    Oregon Institute of Technology (OIT) drilled a deep geothermal well on campus (to 5,300 feet deep) which produced 196°F resource as part of the 2008 OIT Congressionally Directed Project. OIT will construct a geothermal power plant (estimated at 1.75 MWe gross output). The plant would provide 50 to 75 percent of the electricity demand on campus. Technical support for construction and operations will be provided by OIT’s Geo-Heat Center. The power plant will be housed adjacent to the existing heat exchange building on the south east corner of campus near the existing geothermal production wells used for heating campus. Cooling water will be supplied from the nearby cold water wells to a cooling tower or air cooling may be used, depending upon the type of plant selected. Using the flow obtained from the deep well, not only can energy be generated from the power plant, but the “waste” water will also be used to supplement space heating on campus. A pipeline will be construction from the well to the heat exchanger building, and then a discharge line will be construction around the east and north side of campus for anticipated use of the “waste” water by facilities in an adjacent sustainable energy park. An injection well will need to be drilled to handle the flow, as the campus existing injection wells are limited in capacity.

    1995-09-01

    A number of current and prospective power plant concepts were investigated to evaluate their potential to serve as the basis of the next generation geothermal power plant (NGGPP). The NGGPP has been envisaged as a power plant that would be more cost competitive (than current geothermal power plants) with fossil fuel power plants, would efficiently use resources and mitigate the risk of reservoir under-performance, and minimize or eliminate emission of pollutants and consumption of surface and ground water. Power plant concepts were analyzed using resource characteristics at ten different geothermal sites located in the western United States. Concepts were developed into viable power plant processes, capital costs were estimated and levelized busbar costs determined. Thus, the study results should be considered as useful indicators of the commercial viability of the various power plants concepts that were investigated. Broadly, the different power plant concepts that were analyzed in this study fall into the following categories: commercial binary and flash plants, advanced binary plants, advanced flash plants, flash/binary hybrid plants, and fossil/geothed hybrid plants. Commercial binary plants were evaluated using commercial isobutane as a working fluid; both air-cooling and water-cooling were considered. Advanced binary concepts included cycles using synchronous turbine-generators, cycles with metastable expansion, and cycles utilizing mixtures as working fluids. Dual flash steam plants were used as the model for the commercial flash cycle. The following advanced flash concepts were examined: dual flash with rotary separator turbine, dual flash with steam reheater, dual flash with hot water turbine, and subatmospheric flash. Both dual flash and binary cycles were combined with other cycles to develop a number of hybrid cycles: dual flash binary bottoming cycle, dual flash backpressure turbine binary cycle, dual flash gas turbine cycle, and binary gas turbine

    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.

    1990-12-01

    The Philippines has a rich potential for geothermal energy development, according to the assessment of opportunities for U.S. private investment in the sector. Areas covered in detail are the Philippines' geothermal resources, the legal structure of the geothermal industry, conditions acting as stimuli to geothermal power generation, and interest in private geothermal investment. Major finding are as follows. (1) The Philippine geothermal power industry is the world's second largest. (2) Geothermal resources are owned by the Government of the Philippines and a complex legal structure governs their exploitation. (3) Since the Philippines is poor in most energy resources (e.g., coal, oil, and gas), use of geothermal energy is necessary. (4) Despite legal and structural obstacles, various foreign private enterprises are interested in participating in geothermal development. Two possible options for U.S. investors are presented: a joint venture with the National Oil Company, and negotiation of a service contract, either alone or with a Philippine partner, for a concession on land administered by the Office of Energy Affairs.

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

    SciTech Connect (OSTI)

    Daniel S. Wendt; Greg L. Mines

    2010-09-01

    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

    1981-01-01

    The development of the geopressure geothermal unconventional gas resource has been the object of a drilling and reservoir testing program. One aspect of the assessment has been to look at the geothermal component of the energy base as a source of power generation. The basic production unit for the resource has been estimated to be a well capable of producing fluid at a rate of 15,000 to 40,000 BPD at temperatures of 240 to 360/sup 0/F (.0276 to .0736 M/sup 3//sec at 338 to 455/sup 0/K). The spacing of these wells will be approximately 2 to 4 km for effective reservoir drainage. This limits the generation capacity, per well from 700 to 3000 kW per site. It is assumed that interconnecting pipelines to carry brine from each well to a central location and then return it to salt water disposal wells will be impractical. Single well power plants with electrical gathering systems are considered to be the probable mode of development. The thermodynamic envelope within which the plant must operate is defined by the linear cooling curve of the brine and the ambient air temperature. The low resource temperature calls for a Rankine cycle. A supercritical propane cycle was selected. The only component of the thermal power system subject to uncertainty is the brine/propane heater. At the present time a scale/corrosion pilot plant is being operated on a number of geopressure test wells to determine inexpensive scale and corrosion inhibitors that may be used to reduce fouling of the exchanger tubes.

    A thermo-economic model has been built and validated for prediction of project economics of Enhanced Geothermal Projects. The thermo-economic model calculates and iteratively optimizes the LCOE (levelized cost of electricity) for a prospective EGS (Enhanced Geothermal) site. It takes into account the local subsurface temperature gradient, the cost of drilling and reservoir creation, stimulation and power plant configuration. It calculates and optimizes the power plant configuration vs. well depth. Thus outputs from the model include optimal well depth and power plant configuration for the lowest LCOE. The main focus of this final report was to experimentally validate the thermodynamic properties that formed the basis of the thermo-economic model built in Phase 2, and thus build confidence that the predictions of the model could be used reliably for process downselection and preliminary design at a given set of geothermal (and/or waste heat) boundary conditions. The fluid and cycle downselected was based on a new proprietary fluid from a vendor in a supercritical ORC cycle at a resource condition of 200�C inlet temperature. The team devised and executed a series of experiments to prove the suitability of the new fluid in realistic ORC cycle conditions. Furthermore, the team performed a preliminary design study for a MW-scale turbo expander that would be used for a supercritical ORC cycle with this new fluid. The following summarizes the main findings in the investigative campaign that was undertaken: 1. Chemical compatibility of the new fluid with common seal/gasket/Oring materials was found to be problematic. Neoprene, Viton, and silicone materials were found to be incompatible, suffering chemical decomposition, swelling and/or compression set issues. Of the materials tested, only TEFLON was found to be compatible under actual ORC temperature and pressure conditions. 2. Thermal stability of the new fluid at 200�C and 40 bar was found to be acceptable after 399

