Improving steam turbine efficiency  

SciTech Connect (OSTI)

This paper describes the condition of a significant number of fossil steam turbines operating in the United States and the maintenance practices used to improve their performance. Through the use of steam path audits conducted by the authors` company and by several utilities, a large data base of information on turbine heat rate, casing efficiency, and maintenance practices is available to help the power generation industry understand how different maintenance practices and steam path damage impact turbine performance. The data base reveals that turbine cycle heat rate is typically 5.23% poorer than design just prior to major outages. The degraded condition of steam turbines presents an opportunity for utilities to improve heat rate and reduce emissions without increasing fuel costs. The paper describes what losses typically contribute to the 5.23% heat rate degradation and how utilities can recover steam turbine performance through maintenance actions aimed at improving steam path efficiency.

Refines Efficiency Improvement  

SciTech Connect (OSTI)

Refinery processes that convert heavy oils to lighter distillate fuels require heating for distillation, hydrogen addition or carbon rejection (coking). Efficiency is limited by the formation of insoluble carbon-rich coke deposits. Heat exchangers and other refinery units must be shut down for mechanical coke removal, resulting in a significant loss of output and revenue. When a residuum is heated above the temperature at which pyrolysis occurs (340 C, 650 F), there is typically an induction period before coke formation begins (Magaril and Aksenova 1968, Wiehe 1993). To avoid fouling, refiners often stop heating a residuum before coke formation begins, using arbitrary criteria. In many cases, this heating is stopped sooner than need be, resulting in less than maximum product yield. Western Research Institute (WRI) has developed innovative Coking Index concepts (patent pending) which can be used for process control by refiners to heat residua to the threshold, but not beyond the point at which coke formation begins when petroleum residua materials are heated at pyrolysis temperatures (Schabron et al. 2001). The development of this universal predictor solves a long standing problem in petroleum refining. These Coking Indexes have great potential value in improving the efficiency of distillation processes. The Coking Indexes were found to apply to residua in a universal manner, and the theoretical basis for the indexes has been established (Schabron et al. 2001a, 2001b, 2001c). For the first time, a few simple measurements indicates how close undesired coke formation is on the coke formation induction time line. The Coking Indexes can lead to new process controls that can improve refinery distillation efficiency by several percentage points. Petroleum residua consist of an ordered continuum of solvated polar materials usually referred to as asphaltenes dispersed in a lower polarity solvent phase held together by intermediate polarity materials usually referred to as resins. The Coking Indexes focus on the amount of these intermediate polarity species since coke formation begins when these are depleted. Currently the Coking Indexes are determined by either titration or solubility measurements which must be performed in a laboratory. In the current work, various spectral, microscopic, and thermal techniques possibly leading to on-line analysis were explored for measuring the Coking Indexes.

Broader source: All U.S. Department of Energy (DOE) Office Webpages (Extended Search)

1 1 Green Cooling: Improving Chiller Efficiency This new chiller simulation module being developed by Building Performance Assurance Project members will help building managers compare optimal and actual chiller efficiency. Chillers are the single largest energy consumers in commercial buildings. These machines create peaks in electric power consumption, typically during summer afternoons. In fact, 23% of electricity generation is associated with powering chillers that use CFCs and HCFCs, ozone-depleting refrigerants. Satisfying the peak demand caused by chillers forces utilities to build new power plants. However, because chiller plants run the most when the weather is hot and very little at other times, their load factors - and hence the utilities' load factors (the percentage of time the

Efficiency improved turboprop. Technical memo  

SciTech Connect (OSTI)

Renewed attention has been focused on the efficiency of aircraft propulsion as the cost of fuel has risen. Studies conducted by NASA (1) to obtain fuel efficient aircraft have considered relatively highly-loaded turbo-prop systems. The disc loadings of these propellers are as much as four times higher than those on present turboprop aircraft. The higher disc loadings result in greater slipstream swirl and higher energy losses. Of primary importance is the radial distribution of the energy losses across the slipstream due to the tangential and axial velocities. This study presents the results of analysis defining the various sources of energy loss resulting from a swirling slipstream downstream of a propeller. Experimental data are presented demonstrating the presence of such losses and a propeller configuration discussed which offers improved propulsive performance when relatively highly-loaded propellers are employed.

Strategies to Improve Industrial Energy Efficiency  

Science Journals Connector (OSTI)

Abstract The broad topic of efficiency is investigated within the context of the general manufacturing sector, which includes anything from computing and electronics to food and textile products, and consumes enormous amounts of energy in order to generate the goods and services we use today. This is unsurprising as it stands to reason that in order to operate the necessary equipment and facilities to produce these products a significant amount of energy and resources must be expended. However, most manufacturing facilities are not operated at a highly efficient rate, in terms of both waste heat and materials. As a result, a number of opportunities exist to develop a more efficient, sustainable general manufacturing sector. This topic has been well researched in the past in terms of the losses encountered during various general manufacturing process streams, however, less literature exists which attempts to outline an appropriate efficiency loss mitigation strategy for companies to implement. In fact, the Trottier Energy Futures Project, which is, in collaboration with the David Suzuki Foundation, creating an energy roadmap for Canada, has devoted one of its eleven key challenges for creating a more sustainable, low-carbon future for Canada to general manufacturing efficiency improvement. This paper will discuss appropriate efficiency loss mitigation strategies for companies.

Wireless Sensor Wireless Sensor Technology Overview In most buildings, space conditions are controlled and coordinated by a building automation system (BAS). A BAS can provide temperature visualization information with dashboard displays through a person-machine interface (PMI).

Unfortunately, these data centers do not have adequate auto- mation systems or visualization tools to monitor or manage these cooling units efficiently.

Superefficient Refrigerators: Opportunities and Challenges for Efficiency Improvement Globally  

SciTech Connect (OSTI)

As an energy-intensive mainstream product, residential refrigerators present a significant opportunity to reduce electricity consumption through energy efficiency improvements. Refrigerators expend a considerable amount of electricity during normal use, typically consuming between 100 to 1,000 kWh of electricity per annum. This paper presents the results of a technical analysis done for refrigerators in support of the Super-efficient Equipment and Appliance Deployment (SEAD) initiative. Beginning from a base case representative of the average unit sold in India, we analyze efficiency improvement options and their corresponding costs to build a cost-versus-efficiency relationship. We then consider design improvement options that are known to be the most cost effective and that can improve efficiency given current design configurations. We also analyze and present additional super-efficient options, such as vacuum-insulated panels. We estimate the cost of conserved electricity for the various options, allowing flexible program design for market transformation programs toward higher efficiency. We estimate ~;;160TWh/year of energy savings are cost effective in 2030, indicating significant potential for efficiency improvement in refrigerators in SEAD economies and China.

Potentials and policy implications of energy and material efficiency improvement  

SciTech Connect (OSTI)

There is a growing awareness of the serious problems associated with the provision of sufficient energy to meet human needs and to fuel economic growth world-wide. This has pointed to the need for energy and material efficiency, which would reduce air, water and thermal pollution, as well as waste production. Increasing energy and material efficiency also have the benefits of increased employment, improved balance of imports and exports, increased security of energy supply, and adopting environmentally advantageous energy supply. A large potential exists for energy savings through energy and material efficiency improvements. Technologies are not now, nor will they be, in the foreseeable future, the limiting factors with regard to continuing energy efficiency improvements. There are serious barriers to energy efficiency improvement, including unwillingness to invest, lack of available and accessible information, economic disincentives and organizational barriers. A wide range of policy instruments, as well as innovative approaches have been tried in some countries in order to achieve the desired energy efficiency approaches. These include: regulation and guidelines; economic instruments and incentives; voluntary agreements and actions, information, education and training; and research, development and demonstration. An area that requires particular attention is that of improved international co-operation to develop policy instruments and technologies to meet the needs of developing countries. Material efficiency has not received the attention that it deserves. Consequently, there is a dearth of data on the qualities and quantities for final consumption, thus, making it difficult to formulate policies. Available data, however, suggest that there is a large potential for improved use of many materials in industrialized countries.

Mao, and Ralph Greif Journal International Journal of Energy Research Volume 34 Start Page 1257 Issue 14 Pagination 1257-1271 Date Published 11/2010 Keywords high-concentrator photovoltaic efficiency, two-phase flow cooling applications Abstract The potential of increasing high-concentrator photovoltaic cell efficiency by cooling with two-phase flow is analyzed. The governing energy equations were used to predict cell temperature distributions and cell efficiencies for a photovoltaic cell under 100 suns' concentration. Several design conditions were taken into consideration in the analysis, including cooling channel height, working fluid type (between water and R134a), working fluid inlet temperature, pressure, and mass flow rate. It was observed that the dominant parameter for increasing cell efficiency was the working fluid saturation temperature, which itself is affected by a number of the aforementioned design parameters. The results show R134a at low inlet pressures to be highly effective in this two-phase cooling design.

Characterization of Process Efficiency Improvement in Laser Additive Manufacturing  

Science Journals Connector (OSTI)

Abstract Laser additive manufacturing (LAM) enables production of complex parts with good mechanical properties. Nevertheless, part manufacturing is still relatively slow and the process efficiency could be improved to achieve total breakthrough into series production. In this study, the process efficiency improvements via higher laser power and thicker powder layers are studied. Effect of the building parameters must be understood when increasing build rate. Track-wise and layer-wise manufacturing strategy involves different independent and dependent thermal cycles which all affect part properties. Effects of the processing parameters such as speed and power on single-track formation are examined, since the part quality depend strongly on each single-track and layer. It was concluded that heat input has important effect on the penetration depth and possibility to melt thicker powder layers. These were noticed to be crucial for improving process efficiency.

Improved Magnetic Field Generation Efficiency and Higher Temperature Spheromak Plasmas  

SciTech Connect (OSTI)

New understanding of the mechanisms governing the observed magnetic field generation limits on the sustained spheromak physics experiment has been obtained. Extending the duration of magnetic helicity injection during the formation of a spheromak and optimizing the ratio of injected current to bias flux produce higher magnetic field plasmas with record spheromak electron temperatures. To explore magnetic field buildup efficiency limits, the confinement region geometry was varied resulting in improved field buildup efficiencies.

Determining Benefits and Costs of Improved Water Heater Efficiencies Determining Benefits and Costs of Improved Water Heater Efficiencies Title Determining Benefits and Costs of Improved Water Heater Efficiencies Publication Type Report LBNL Report Number LBNL-45618 Year of Publication 2000 Authors Lekov, Alexander B., James D. Lutz, Xiaomin Liu, Camilla Dunham Whitehead, and James E. McMahon Document Number LBNL-45618 Date Published May 4 Abstract Economic impacts on individual consumers from possible revisions to U.S. residential water heater energy-efficiency standards are examined using a life-cycle cost (LCC) analysis. LCC is the consumer's cost of purchasing and installing a water heater and operating it over its lifetime. This approach makes it possible to evaluate the economic impacts on individual consumers from the revised standards. The methodology allows an examination of groups of the population which benefit or lose from suggested efficiency standards. The results show that the economic benefits to consumers are significant. At the efficiency level examined in this paper, 35% of households with electric water heaters experience LCC savings, with an average savings of $106, while 4% show LCC losses, with an average loss of $40 compared to a pre-standard LCC average of $2,565. The remainder of the population (61%) are largely unaffected.

Electric motor systems in developing countries: Opportunities for efficiency improvement  

SciTech Connect (OSTI)

This report presents an overview of the current status and efficiency improvement potential of industrial motor systems in developing countries. Better management of electric motor systems is of particular relevance in developing countries, where improved efficiency can lead to increased productivity and slower growth in electricity demand. Motor systems currently consume some 65--80% of the industrial electricity in developing countries. Drawing on studies from Thailand, India, Brazil, China, Pakistan, and Costa Rica, we describe potential efficiency gains in various parts of the motor system, from the electricity delivery system through the motor to the point where useful work is performed. We report evidence of a significant electricity conservation potential. Most of the efficiency improvement methods we examine are very cost-effective from a societal viewpoint, but are generally not implemented due to various barriers that deter their adoption. Drawing on experiences in North America, we discuss a range of policies to overcome these barriers, including education, training, minimum efficiency standards, motor efficiency testing protocols, technical assistance programs, and financial incentives.

and Natural Gas Efficiency Improvements for Residential Gas and Natural Gas Efficiency Improvements for Residential Gas Furnaces in the U.S. Title Electricity and Natural Gas Efficiency Improvements for Residential Gas Furnaces in the U.S. Publication Type Report LBNL Report Number LBNL-59745 Year of Publication 2006 Authors Lekov, Alexander B., Victor H. Franco, Stephen Meyers, James E. McMahon, Michael A. McNeil, and James D. Lutz Document Number LBNL-59745 Publisher Lawrence Berkeley National Laboratory City Berkeley Abstract This paper presents analysis of the life-cycle costs for individual households and the aggregate energy and economic impacts from potential energy efficiency improvements in U.S. residential furnaces. Most homes in the US are heated by a central furnace attached to ducts for distributing heated air and fueled by natural gas. Electricity consumption by a furnace blower is significant, comparable to the annual electricity consumption of a major appliance. Since the same blower unit is also used during the summer to circulate cooled air in centrally air conditioned homes, electricity savings occur year round. Estimates are provided of the potential electricity savings from more efficient fans and motors. Current regulations require new residential gas-fired furnaces (not including mobile home furnaces) to meet or exceed 78% annual fuel utilization efficiency (AFUE), but in fact nearly all furnaces sold are at 80% AFUE or higher. The possibilities for higher fuel efficiency fall into two groups: more efficient non-condensing furnaces (81% AFUE) and condensing furnaces (90-96% AFUE). There are also options to increase the efficiency of the furnace blower. This paper reports the projected national energy and economic impacts of requiring higher efficiency furnaces in the future. Energy savings vary with climate, with the result that condensing furnaces offer larger energy savings in colder climates. The range of impacts for a statistical sample of households and the percent of households with net savings in life cycle cost are shown. Gas furnaces are somewhat unusual in that the technology does not easily permit incremental change to the AFUE above 80%. Achieving significant energy savings requires use of condensing technology, which yields a large efficiency gain (to 90% or higher AFUE), but has a higher cost. With respect to electricity efficiency design options, the ECM has a negative effect on the average LCC. The current extra cost of this technology more than offsets the sizable electricity savings.

three-phase induction motors present a strong opportunity to reduce plant operating costs. Iff iciency Gap: Motors account for as much as 90 percent of the total electrical usage in commercial and industrial applications. Even small improvements in motor efficiency result in substantial energy savings. NOVEMBER/DECEMBER 1992 E lectric motors are among the most energy efficient devices man has ever created. Today, more efficient electric motors are available than ever before. Simple economics will justify investing in energy efficient motors for most commercial and industrial applications. Energy costs are on the rise and conservation practices- such as the use of energy efficient motors-will help control future energy costs. Conservation practices can help slow down electric load growth and offset the need to add generation capacity. Conservation can help improve productivity by using resources more efficiently and will also help to keep electric costs low. This is an age of increasing costs of electricity due mainly to higher demands for a limited resource and increasingly higher capital costs of new power plants. These and other factors have encouraged many utilities to develop conservation programs and increase energy efficiency awareness among their customers. Required generation capacity will be greater than available capacity in the U.S. by the Year 2000, according to some projections, without conservation and elec-

Increase of unit efficiency by improved waste heat recovery  

SciTech Connect (OSTI)

For coal-fired power plants with flue gas desulfurization by wet scrubbing and desulfurized exhaust gas discharge via cooling tower, a further improvement of new power plant efficiency is possible by exhaust gas heat recovery. The waste heat of exhaust gas is extracted in a flue gas cooler before the wet scrubber and recovered for combustion air and/or feedwater heating by either direct or indirect coupling of heat transfer. Different process configurations for heat recovery system are described and evaluated with regard to net unit improvement. For unite firing bituminous coal an increase of net unit efficiency of 0.25 to 0.7 percentage points and for lignite 0.7 to 1.6 percentage points can be realized depending on the process configurations of the heat recovery systems.

