible. The project is politically feasible if the owner compiles with governmental requirements. Economic feasibility is based on considerations of money value rates, tax rates and expected rates of return, which are dependent on government and money markets. For analysis a money value rate of 21% and an owner's marginal tax rate of 35% were adopted.

Coatings for protection of equipment for biochemical processing of geothermal residues: Progress report FY`97  

DOE Green Energy (OSTI)

Thermal sprayed ethylene methacrylic acid (EMAA) and ethylene tetrafluoroethylene (ETFE), spray-and-bake ETFE and polyvinylidene fluoride (PVDF) and brushable ceramic-epoxy coatings were evaluated for corrosion protection in a biochemical process to treat geothermal residues. Coupon, Atlas cell, peel strength, cathodic disbondment and abrasion tests were performed in aggressive environments including geothermal sludge, hypersaline brine and sulfur-oxidizing bacteria (Thiobacillus ferrooxidans) to determine suitability for protecting storage tanks and reaction vessels. It was found that all of the coatings were resistant to chemical attack and biodegradation at the test temperature of 55 C. The EMAA coatings protected 316L stainless steel from corrosion in coupon tests. However, corrosion of mild steel substrates thermal sprayed with EMAA and ETFE occurred in Atlas cell tests that simulated a lined reactor operating environment and this resulted in decreased adhesive strength. Peel tests to measure residual adhesion revealed that failure mode was dependent on exposure conditions. Abrasion tests showed that the ceramic-epoxy had good resistance to the abrasive effects of sludge. Thermal sprayed EMAA coatings also displayed abrasion resistance. Cathodic disbondment tests in brine at room temperature indicated that EMAA coatings are resistant to disbondment at applied potentials of {minus}780 to {minus}1,070 mV SCE for the test conditions and duration. Slight disbondment of one specimen occurred at a potential of {minus}1,500 mV SCE. The EMAA may be suited to use in conjunction with cathodic protection although further long-term, higher temperature testing would be needed.

Use of geothermal heat for crop drying and related agricultural applications. Final report  

DOE Green Energy (OSTI)

Observations led to the selection of the alfalfa dehydration industry for in-depth analysis of the application of moderate-temperature geothermal heat. Six geothermal heat exchanger/dryer configurations were examined. A low-temperature conveyor dryer using geothermal water to supply all required heat was chosen for site-specific analysis, the retrofitting of a large alfalfa dehydration plant within the Heber KGRA in the Imperial Valley, California. Even in the most favorable scenario--sharing a geothermal pipeline with the neighboring fertilizer plant--geothermal retrofitting would increase the price of the alfalfa ''dehy'' about 40 percent. The geothermal brine is estimated to cost $2.58/million Btu's compared with a 1977 natural gas cost of $1.15. Capital cost for heat exchangers and the new dryers is estimated at $3.3 million. The Heber plant appeared to offer the only good opportunity for geothermal retrofitting of an existing alfalfa dehydration plant. Construction of new plants at geothermal resource sites cannot be justified due to the uncertain state of the ''dehy'' industry. Use of geothermal heat for drying other crops may be much more promising. The potato dehydration industry, which is concentrated in the geothermal-rich Snake River Valley of Idaho, appears to offer good potential for geothermal retrofitting; about 4.7 x 10{sup 12}Btu's are used annually by plants within 50 miles of resources. Drying together at the geothermal wellhead several crops that have interlocking processing seasons and drying-temperature requirements may be quite attractive. The best ''multicrop drying center'' site identified was at Power Ranch Wells, Arizona; 34 other sites were defined. Agricultural processing applications other than drying were investigated briefly.

Use of geothermal heat for sugar refining. Final report, October 1, 1976--May 31, 1977  

DOE Green Energy (OSTI)

The economic and technical feasibility of applying low grade geothermal heat (less than 300/sup 0/F) in the beet sugar refining industry for both new factory construction and retrofit conversion of existing factories was assessed. The representative Holly Sugar factory at Brawley, California, was utilized as a baseline primarily because of its centralized location with respect to the known and partially developed geothermal anomalies at Brawley, East Mesa, and Heber. Nominal values for the key parameters of the sugar refining process and typical values for the geothermal fluid parameters representative of geothermal resources in areas of existing or potential future sugar factories were defined, promising points of application were identified, and conceptual designs synthesized for introducing the geothermal heat into the process. The design approaches were then quantified with capital, operating and maintenance costs, and comparative economic evaluations were made with other fuels projected to 1995. In parallel with the detailed study of process conversion to geothermal heat, the existing pattern and potential growth of the sugar refining industry was assessed to estimate the potential market for new factory construction at suitable areas, as well as the potential for retrofit conversion of existing factories. The environmental impact of other geothermal application concepts was also assessed, and expected technological or industry/government policy changes which might affect the potential for conversion to geothermal heat were identified and evaluated. Emphasis was placed on achieving results that would stimulate commercial utilization of geothermal heat for beet sugar refining and related processes.

Geothermal development on federal lands: the impediments and potential solutions. Final report, September 6, 1977--January 13, 1978  

DOE Green Energy (OSTI)

It is concluded that the regulatory program devised by the Bureau of Land Management and the US Geological Survey to implement the Geothermal Steam Act of 1970 has been ineffective thus far in encouraging private enterprise to invest in and develop this resource. After seven years, there is still no commercial production or utilization of the geothermal resource underlying federal lands. There are a number of factors--such as the unknown character of the resource and the less-than-perfect technologies for utilizing it and disposing of the resulting wastes--which are retarding the growth of a geothermal industry. However, would-be developers point to the complexity of the federal geothermal leasing and post-leasing requirements as the major impediment, and, specifically, the repetitive environmental review procedures involved. A fundamental fault in the regulatory process is that there is no provision for identification of the resource before a lease is issued. Identification of its characteristics is mandatory before the use to be made of it can be determined, if indeed it is found to be adequate and economic for any use. A very large percentage of the exploratory holes drilled will be abandoned as non-productive of a usable resource, in which case there is no need for the long term commitment of a lease. A streamlined regulatory process was designed to overcome these and other problems. If adopted, it would provide for orderly development of the resource and adequately protect the public interest and the environment.

Alpine 1/Federal: Temperature gradients, geothermal potential, and geology. Final report, Part 2  

DOE Green Energy (OSTI)

The Alpine 1/Federal drilling project provided valuable new; information on the geology of the region. Except for drilling into Precambrian rocks, the objectives of the project were accomplished. sufficient temperature and heat-flow information were obtained to assess the near-term HDR geothermal potential of the eastern White Mountains region. Therefore, the primary mission of the project was successful. The HDR potential for near-term electrical power production is not economic. Potential for HDR direct-use space heating is marginal at best and should realistically be considered uneconomic. The Alpine 1/Federal hole should be deepened to Precambrian basement to provide definitive subsurface geological information for this region. Deeper drilling will determine Precambrian lithology and assess if older Paleozoic rock units are present. The hole may be deepened with a BQ drill string. Depth to Precambrian is likely to be between 800 and 2,000 feet below the current 4,505 feet total depth. The failure to reach Precambrian basement due to a previously unknown and unmapped major structural offset highlights the need for detailed surface geological mapping in this poorly understood region.