    1985-01-01

    The first geothermal power-plant in Turkey, the Kizildere 20 MW geothermal power-plant, is being constructed near Denizli - Saraykoy by GIE, Italy. Start-up operations have already begun an it will be generating electricity by the beginning of 1984. The plant will supply part of the power demands of Southwestern Anatolia, especially in the city of Denizli. This power-plant will utilize the geothermal resources discovered by the MTA (Mineral Research Exploration Institute) near Kizildere - Saraykoy at the end of research conducted between 1968 and 1971. MTA has been conducting this research all over Turkey and recently a new geothermal system has bee found in Germencik - Aydin. In Kizildere there are 16 wells drilled by MTA. However six of them (KD 13, KD 15, KD 16, KD 6 and KD 7, KD 14, three as stand-by) will be utilized for electricity generation.

  19. Improving Vortex Generators to Enhance the Performance of Air-Cooled Condensers in a Geothermal Power Plant

    SciTech Connect (OSTI)

    Manohar S. Sohal

    2005-09-01

    This report summarizes work at the Idaho National Laboratory to develop strategies to enhance air-side heat transfer in geothermal air-cooled condensers such that it should not significantly increase pressure drop and parasitic fan pumping power. The work was sponsored by the U.S. Department of Energy, NEDO (New Energy and Industrial Technology Development Organization) of Japan, Yokohama National University, and the Indian Institute of Technology, Kanpur, India. A combined experimental and numerical investigation was performed to investigate heat transfer enhancement techniques that may be applicable to largescale air-cooled condensers such as those used in geothermal power applications. A transient heat transfer visualization and measurement technique was employed in order to obtain detailed distributions of local heat transfer coefficients on model fin surfaces. Pressure drop measurements were obtained for a variety of tube and winglet configurations using a single-channel flow apparatus that included four tube rows in a staggered array. Heat transfer and pressure drop measurements were also acquired in a separate multiple-tube row apparatus in the Single Blow Test Facility. In addition, a numerical modeling technique was developed to predict local and average heat transfer for these low-Reynolds number flows, with and without winglets. Representative experimental and numerical results were obtained that reveal quantitative details of local finsurface heat transfer in the vicinity of a circular tube with a single delta winglet pair downstream of the cylinder. Heat transfer and pressure-drop results were obtained for flow Reynolds numbers based on channel height and mean flow velocity ranging from 700 to 6500. The winglets were of triangular (delta) shape with a 1:2 or 1:3 height/length aspect ratio and a height equal to 90% of the channel height. Overall mean fin-surface heat transfer results indicate a significant level of heat transfer enhancement (in terms of

  7. Use of a Geothermal-Solar Hybrid Power Plant to Mitigate Declines in Geothermal Resource Productivity

    SciTech Connect (OSTI)

    Dan Wendt; Greg Mines

    2014-09-01

    Many, if not all, geothermal resources are subject to decreasing productivity manifested in the form of decreasing brine temperature, flow rate, or both during the life span of the associated power generation project. The impacts of resource productivity decline on power plant performance can be significant; a reduction in heat input to a power plant not only decreases the thermal energy available for conversion to electrical power, but also adversely impacts the power plant conversion efficiency. The reduction in power generation is directly correlated to a reduction in revenues from power sales. Further, projects with Power Purchase Agreement (PPA) contracts in place may be subject to significant economic penalties if power generation falls below the default level specified. A potential solution to restoring the performance of a power plant operating from a declining productivity geothermal resource involves the use of solar thermal energy to restore the thermal input to the geothermal power plant. There are numerous technical merits associated with a renewable geothermal-solar hybrid plant in which the two heat sources share a common power block. The geo-solar hybrid plant could provide a better match to typical electrical power demand profiles than a stand-alone geothermal plant. The hybrid plant could also eliminate the stand-alone concentrated solar power plant thermal storage requirement for operation during times of low or no solar insolation. This paper identifies hybrid plant configurations and economic conditions for which solar thermal retrofit of a geothermal power plant could improve project economics. The net present value of the concentrated solar thermal retrofit of an air-cooled binary geothermal plant is presented as functions of both solar collector array cost and electricity sales price.

  8. Cost Contributors to Geothermal Power Production

    Nathwani, Jay; Mines, Greg

    2011-07-01

    The US Department of Energy Geothermal Technologies Office (DOE-GTO) has developed the tool Geothermal Electricity Technologies Evaluation Model (GETEM) to assess the levelized cost of electricity (LCOE) of power produced from geothermal resources. Recently modifications to GETEM allow the DOE-GTO to better assess how different factors impact the generation costs, including initial project risk, time required to complete a development, and development size. The model characterizes the costs associated with project risk by including the costs to evaluate and drill those sites that are considered but not developed for commercial power generation, as well as to assign higher costs to finance those activities having more risk. This paper discusses how the important parameters impact the magnitude project costs for different project scenarios. The cost distributions presented include capital cost recovery for the exploration, confirmation, well field completion and power plant construction, as well as the operation and maintenance (O&M) costs. The paper will present these cost distributions for both EGS and hydrothermal resources.

  11. Geothermal Risk Reduction via Geothermal/Solar Hybrid Power Plants. Final Report

    SciTech Connect (OSTI)

    Wendt, Daniel; Mines, Greg; Turchi, Craig; Zhu, Guangdong

    2015-11-01

    There are numerous technical merits associated with a renewable geothermal-solar hybrid plant concept. The performance of air-cooled binary plants is lowest when ambient temperatures are high due to the decrease in air-cooled binary plant performance that occurs when the working fluid condensing temperature, and consequently the turbine exhaust pressure, increases. Electrical power demand is generally at peak levels during periods of elevated ambient temperature and it is therefore especially important to utilities to be able to provide electrical power during these periods. The time periods in which air-cooled binary geothermal power plant performance is lowest generally correspond to periods of high solar insolation. Use of solar heat to increase air-cooled geothermal power plant performance during these periods can improve the correlation between power plant output and utility load curves. While solar energy is a renewable energy source with long term performance that can be accurately characterized, on shorter time scales of hours or days it can be highly intermittent. Concentrating solar power (CSP), aka solar-thermal, plants often incorporate thermal energy storage to ensure continued operation during cloud events or after sunset. Hybridization with a geothermal power plant can eliminate the need for thermal storage due to the constant availability of geothermal heat. In addition to the elimination of the requirement for solar thermal storage, the ability of a geothermal/solar-thermal hybrid plant to share a common power block can reduce capital costs relative to separate, stand-alone geothermal and solar-thermal power plant installations. The common occurrence of long-term geothermal resource productivity decline provides additional motivation to consider the use of hybrid power plants in geothermal power production. Geothermal resource productivity decline is a source of significant risk in geothermal power generation. Many, if not all, geothermal resources