Improving Vehicle Efficiency, Reducing Dependence on Foreign Oil (Fact Sheet)  

SciTech Connect (OSTI)

This fact sheet provides an overview of the U.S. Department of Energy's Vehicle Technologies Program. Today, the United States spends about $400 billion each year on imported oil. To realize a secure energy future, America must break its dependence on imported oil and its volatile costs. The transportation sector accounts for about 70% of U.S. oil demand and holds tremendous opportunity to increase America's energy security by reducing oil consumption. That's why the U.S. Department of Energy (DOE) conducts research and development (R and D) on vehicle technologies which can stem America's dependence on oil, strengthen the economy, and protect the environment. Hybrid-electric and plug-in hybrid-electric vehicles can significantly improve fuel economy, displacing petroleum. Researchers are making batteries more affordable and recyclable, while enhancing battery range, performance, and life. This research supports President Obama's goal of putting 1 million electric vehicles on the road by 2015. The program is also working with businesses to develop domestic battery and electric-drive component plants to improve America's economic competitiveness globally. The program facilitates deployment of alternative fuels (ethanol, biodiesel, hydrogen, electricity, propane, and natural gas) and fuel infrastructures by partnering with state and local governments, universities, and industry. Reducing vehicle weight directly improves vehicle efficiency and fuel economy, and can potentially reduce vehicle operating costs. Cost-effective, lightweight, high-strength materials can significantly reduce vehicle weight without compromising safety. Improved combustion technologies and optimized fuel systems can improve near-and mid-term fuel economy by 25% for passenger vehicles and 20% for commercial vehicles by 2015, compared to 2009 vehicles. Reducing the use of oil-based fuels and lubricants in vehicles has more potential to improve the nation's energy security than any other action; even a 1% improvement in vehicle fuel efficiency would save consumers more than $4 billion annually.

Energy-Efficiency Improvement Opportunities for the Textile Industry  

SciTech Connect (OSTI)

The textile industry is one of the most complicated manufacturing industries because it is a fragmented and heterogeneous sector dominated by small and medium enterprises (SMEs). Energy is one of the main cost factors in the textile industry. Especially in times of high energy price volatility, improving energy efficiency should be a primary concern for textile plants. There are various energy-efficiency opportunities that exist in every textile plant, many of which are cost-effective. However, even cost-effective options often are not implemented in textile plants mostly because of limited information on how to implement energy-efficiency measures, especially given the fact that a majority of textile plants are categorized as SMEs and hence they have limited resources to acquire this information. Know-how on energy-efficiency technologies and practices should, therefore, be prepared and disseminated to textile plants. This guidebook provides information on energy-efficiency technologies and measures applicable to the textile industry. The guidebook includes case studies from textile plants around the world and includes energy savings and cost information when available. First, the guidebook gives a brief overview of the textile industry around the world, with an explanation of major textile processes. An analysis of the type and the share of energy used in different textile processes is also included in the guidebook. Subsequently, energy-efficiency improvement opportunities available within some of the major textile sub-sectors are given with a brief explanation of each measure. The conclusion includes a short section dedicated to highlighting a few emerging technologies in the textile industry as well as the potential for the use of renewable energy in the textile industry.

Technologies and Policies to Improve Energy Efficiency in Industry  

Science Journals Connector (OSTI)

The industrial sector consumes nearly 40% of annual global primary energy use and is responsible for a similar share of global energy?related carbon dioxide ( CO 2 ) emissions. Many studies and actual experience indicate that there is considerable potential to reduce the amount of energy used to manufacture most commodities concurrently reducing CO 2 emissions. With the support of strong policies and programs energy?efficient technologies and measures can be implemented that will reduce global CO 2 emissions. A number of countries including the Netherlands the UK and China have experience implementing aggressive programs to improve energy efficiency and reduce related CO 2 emissions from industry. Even so there is no silver bullet and all options must be pursued if greenhouse gas emissions are to be constrained to the level required to avoid significant negative impacts from global climate change.

Sathaye, Ali Hasanbeigi, and Tengfang T. Xu Date Published 06/2013 Publisher Lawrence Berkeley National Laboratory City Berkeley Keywords industrial energy efficiency Abstract Adoption of efficient process technologies is an important approach to reducing CO2 emissions, in particular those associated with combustion. In many cases, implementing energy efficiency measures is among the most cost-effective approaches that any refiner can take, improving productivity while reducing emissions. Therefore, careful analysis of the options and costs associated with efficiency measures is required to establish sound carbon policies addressing global climate change, and is the primary focus of LBNL's current petroleum refining sector analysis for the U.S. Environmental Protection Agency. The analysis is aimed at identifying energy efficiency-related measures and developing energy abatement supply curves and CO2 emissions reduction potential for the U.S. refining industry. A refinery model has been developed for this purpose that is a notional aggregation of the U.S. petroleum refining sector. It consists of twelve processing units and accounts for the additional energy requirements from steam generation, hydrogen production and water utilities required by each of the twelve processing units. The model is carbon and energy balanced such that crude oil inputs and major refinery sector outputs (fuels) are benchmarked to 2010 data. Estimates of the current penetration for the identified energy efficiency measures benchmark the energy requirements to those reported in U.S. DOE 2010 data. The remaining energy efficiency potential for each of the measures is estimated and compared to U.S. DOE fuel prices resulting in estimates of cost-effective energy efficiency opportunities for each of the twelve major processes. A combined cost of conserved energy supply curve is also presented along with the CO2 emissions abatement opportunities that exist in the U.S. petroleum refinery sector. Roughly 1,200 PJ per year of primary fuels savings and close to 500 GWh per year of electricity savings are potentially cost-effective given U.S. DOE fuel price forecasts. This represents roughly 70 million metric tonnes of CO2 emission reductions assuming 2010 emissions factor for grid electricity. Energy efficiency measures resulting in an additional 400 PJ per year of primary fuels savings and close to 1,700 GWh per year of electricity savings, and an associated 24 million metric tonnes of CO2 emission reductions are not cost-effective given the same assumption with respect to fuel prices and electricity emissions factors. Compared to the modeled energy requirements for the U.S. petroleum refining sector, the cost effective potential represents a 40% reduction in fuel consumption and a 2% reduction in electricity consumption. The non-cost-effective potential represents an additional 13% reduction in fuel consumption and an additional 7% reduction in electricity consumption. The relative energy reduction potentials are much higher for fuel consumption than electricity consumption largely in part because fuel is the primary energy consumption type in the refineries. Moreover, many cost effective fuel savings measures would increase electricity consumption.

Improving computational efficiency of Monte Carlo simulations with variance reduction  

SciTech Connect (OSTI)

CCFE perform Monte-Carlo transport simulations on large and complex tokamak models such as ITER. Such simulations are challenging since streaming and deep penetration effects are equally important. In order to make such simulations tractable, both variance reduction (VR) techniques and parallel computing are used. It has been found that the application of VR techniques in such models significantly reduces the efficiency of parallel computation due to 'long histories'. VR in MCNP can be accomplished using energy-dependent weight windows. The weight window represents an 'average behaviour' of particles, and large deviations in the arriving weight of a particle give rise to extreme amounts of splitting being performed and a long history. When running on parallel clusters, a long history can have a detrimental effect on the parallel efficiency - if one process is computing the long history, the other CPUs complete their batch of histories and wait idle. Furthermore some long histories have been found to be effectively intractable. To combat this effect, CCFE has developed an adaptation of MCNP which dynamically adjusts the WW where a large weight deviation is encountered. The method effectively 'de-optimises' the WW, reducing the VR performance but this is offset by a significant increase in parallel efficiency. Testing with a simple geometry has shown the method does not bias the result. This 'long history method' has enabled CCFE to significantly improve the performance of MCNP calculations for ITER on parallel clusters, and will be beneficial for any geometry combining streaming and deep penetration effects.

Improving the energy efficiency of refrigerators in India  

SciTech Connect (OSTI)

Five state-of-the-art, production refrigerators from different manufacturers in India were subjected to a variety of appliance rating and performance evaluation test procedures in an engineering laboratory. Cabinet heat loss, compressor calorimeter, high-ambient pull-down, and closed-door energy consumption tests were performed on each unit to assess the current status of commercially available Indian refrigerators and refrigerator component efficiencies. Daily energy consumption tests were performed at nominal line voltages and at 85% and 115% of nominal voltage to assess the effect of grid voltage variations. These test results were also used to indicate opportunities for effective improvements in energy efficiency. A widely distributed ``generic`` computer model capable of simulating single-door refrigerators with a small interior freezer section was used to estimate cabinet heat loss rates and closed door energy consumption values from basic cabinet and refrigeration circuit inputs. This work helped verify the model`s accuracy and potential value as a tool for evaluating the energy impact of proposed design options. Significant differences ranging from 30 to 90% were seen in the measured performance criterion for these ``comparable`` refrigerators suggesting opportunities for improvements in individual product designs. Modeled cabinet heat loadings differed from experimentally extrapolated values in a range from 2--29%, and daily energy consumption values estimated by the model differed from laboratory data by as little as 3% or as much as 25%, which indicates that refinement of the model may be needed for this single-door refrigerator type. Additional comparisons of experimentally measured performance criteria such as % compressor run times and compressor cycling rates to modeled results are given. The computer model is used to evaluate the energy saving impact of several modest changes to the basic Indian refrigerator design.

Improving the efficiency of electric motor systems: Moving beyond efficient motors  

SciTech Connect (OSTI)

Electric motors operating in the US consume more than half of the nation's electricity. Electric utilities were among the first groups to begin offering programs to promote efficiency in electric motors. A 1994 Electric Power Research Institute (EPRI) survey of utility demand-side management (DSM) programs found 151 efficient-motors and drives programs being offered by 95 utilities in the US. The most common programs have been prescriptive rebates for the purchase of high-efficiency motors. While many of these programs have been popular and successful, their cost is an issue of contention with some industrial consumer groups and within utilities attempting to reduce program costs. With the minimum motor efficiency regulations in the Energy Policy Act of 1992 (EPAct) set to go into effect for most products in October 1997, utilities will need to move beyond these simple high-efficiency motor rebate programs if they are to continue to offer motor programs to their customers. The focus will also have to shift from simply motors to motor-system issues. As a 1993 US Department of Energy (DOE)-sponsored motor-system roundtable identified, motor-system expertise is not widely available, and many electric utilities will need assistance to develop and implement new programs. It is thus important that information be made available to these utilities on how to analyze customers' motor-systems needs, what program designs will most likely meet these needs, what resources they will need to implement their programs, and where to find those resources. DOE's Motor Challenge has already been identifying or developing many of these resources, and these are already being used by some utilities. If utilities are provided a program context, more of them can make better use of these resources and achieve success from their own standpoint (e.g., increased customer satisfaction and improved customer retention), from the customers' standpoint (e.g., lower motor-system costs and improved performance), and from the national standpoint (e.g., reduced motorsystem energy consumption and lower carbon emissions). The American Council for an Energy-Efficient Economy (ACEEE) has begun to establish this context by analyzing utility motor-systems programs. This work builds upon past ACEEE analyses of other utility DSM programs and ACEEE's extensive involvement in the technical aspects and design of programs involving electric motor systems.

CERAMIC MEMBRANE ENABLING TECHNOLOGY FOR IMPROVED IGCC EFFICIENCY  

SciTech Connect (OSTI)

The objective of this program is to conduct a technology development program to advance the state-of-the-art in ceramic Oxygen Transport Membranes (OTM) to the level required to produce step change improvements in process economics, efficiency, and environmental benefits for commercial IGCC systems and other applications. The IGCC program is focused on addressing key issues in materials, processing, manufacturing, engineering and system development that will make the OTM a commercial reality. The objective of the OTM materials development task is to identify a suitable material that can be formed into a thin film to produce the target oxygen flux. This requires that the material have an adequate permeation rate, and thermo-mechanical and thermo-chemical properties such that the material is able to be supported on the desired substrate and sufficient mechanical strength to survive the stresses involved in operation. The objective of the composite OTM development task is to develop the architecture and fabrication techniques necessary to construct stable, high performance, thin film OTMs supported on suitable porous, load bearing substrates. The objective of the process development task of this program to demonstrate the program objectives on a single OTM tube under test conditions simulating those of the optimum process cycle for the power plant. Good progress has been made towards achieving the DOE-IGCC program objectives. Two promising candidates for OTM materials have been identified and extensive characterization will continue. New compositions are being produced and tested which will determine if the material can be further improved in terms of flux, thermo-mechanical and thermo-chemical properties. Process protocols for the composite OTM development of high quality films on porous supports continues to be optimized. Dense and uniform PSO1 films were successfully applied on porous disc and tubular substrates with good bonding between the films and substrates, and no damage to the substrates or films.

A Retrofit Tool for Improving Energy Efficiency of Commercial Buildings  

SciTech Connect (OSTI)

Existing buildings will dominate energy use in commercial buildings in the United States for three decades or longer and even in China for the about two decades. Retrofitting these buildings to improve energy efficiency and reduce energy use is thus critical to achieving the target of reducing energy use in the buildings sector. However there are few evaluation tools that can quickly identify and evaluate energy savings and cost effectiveness of energy conservation measures (ECMs) for retrofits, especially for buildings in China. This paper discusses methods used to develop such a tool and demonstrates an application of the tool for a retrofit analysis. The tool builds on a building performance database with pre-calculated energy consumption of ECMs for selected commercial prototype buildings using the EnergyPlus program. The tool allows users to evaluate individual ECMs or a package of ECMs. It covers building envelope, lighting and daylighting, HVAC, plug loads, service hot water, and renewable energy. The prototype building can be customized to represent an actual building with some limitations. Energy consumption from utility bills can be entered into the tool to compare and calibrate the energy use of the prototype building. The tool currently can evaluate energy savings and payback of ECMs for shopping malls in China. We have used the tool to assess energy and cost savings for retrofit of the prototype shopping mall in Shanghai. Future work on the tool will simplify its use and expand it to cover other commercial building types and other countries.