    1984-10-01

    The status of geothermal power plants as of mid-1984 is given. There are 15 countries with active plants, and France (Guadeloupe) is expected to join the roster in the near future. The total number of operating units (defined as individual turbo-generator sets) is 145; the total installed capacity is somewhat less than 3770 MW. If plans for additional plants are met, the total could jump by more than 200 MW over the next two years. Recent growth is presented and the worldwide installed capacity is traced. A graphic portrayal of the growth pattern is presented. The countries that will be most responsible for sustaining this growth are the US, the Philippines, Mexico, and Indonesia. Other countries that will contribute significantly include Italy, Japan, Kenya, Nicaragua, and Turkey. The following countries do not now have any geothermal plants but may bring some online by 1990: Guatemala, Costa Rica, Greece, St. Lucia, Thailand, and Ethiopia.

  18. Small geothermal electric systems for remote powering

    SciTech Connect (OSTI)

    Entingh, Daniel J.; Easwaran, Eyob.; McLarty, Lynn

    1994-08-08

    This report describes conditions and costs at which quite small (100 to 1,000 kilowatt) geothermal systems could be used for off-grid powering at remote locations. This is a first step in a larger process of determining locations and conditions at which markets for such systems could be developed. The results suggest that small geothermal systems offer substantial economic and environmental advantages for powering off-grid towns and villages. Geothermal power is most likely to be economic if the system size is 300 kW or greater, down to reservoir temperatures of 100{degree}C. For system sizes smaller than 300 kW, the economics can be favorable if the reservoir temperature is about 120{degree}C or above. Important markets include sites remote from grids in many developing and developed countries. Estimates of geothermal resources in many developing countries are shown.

  19. Monitoring Biological Activity at Geothermal Power Plants

    Peter Pryfogle

    2005-09-01

    The economic impact of microbial growth in geothermal power plants has been estimated to be as high as $500,000 annually for a 100 MWe plant. Many methods are available to monitor biological activity at these facilities; however, very few plants have any on-line monitoring program in place. Metal coupon, selective culturing (MPN), total organic carbon (TOC), adenosine triphosphate (ATP), respirometry, phospholipid fatty acid (PLFA), and denaturing gradient gel electrophoresis (DGGE) characterizations have been conducted using water samples collected from geothermal plants located in California and Utah. In addition, the on-line performance of a commercial electrochemical monitor, the BIoGEORGE?, has been evaluated during extended deployments at geothermal facilities. This report provides a review of these techniques, presents data on their application from laboratory and field studies, and discusses their value in characterizing and monitoring biological activities at geothermal power plants.

    Geothermal energy comes from the internal heat of the Earth, and has been continuously exploited for the production of electricity in the United States since 1960. Currently, geothermal power is one of the ready-to-use baseload electricity generating technologies that is competing in the western United States with fossil fuel, nuclear and hydroelectric generation technologies to provide utilities and their customers with a reliable and economic source of electric power. Furthermore, the development of domestic geothermal resources, as an alternative to fossil fuel combustion technologies, has a number of associated environmental benefits. This report serves two functions. First, it provides a description of geothermal technology and a progress report on the commercial status of geothermal electric power generation. Second, it addresses the question of how much electricity might be competitively produced from the geothermal resource base. 19 figs., 15 tabs.

    Twenty-eight geothermal areas in Kenya were evaluated and prioritized for development. The prioritization was based on the potential size, resource temperature, level of exploration risk, location, and exploration/development costs for each geothermal area. Suswa, Eburru and Arus are found to offer the best short-term prospects for successful private power development. It was found that cost per kill developed are significantly lower for the larger (50MW) than for smaller-sized (10 or 20 NW) projects. In addition to plant size, the cost per kill developed is seen to be a function of resource temperature, generation mode (binary or flash cycle) and transmission distance.

    1996-12-31

    The Aluto-Langano Geothermal Pilot Plant will be the first geothermal power plant in Ethiopia. Its purpose is to utilize existing wells, drilled about a decade ago, to generate additional electricity for the power system and to prove the capability of the Aluto-Langano field to support expansion to 30 MWe. This paper discusses the evaluation of possible production wells, in combination with three power cycle options, leading to selection of a preferred development concept. Despite the small size of the pilot plant, the high elevation of the site, and the very high gas content of the field, a condensing unit was selected. Particular design features proposed for the steamfield and power plant are explained, including those that reflect the pilot plant nature of the project.

  9. Low-temperature Stirling Engine for Geothermal Electricity Generation

    SciTech Connect (OSTI)

    Stillman, Greg; Weaver, Samuel P.

    2013-03-27

    Up to 2700 terawatt-hours per year of geothermal electricity generation capacity has been shown to be available within North America, typically with wells drilled into geologically active regions of the earth's crust where this energy is concentrated (Huttrer, 2001). Of this potential, about half is considered to have temperatures high enough for conventional (steam-based) power production, while the other half requires unconventional power conversion approaches, such as organic Rankine cycle systems or Stirling engines. If captured and converted effectively, geothermal power generation could replace up to 100GW of fossil fuel electric power generation, leading to a significant reduction of US power sector emissions. In addition, with the rapid growth of hydro-fracking in oil and gas production, there are smaller-scale distributed power generation opportunities in heated liquids that are co-produced with the main products. Since 2006, Cool Energy, Inc. (CEI) has designed, fabricated and tested four generations of low-temperature (100°C to 300°C) Stirling engine power conversion equipment. The electric power output of these engines has been demonstrated at over 2kWe and over 16% thermal conversion efficiency for an input temperature of 215°C and a rejection temperature of 15°C. Initial pilot units have been shipped to development partners for further testing and validation, and significantly larger engines (20+ kWe) have been shown to be feasible and conceptually designed. Originally intended for waste heat recovery (WHR) applications, these engines are easily adaptable to geothermal heat sources, as the heat supply temperatures are similar. Both the current and the 20+ kWe designs use novel approaches of self-lubricating, low-wear-rate bearing surfaces, non-metallic regenerators, and high-effectiveness heat exchangers. By extending CEI's current 3 kWe SolarHeart® Engine into the tens of kWe range, many additional applications are possible, as one 20 k

    Altseimer, J.H.; Edeskuty, F.J.