IMPROVING CO2 EFFICIENCY FOR RECOVERING OIL IN HETEROGENEOUS RESERVOIRS  

SciTech Connect (OSTI)

The third annual report of ''Improving CO{sub 2} Efficiency for Recovery Oil in Heterogeneous Reservoirs'' presents results of laboratory studies with related analytical models for improved oil recovery. All studies were designed to optimize utilization and extend the practice of CO{sub 2} flooding to a wider range of reservoirs. Chapter 1 describes the behavior at low concentrations of the surfactant Chaser International CD1045{trademark} (CD) versus different salinity, pressure and temperature. Results of studies on the effects of pH and polymer (hydrolyzed polyacrylamide?HPAM) and CO{sub 2} foam stability after adsorption in the core are also reported. Calcium lignosulfonate (CLS) transport mechanisms through sandstone, description of the adsorption of CD and CD/CLS onto three porous media (sandstone, limestone and dolomite) and five minerals, and the effect of adsorption on foam stability are also reported. In Chapter 2, the adsorption kinetics of CLS in porous Berea sandstone and non-porous minerals are compared by monitoring adsorption density change with time. Results show that adsorption requires a much longer time for the porous versus non-porous medium. CLS adsorption onto sandstone can be divided into three regions: adsorption controlled by dispersion, adsorption controlled by diffusion and adsorption equilibrium. NaI tracer used to characterize the sandstone had similar trends to earlier results for the CLS desorption process, suggesting a dual porosity model to simulate flow through Berea sandstone. The kinetics and equilibrium test for CD adsorption onto five non-porous minerals and three porous media are reported in Chapter 3. CD adsorption and desorption onto non-porous minerals can be established in less than one hour with adsorption densities ranging from 0.4 to 1.2 mg of CD per g of mineral in decreasing order of montmorillonite, dolomite, kaolinite, silica and calcite. The surfactant adsorption onto three porous media takes much longer than one hour, with Berea sandstone requiring the longest time. In Chapter 4, comparisons of static adsorption of CLS, CD, and CLS/CD mixtures onto five pure minerals showed that the presence of CLS decreased the adsorption of CD onto the five minerals by 20 to 70%. Dynamic CLS/CD mixture adsorption tests onto Berea sandstone and Indian limestone cores showed that competitive adsorption between CD and CLS generally takes several days to reach equilibrium. Foam stability and interfacial tension tests on both injected and effluent samples were performed which showed that both foam stability and IFT decreased due to adsorption. Also it appears that there is a chromatographic effect on the surfactants in flow through porous media. Progress was realized in developing general equations for stress sensitivity on non-Darcy parameters (permeability and non-Darcy coefficient), and the multiphase flow induced by a high flow rate was confirmed as a mechanism for injectivity loss in CO{sub 2} flooding. In Chapter 5, a general equation is defined based on 60 general equations of permeability stress sensitivity and non-Darcy coefficient stress sensitivity and definitions of nominal permeability, nominal non-Darcy coefficient, permeability stress sensitivity, and non-Darcy coefficient stress sensitivity. The equations of stress sensitivity are independent of pressure, temperature, and rock properties and existing empirical correlations of the nominal permeability and nominal non-Darcy coefficient can be used when laboratory data are not available. This provides a tool to quantify the change of permeability and non-Darcy coefficient due to change of effective stress resulted from reservoir injection and/or production.

The laws of thermodynamics apply equally well to quantum systems as to classical systems, and because of this quantum effects do not change the fundamental thermodynamic efficiency of isothermal refrigerators or engines. We show that, despite this fact, quantum mechanics permits measurement-based feedback control protocols that are more thermodynamically efficient than their classical counterparts. As part of our analysis we perform a detailed accounting of the thermodynamics of unitary feedback control, and elucidate the sources of inefficiency in measurement-based and coherent feedback.

Policies for eliminating low-efficiency production capacities and improving energy efficiency of energy-intensive industries in China  

Science Journals Connector (OSTI)

Abstract China faced the greatest challenge in balancing its economic growth, energy and resource security as well as environmental pollution. The energy-intensive industries, which used to be the major force driving China?s economic growth, had seriously exhausted the countries? natural resources and energy, and at the same time polluted the environment because of the severe surplus of low-efficiency production capacities. As a result, the Chinese government had initiated multiple economic and administrative policies to eliminate these low-efficiency production capacities intended to improve the energy efficiency of energy-intensive industries. These policies are summarized in this paper, along with export tax rebating rate, resource tax, administrative audit and approvals, differential electric power pricing and shutting down the low-efficiency production capacities. The paper also evaluates the effects of these policies by analyzing several key indicators about the energy-intensive industries, including fixed asset investment growth rate, energy-intensity of industrial added-value, waste gas emission-intensity of industrial added-value. The VALDEX methodology is selected to examine the improving trends of energy-efficiency for energy-intensive industries. The analyzing results show that firstly the development of low-efficiency capacities tends to be more sensitive to the policies, so the policies that China had enacted really exert very important effects on improving the energy-efficiency of energy-intensive industries. However, the effects of economic policies seem more faster and obvious than the fiscal policies. Besides, the results also show that polices which are designed to reserve energy may not necessarily exert the same effects on reducing emissions. There is still large room for improving the energy efficiency of energy-intensive industries, substantial improvement still needs to be done for current policies system. Some suggestions for future work are provided.

SciTech Connect (OSTI)

A multi-optical fiber technique is presented, which enables one to detect the flame propagation during non-knocking and knocking conditions in real production engines. The measurement technique is appropriate to detect knock onset locations and to describe the propagation of knocking reaction fronts. With this knowledge, the combustion chamber shape can be optimized, leading to a better knock resistance and higher combustion efficiencies. Results of flame propagation under non-knocking and knocking engine operating conditions are presented. In addition, correlations between knock onset locations and areas in which knock damage occurs are shown for different engines. Presented are the effects of combustion chamber modifications on the combustion efficiency, based on the analysis of the optical fiber measurements.

Efficiency improvement of silicon nanostructure-based solar cells  

Science Journals Connector (OSTI)

Solar cells based on a high-efficiency silicon nanostructure (SNS) were developed using a two-step metal-assisted electroless etching (MAEE) technique, phosphorus silicate glass (PSG) doping and screen printing. This process was used to produce solar cells with a silver nitrate (AgNO3) etching solution in different concentrations. Compared to cells produced using the single MAEE technique, SNS-based solar cells produced with the two-step MAEE technique showed an increase in silicon surface coverage of ~181.1% and a decrease in reflectivity of ~144.3%. The performance of the SNS-based solar cells was found to be optimized (~11.86%) in an SNS with a length of ~300nm, an aspect ratio of ~5, surface coverage of ~84.9% and a reflectivity of ~6.1%. The ~16.8% increase in power conversion efficiency (PCE) for the SNS-based solar cell indicates good potential for mass production.

FORSCOM installation characterization and ranking for water efficiency improvement  

SciTech Connect (OSTI)

On March 11, 1994, President Clinton signed Executive Order 12902-Energy Efficiency and Water Conservation at Federal Facilities. Section 302 of the Executive Order calls for energy and water prioritization surveys of federal facilities to be conducted. The surveys will be used to establish priorities for conducting comprehensive facility audits. In response to the requirements of the Executive Order, the U.S. Army Forces Command (FORSCOM) has tasked Pacific Northwest Laboratory (PNL) to initiate a broad study of the water savings potential at each of its major installations. This report provides an assessment of the water, sewer, energy (for hot water production and pumping), and associated cost savings potential at ten of the major FORSCOM installations. This assessment is meant to be a {open_quotes}first pass{close_quotes} estimate of the water savings potential, to assist FORSCOM in prioritizing installations for detailed water audits and potential water efficient retrofits. In addition, the end uses (toilets, sinks, showerheads, irrigation, etc.) with the greatest water savings potential are identified at each installation. This report is organized in the following manner. Following this Introduction, Section 2 provides important background information pertaining to the water analysis. Section 3 describes the methodology employed in the analysis, and Section 4 summarizes the study results. Section 5 prioritizes the installations based on both water/sewer savings and cost associated with water, sewer, and energy savings. Section 6 provides recommendations on where to start detailed water audits, as well as other recommendations. References are listed in Section 7. The appendices provide specific information on the analysis results and methodology, along with a discussion of special issues.

Output, efficiency, emissions improved with Cat's 3500 series B engine  

SciTech Connect (OSTI)

Like most technologies, engine developments tend to follow evolutionary paths. And it's a given that the longer an engine's been around and the more successful it's been, the more likely it is that any changes made would be incremental. On the surface, such is the case with the Caterpillar 3500 Series B diesel engine, recently introduced in Europe and the United States. Based on the well-proven 3500 engine first introduced in 1980 and upgraded with a Phase II program five years later, most of the changes appear incremental. But taken as a whole, they provide a level of performance and durability that Caterpillar anticipates will make this engine an even stronger contender in power generation and marine applications for years to come. It's not hard to see why. Output has been increased between 17% and 30% on some models; fuel consumption is improved by as much as 15%; and with the new aftertreatment system introduced with the engines, emissions as low as 1.3 g/kWh NO[sub x] are said to be achieveable. This paper outlines the design, specifications, and highlights of the improvements in performance of these new engines. 3 figs.

Adjustable Nonlinear Springs to Improve Efficiency of Vibration Energy Harvesters  

E-Print Network [OSTI]

Vibration Energy Harvesting is an emerging technology aimed at turning mechanical energy from vibrations into electricity to power microsystems of the future. Most of present vibration energy harvesters are based on a mass spring structure introducing a resonance phenomenon that allows to increase the output power compared to non-resonant systems, but limits the working frequency bandwidth. Therefore, they are not able to harvest energy when ambient vibrations' frequencies shift. To follow shifts of ambient vibration frequencies and to increase the frequency band where energy can be harvested, one solution consists in using nonlinear springs. We present in this paper a model of adjustable nonlinear springs (H-shaped springs) and their benefits to improve velocity-damped vibration energy harvesters' (VEH) output powers. A simulation on a real vibration source proves that the output power can be higher in nonlinear devices compared to linear systems (up to +48%).

Mechanistic Understanding of Microbial Plugging for Improved Sweep Efficiency  

SciTech Connect (OSTI)

Microbial plugging has been proposed as an effective low cost method of permeability reduction. Yet there is a dearth of information on the fundamental processes of microbial growth in porous media, and there are no suitable data to model the process of microbial plugging as it relates to sweep efficiency. To optimize the field implementation, better mechanistic and volumetric understanding of biofilm growth within a porous medium is needed. In particular, the engineering design hinges upon a quantitative relationship between amount of nutrient consumption, amount of growth, and degree of permeability reduction. In this project experiments were conducted to obtain new data to elucidate this relationship. Experiments in heterogeneous (layered) beadpacks showed that microbes could grow preferentially in the high permeability layer. Ultimately this caused flow to be equally divided between high and low permeability layers, precisely the behavior needed for MEOR. Remarkably, classical models of microbial nutrient uptake in batch experiments do not explain the nutrient consumption by the same microbes in flow experiments. We propose a simple extension of classical kinetics to account for the self-limiting consumption of nutrient observed in our experiments, and we outline a modeling approach based on architecture and behavior of biofilms. Such a model would account for the changing trend of nutrient consumption by bacteria with the increasing biomass and the onset of biofilm formation. However no existing model can explain the microbial preference for growth in high permeability regions, nor is there any obvious extension of the model for this observation. An attractive conjecture is that quorum sensing is involved in the heterogeneous bead packs.

Energy Efficiency Improvement Opportunities for the Cement Industry  

SciTech Connect (OSTI)

This report provides information on the energy savings, costs, and carbon dioxide emissions reductions associated with implementation of a number of technologies and measures applicable to the cement industry. The technologies and measures include both state-of-the-art measures that are currently in use in cement enterprises worldwide as well as advanced measures that are either only in limited use or are near commercialization. This report focuses mainly on retrofit measures using commercially available technologies, but many of these technologies are applicable for new plants as well. Where possible, for each technology or measure, costs and energy savings per tonne of cement produced are estimated and then carbon dioxide emissions reductions are calculated based on the fuels used at the process step to which the technology or measure is applied. The analysis of cement kiln energy-efficiency opportunities is divided into technologies and measures that are applicable to the different stages of production and various kiln types used in China: raw materials (and fuel) preparation; clinker making (applicable to all kilns, rotary kilns only, vertical shaft kilns only); and finish grinding; as well as plant wide measures and product and feedstock changes that will reduce energy consumption for clinker making. Table 1 lists all measures in this report by process to which they apply, including plant wide measures and product or feedstock changes. Tables 2 through 8 provide the following information for each technology: fuel and electricity savings per tonne of cement; annual operating and capital costs per tonne of cement or estimated payback period; and, carbon dioxide emissions reductions for each measure applied to the production of cement.

Final Scientific Report - "Improved Fuel Efficiency from Nanocomposite Tire Tread"  

SciTech Connect (OSTI)

Rolling resistance, a measure of the energy lost as a tire rotates while moving, is a significant source of power and fuel loss. Recently, low rolling resistant tires have been formulated by adding silica to tire tread. These "Green Tires" (so named from the environmental advantages of lower emissions and improved fuel economy) have seen some commercial success in Europe, where high fuel prices and performance drive tire selection. Unfortunately, the higher costs of the silica and a more complicated manufacturing process have prevented significant commercialization - and the resulting fuel savings - in the U.S. In this project, TDA Research, Inc. (TDA) prepared an inexpensive alternative to silica that leads to tire components with lower rolling resistance. These new tire composite materials were processed with traditional rubber processing equipment. We prepared specially designed nanoparticle additives, based on a high purity, inorganic mineral whose surface can be easily modified for compatibility with tire tread formulations. Our nanocomposites decreased energy losses to hysteresis, the loss of energy from the compression and relaxation of an elastic material, by nearly 20% compared to a blank SBR sample. We also demonstrated better performance than a leading silica product, with easier production of our final rubber nanocomposite.