    1986-01-01

    Many countries have the potential to use geothermal energy for both power production and process heat applications. Two Los Alamos programs have studied the most effective use of geothermal energy in St. Lucia and Guatemala. The general objectives are (1) to reduce oil imports; (2) develop employment opportunities; and (3) make products more competitive. The initial St. Lucia studies emphasized power generation but a number of applications for the power plant's residual heat were also found and costs and systems have been determined. The costs of geothermal heat compare favorably with heat from other sources such as oil. In Guatemala, the development of the nation's first geothermal field is well advanced. Process heat applications and their coordination with power generation plants are being studied at Los Alamos. Guatemala has at least two fields that appear suitable for power and heat production. These fields are close to urban centers and to many potential heat applications.

  18. The status and future of geothermal power

    SciTech Connect (OSTI)

    Kutscher, Charles F.

    2000-08-01

    Geothermal electricity production in the United States began in 1960. Today there are over 20 plants in the western United States providing a total of about 2,200 MW of clean and reliable electricity. Currently identified resources could provide over 20,000 MW of power in the U.S., and undiscovered resources might provide 5 times that amount. In the 1990s industry growth slowed due to the loss of market incentives and competition from natural gas. However, increased interest in clean energy sources, ongoing technological improvements, and renewed opportunities abroad hold promise for a resurgence in the industry. This review paper covers the status of the technology, the issues faced, and the latest research. While the focus is on geothermal in the U.S., a brief description of the large international market is included.

  10. City of Klamath Falls, Oregon Geothermal Power Plant Feasibility Study

    SciTech Connect (OSTI)

    Brian Brown, PE; Stephen Anderson, PE, Bety Riley

    2011-07-31

    The purpose of the Klamath Falls project is to demonstrate the effectiveness of a combined thermal distribution system and power generation facility. The city of Klamath Falls operates a geothermal district heating system which would appear to be an attractive opportunity to install a power generation system. Since the two wells have operated reliably and consistently over many years, no new sources or resource exploration would be necessary. It appears that it will cost more to construct, operate, maintain and amortize a proposed geothermal facility than the long?term value of the power it would produce. The success of a future project will be determined by whether utility power production costs will remain low and whether costs of construction, operations, or financing may be reduced. There are areas that it would be possible to reduce construction cost. More detailed design could enable the city to obtain more precise quotes for components and construction, resulting in reduction in contingency projections. The current level of the contingency for uncertainty of costs is between $200,000 and $300,000. Another key issue with this project appears to be operation cost. While it is expected that only minimal routine monitoring and operating expenses will occur, the cost of water supply and waste water disposal represents nearly one quarter of the value of the power. If the cost of water alone could be reduced, the project could become viable. In addition, the projected cost of insurance may be lower than estimated under a city?wide policy. No provisions have been made for utilization of federal tax incentives. If a transaction with a third-party owner/taxpayer were to be negotiated, perhaps the net cost of ownership could be reduced. It is recommended that these options be investigated to determine if the costs and benefits could be brought together. The project has good potential, but like many alternative energy projects today, they only work economically if the

    2014-07-07

    A variable phase turbine assembly will be designed and manufactured having a turbine, operable with transcritical, two-phase or vapor flow, and a generator – on the same shaft supported by process lubricated bearings. The assembly will be hermetically sealed and the generator cooled by the refrigerant. A compact plate-fin heat exchanger or tube and shell heat exchanger will be used to transfer heat from the geothermal fluid to the refrigerant. The demonstration turbine will be operated separately with two-phase flow and with vapor flow to demonstrate performance and applicability to the entire range of low temperature geothermal resources. The vapor leaving the turbine is condensed in a plate-fin refrigerant condenser. The heat exchanger, variable phase turbine assembly and condenser are all mounted on single skids to enable factory assembly and checkout and minimize installation costs. The system will be demonstrated using low temperature (237F) well flow from an existing large geothermal field. The net power generated, 1 megawatt, will be fed into the existing power system at the demonstration site. The system will demonstrate reliable generation of inexpensive power from low temperature resources. The system will be designed for mass manufacturing and factory assembly and should cost less than $1,200/kWe installed, when manufactured in large quantities. The estimated cost of power for 300F resources is predicted to be less than 5 cents/kWh. This should enable a substantial increase in power generated from low temperature geothermal resources.

    The 125 MW Upper Mahiao power plant, the first geothermal power project to be financed under a Build-Own-Operate-and-Transfer (BOOT) arrangement in the Philippines, expected to complete its start-up testing in August of this year. This plant uses Ormat`s environmentally benign technology and is both the largest geothermal steam/binary combined cycle plant as well as the largest geothermal power plant utilizing air cooled condensers. The Ormat designed and constructed plant was developed under a fast track program, with some two years from the April 1994 contract signing through design, engineering, construction and startup. The plant is owned and operated by a subsidiary of CalEnergy Co., Inc. and supplies power to PNOC-Energy Development Corporation for the National Power Corporation (Napocor) national power grid in the Philippines.

    A life-cycle energy and greenhouse gas emissions analysis has been conducted with Argonne National Laboratory's expanded Greenhouse Gases, Regulated Emissions, and Energy Use in Transportation (GREET) model for geothermal power-generating technologies, including enhanced geothermal, hydrothermal flash, and hydrothermal binary technologies. As a basis of comparison, a similar analysis has been conducted for other power-generating systems, including coal, natural gas combined cycle, nuclear, hydroelectric, wind, photovoltaic, and biomass by expanding the GREET model to include power plant construction for these latter systems with literature data. In this way, the GREET model has been expanded to include plant construction, as well as the usual fuel production and consumption stages of power plant life cycles. For the plant construction phase, on a per-megawatt (MW) output basis, conventional power plants in general are found to require less steel and concrete than renewable power systems. With the exception of the concrete requirements for gravity dam hydroelectric, enhanced geothermal and hydrothermal binary used more of these materials per MW than other renewable power-generation systems. Energy and greenhouse gas (GHG) ratios for the infrastructure and other life-cycle stages have also been developed in this study per kilowatt-hour (kWh) of electricity output by taking into account both plant capacity and plant lifetime. Generally, energy burdens per energy output associated with plant infrastructure are higher for renewable systems than conventional ones. GHG emissions per kWh of electricity output for plant construction follow a similar trend. Although some of the renewable systems have GHG emissions during plant operation, they are much smaller than those emitted by fossil fuel thermoelectric systems. Binary geothermal systems have virtually insignificant GHG emissions compared to fossil systems. Taking into account plant construction and operation, the GREET

    Moyer, R.D.

    A peak power ratio generator is described for measuring, in combination with a conventional power meter, the peak power level of extremely narrow pulses in the gigahertz radio frequency bands. The present invention in a preferred embodiment utilizes a tunnel diode and a back diode combination in a detector circuit as the only high speed elements. The high speed tunnel diode provides a bistable signal and serves as a memory device of the input pulses for the remaining, slower components. A hybrid digital and analog loop maintains the peak power level of a reference channel at a known amount. Thus, by measuring the average power levels of the reference signal and the source signal, the peak power level of the source signal can be determined.

    DOE Patents [OSTI]

    Morris, David C

    2014-02-25

    A system and method for harvesting the kinetic energy of a fluid flow for power generation with a vertically oriented, aerodynamic wing structure comprising one or more airfoil elements pivotably attached to a mast. When activated by the moving fluid stream, the wing structure oscillates back and forth, generating lift first in one direction then in the opposite direction. This oscillating movement is converted to unidirectional rotational movement in order to provide motive power to an electricity generator. Unlike other oscillating devices, this device is designed to harvest the maximum aerodynamic lift forces available for a given oscillation cycle. Because the system is not subjected to the same intense forces and stresses as turbine systems, it can be constructed less expensively, reducing the cost of electricity generation. The system can be grouped in more compact clusters, be less evident in the landscape, and present reduced risk to avian species.

    1983-08-01

    Through development of a separator/expander engine EPRI is improving the efficiency of single flash geothermal power systems. Under cost-shared contracts with Biphase Energy Systems and Utah Power and Light Company (UP and L), a wellhead power generating system has been built and tested. The wellhead unit has been operated for 4000 hours at Roosevelt Hot Springs near Milford, Utah. Phillips Petroleum Company operates the geothermal field at this site. The rotary separator turbine (RST) is a separating expander that increases the resource utilization efficiency by extracting power upstream of a steam turbine in either a 1-stage or 2-stage flash power system. The first power output was achieved October 28, 1981, six weeks after arrival of the RST at the site. The RST system produced 3270 MWh(e) gross and 2770 MWh(e) net to the UP and L grid. Total equivalent power produced by the wellhead RST (actual power output of the RST plus the power obtainable from the steam flow out of the RST) is 15 to 20 percent above the power that would be produced by an optimum 1-stage direct flash plant operated on the same geothermal well.

    2013-06-04

    Life cycle analysis (LCA) is an environmental assessment method that quantifies the environmental performance of a product system over its entire lifetime, from cradle to grave. Based on a set of relevant metrics, the method is aptly suited for comparing the environmental performance of competing products systems. This file contains LCA data and results for electric power production including geothermal power. The LCA for electric power has been broken down into two life cycle stages, namely plant and fuel cycles. Relevant metrics include the energy ratio and greenhouse gas (GHG) ratios, where the former is the ratio of system input energy to total lifetime electrical energy out and the latter is the ratio of the sum of all incurred greenhouse gases (in CO2 equivalents) divided by the same energy output. Specific information included herein are material to power (MPR) ratios for a range of power technologies for conventional thermoelectric, renewables (including three geothermal power technologies), and coproduced natural gas/geothermal power. For the geothermal power scenarios, the MPRs include the casing, cement, diesel, and water requirements for drilling wells and topside piping. Also included herein are energy and GHG ratios for plant and fuel cycle stages for the range of considered electricity generating technologies. Some of this information are MPR data extracted directly from the literature or from models (eg. ICARUS – a subset of ASPEN models) and others (energy and GHG ratios) are results calculated using GREET models and MPR data. MPR data for wells included herein were based on the Argonne well materials model and GETEM well count results.

    2012-02-08

    A study has been conducted on the material demand and life-cycle energy and emissions performance of power-generating technologies in addition to those reported in Part I of this series. The additional technologies included concentrated solar power, integrated gasification combined cycle, and a fossil/renewable (termed hybrid) geothermal technology, more specifically, co-produced gas and electric power plants from geo-pressured gas and electric (GPGE) sites. For the latter, two cases were considered: gas and electricity export and electricity-only export. Also modeled were cement, steel and diesel fuel requirements for drilling geothermal wells as a function of well depth. The impact of the construction activities in the building of plants was also estimated. The results of this study are consistent with previously reported trends found in Part I of this series. Among all the technologies considered, fossil combustion-based power plants have the lowest material demand for their construction and composition. On the other hand, conventional fossil-based power technologies have the highest greenhouse gas (GHG) emissions, followed by the hybrid and then two of the renewable power systems, namely hydrothermal flash power and biomass-based combustion power. GHG emissions from U.S. geothermal flash plants were also discussed, estimates provided, and data needs identified. Of the GPGE scenarios modeled, the all-electric scenario had the highest GHG emissions. Similar trends were found for other combustion emissions.

  19. Evaluation of a superheater enhanced geothermal steam power plant in the Geysers area. Final report

    SciTech Connect (OSTI)

    Janes, J.

    1984-06-01

    This study was conducted to determine the attainable generation increase and to evaluate the economic merits of superheating the steam that could be used in future geothermal steam power plants in the Geyser-Calistoga Known Geothermal Resource Area (KGRA). It was determined that using a direct gas-fired superheater offers no economic advantages over the existing geothermal power plants. If the geothermal steam is heated to 900/sup 0/F by using the exhaust energy from a gas turbine of currently available performance, the net reference plant output would increase from 65 MW to 159 MW (net). Such hybrid plants are cost effective under certain conditions identified in this document. The power output from the residual Geyser area steam resource, now equivalent to 1437 MW, would be more than doubled by employing in the future gas turbine enhancement. The fossil fuel consumed in these plants would be used more efficiently than in any other fossil-fueled power plant in California. Due to an increase in evaporative losses in the cooling towers, the viability of the superheating concept is contingent on development of some of the water resources in the Geysers-Calistoga area to provide the necessary makeup water.