Dragload analysis: A unique method of improving paper machine efficiency  

SciTech Connect (OSTI)

Dragload is the force required to drive a forming fabric while the sheet is being dewatered. The suggested method for calculating dragload and component dragload uses the relationship between fabric velocity and tension and the mechanical properties of the fabric. The advantage of this method over more conventional methods is its ability to be used on any type of machine or drive system and, most importantly, its ability to localize specific areas of dragload (component dragload) without the need to interrupt production on the machine. The method's limitation is that it does not produce an exact result, only an approximation. Obtaining the exact fabric velocity is difficult; however, there is enough accuracy in the readings with which to diagnose and troubleshoot. Steps taken to reduce dragload will help decrease energy consumption and increase forming fabric life. The suggested method provides a readily visible means of determining areas of high dragload. If used, this method will provide a valuable tool for further cost improvement in the papermaking process.

Steam Pressure-Reducing Station Safety and Energy Efficiency Improvement Project  

SciTech Connect (OSTI)

The Facilities and Operations (F&O) Directorate is sponsoring a continuous process improvement (CPI) program. Its purpose is to stimulate, promote, and sustain a culture of improvement throughout all levels of the organization. The CPI program ensures that a scientific and repeatable process exists for improving the delivery of F&O products and services in support of Oak Ridge National Laboratory (ORNL) Management Systems. Strategic objectives of the CPI program include achieving excellence in laboratory operations in the areas of safety, health, and the environment. Identifying and promoting opportunities for achieving the following critical outcomes are important business goals of the CPI program: improved safety performance; process focused on consumer needs; modern and secure campus; flexibility to respond to changing laboratory needs; bench strength for the future; and elimination of legacy issues. The Steam Pressure-Reducing Station (SPRS) Safety and Energy Efficiency Improvement Project, which is under the CPI program, focuses on maintaining and upgrading SPRSs that are part of the ORNL steam distribution network. This steam pipe network transports steam produced at the ORNL steam plant to many buildings in the main campus site. The SPRS Safety and Energy Efficiency Improvement Project promotes excellence in laboratory operations by (1) improving personnel safety, (2) decreasing fuel consumption through improved steam system energy efficiency, and (3) achieving compliance with applicable worker health and safety requirements. The SPRS Safety and Energy Efficiency Improvement Project being performed by F&O is helping ORNL improve both energy efficiency and worker safety by modifying, maintaining, and repairing SPRSs. Since work began in 2006, numerous energy-wasting steam leaks have been eliminated, heat losses from uninsulated steam pipe surfaces have been reduced, and deficient pressure retaining components have been replaced. These improvements helped ORNL reduce its overall utility costs by decreasing the amount of fuel used to generate steam. Reduced fuel consumption also decreased air emissions. These improvements also helped lower the risk of burn injuries to workers and helped prevent shrapnel injuries resulting from missiles produced by pressurized component failures. In most cases, the economic benefit and cost effectiveness of the SPRS Safety and Energy Efficiency Improvement Project is reflected in payback periods of 1 year or less.

Opportunities for improving leaf water use efficiency under climate change conditions  

Science Journals Connector (OSTI)

Abstract \\{WUEi\\} (intrinsic water use efficiency) is a complex (multi)-trait, that depends on several physiological processes, driving plant productivity and its relation with a changing environment. Climatic change predictions estimate increases in temperature and drought in the semi-arid regions, rendering improved water use efficiency is a mandatory objective to maintain the current global food supply. The aims of this review were (i) to identify through a meta-analysis the leaf traits mostly related to intrinsic water use efficiency (WUEi, the ratio between A net photosynthesis and gs stomatal conductance), based on a newly compiled dataset covering more than 200 species/varieties and 106 genus of C3 plants (ii) to describe the main potential targets for \\{WUEi\\} improvement via biotechnological manipulations and (iii) to introduce emergent and innovative technologies including \\{UAVs\\} (Unmanned Aerial Vehicles) to scale up levels from leaf to whole plant water status. We confirmed that increases in gm/gs and Vcmax/gs ratios are systematically related with increases in \\{WUEi\\} maintained across species, habitats, and environmental conditions. Other emergent opportunities to improve \\{WUEi\\} are described such as the relationship between photosynthesis and respiration and their link with metabolomics. Finally, we outline our hypothesis that we are observing the advent of a smart agriculture, wherein new technologies, such as \\{UAVs\\} equipped with remote sensors will rapidly facilitate an efficient water use regulating the irrigation schedule and determination, under field conditions, of cultivars with improved water use efficiency. We, therefore, conclude that the multi-disciplinary challenge toward WUE has only just begun.

Heating boilers in Krakow, Poland: Options for improving efficiency and reducing emissions  

SciTech Connect (OSTI)

In Krakow, Poland, coal-fired boilers are used to heat single apartment buildings and local heating districts. Tile population includes 2,930 small, hand-fired boilers and 227 larger traveling grate stoker-fired boilers. These boilers are important contributors to air quality problems in Krakow, and an assessment of their efficiency and emissions characteristics was recently undertaken. For the larger, stoker-fired boilers, efficiency was measured using a stack-loss method In addition to the normal baseline fuel, the effects of coal cleaning and grading were evaluated Testing was done at two selected sites. Boiler efficiencies were found to be low-50% to 67%. These boilers operate without combustion controls or instrumentation for flue gas analysis. As a result, excess air levels are very high (up to 400%) leading to poor performance. Emissions were found to be typical for boilers of this type. Using the improved fuels yields reductions in emissions and improvement in efficiency when combined with proper adjustments. In the case of the hand-fired boilers, one set of cast-iron boilers and one set of steel boilers were tested. Efficiency in this case was measured using an input-output method for sets of three boilers taken together as a system. Emissions from these boilers are lowest when low volatile fuels, such as coke or smokeless briquettes, are used.

Increasing innovation in home energy efficiency: Monte Carlo simulation of potential improvements  

Science Journals Connector (OSTI)

Despite the enormous potential for savings, there is little penetration of market-based solutions in the residential energy efficiency market. We hypothesize that there is a failure in the residential efficiency improvement market: due to lack of customer knowledge and capital to invest in improvements, there is unrecovered savings. In this paper, we model a means of extracting profit from those unrecovered energy savings with a market-based residential energy services company, or RESCO. We use a Monte Carlo simulation of the cost and performance of various improvements along with a hypothetical business model to derive general information about the financial viability of these companies. Despite the large amount of energy savings potential, we find that an average contract length with residential customers needs to be nearly 35 years to recoup the cost of the improvements. However, our modeling of an installer knowledge parameter indicates that experience plays a large part in minimizing the time to profitability for each home. Large numbers of inexperienced workers driven by government investment in this area could result in the installation of improvements with long payback periods, whereas a free market might eliminate companies making poor decisions.

A Study on Energy Efficiency Improvement Opportunities for Plug Loads in Buildings in the Equatorial Region  

Science Journals Connector (OSTI)

Abstract The small plug loads in the tropical buildings are among the fastest growing sources of energy use. Yet, there are comparatively fewer studies that were focused on the energy efficiency improvement potentials of the office equipment due to its elusive, more diversified and sophisticated nature. This objective of this study is to identify the opportunity for energy efficiency improvement of the frequently used office equipment in a commercial building in Malaysia, by focusing on the occupant behaviour and software power management features. The outcomes show that about 19% of the total energy demand can be reduced if the office equipment not in use are turned off, unplugged or disconnected. This also led to a significant reduction in greenhouse gases emission. This finding is particularly important for good energy demand management, as more and more modern electric appliances are introduced into the local commercial buildings which are contributing to the increase in energy consumption and subsequently, the electric bill.

SciTech Connect (OSTI)

Considerable research has focused on energy efficiency and fuel substitution options for light-duty vehicles, while much less attention has been given to medium- and heavy-duty trucks, buses, aircraft, marine vessels, trains, pipeline, and off-road equipment. This report brings together the salient findings from an extensive review of literature on future energy efficiency options for these non-light-duty modes. Projected activity increases to 2050 are combined with forecasts of overall fuel efficiency improvement potential to estimate the future total petroleum and greenhouse gas (GHG) emissions relative to current levels. This is one of a series of reports produced as a result of the Transportation Energy Futures (TEF) project, a Department of Energy-sponsored multi-agency project initiated to pinpoint underexplored strategies for abating GHGs and reducing petroleum dependence related to transportation.

Improving Energy Efficiency and Enabling Water Recycle in Biorefineries Using Bioelectrochemical Cells.  

SciTech Connect (OSTI)

Improving biofuel yield and water reuse are two important issues in further development of biorefineries. The total energy content of liquid fuels (including ethanol and hydrocarbon) produced from cellulosic biomass via biochemical or hybrid bio-thermochemical routes can vary from 49% to 70% of the biomass entering the biorefinery, on an energy basis. Use of boiler for combustion of residual organics and lignin results in significant energy and water losses. An alternate process to improve energy recovery from the residual organic streams is via use of bioelectrochemical systems such as microbial fuel cells (MFCs) microbial electrolysis cells (MECs). The potential advantages of this alternative scheme in a biorefinery include minimization of heat loss and generation of a higher value product, hydrogen. The need for 5-15 gallons of water per gallon of ethanol can be reduced significantly via recycle of water after MEC treatment. Removal of inhibitory byproducts such as furans, phenolics and acetate in MFC/MECs to generate energy, thus, has dual advantages including improvements in energy efficiency and ability to recycle water. Conversion of the sugar- and lignin- degradation products to hydrogen is synergistic with biorefinery hydrogen requirements for upgrading F-T liquids and other byproducts to high-octane fuels and/or high value products. Some of these products include sorbitol, succinic acid, furan and levulinate derivatives, glycols, polyols, 1,4-butenadiol, phenolics polymers, etc. Potential process alternatives utilizing MECs in biorefineries capable of improving energy efficiency by up to 30% are discussed.

Study of Improvement in Boiler Efficiency through Incorporation of Additional Bank of Tubes in the Economiser  

E-Print Network [OSTI]

Abstract: The major efficiency loss of a boiler is caused by the hot stack gases discharging to the atmosphere which is polluting the atmosphere and on other side Pollution Control Board is forcing the norms of Pollution levels in atmosphere. One of the most cost-effective ways of improving the efficiency of a high pressure steam boiler is to install an economizer on the boiler. An economizer is a heat exchanger, which transfers heat from the stack gases to the incoming feedwater. Typically, on a high pressure water tube boiler, the efficiency improvement with an economizer is 2 to 4%, depending on firing rate. On a high pressure fire tube boiler, the improvement is 2 to 3.5%, depending on boiler size and firing rate. The economizers are located in the boiler stack close to the stack gas outlet of the boiler. They may be supported from overhead or from the floor. A feedwater line, which serves the boiler, is piped to the unit. No additional feedwater control valves or stack gas dampers are required. Presently in NTPC stage II units there are banks of tubes in economizer. There was a proposal from management to add another bank of tubes in the economizer so that there will be control of pollutants coming out from boiler. We took that proposal as a task and made a detailed investigation of it. An investigation is conducted on the effect of performance of the boiler by incorporating the additional bank of tubes in the space below the lower bank of tubes. The main idea is to extract maximum amount of heat from the flue gases and increase the heat

Customer system efficiency improvement assessment: Supply curves for transmission and distribution conservation options  

SciTech Connect (OSTI)

This report documents the results of Task 6 in the Customer System Efficiency Improvement (CSEI) Assessment Project. A principal objective of this project is to assess the potential for energy conservation in the transmission and distribution (TandD) systems of electric utilities in the BPA service area. The scope of this assessment covers BPA customers in the Pacific Northwest region and all non-federal TandD systems, including those that currently place no load on the BPA system. Supply curves were developed to describe the conservation resource potentially available from TandD-system efficiency improvements. These supply curves relate the levelized cost of upgrading existing equipment to the estimated amount of energy saved. Stated in this form, the resource represented by TandD loss reductions can be compared with other conservation options and regional electrical generation resources to determine the most cost-effective method of supplying power to the Pacific Northwest. The development of the supply curves required data acquisition and methodology development that are also described in this report. 11 refs., 11 figs., 16 tabs.

Mathematical description for the measurement and verification of energy efficiency improvement  

Science Journals Connector (OSTI)

Abstract Insufficient energy supply is a problem faced by many countries, and energy efficiency improvement is identified as the quickest and most effective solution to this problem. Many energy efficiency projects are therefore initiated to reach various energy saving targets. These energy saving targets need to be measured and verified, and in many countries such a measurement and verification (M&V) activity is guided by the International Performance Measurement and Verification Protocol (IPMVP). However, M&V is widely regarded as an inaccurate science: an engineering practice relying heavily on professional judgement. This paper presents a mathematical description of the energy efficiency M&V problem and thus casts into a scientific framework the basic M&V concepts, propositions, techniques and methodologies. For this purpose, a general description of energy system modeling is provided to facilitate the discussion, strict mathematical definitions for baseline and baseline adjustment are given, and the M&V plan development is formulated as an M&V modeling problem. An optimal M&V plan is therefore obtained through solving a calculus of variation, or equivalently, an optimal control problem. This approach provides a fruitful source of research problems by which optimal M&V plans under various practical constraints can be determined. With the aid of linear control system models, this mathematical description also provides sufficient conditions for M&V practitioners to determine which one of the four M&V options in IPMVP should be used in a practical M&V project.

Energy Efficiency Improvement and Cost Saving Oportunities for the Concrete Industry  

SciTech Connect (OSTI)

The U.S. concrete industry is the main consumer of U.S.-produced cement. The manufacturing of ready mixed concrete accounts for more than 75% of the U.S. concrete production following the manufacturing of precast concrete and masonry units. The most significant expenditure is the cost of materials accounting for more than 50% of total concrete production costs - cement only accounts for nearly 24%. In 2009, energy costs of the U.S. concrete industry were over $610 million. Hence, energy efficiency improvements along with efficient use of materials without negatively affecting product quality and yield, especially in times of increased fuel and material costs, can significantly reduce production costs and increase competitiveness. The Energy Guide starts with an overview of the U.S. concrete industrys structure and energy use, a description of the various manufacturing processes, and identification of the major energy consuming areas in the different industry segments. This is followed by a description of general and process related energy- and cost-efficiency measures applicable to the concrete industry. Specific energy and cost savings and a typical payback period are included based on literature and case studies, when available. The Energy Guide intends to provide information on cost reduction opportunities to energy and plant managers in the U.S. concrete industry. Every cost saving opportunity should be assessed carefully prior to implementation in individual plants, as the economics and the potential energy and material savings may differ.