In the generation of required power, thermoelectric element drives a solid-state converter which is controlled by input current rather than input voltage and operates efficiently for a high signal-plus-noise to signal ratio of current. The solid-state converter has the voltage gain necessary to deliver the required voltage at the low input of the thermoelectric element.

    Five deep wells have been drilled on the Island of Milos, Greece, identifying a high-temperature, high-enthalpy geothermal reservoir. The thermodynamic properties of the fluid, and the estimated porosity and presumed thickness of the formation suggest a fluid and heat storage capacity that could support a 60 MWe power plant for 85 years or a 120 MWe for half that time. The existing five wells can deliver 180 t/h of steam at 10 bar abs pressure, capable of generating a maximum electric power output of slightly less than 20 MWe. This paper describes the geology, the drilling and the well testing results pertaining to the five wells, and discusses the reservoir potential for a 60 MWe geothermal power plant.

It is part of a larger effort to compare the life cycle impacts of large-scale geothermal electricity generation with other power generation technologies. The results of the life cycle analysis are summarized in a companion report, Life Cycle Analysis Results of Geothermal Systems in Comparison to Other Power Systems. This report is divided into six chapters. Chapter 1 gives the background of the project and its purpose, which is to inform power plant design and operations. Chapter 2 summarizes the geothermal electricity generation technologies evaluated in this study, which include conventional hydrothermal flash and binary systems, as well as enhanced geothermal systems (EGS) that rely on engineering a productive reservoir where heat exists but water availability or permeability may be limited. Chapter 3 describes the methods and approach to this work and identifies the four power plant scenarios evaluated: a 20-MW EGS plant, a 50-MW EGS plant, a 10-MW binary plant, and a 50-MW flash plant. The two EGS scenarios include hydraulic stimulation activities within the construction stage of the life cycle and assume binary power generation during operations. The EGS and binary scenarios are assumed to be air-cooled power plants, whereas the flash plant is assumed to rely on evaporative cooling. The well field and power plant design for the scenario were based on simulations using DOE's Geothermal Economic Technology Evaluation Model (GETEM). Chapter 4 presents the water requirements for the power plant life cycle for the scenarios evaluated. Geology, reservoir

    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.

    1999-07-01

    Performance evaluation of a 12.8 MW single-flash design geothermal power plant in Northern Nevada is conducted using actual plant operating data, and potential improvement sites are identified. The unused geothermal brine reinjected back to the ground is determined to represent about 50% of the energy and 40% of the exergy available in the reservoir. The first and second law efficiencies of the plant are determined to be 6% and 22%, respectively. Optimizing the existing single-flash system is shown to increase the net power output by up to 4%. Some well-known geothermal power generation technologies including double-glass, binary, and, combined flash/binary designs as alternative to the existing system are evaluated and their optimum operating conditions are determined. It is found that a double-flash design, a binary design, and a combined flash/binary design can increase the net power output by up to 31%, 35%, and 54%, respectively, at optimum operating conditions. An economic comparison of these designs appears to favor the combined flash/binary design, followed by the double-glass design.

  1. Worldwide Geothermal Power Plants: Status as of June 1980

    DiPippo, Ronald

    1980-12-01

    There are 100 geothermal power units now in operation throughout 12 countries, with a total installed capacity of just over 2110 MW. The average unit thus is rated at 21.1 MW. Newer units may be broadly classified as follows: (a) wellhead units of less than 5 MW; (b) small plants of about 10 MW; (c) medium plants of 30-35 MW; (d) large plants of about 55 MW; and (e) complexes typically consisting of several 55 MW units in a large geothermal field. There is a trend toward turbine units of the double-flow type with a 55 MW rating, used either alone or in a tandem-compound arrangement giving 110 MW in a single power house. This is particularly evident at The Geysers field in California. Double-flash units (separated-steam followed by a surface flash) are suited to high quality reservoirs having high temperature, high steam fractions at the wellhead, and low scaling potential. Single-flash units (separated steam) may be called for where scaling by the spent brine is a potential problem for the liquid disposal system. Binary plants are being used for some very low temperature reservoirs, particularly in the People's Republic of China, albeit in extremely small units. A large-scale pilot plant of the binary type is being planned for the Imperial Valley of California.

    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.

    To reduce chemical costs at geothermal power plants, we are investigating: (a) improved chemical processes associated with H{sub 2}S abatement techniques, and (b) the use of cross dispersive infrared spectrometry to monitor accurately, reliably, and continuously H{sub 2}S emissions from cooling towers. The latter is a new type of infrared optical technology developed by LLNL for non-proliferation verification. Initial work is focused at The Geysers in cooperation with Pacific Gas and Electric. Methods for deploying the spectrometer on-site at The Geysers are being developed. Chemical analysis of solutions involved in H{sub 2}S abatement technologies is continuing to isolate the chemical forms of sulfur produced.

    In the spring of 2000, the National Renewable Energy Laboratory issued a Request for Proposal for the construction of small-scale (300 kilowatt [kW] to 1 megawatt [MW]) geothermal power plants in the western United States. Five projects were selected for funding. Of these five, subcontracts have been completed for three, and preliminary design work is being conducted. The three projects currently under contract represent a variety of concepts and locations: a 1-MW evaporatively enhanced, air-cooled binary-cycle plant in Nevada; a 1-MW water-cooled Kalina-cycle plant in New Mexico; and a 750-kW low-temperature flash plant in Utah. All three also incorporate direct heating: onion dehydration, heating for a fish hatchery, and greenhouse heating, respectively. These projects are expected to begin operation between April 2002 and September 2003. In each case, detailed data on performance and costs will be taken over a 3-year period.

    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.

    Hays, Lance G.