A Measurement Management Technology for Improving Energy Efficiency in Data Centers and Telecommunication Facilities  

SciTech Connect (OSTI)

Data center (DC) electricity use is increasing at an annual rate of over 20% and presents a concern for the Information Technology (IT) industry, governments, and the society. A large fraction of the energy use is consumed by the compressor cooling to maintain the recommended operating conditions for IT equipment. The most common way to improve the DC efficiency is achieved by optimally provisioning the cooling power to match the global heat dissipation in the DC. However, at a more granular level, the large range of heat densities of today's IT equipment makes the task of provisioning cooling power optimized to the level of individual computer room air conditioning (CRAC) units much more challenging. Distributed sensing within a DC enables the development of new strategies to improve energy efficiency, such as hot spot elimination through targeted cooling, matching power consumption at rack level with workload schedule, and minimizing power losses. The scope of Measurement and Management Technologies (MMT) is to develop a software tool and the underlying sensing technology to provide critical decision support and control for DC and telecommunication facilities (TF) operations. A key aspect of MMT technology is integration of modeling tools to understand how changes in one operational parameter affect the overall DC response. It is demonstrated that reduced ordered models for DC can generate, in less than 2 seconds computational time, a three dimensional thermal model in a 50 kft{sup 2} DC. This rapid modeling enables real time visualization of the DC conditions and enables 'what if' scenarios simulations to characterize response to 'disturbances'. One such example is thermal zone modeling that matches the cooling power to the heat generated at a local level by identifying DC zones cooled by a specific CRAC. Turning off a CRAC unit can be simulated to understand how the other CRAC utilization changes and how server temperature responds. Several new sensing technologies were added to the existing MMT platform: (1) air contamination (corrosion) sensors, (2) power monitoring, and (3) a wireless environmental sensing network. All three technologies are built on cost effective sensing solutions that increase the density of sensing points and enable high resolution mapping of DCs. The wireless sensing solution enables Air Conditioning Unit (ACU) control while the corrosion sensor enables air side economization and can quantify the risk of IT equipment failure due to air contamination. Validation data for six test sites demonstrate that leveraging MMT energy efficiency solutions combined with industry best practices results in an average of 20% reduction in cooling energy, without major infrastructure upgrades. As an illustration of the unique MMT capabilities, a data center infrastructure efficiency (DCIE) of 87% (industry best operation) was achieved. The technology is commercialized through IBM System and Technology Lab Services that offers MMT as a solution to improve DC energy efficiency. Estimation indicates that deploying MMT in existing DCs can results in an 8 billion kWh savings and projection indicates that constant adoption of MMT can results in obtainable savings of 44 billion kWh in 2035. Negotiations are under way with business partners to commercialize/license the ACU control technology and the new sensor solutions (corrosion and power sensing) to enable third party vendors and developers to leverage the energy efficiency solutions.

New Fabrication Method Improves the Efficiency and Economics of Solar Cells (Fact Sheet)  

SciTech Connect (OSTI)

Synthetic fabrication strategy optimizes the illumination geometry and transport properties of dye-sensitized solar cells. Using oriented titanium oxide (TiO{sub 2}) nanotube (NT) arrays has shown promise for dye-sensitized solar cells (DSSCs). High solar conversion efficiency requires that the incident light enters the cell from the photoelectrode side. However, for NT-based DSSCs, the light normally enters the cell through the counter electrode because a nontransparent titanium foil is typically used as the substrate for forming the aligned NTs and for making electrical contact with them. It has been synthetically challenging to prepare transparent TiO{sub 2} NT electrodes by directly anodizing Ti metal films on transparent conducting oxide (TCO) substrates because it is difficult to control the synthetic conditions. National Renewable Energy Laboratory (NREL) researchers have developed a general synthetic strategy for fabricating transparent TiO{sub 2} NT films on TCO substrates. With the aid of a conducting Nb-doped TiO{sub 2} (NTO) layer between the Ti film and TCO substrate, the Ti film can be anodized completely without degrading the TCO. The NTO layer protects the TCO from degradation through a self-terminating mechanism by arresting the electric field-assisted dissolution process at the NT-NTO interface. NREL researchers found that the illumination direction and wavelength of the light incident on the DSSCs strongly influenced the incident photon-to-current conversion efficiency, light-harvesting, and charge-collection properties, which, in turn, affect the photocurrent density, photovoltage, and solar energy conversion efficiency. Researchers also examined the effects of NT film thickness on the properties and performance of DSSCs and found that illuminating the cell from the photoelectrode side substantially increased the conversion efficiency compared with illuminating it from the counter-electrode side. This method solves a key challenge in fabricating NT-based DSSCs and determines an optimal illumination direction to use in these cells. The synthetic fabrication strategy will improve the economics and conversion efficiency of DSSCs.

Energy efficiency improvements utilising mass flow control and a ring topology in a district heating network  

Science Journals Connector (OSTI)

Abstract Heating and cooling have a major role in the energy sector, covering 46% of total final energy use worldwide. District heating (DH) is a significant technology for improving the energy efficiency of heating systems in communities, because it enables waste heat sources to be utilised economically and therefore significantly reduces the environmental impacts of power generation. As a result of new and more stringent construction regulations for buildings, the heat demands of individual buildings are decreasing and more energy-efficient heating systems have to be developed. In this study, the energy efficiency of a new DH system which includes both a new control system called mass flow control and a new network design called a ring network is examined. A topology in the Helsinki region is studied by using a commercial DH network modelling tool, Grades Heating. The district heating network is attached to a wood-burning heat station which has a heat recovery system in use. Examination is performed by means of both technical and economic analysis. The new non-linear temperature programme that is required is adopted for supply and return temperatures, which allows greater temperature cooling and smaller flow rates. Lower district heating water temperatures are essential when reducing the heat losses in the network and heat production. Mass flow control allows smaller pressure drops in the network and thus reduces the pumping power. The aim of this study was to determine the most energy-efficient DH water supply temperatures in the case network. If the ring network design is utilised, the district heating system is easier to control. As a result the total heat consumption within the heating season is reduced compared to traditional DH systems. On the basis of the results, the new DH system is significantly more energy-efficient in the case network that was examined than the traditional design. For example, average energy losses within the constraints (which consist of heat losses, pumping energy, and surplus energy from the heat recovery system) are reduced from 4.4% to 3.1%.

A survey of techniques for improving energy efficiency in embedded computing systems  

Science Journals Connector (OSTI)

Recent technological advances have greatly improved the performance and features of embedded systems. With the number of just mobile devices now reaching nearly equal to the population of Earth, embedded systems have truly become ubiquitous. These trends, however, have also made the task of managing their power consumption extremely challenging. In recent years, several techniques have been proposed to address this issue. In this paper, we survey the techniques for managing power consumption of embedded systems. We discuss the need of power management and provide a classification of the techniques on several important parameters to highlight their similarities and differences. This paper is intended to help the researchers and application-developers in gaining insights into the working of power management techniques and designing even more efficient high-performance embedded systems of tomorrow.

Energy Saving Melting and Revert Reduction Technology (E-SMARRT): Melting Efficiency Improvement  

SciTech Connect (OSTI)

Steel foundries melt recycled scrap in electric furnaces and typically consume 35-100% excess energy from the theoretical energy requirement required to pour metal castings. This excess melting energy is multiplied by yield losses during casting and finishing operations resulting in the embodied energy in a cast product typically being three to six times the theoretical energy requirement. The purpose of this research project was to study steel foundry melting operations to understand energy use and requirements for casting operations, define variations in energy consumption, determine technologies and practices that are successful in reducing melting energy and develop new melting techniques and tools to improve the energy efficiency of melting in steel foundry operations.

SciTech Connect (OSTI)

This report was prepared for the Office of Conservation, Bonneville Power Administration. The report will be used by the Office as background information to support future analysis and implementation of electricity conservation programs for owners of residential rental housing in the Northwest. The principal objective of the study was to review market research information relating to attitudes and actions of Northwest rental housing owners and, to a lesser extent, tenants toward energy conservation and energy-efficiency improvements. Available market research data on these subjects were found to be quite limited. The most useful data were two surveys of Seattle rental housing owners conducted in late 1984 for Seattle City Light. Several other surveys provided supplemental market research information in selected areas. In addition to market research information, the report also includes background information on rental housing characteristics in the Northwest.

Improving gasoline direct injection (GDI) engine efficiency and emissions with hydrogen from exhaust gas fuel reforming  

Science Journals Connector (OSTI)

Abstract Exhaust gas fuel reforming has been identified as a thermochemical energy recovery technology with potential to improve gasoline engine efficiency, and thereby reduce CO2 in addition to other gaseous and particulate matter (PM) emissions. The principle relies on achieving energy recovery from the hot exhaust stream by endothermic catalytic reforming of gasoline and a fraction of the engine exhaust gas. The hydrogen-rich reformate has higher enthalpy than the gasoline fed to the reformer and is recirculated to the intake manifold, i.e. reformed exhaust gas recirculation (REGR). The REGR system was simulated by supplying hydrogen and carbon monoxide (CO) into a conventional EGR system. The hydrogen and CO concentrations in the REGR stream were selected to be achievable in practice at typical gasoline exhaust temperatures. Emphasis was placed on comparing REGR to the baseline gasoline engine, and also to conventional EGR. The results demonstrate the potential of REGR to simultaneously increase thermal efficiency, reduce gaseous emissions and decrease PM formation.

Evaluation of soy based heavy fuel oil emulsifiers for energy efficiency and environmental improvement  

SciTech Connect (OSTI)

It is known that the emulsification of water into heavy fuel oil (No. 6) can result in improved atomization of the fuel in a combustion chamber, which results in several benefits. In this study, two soybean lecithin based emulsifiers were evaluated. The emulsifiers were added to the No. 6 fuel at 0.5% and 1 % levels and emulsions of 10% and 15% water were prepared and burned in a pilot scale combustion chamber. The results showed a significant decrease in NO{sub x} emissions, and a reduction in carbon particulates, as well as a decrease in the excess oxygen requirement when the emulsions were burned when compared to fuel oil alone and a fuel oil/water mixture without the emulsifier. It was concluded that the use of a soybean lecithin based emulsifier may be used to increase the burning efficiency of heavy fuel oils, reduce emissions and particulates, and reduce down time for cleaning. This can be very important in utility plants which burn large volumes of heavy fuel oil and are located near urban areas.

Improving Energy Efficiency of Compressed Air System Based onSystem Audit  

SciTech Connect (OSTI)

Industrial electric motor systems consume more than 600billion kWh annually, accounting for more than 50 percent of China selectricity use. The International Energy Agency estimates thatoptimizing motor systems results in an improvement of 20-25 percent,which is well-supported by experience in both the U.S. and China.Compressed air systems in China use 9.4 percent of all electricity.Compressed air use in China is growing rapidly, as new industrial plantsare built and the production processes of existing plants expand andchange. Most of these systems, whether existing or new, are not optimizedfor energy efficiency. This paper will present a practitioner'sperspective on theemergence of compressed air auditing services inChina, specifically as it pertains to Shanghai and surrounding areas.Both the methodology used and the market development of these compressedair system services will be addressed. Finally, the potential for energysaving opportunities will be described based on highlights from over 50compressed air system energy audits completed by Shanghai EnergyConservation Service Center, both during the United Nations IndustrialDevelopment Organization (UNIDO) China Motor System Energy ConservationProgram, and after this training program was completed.

Improving the Fermilab Booster Notching Efficiency, Beam Losses and Radiation Levels  

SciTech Connect (OSTI)

A fast vertical 1.08-m long kicker (notcher) located in the Fermilab Booster Long-05 straight section is currently used to remove 3 out of 84 circulating bunches after injection to generate an abort gap. With the maximum magnetic field of 72.5 Gauss, it removes only 87% of the 3-bunch intensity at 400 MeV, with 75% loss on pole tips of the focusing Booster magnets, 11% on the Long-06 collimators, and 1% in the rest of the ring. We propose to improve the notching efficiency and reduce beam loss in the Booster by using three horizontal kickers in the Long-12 section. STRUCT calculations show that using horizontal notchers, one can remove up to 96% of the 3-bunch intensity at 400-700 MeV, directing 95% of it to a new beam dump at the Long-13 section. This fully decouples notching and collimation. The beam dump absorbs most of the impinging proton energy in its jaws. The latter are encapsulated into an appropriate radiation shielding that reduces impact on the machine components, personnel and environment to the tolerable levels. MARS simulations show that corresponding prompt and residual radiation levels can be reduced ten times compared to the current ones.

Advanced Electric Systems and Aerodynamics for Efficiency Improvements in Heavy Duty Trucks  

SciTech Connect (OSTI)

The Advanced Electric Systems and Aerodynamics for Efficiency Improvements in Heavy Duty Trucks program (DE-FC26-04NT42189), commonly referred to as the AES program, focused on areas that will primarily benefit fuel economy and improve heat rejection while driving over the road. The AES program objectives were to: (1) Analyze, design, build, and test a cooling system that provided a minimum of 10 percent greater heat rejection in the same frontal area with no increase in parasitic fan load. (2) Realize fuel savings with advanced power management and acceleration assist by utilizing an integrated starter/generator (ISG) and energy storage devices. (3) Quantify the effect of aerodynamic drag due to the frontal shape mandated by the area required for the cooling system. The program effort consisted of modeling and designing components for optimum fuel efficiency, completing fabrication of necessary components, integrating these components into the chassis test bed, completing controls programming, and performance testing the system both on a chassis dynamometer and on the road. Emission control measures for heavy-duty engines have resulted in increased engine heat loads, thus introducing added parasitic engine cooling loads. Truck electrification, in the form of thermal management, offers technological solutions to mitigate or even neutralize the effects of this trend. Thermal control offers opportunities to avoid increases in cooling system frontal area and forestall reduced fuel economy brought about by additional aerodynamic vehicle drag. This project explored such thermal concepts by installing a 2007 engine that is compliant with current regulations and bears additional heat rejection associated with meeting these regulations. This newer engine replaced the 2002 engine from a previous project that generated less heat rejection. Advanced power management, utilizing a continuously optimized and controlled power flow between electric components, can offer additional fuel economy benefits to the heavy-duty trucking industry. Control software for power management brings added value to the power distribution and energy storage architecture on board a truck with electric accessories and an ISG. The research team has built upon a previous truck electrification project, formally, 'Parasitic Energy Loss Reduction and Enabling Technologies for Class 7/8 Trucks', DE-FC04-2000AL6701, where the fundamental concept of electrically-driven accessories replacing belt/gear-driven accessories was demonstrated on a Kenworth T2000 truck chassis. The electrical accessories, shown in Figure 1, were controlled to provide 'flow on demand' variable-speed operation and reduced parasitic engine loads for increased fuel economy. These accessories also provided solutions for main engine idle reduction in long haul trucks. The components and systems of the current project have been integrated into the same Kenworth T2000 truck platform. Reducing parasitic engine loading by decoupling accessory loads from the engine and driving them electrically has been a central concept of this project. Belt or gear-driven engine accessories, such as water pump, air conditioning compressor, or air compressor, are necessarily tied to the engine speed dictated by the current vehicle operating conditions. These conventional accessory pumps are sized to provide adequate flow or pressure at low idle or peak torque speeds, resulting in excess flow or pressure at cruising or rated speeds. The excess flow is diverted through a pressure-minimizing device such as a relief valve thereby expending energy to drive unnecessary and inefficient pump operation. This inefficiency causes an increased parasitic load to the engine, which leads to a loss of usable output power and decreased fuel economy. Controlling variable-speed electric motors to provide only the required flow or pressure of a particular accessory system can yield significant increases in fuel economy for a commercial vehicle. Motor loads at relatively high power levels (1-5 kW, or higher) can be efficiently provided