    2014-11-18

    Phase 1 of the investigation of improvements to low temperature geothermal power systems was completed. The improvements considered were reduction of scaling in heat exchangers and a hermetic turbine generator (eliminating seals, seal system, gearbox, and lube oil system). A scaling test system with several experiments was designed and operated at Coso geothermal resource with brine having a high scaling potential. Several methods were investigated at the brine temperature of 235 ºF. One method, circulation of abradable balls through the brine passages, was found to substantially reduce scale deposits. The test heat exchanger was operated with brine outlet temperatures as low as 125 ºF, which enables increased heat input available to power conversion systems. For advanced low temperature cycles, such as the Variable Phase Cycle (VPC) or Kalina Cycle, the lower brine temperature will result in a 20-30% increase in power production from low temperature resources. A preliminary design of an abradable ball system (ABS) was done for the heat exchanger of the 1 megawatt VPC system at Coso resource. The ABS will be installed and demonstrated in Phase 2 of this project, increasing the power production above that possible with the present 175 ºF brine outlet limit. A hermetic turbine generator (TGH) was designed and manufacturing drawings produced. This unit will use the working fluid (R134a) to lubricate the bearings and cool the generator. The 200 kW turbine directly drives the generator, eliminating a gearbox and lube oil system. Elimination of external seals eliminates the potential of leakage of the refrigerant or hydrocarbon working fluids, resulting in environmental improvement. A similar design has been demonstrated by Energent in an ORC waste heat recovery system. The existing VPC power plant at Coso was modified to enable the “piggyback” demonstration of the TGH. The existing heat exchanger, pumps, and condenser will be operated to provide the required

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.

It is intended for geothermal experts in either the private or public sector who are less familiar with how the electricity system operates beyond the geothermal plant. 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.

    1981-06-01

    The water-related constraints, which may be among the most complex and variable of the issues facing commercialization of geothermal energy, are discussed under three headings: (1) water requirements of geothermal power stations, (2) resource characteristics of the most promising hydrothermal areas and regional and local water supply situations, and (3) legal issues confronting potential users of water at geothermal power plants in the states in which the resource areas are located. A total of 25 geothermal resource areas in California, New Mexico, Oregon, Idaho, Utah, Hawaii, and Alaska were studied. Each had a hydrothermal resource temperature in excess of 150/sup 0/C (300/sup 0/F) and an estimated 30-year potential of greater than 100-MW(e) capacity.

  2. Cooling tower fill fouling control in a geothermal power plant

    1998-12-31

    Since its first introduction to the market in the 1970s, cooling tower film fill technology has significantly increased thermal performance and reduced the size of cooling towers. However, the narrow spaces between film fill sheets make them susceptible to fouling. Without proper chemical treatment, deposits can accumulate within the film fill resulting in reduced tower efficiency, increased fouling and plugging of the fill. These phenomena could eventually lead to collapse of the tower structure, This paper describes a new approach to remedy the high efficiency film fill fouling problem in a geothermal power plant. The plant has a long history of fill fouling problems due to a very complex make-up water chemistry and desert-related environmental conditions. In recent years, various biocide and biodispersant treatments have significantly improved fouling control by slowing down tower fill deposition rates. However, no program has been successful in reducing fill weights, especially during the summer months. Within six weeks after starting a new control program, the average weight of the tower fill deposits dropped 22% and thermal performance of the cooling tower increased 20%. The treatment resulted in significant improvements in cooling tower operation and power production efficiency.

    2015-04-14

    Traditional power generation systems using thermoelectric power generators are designed to operate most efficiently for a single operating condition. The present invention provides a power generation system in which the characteristics of the thermoelectrics, the flow of the thermal power, and the operational characteristics of the power generator are monitored and controlled such that higher operation efficiencies and/or higher output powers can be maintained with variably thermal power input. Such a system is particularly beneficial in variable thermal power source systems, such as recovering power from the waste heat generated in the exhaust of combustion engines.

    1983-06-30

    A study of advancements in power plant designs for use at geothermal resources in the low to moderate (300 to 400F) temperature range is reported. In 3 case studies, the benefits of R and D to achieve these advancements are evaluated in terms of expected increases in installed geothermal generating capacity over the next 2 decades. A parametric sensitivity study is discussed which analyzes differential power development for combinations of power plant efficiency and capitol cost. Affordable tradeoffs between plant performance and capital costs are illustrated. The independent review and analysis of the expected costs of construction, operation and maintenance of the Heber Binary Cycle Geothermal Power Demonstration Plant are described. Included in this assessment is an analysis of each of the major cost components of the project, including (1) construction cost, (2) well field development costs, (3) fluid purchase costs, and (4) well field and power plant operation and maintenance costs. The total cost of power generated from the Heber Plant (in terms of mills per kWh) is then compared to the cost of power from alternative fossil-fueled base load units. Also evaluated are the provisions of both: (a) the Cooperative Agreement between the federal government and San Diego Gas and Electric (SDG and E); and (b) the Geothermal Heat Sales Contract with Union Oil Company.

    Production and chemical data have been compiled and analyzed on a six-month averaged basis for the first four years of electric energy generation with five 5-MW wellhead generators at the Los Azufres geothermal field. The data were evaluated with respect to the extent of observable thermal drawdown of the reservoir from 25 MW of generation in relation to the estimated capacity of the field of several hundred megawatts of power. The analysis updates the previous one compiled after the first two years of continuous production, at which time the results indicated that differences in reservoir temperature estimated from geochemical thermometers and wellhead production data were not statistically significant based on the number of data and the standard deviations. Analysis of the data after four years of operation were made for the larger number of data and smaller standard deviations. The results review the adequacy of the sampling frequency and the reliability of the measurements from statistical t-Test of the means of the first and second two-year periods. 3 figs., 5 tabs., 20 refs.

    The Philippine geothermal energy development is now considered in a state of maturity. After more than 20 years of geothermal experience, the total geothermal installed capacity in the Philippines reached 1,455 MW (1996) or about 12% of the total installed power plant capacity. This also enabled the Philippines to become the second largest producer of geothermal energy in the world. The country`s track record in harnessing geothermal energy is considered a revelation, as it continues with its vision of {open_quotes}full steam ahead{close_quotes}, originally conceived when commercial geothermal operation started in 1973.