Magnetism reflectometer study shows LiF layers improve efficiency in spin valve devices  

SciTech Connect (OSTI)

New, more efficient materials for spin valves - a device used in magnetic sensors, random access memories, and hard disk drives - may be on the way based on research using the magnetism reflectometer at Oak Ridge National Laboratory (ORNL). Spin valve devices work by means of two or more conducting magnetic material layers that alternate their electrical resistance depending on the layers alignment. Giant magnetoresistance is a quantum mechanical effect first observed in thin film structures about 20 years ago. The effect is observed as a significant change in electrical resistance, depending on whether the magnetization of adjacent ferromagnetic layers is in a parallel or an antiparallel magnetic alignment. 'What we are doing here is developing new materials. The search for new materials suitable for injecting and transferring carriers with a preferential spin orientation is most important for the development of spintronics,' said Valeria Lauter, lead instrument scientist on the magnetism reflectometer at the Spallation Neutron Source (SNS), who collaborated on the experiment. The researchers discovered that the conductivity of such materials is improved when an organic polymer semiconductor layer is placed between the magnetic materials. Organic semiconductors are now the material of choice for future spin valve devices because they preserve spin coherence over longer times and distances than conventional semiconductors. While research into spin valves has been ongoing, research into organic semiconductors is recent. Previous research has shown that a 'conductivity mismatch' exists in spin valve systems in which ferromagnetic metal electrodes interface with such organic semiconductors as Alq3 ({pi}-conjugated molecule tris(8-hydroxy-quinoline) aluminium). This mismatch limits the efficient injection of the electrons from the electrodes at the interface with the semiconductor material. However, lithium fluoride (LiF), commonly used in light-emitting diodes, has been found to enhance the injection of electrons through the semiconductor. Researchers from the University of Alabama and ORNL used polarized neutrons at the magnetism reflectometer at SNS to investigate the electronic, magnetic, and structural properties of the electrodes in a novel system. In this system, the magnetic layers cobalt and Ni{sub 80}Fe{sub 20} are interfaced with spacer layers composed of the organic semiconductor Alq3. A coupling layer of LiF is inserted to separate the magnetized layers from the semiconductor. 'ALQ3 is an organic semiconductor material,' said Lauter. 'Normally in these systems a first magnetic layer is grown on a hard substrate so that one can get the controlled magnetic parameters. Then you grow the organic semiconductor layer, followed by another magnetic material layer, such as cobalt.' In addition to determining the effect of the LiF layers on the efficiency of the electron injection, the researchers wanted to determine the magnetic properties of the cobalt and Ni{sub 80}Fe{sub 20} as well as the interfacial properties: whether there is interdiffusion of cobalt through the LiF layer to the semiconductor, for example. The researchers used polarized neutrons at beam line 4A to probe the entire, layer-by-layer assembly of the system. 'Reflectometry with polarized neutrons is a perfect method to study thin magnetic films,' Lauter said. 'These thin films - if you put one on a substrate, you see it just like a mirror. However, this mirror has a very complicated internal multilayer structure. The neutrons look inside this complicated structure and characterize each and every interface. Due to the depth sensitivity of the method, we measure the structural and magnetic properties of each layer with the resolution of 0.5 nm. The neutron scattering results found that inserting LiF as a barrier significantly improves the quality of the interface, increasing the injection of electrons from the magnetic layer through the organic semiconductor in the spin valve and enhancing the overall properties of the system. In related work the magneti

Two-step fuel oxidation to improve efficiency in the conversion of chemical energy into work  

SciTech Connect (OSTI)

It is well known that in the conversion of chemical exergy into work a remarkable percentage of exergy is destroyed during the combustion process. Obviously, hypothetical reversible combustions, as proposed in some papers, are not to be taken into account. On the contrary, recent studies of a new system to increase the efficiency of the conversion of chemical exergy into work appear interesting. The proposed system includes a gas turbine system with chemical-looping combustion where a metal oxide is used as an oxygen carrier. Instead of conventional combustion, the oxidation of fuel is carried out in a two-step reaction. The first step is an endothermic reaction in which a metal oxide is reduced by fuel at low temperature and the second step an exothermic reaction in which the products of the former reaction are subjected to oxidation. The thermal energy of low exergy value in the exhaust gas is employed to drive the endothermic reaction. Various systems have been proposed and tested. The power-generation system (called CLSA), with chemical-looping combustion and air saturation seems the most convenient. When only saturated air is used, exergy destruction becomes small in the middle- and low temperature range. However, the inefficiency in the high temperature range remains. On the other hand, when only chemical-looping combustion is used, exergy destruction becomes small in the high- and middle temperature range. However, the inefficiency in the low-temperature range is now not removed. When both technologies are combined, exergy efficiency may become much greater than that obtained from each individual process. The synergistic effect of combining these two technologies is analogous to the improvement achieved when a combined system was designed as a new power-generation system by combining a gas turbine with a steam turbine. For a model system, an exergy efficiency of 53.3% is obtained when the process water is recovered and a value of about 55% is obtained when water is not recovered. A significant advantage of the CLSA system is that CO{sub 2} can be easily recovered. The CO{sub 2} produced in the reduction reactor is not diluted by air since air and fuel enter different reactors. This is quite different from a traditional combustor in which CO{sub 2} is diluted in air and hence cannot be concentrated and separated economically. In the CLSA system, since the exhaust gas from the reduction reactor is composed only of high-concentration CO{sub 2} and water vapor, CO{sub 2} can be easily recovered by cooling the exhaust gas and removing the liquid water, i.e. very little energy expenditure is required for recovering CO{sub 2} from the exhaust gas. The recovered CO{sub 2} may be utilized, e.g., in artificial photosynthesis, whereas a simple recovery without any utilization but only to reduce greenhouse effect seems questionable. Another significant characteristic of CLSA system is that the most of the water vapor in the exhaust gas can be recovered by cooling the exhaust gas from the oxidation reactor. In chemical-looping combustion, fuel is not burned directly and the gas discharged from the oxidation reactor has no impurities from the fuel. Hence, there will be no corrosion of the apparatus when the exhaust gas is cooled to a very low temperature and low cost materials can be utilized for the heat exchangers. Because of the recycling of the most part of water, the CLSA system can be used in locations with limited water resources. Chemical-looping combustion system can be also combined with an integrated coal gasification and this topic appears very interesting. Indeed, to achieve better conversion efficiencies and lower pollutant emissions in power plants, new technologies that combines coal gasification with a gas turbine based combined cycle have been extensively studied worldwide.

Analysis of the impacts of building energy efficiency policies and technical improvements on China's future energy demand  

Science Journals Connector (OSTI)

In this paper, the LEAP (Long-range Energy Alternatives Planning system) 2000 model and scenario analysis were utilised to study the impact of implementing building energy efficiency policies and promoting related technical improvements on China's future building energy demand up to 2020. In the coming 20 years, China's building energy consumption is expected to increase and will be the main contributor to the growth in China's future energy demand. Without the rational induction of energy efficiency and environmental policies, China's building energy consumption may reach 860 Mtce in 2020 from 197 Mtce in 2000. On the other hand, China possesses huge energy saving potential in the building area. With the enforcement and adoption of related building energy efficiency policies and technical improvement measures, energy consumption in the building sector might decrease to 480 Mtce by 2020; and the energy saving potential might reach 380 Mtce.

The FEMP Awards Program: Fostering Institutional Change and Energy Management Excellence  

SciTech Connect (OSTI)

This report assesses the use of institutional change principles and the institutional impact of award-winning projects through interviews with 22 Department of Energy Federal Energy Management Program (DOE FEMP) award winners. Award winners identified institutional facilitators and barriers in their projects and programs as well as factors in their implementation processes, thus providing information that can guide other efforts. We found that award winners do use strategies based on eight principles of institutional change, most frequently in terms of making changes to infrastructure, engaging leadership, and capitalizing on multiple motivations for making an energy efficiency improvement. The principles drawn on the least often were commitment and social empowerment. Award winners also faced five major types of obstacles that were institutional in nature: lack of resources, constraints of rules, psychological barriers, lack of information, and communication problems. We also used the seven categories of Energy Management Excellence (EME) as a lens to interpret the interview data and assess whether these categories relate to established institutional change principles. We found that the eight principles reflect strategies that have been found to be useful in improving energy efficiency in organizations, whereas the EME categories capture more of a blend of social contextual factors and strategies. The EME categories fill in some of the social context gaps that facilitate institutional change and energy management excellence, for example, personal persistence, a culture that supports creativity and innovation, regular engagement with tenants, contractors, and staff at all levels. Taking together the use of principles, EME criteria, and obstacles faced by interviewees, we make recommendations for how FEMP can better foster institutional change in federal agencies.

Theoretical Limits of Photovoltaics Efficiency and Possible Improvements by Intuitive Approaches Learned from Photosynthesis and Quantum Coherence  

E-Print Network [OSTI]

In this review, we present and discussed the main trends in photovoltaics with emphasize on the conversion efficiency limits. The theoretical limits of various photovoltaics device concepts are presented and analyzed using a flexible detailed balance model where more discussion emphasize is toward the losses. Also, few lessons from nature and other fields to improve the conversion efficiency in photovoltaics are presented and discussed as well. From photosynthesis, the perfect exciton transport in photosynthetic complexes can be utilized for PVs. Also, we present some lessons learned from other fields like recombination suppression by quantum coherence. For example, the coupling in photosynthetic reaction centers is used to suppress recombination in photocells.

Improved performance of the Boeing/LANL FEL experiment: Extraction efficiency and cavity-length detuning effects  

Science Journals Connector (OSTI)

We observed significant improvement in the performance of the Boeing/LANL free-electron laser (FEL) experiment in the last year. Some of the more graphic demonstrations of this improved performance are presented in the time-resolved optical spectral measurements (streak/spectrometer) and the electron-beam spectral measurements. We have observed an extraction efficiency of about 14% for the uniform wiggler and nearly 1% for the tapered-wiggler experiment. We also present experimental evidence consistent with a sideband instability and its suppression by cavity-length detuning.

Improvement of energy-conversion efficiency from laser to proton beam in a laser-foil interaction  

Science Journals Connector (OSTI)

Improvement of energy-conversion efficiency from laser to proton beam is demonstrated by particle simulations in a laser-foil interaction. When an intense short-pulse laser illuminates the thin-foil target, the foil electrons are accelerated around the target by the ponderomotive force. The hot electrons generate a strong electric field, which accelerates the foil protons, and the proton beam is generated. In this paper a multihole thin-foil target is proposed in order to increase the energy-conversion efficiency from laser to protons. The multiholes transpiercing the foil target help to enhance the laser-proton energy-conversion efficiency significantly. Particle-in-cell 2.5-dimensional (x, y, vx, vy, vz) simulations present that the total laser-proton energy-conversion efficiency becomes 9.3% for the multihole target, though the energy-conversion efficiency is 1.5% for a plain thin-foil target. The maximum proton energy is 10.0MeV for the multihole target and is 3.14MeV for the plain target. The transpiercing multihole target serves as a new method to increase the energy-conversion efficiency from laser to ions.

New configurations of a heat recovery absorption heat pump integrated with a natural gas boiler for boiler efficiency improvement  

SciTech Connect (OSTI)

Conventional natural gas-fired boilers exhaust flue gas direct to the atmosphere at 150 200 C, which, at such temperatures, contains large amount of energy and results in relatively low thermal efficiency ranging from 70% to 80%. Although condensing boilers for recovering the heat in the flue gas have been developed over the past 40 years, their present market share is still less than 25%. The major reason for this relatively slow acceptance is the limited improvement in the thermal efficiency of condensing boilers. In the condensing boiler, the temperature of the hot water return at the range of 50 60 C, which is used to cool the flue gas, is very close to the dew point of the water vapor in the flue gas. Therefore, the latent heat, the majority of the waste heat in the flue gas, which is contained in the water vapor, cannot be recovered. This paper presents a new approach to improve boiler thermal efficiency by integrating absorption heat pumps with natural gas boilers for waste heat recovery (HRAHP). Three configurations of HRAHPs are introduced and discussed. The three configurations are modeled in detail to illustrate the significant thermal efficiency improvement they attain. Further, for conceptual proof and validation, an existing hot water-driven absorption chiller is operated as a heat pump at operating conditions similar to one of the devised configurations. An overall system performance and economic analysis are provided for decision-making and as evidence of the potential benefits. These three configurations of HRAHP provide a pathway to achieving realistic high-efficiency natural gas boilers for applications with process fluid return temperatures higher than or close to the dew point of the water vapor in the flue gas.

Energy Efficiency Improvement and Cost Saving Opportunities for Cement Making. An ENERGY STAR Guide for Energy and Plant Managers  

SciTech Connect (OSTI)

The cost of energy as part of the total production costs in the cement industry is significant, warranting attention for energy efficiency to improve the bottom line. Historically, energy intensity has declined, although more recently energy intensity seems to have stabilized with the gains. Coal and coke are currently the primary fuels for the sector, supplanting the dominance of natural gas in the 1970s. Most recently, there is a slight increase in the use of waste fuels, including tires. Between 1970 and 1999, primary physical energy intensity for cement production dropped 1 percent/year from 7.3 MBtu/short ton to 5.3 MBtu/short ton. Carbon dioxide intensity due to fuel consumption and raw material calcination dropped 16 percent, from 609 lb. C/ton of cement (0.31 tC/tonne) to 510 lb. C/ton cement (0.26 tC/tonne). Despite the historic progress, there is ample room for energy efficiency improvement. The relatively high share of wet-process plants (25 percent of clinker production in 1999 in the U.S.) suggests the existence of a considerable potential, when compared to other industrialized countries. We examined over 40 energy efficient technologies and measures and estimated energy savings, carbon dioxide savings, investment costs, and operation and maintenance costs for each of the measures. The report describes the measures and experiences of cement plants around the wold with these practices and technologies. Substantial potential for energy efficiency improvement exists in the cement industry and in individual plants. A portion of this potential will be achieved as part of (natural) modernization and expansion of existing facilities, as well as construction of new plants in particular regions. Still, a relatively large potential for improved energy management practices exists.