    1988-01-01

    In December, 1975, work began on Hawaii's first successful geothermal well in the East Rift Zone of Kilauea Volcano on the Island of Hawaii (Figure 1). By July, 1976, the well, named Hawaii Geothermal Project - A (HGP-A), was complete to a depth of almost 2 km and had encountered a volcanically driven hydrothermal system having a temperature in excess of 358{degrees} C and a fluid chemistry composed of a mixture of seawater, meteoric water, and volcanic volatiles. The principal chemical constituents of the fluid are listed in Table I. Note the relatively high H{sub 2}S concentration which ranged 900 - 1,000 ppmw. During the early testing of the well, the superheated geothermal fluid was allowed to flash at normal atmospheric pressure with steam and noncondensable gases being released unabated into the atmosphere. The high H{sub 2}S and noise (120 dBA) levels and the close proximity of the Leilani Estates residential subdivision were cause for concern and efforts were thus made to mitigate these impacts. Certain elements of the initial test protocol required that the well be allowed to flow freely and unabated. During these periods public notice and prewarning were the most feasible means of mitigation. At other times, the mixed fluid is separated into steam and brine phases with the steam phase being treated with NaOH and then released through a rock muffler. The brine phase is released through a separate muffling system. Chemical treatment of the stream with NaOH converts the H{sub 2}S into a soluble sulfide salt through the following reaction: H{sub 2}S(g) + NaOH {r arrow} NaHS(s) + H{sub 2}O. This paper discusses early flow testing revealed that the well was able to produce a steady flow of approximately 50,000 kg per hour of steam and water at a pressure of 1200 kPA and thus appeared suitable for power generation.

    This project will investigate a previously unidentified geothermal energy resource, opening broad new frontiers to geothermal development. Data collected by industry during oil and gas development demonstrate deep permeable strata with temperatures {ge} 150 C, within the optimum window for binary power plant operation. The project will delineate Deep Permeable Strata Geothermal Energy (DPSGE) assets in the Permian Basin of western Texas and southeastern New Mexico. Presently, geothermal electrical power generation is limited to proximity to shallow, high-temperature igneous heat sources. This geographically restricts geothermal development. Delineation of a new, less geographically constrained geothermal energy source will stimulate geothermal development, increasing available clean, renewable world energy reserves. This proposal will stimulate geothermal reservoir exploration by identifying untapped and unrealized reservoirs of geothermal energy. DPSGE is present in many regions of the United States not presently considered as geothermally prospective. Development of this new energy source will promote geothermal use throughout the nation.

  17. Geothermal resource base of the world: a revision of the Electric Power Research Institute's estimate

    SciTech Connect (OSTI)

    Aldrich, M.J.; Laughlin, A.W.; Gambill, D.T.

    1981-04-01

    Review of the Electric Power Research Institute's (EPRI) method for calculating the geothermal resource base of a country shows that modifications are needed for several of the assumptions used in the calculation. These modifications include: (1) separating geothermal belts into volcanic types with a geothermal gradient of 50{sup 0}C/km and complex types in which 80% of the area has a temperature gradient of 30{sup 0}C/km and 20% has a gradient of 45{sup 0}C/km, (2) using the actual mean annual temperature of a country rather than an assumed 15{sup 0}C average ambient temperature, and (3) making separate calculations for the resource stored in water/brine and that stored in rock. Comparison of this method (Revised EPRI) for calculating a geothermal resource base with other resource base estimates made from a heat flow map of Europe indicates that the technique yields reasonable values. The calculated geothermal resource bases, stored in water and rock to a depth of 5 km, for each country in the world are given. Approximately five times as much energy is stored in rock as is stored in water.

    Ethiopia is considered to be one of the favored countries with respect to high geothermal energy potential. If there is the possibility of exploiting the geothermal resource for direct use and electric energy generation, it can play an important role for the development of the country. Geothermal exploration in Ethiopia dates back to 1969. The country is currently using hydro and thermal plants as electric energy source. The proven geothermal fields, Langano and Tendaho may provide access for the utilization of the geothermal energy for electricity generation in the future. A geothermal power plant with a capacity of about 7 Mwe is expected to be on operation at Aluto Langano in the year 1998. In this paper the geothermal resources and the development problems in Ethiopia are discussed briefly.

  4. Remote-site power generation opportunities for Alaska

    SciTech Connect (OSTI)

    Jones, M.L.

    1997-03-01

    The Energy and Environmental Research Center (EERC) has been working with the Federal Energy Technology Center in Morgantown, West Virginia, to assess options for small, low-cost, environmental acceptable power generation for application in remote areas of Alaska. The goal of this activity was to reduce the use of fuel in Alaskan villages by developing small, low-cost power generation applications. Because of the abundance of high-quality coal throughout Alaska, emphasis was placed on clean coal applications, but other energy sources, including geothermal, wind, hydro, and coalbed methane, were also considered. The use of indigenous energy sources would provide cheaper cleaner power, reduce the need for PCE (Power Cost Equalization program) subsidies, increase self-sufficiency, and retain hard currency in the state while at the same time creating jobs in the region. The introduction of economical, small power generation systems into Alaska by US equipment suppliers and technology developers aided by the EERC would create the opportunities for these companies to learn how to engineer, package, transport, finance, and operate small systems in remote locations. All of this experience would put the US developers and equipment supply companies in an excellent position to export similar types of small power systems to rural areas or developing countries. Thus activities in this task that relate to determining the generic suitability of these technologies for other countries can increase US competitiveness and help US companies sell these technologies in foreign countries, increasing the number of US jobs. The bulk of this report is contained in the two appendices: Small alternative power workshop, topical report and Global market assessment of coalbed methane, fluidized-bed combustion, and coal-fired diesel technologies in remote applications.

  15. Means of improving the operating efficiency of air condensers at the Verkhne-Mutnovskaya Geothermal Power Plant in Kamchatka

    SciTech Connect (OSTI)

    Parshin, B. E.; Muratov, P. V.; Pashkevich, R. I.

    2007-07-15

    Operation of the Verkhne-Mutnovskaya Geothermal Power Plant (VMGPP) has revealed ineffective summer-time performance of air condensers (AC), which is caused by an insufficient heat reserve. Four alternate schemes are examined for improvement of the operational efficiency of the AC: replacement of the four-by five-tier heat-exchange modules; installation of high-output fans; a combination of the first two schemes; and, installation of additional sections in each power-generating set. Based on thermodynamic analysis that we have adapted for conditions at the VMGPP, it is established that the last alternate scheme is optimal, andwill have a payback period of six years, and a heat reserve of more than 40%, a figure approaching requirements now in force.