This paper briefly describes population and energy use trends and their consequences, particularly to the Caribbean region. Historical trends for transitional countries show a decrease in population growth rate as annual per capita commercial energy use increases. If trends continue, an increase in per capita energy will be important to stabilizing populations of transitional countries. Energy efficiency improvements, the role of fossil energy, and the use of alternative energy sources in Caribbean nations are briefly discussed. 6 refs., 3 figs.

Improved Energy Conversion Efficiency in Wide-Bandgap Cu(In,Ga)Se2 Solar Cells: Preprint  

SciTech Connect (OSTI)

This report outlines improvements to the energy conversion efficiency in wide bandgap (Eg>1.2 eV) solar cells based on CuIn1-xGaxSe2. Using (a) alkaline containing high temperature glass substrates, (b) elevated substrate temperatures 600?C-650?C and (c) high vacuum evaporation from elemental sources following NREL's three-stage process, we have been able to improve the performance of wider bandgap solar cells with 1.2efficiencies >18% for absorber bandgaps ~1.30 eV and efficiencies ~16% for bandgaps up to ~1.45 eV. In comparing J-V parameters in similar materials, we establish gains in the open-circuit voltage and, to a lesser degree, the fill factor value, as the reason for the improved performance. The higher voltages seen in these wide gap materials grown at high substrate temperatures may be due to reduced recombination at the grain boundary of such absorber films. Solar cell results, absorber materials characterization, and experimental details are reported.

Improved high-efficiency silicon concentrator cells for medium concentration applications  

SciTech Connect (OSTI)

This report describes efforts toward design simplification of Si concentrator cells capable of efficiencies in the 25-30% range. A discussion is given on the principal issues involved in the design and fabrication of both backside-contact cells and cells with frontside grids. Several proposed designs are detailed. Results include 23% two-sided 1.5625 cm/sup 2/ cells operating at 14 W/cm/sup 2/ of incident power. This simple design requires only one mask alignment and should approach 25% with further development. With an additional alignment, cells that are 27% efficient are feasible. Neither of these designs will require prismatic cover glasses to achieve this performance. In addition, a new backside contact cell design is described that requires only one mask and no alignments. Cells of this type were demonstrated to be 15.4% efficient at 4 W/cm/sup 2/, without AR coatings or texturization. Fundamental studies of the limiting parameters indicate that the design will exceed 25% in efficiency when fully developed. Finally, a new light-trapping scheme is proposed which could have the effect of increasing the attainable efficiencies of silicon concentrator cells to 32-33%. This same scheme might also be utilized in ways which would allow very simple low-cost cell designs to achieve results comparable to the best cells demonstrated to date. Assorted other practically-oriented results on metalization development, cell mounting, and qualification tests are also presented. 26 refs., 31 figs.

Evaluation of design options for improving the energy efficiency of an environmentally safe domestic refrigerator-freezer  

SciTech Connect (OSTI)

In order to reduce greenhouse emissions from power plants and respond to regulatory actions arising from the National Appliance Energy Conservation Act (NAECA), several design options were investigated for improving the energy efficiency of a conventionally designed, domestic refrigerator-freezer. The options, such as improved cabinet insulation and high-efficiency compressor and fans, were incorporated into a prototype refrigerator-freezer cabinet and refrigeration system to produce a unit that is superior from an environmental viewpoint due to its lower energy consumption and the use of refrigerant HFC-134a as a replacement for CFC-12. Baseline energy performance of the original 1993 production refrigerator-freezer, along with cabinet heat load and compressor calorimeter test results, were extensively documented to provide a firm basis for experimentally measured energy savings. A detailed refrigerator system computer model was used to evaluate the energy savings for several design modifications that, collectively, could achieve a targeted energy consumption of 1.00 kWh/d for a 20 ft{sup 3} (570 l) top-mount, automatic-defrost, refrigerator-freezer. The energy consumption goal represents a 50% reduction in the 1993 NAECA standard for units of this size. Following the modeling simulation, laboratory prototypes were fabricated and tested to experimentally verify the analytical results and aid in improving the model in those areas where discrepancies occurred. While the 1.00 kWh/d goal was not achieved with the modifications, a substantial energy efficiency improvement of 22% (1.41 kWh/d) was demonstrated using near-term technologies. It is noted that each improvement exacts a penalty in terms of increased cost or system complexity/reliability. Further work on this project will analyze cost-effectiveness of the design changes and investigate alternative, more-elaborate, refrigeration system changes to further reduce energy consumption.

Improving the efficiency and availability analysis of a modified reheat regenerative Rankine cycle  

SciTech Connect (OSTI)

Reheating in a reheat regenerative steam power cycle increases efficiency by increasing the average temperature of heat reception, but also increases the irreversibility of feed water heaters by raising the temperature of the superheated steam used for the regenerative process. This paper introduces some modifications to the regular reheat regenerative steam power cycle that reduce the irreversibility of the regenerative process. An availability analysis of the modified cycle and the regular reheat regenerative cycle as well as a comparison study between both cycles is done. The results indicate that a gain in energy efficiency of up to 2.5% as the steam generator pressure varies is obtained when applying such modifications at the same conditions of pressure, temperature's number of reheating stages, and feed water heaters. The availability analysis showed that such increase in efficiency is due to the reduction of the irreversibility of the regeneration process of the modified cycle.

Is it viable to improve light output efficiency by nano-light-emitting diodes?  

SciTech Connect (OSTI)

Nanopillar arrays with InGaN/GaN multiple-quantum-disks (MQDs) are fabricated by focused-ion-beam milling with surface damage layer removed by KOH wet etching. Nano-light-emitting diodes (Nano-LEDs) made of the InGaN/GaN MQD nanopillars are found to have 19.49% less output power than that of a conventional LED. The reasons are analyzed in detail and considering their current-voltage and electroluminescence characteristics, internal quantum efficiency, external quantum efficiency, light extraction, and wall-plug efficiency. Our results suggest that nanopillar-LED can outperform if the density can be increased to 2.81??10{sup 9}?cm{sup ?2} with the size unchanged or the size can be increased to 854.4?nm with the density unchanged.

R and D for improved efficiency, small steam turbines: Phase I. Final technical report  

SciTech Connect (OSTI)

Results of an investigation of the development of a class of highly efficient steam turbines in the 500 to 5000 horsepower range are presented; these new machines are expected to have efficiences between 70 and 85%. The turbines are based on the concept of one or more high-speed radial inflow turbine modules driving a low-speed bull gear. Each module operates then at optimal specific speed, which yields high efficiency compared to the partial admission Curtiss stages currently used. The project has two phases. Phase 1 includes investigation and interpretation of the market for small steam turbines and definition of the radial inflow turbine (RIT) configurations best suited to penetrate a significant portion of this market. Phase 1 concludes with a recommended configuration. (MCW)

Efficiency improvement and torque ripple minimization of Switched Reluctance Motor using FEM and Seeker Optimization Algorithm

Abstract In this paper, performance optimization of Switched Reluctance Motor (SRM) was determined using Seeker Optimization Algorithm (SOA). The most efficient aim of the algorithm was found for maximum torque value at a minimum mass of the entire construction, following changing the geometric parameters. The optimization process was carried out using a combination of Seeker Optimization Algorithm and Finite Element Method (FEM). Fitness value was calculated by FEM analysis using COMSOL3.4, and the SOA was realized by MATLAB. The proposed method has been applied for a case study and it has been also compared with Genetic Algorithm (GA). The results show that the optimized motor using SOA had higher torque value and efficiency with lower mass and torque ripple, exhibiting the validity of this methodology for SRM design.

Energy efficiency improvements for refrigerator/freezers using prototype doors containing gas-filled panel insulating systems  

SciTech Connect (OSTI)

Energy efficiency improvements in domestic refrigerator/freezers, are directly influenced by the overall thermal performance of the cabinet and doors. An advanced system for reducing heat gain is Gas-Filled Panel thermal insulation technology. Gas-Filled Panels contain a low-conductivity, inert gas at atmospheric pressure and employ a reflective baffle to suppress radiation and convection within the gas. This paper presents energy use test results for a 1993 model 500 liter top mount refrigerator/freezer operated with its original doors and with a series of alternative prototype doors. Gas-Filled Panel technology was used in two types of prototype refrigerator/freezer doors. In one design, panels were used in composite with foam in standard metal door pans; this design yielded no measurable energy savings. In the other design, special polymer door pans were fitted with panels that fill nearly all of the available insulation volume; this design yielded a 6.5% increase in energy efficiency for the entire refrigerator/freezer. The EPA Refrigerator Analysis computer program has been used to predict the change in daily energy consumption with the alternative doors. The computer model also projects a 25% energy efficiency improvement for a refrigerator/freezer that would use Gas-Filled Panel insulation throughout the cabinet as well as the doors.

Development of a Supercritical Carbon Dioxide Brayton Cycle: Improving VHTR Efficiency and Testing Material Compatibility - Final Report  

SciTech Connect (OSTI)

Generation IV reactors will need to be intrinsically safe, having a proliferation-resistant fuel cycle and several advantages relative to existing light water reactor (LWR). They, however, must still overcome certain technical issues and the cost barrier before it can be built in the U.S. The establishment of a nuclear power cost goal of 3.3 cents/kWh is desirable in order to compete with fossil combined-cycle, gas turbine power generation. This goal requires approximately a 30 percent reduction in power cost for stateof-the-art nuclear plants. It has been demonstrated that this large cost differential can be overcome only by technology improvements that lead to a combination of better efficiency and more compatible reactor materials. The objectives of this research are (1) to develop a supercritical carbon dioxide Brayton cycle in the secondary power conversion side that can be applied to the Very-High-Temperature Gas-Cooled Reactor (VHTR), (2) to improve the plant net efficiency by using the carbon dioxide Brayton cycle, and (3) to test material compatibility at high temperatures and pressures. The reduced volumetric flow rate of carbon dioxide due to higher density compared to helium will reduce compression work, which eventually increase plant net efficiency.

Improved charge breeding efficiency of light ions with an electron cyclotron resonance ion source  

SciTech Connect (OSTI)

The Californium Rare Isotope Breeder Upgrade is a new radioactive beam facility for the Argonne Tandem Linac Accelerator System (ATLAS). The facility utilizes a {sup 252}Cf fission source coupled with an electron cyclotron resonance ion source to provide radioactive beam species for the ATLAS experimental program. The californium fission fragment distribution provides nuclei in the mid-mass range which are difficult to extract from production targets using the isotope separation on line technique and are not well populated by low-energy fission of uranium. To date the charge breeding program has focused on optimizing these mid-mass beams, achieving high charge breeding efficiencies of both gaseous and solid species including 14.7% for the radioactive species {sup 143}Ba{sup 27+}. In an effort to better understand the charge breeding mechanism, we have recently focused on the low-mass species sodium and potassium which up to present have been difficult to charge breed efficiently. Unprecedented charge breeding efficiencies of 10.1% for {sup 23}Na{sup 7+} and 17.9% for {sup 39}K{sup 10+} were obtained injecting stable Na{sup +} and K{sup +} beams from a surface ionization source.

Development of Foster Wheeler's Vision 21 Partial Gasification Module  

SciTech Connect (OSTI)

The US Department of Energy (DOE) has awarded Foster Wheeler Development Corporation a contract to develop a partial gasification module (PGM) that represents a critical element of several potential coal-fired Vision 21 plants. When utilized for electrical power generation, these plants will operate with efficiencies greater than 60% while producing near zero emissions of traditional stack gas pollutants. The new process partially gasifies coal at elevated pressure producing a coal derived syngas and a char residue. The syngas can be used to fuel the most advanced power producing equipment such as solid oxide fuel cells or gas turbines or processed to produce clean liquid fuels or chemicals for industrial users. The char residue is not wasted; it can also be used to generate electricity by fueling boilers that drive the most advanced ultra-supercritical pressure steam turbines. The unique aspect of the process is that it utilizes a pressurized circulating fluidized bed partial gasifier and does not attempt to consume the coal in a single step. To convert all the coal to syngas in a single step requires extremely high temperatures ({approx} 2500 to 2800F) that melt and vaporize the coal and essentially drive all coal ash contaminants into the syngas. Since these contaminants can be corrosive to power generating equipment, the syngas must be cooled to near room temperature to enable a series of chemical processes to clean the syngas. Foster Wheeler's process operates at much lower temperatures that control/minimize the release of contaminants; this eliminates/minimizes the need for the expensive, complicated syngas heat exchangers and chemical cleanup systems typical of high temperature gasification. By performing the gasification in a circulating bed, a significant amount of syngas can still be produced despite the reduced temperature and the circulating bed allows easy scale up to large size plants. Rather than air, it can also operate with oxygen to facilitate sequestration of stack gas carbon dioxide gases for a 100% reduction in greenhouse gas emissions. The amount of syngas and char produced by the PGM can be tailored to fit the production objectives of the overall plant, i.e., power generation, clean liquid fuel production, chemicals production, etc. Hence, PGM is a robust building block that offers all the advantages of coal gasification but in a more user friendly form; it is also fuel flexible in that it can use alternative fuels such as biomass, sewerage sludge, etc. This paper describes the test program and pilot plant that will be used to develop the PGM.

Cognitive Automation Strategies Improving Use-efficiency of Carrier and Content of Information  

Science Journals Connector (OSTI)

Abstract The production paradigm of mass customization puts high demand on the production system and the people who works there. This is especially true for final assembly where the number of variants is the richest. To handle this variety, the operator needs the correct information accessible at the right time; the operator wants to know how and when to assemble what part. What is correct information includes the amount of information (content of information), how it is presented (carrier of information) and who is the receiver (specific operator). The strategy for Cognitive Automation will be more and more important for companies within this paradigm. This paper aims to show the use-efficiency of information, both carrier and content, in two industrial case studies. Furthermore how the cognitive automation strategy within a company is connected to the maturity of technology.

Ways to improve the efficiency and reliability of radio frequency driven negative ion sources for fusion  

SciTech Connect (OSTI)

Large RF driven negative hydrogen ion sources are being developed at IPP Garching for the future neutral beam injection system of ITER. The overall power efficiency of these sources is low, because for the RF power supply self-excited generators are utilized and the plasma is generated in small cylindrical sources (drivers) and expands into the source main volume. At IPP experiments to reduce the primary power and the RF power required for the plasma production are performed in two ways: The oscillator generator of the prototype source has been replaced by a transistorized RF transmitter and two alternative driver concepts, a spiral coil, in which the field is concentrated by ferrites, which omits the losses by plasma expansion and a helicon source are being tested.

The Role of Emerging Technologies in Improving Energy Efficiency:Examples from the Food Processing Industry  

SciTech Connect (OSTI)

For over 25 years, the U.S. DOE's Industrial Technologies Program (ITP) has championed the application of emerging technologies in industrial plants and monitored these technologies impacts on industrial energy consumption. The cumulative energy savings of more than 160 completed and tracked projects is estimated at approximately 3.99 quadrillion Btu (quad), representing a production cost savings of $20.4 billion. Properly documenting the impacts of such technologies is essential for assessing their effectiveness and for delivering insights about the optimal direction of future technology research. This paper analyzes the impacts that several emerging technologies have had in the food processing industry. The analysis documents energy savings, carbon emissions reductions and production improvements and assesses the market penetration and sector-wide savings potential. Case study data is presented demonstrating the successful implementation of these technologies. The paper's conclusion discusses the effects of these technologies and offers some projections of sector-wide impacts.

Efficiency Improvement Opportunities for Light-Duty Natural-Gas-Fueled Vehicles  

SciTech Connect (OSTI)

The purpose of this report is to evaluate and make recommendations concerning technologies that promise to improve the efilciency of compressed natural gas (CNG) light-duty vehicles. Technical targets for CNG automotive technology given in the March 1998 OffIce of Advanced Automotive Technologies research and development plan were used as guidance for this effort. The technical target that necessitates this current study is to validate technologies that enable CNG light vehicles to have at least 10% greater - fuel economy (on a miles per gallon equivalent basis) than equivalent gasoline vehicles by 2006. Other tar- gets important to natural gas (NG) automotive technology and this study are to: (1) increase CNG vehicle range to 380 miles, (2) reduce the incremental vehicle cost (CNG vs gasoline) to $1500, and (3) meet the California ultra low-emission vehicle (ULEV) and Federal Tier 2 emission standards expected to be in effect in 2004.

Steam systems in industry: Energy use and energy efficiency improvement potentials  

SciTech Connect (OSTI)

Steam systems are a part of almost every major industrial process today. Thirty-seven percent of the fossil fuel burned in US industry is burned to produce steam. In this paper we will establish baseline energy consumption for steam systems. Based on a detailed analysis of boiler energy use we estimate current energy use in boilers in U.S. industry at 6.1 Quads (6.4 EJ), emitting almost 66 MtC in CO{sub 2} emissions. We will discuss fuels used and boiler size distribution. We also describe potential savings measures, and estimate the economic energy savings potential in U.S. industry (i.e. having payback period of 3 years or less). We estimate the nationwide economic potential, based on the evaluation of 16 individual measures in steam generation and distribution. The analysis excludes the efficient use of steam and increased heat recovery. Based on the analysis we estimate the economic potential at 18-20% of total boiler energy use, resulting in energy savings approximately 1120-1190 TBtu ( 1180-1260 PJ). This results in a reduction of CO{sub 2} emissions equivalent to 12-13 MtC.

Improved power efficiency for very-high-temperature solar-thermal-cavity receivers  

DOE Patents [OSTI]

This invention is an improved solar energy cavity receiver for exposing materials and components to high temperatures. The receiver includes a housing having an internal reflective surface defining a cavity and having an inlet for admitting solar radiation thereto. A photothermal absorber is positiond in the cavity to receive radiation from the inlet. A reflective baffle is positioned between the absorber and the inlet to severely restrict the re-radiation of energy through the inlet. The front surface of the baffle defines a narrow annulus with the internal reflective surface of the housing. The front surface of the baffle is contoured to reflect incoming radiation onto the internal surface of the housing, from which it is reflected through the annulus and onto the front surface of the absorber. The back surface of the baffle intercepts radiation from the front of the absorber. With this arrangement, a high percentage of the solar power input is retained in the cavity; thus, high internal temperatues are attained.

Erosion-Resistant Nanocoatings for Improved Energy Efficiency in Gas Turbines  

SciTech Connect (OSTI)

The objective of this Stage Gate IV project was to test and substantiate the viability of an erosion?resistant nanocoating for application on compressor airfoils for gas turbines in both industrial power generation and commercial aviation applications. To effectively complete this project, the National Energy Technology Laboratorys Office of Research & Development teamed with MDS Coating Technologies Inc. (MCT), Delta Air Lines ? Technical Operations Division (Delta Tech Ops), and Calpine Corporation. The coating targeted for this application was MCTs Next Generation Coating, version 4 (NGC?v4 ? with the new registered trademark name of BlackGold). The coating is an erosion and corrosion resistant composite nanostructured coating. This coating is comprised of a proprietary ceramic?metallic nano?composite construction which provides enhanced erosion resistance and also retains the aerodynamic geometry of the airfoils. The objective of the commercial aviation portion of the project was to substantiate the coating properties to allow certification from the FAA to apply an erosion?resistant coating in a commercial aviation engine. The goal of the series of tests was to demonstrate that the durability of the airfoils is not affected negatively with the application of the NGC v4 coating. Tests included erosion, corrosion, vibration and fatigue. The results of the testing demonstrated that the application of the coating did not negatively impact the properties of the blades, especially fatigue performance which is of importance in acceptance for commercial aviation applications. The objective of the industrial gas turbine element of the project was to evaluate the coating as an enabling technology for inlet fogging during the operation of industrial gas turbines. Fluid erosion laboratory scale tests were conducted to simulate inlet fogging conditions. Results of these tests indicated that the application of the erosion resistant NGC?v4 nanocoating improved the resistance to simulated inlet fogging conditions by a factor of 10 times. These results gave confidence for a field trial at Calpines power plant in Corpus Christi, TX, which commenced in April 2012. This test is still on?going as of November 2013, and the nanocoated blades have accumulated over 13,000 operational hours on this specific power plant in approximately 19 months of operation.

INVESTIGATION OF EFFICIENCY IMPROVEMENTS DURING CO2 INJECTION IN HYDRAULICALLY AND NATURALLY FRACTURED RESERVOIRS  

SciTech Connect (OSTI)

The objective of this project is to perform unique laboratory experiments with artificial fractured cores (AFCs) and X-ray CT to examine the physical mechanisms of bypassing in HFR and NFR that eventually result in more efficient CO{sub 2} flooding in heterogeneous or fracture-dominated reservoirs. To achieve this objective, we divided the report into two chapters. The first chapter was to image and perform experimental investigation of transfer mechanisms during CO{sub 2} flooding in NFR and HFR using X-ray CT scanner. In this chapter, we emphasized our work on understanding the connection between fracture properties and fundamentals of transfer mechanism from matrix to fractures and fluid flow through fracture systems. We started our work by investigating the effect of different overburden pressures and stress-state conditions on rock properties and fluid flow. Since the fracture aperture is one of important parameter that governs the fluid flow through the fracture systems, the average fracture aperture from the fluid flow experiments and fracture aperture distribution derived from X-ray CT scan were estimated for our modeling purposes. The fracture properties and fluid flow have significant changes in response to different overburden pressures and stress-state conditions. The fracture aperture distribution follows lognormal distribution even at elevated stress conditions. Later, we also investigated the fluid transfers between matrix and fracture that control imbibition process. We evaluated dimensionless time for validating the scheme of upscaling laboratory experiments to field dimensions. In CO{sub 2} injection experiments, the use of X-ray CT has allowed us to understand the mechanisms of CO{sub 2} flooding process in fractured system and to take important steps in reducing oil bypassed. When CO{sub 2} flooding experiments were performed on a short core with a fracture at the center of the core, the gravity plays an important role in the recovery of oil even in a short matrix block. This results are contrary with the previous believes that gravity drainage has always been associated with tall matrix blocks. In order to reduce oil bypassed, we injected water that has been viscosified with a polymer into the fracture to divert CO{sub 2} flow into matrix and delay CO{sub 2} breakthrough. Although the breakthrough time reduced considerably, water ''leak off'' into the matrix was very high. A cross-linked gel was used in the fracture to avoid this problem. The gel was found to overcome ''leak off'' problems and effectively divert CO{sub 2} flow into the matrix. As part of our technology transfer activity, we investigated the natural fracture aperture distribution of Tensleep formation cores. We found that the measured apertures distributions follow log normal distribution as expected. The second chapter deals with analysis and modeling the laboratory experiments and fluid flow through fractured networks. We derived a new equation to determine the average fracture aperture and the amount of each flow through fracture and matrix system. The results of this study were used as the observed data and for validating the simulation model. The idea behind this study is to validate the use of a set of smooth parallel plates that is common in modeling fracture system. The results suggest that fracture apertures need to be distributed to accurately model the experimental results. In order to study the imbibition process in details, we developed imbibition simulator. We validated our model with X-ray CT experimental data from different imbibition experiments. We found that the proper simulation model requires matching both weight gain and CT water saturation simultaneously as oppose to common practices in matching imbibition process with weight gain only because of lack information from CT scan. The work was continued by developing dual porosity simulation using empirical transfer function (ETF) derived from imbibition experiments. This allows reduction of uncertainty parameter in modeling transfer of fluids from matrix to the fra

Improved sweep efficiency through the application of horizontal well technology in a mature combustion EOR project: Battrum Field, Saskatchewan, Canada  

SciTech Connect (OSTI)

In-situ combustion has been employed in the Battrum field since 1964. Although the field has responded favorably to combustion, efficiency of the horizontal displacement process appears to be poor in some areas of the field. Injected air and combustion gases accumulate at the top of the reservoir, and injected water moves into a zone of relatively high mobile water saturation, occurring at the base of the reservoir. Rapid breakthrough of the injected fluids increases operating costs due to high gas-oil ratios. Placement of horizontal wells below the combustion gas cap, and conversion to a vertical displacement process is expected to increase oil rate, improve oil recovery, and reduce operating costs.

Improvement of Laser Damage Resistance and Diffraction Efficiency of Multilayer Dielectric Diffraction Gratings by HF-Etchback Linewidth Tailoring  

SciTech Connect (OSTI)

Multilayer dielectric (MLD) diffraction gratings for Petawatt-class laser systems possess unique laser damage characteristics. Details of the shape of the grating lines and the concentration of absorbing impurities on the surface of the grating structures both have strong effects on laser damage threshold. It is known that electric field enhancement in the solid material comprising the grating lines varies directly with the linewidth and inversely with the line height for equivalent diffraction efficiency. Here, they present an overview of laser damage characteristics of MLD gratings, and describe a process for post-processing ion-beam etched grating lines using very dilute buffered hydrofluoric acid solutions. This process acts simultaneously to reduce grating linewidth and remove surface contaminants, thereby improving laser damage thresholds through two pathways.

Technological developments to improve combustion efficiency and pollution control in coal-fired power stations in Japan  

SciTech Connect (OSTI)

In 1975, approximately 60 percent of all power generating facilities in Japan were oil fired. The oil crisis in the 1970s, however, led Japanese power utilities to utilize alternatives to oil as energy sources, including nuclear power, coal, LNG, and others. As a result, by 1990, the percentage of oil-fired power generation facilities had declined to approximately 31 percent. On the other hand, coal-fired power generation, which accounted for 5.7 percent of all facilities in 1975, increased its share to 7.5 percent in 1990 and is anticipated to expand further to 13 percent by the year 2000. In order to increase the utilization of coal-fired power generation facilities in Japan, it is necessary to work out thorough measures to protect the environment, mainly to control air pollution. The technologies that are able to do this are already available. The second issue is how to improve efficiency. In this chapter, I would like to introduce technological developments that improve efficiency and that protect the environment which have been implemented in coal-fired power stations in Japan. Examples of the former, include the atmospheric fluidized bed combustion (AFBC) boiler, the pressurized fluidized bed combustion (PFBC) boiler, and the ultra super-critical (USC) steam condition turbine, and an example of the latter is the dry deSOx/deNOx. Although details are not provided in this paper, there are also ongoing projects focusing on the development of technology for integrated gasification combined cycle generation, fuel cells and other systems undertaken by the government, i.e., the Ministry of International Trade and Industry (MITI), which is committed to the New Energy and Industrial Technology Development Organization (NEDO).

Improving water and energy metabolism efficiency in urban water supply system through pressure stabilization by optimal operation on water tanks  

Science Journals Connector (OSTI)

Abstract Water supply consumes 23% of the worldwide energy. Water distribution system, which accounts for 70% electricity consumption of water supply, is a key link of urban water and energy metabolism. The operation of the secondary water supply system (SWSS) has great influence on the pressure stability and associated energy consumption as well as water loss of urban water distribution. This research developed an approach based on the hydraulic solver EPANET and genetic algorithm (GA) to investigate the impacts of two different operation strategies, user demand regulation (UDR) and tank level regulation (TLR) of SWSS, on pressure stability and energy efficiency. The results showed that the strategy of TLR could reduce the pressure fluctuations and increase the minimal pressure of the distribution network under the same supplydemand condition. Reduction of the pressure fluctuations is beneficial to the reliability and leakage control of pipe networks. Increase of the minimal pressure indicates that less energy is lost during the distribution. Therefore, the TLR strategy of SWSS can support to initiatively lower the water pressure of the pumps at the water plant outlet, thus improves the water and energy metabolism efficiency in urban water supply system.

Improving PbS Quantum Dot Solar Cell Power Conversion Efficiency to an NREL-Certified 4.4% (Fact Sheet)  

SciTech Connect (OSTI)

Transition metal oxide improves overall efficiency and maintains performance with inexpensive metals. A research team at the National Renewable Energy Laboratory (NREL) has demonstrated that inserting a transition metal oxide (TMO) between the lead sulfide (PbS) quantum dot (QD) layer and the metal electrode eliminates the Schottky barrier that impedes efficient hole extraction and thereby improves the overall conversion efficiency. This allows for inexpensive metals such as Al to be employed without loss of performance. n-type TMOs consisting of molybdenum oxide (MoO{sub x}) and vanadium oxide (V{sub 2}O{sub x}) were used as an efficient hole extraction layer (HEL) in heterojunction ZnO/PbS QD solar cells. A 4.4% NREL-certified device was reported based on the MoO{sub x} HEL with Al as the back contact material, representing a more than 65% efficiency improvement compared with the case of Au contacting the PbS QD layer directly. The team finds the acting mechanism of the HEL to be a dipole formed at the MoO{sub x} and PbS interface, which enhances band bending to allow efficient hole extraction from the valence band of the PbS layer by MoO{sub x}. The carrier transport to the metal anode is likely enhanced through shallow gap states in the MoO{sub x} layer.

Origin of InGaN/GaN light-emitting diode efficiency improvements using tunnel-junction-cascaded active regions  

SciTech Connect (OSTI)

This Letter investigates the efficiency enhancement achieved by tunnel junction insertion into the InGaN/GaN multi-quantum well (MQW) active region of blue light emitting diodes (LEDs). The peak quantum efficiency of such LED exceeds 100%, but the maximum wall-plug efficiency (WPE) hardly changes. However, due to the increased bias, the WPE peaks at much higher input power, i.e., the WPE droop is significantly delayed, and the output power is strongly enhanced. The main physical reason for this improvement lies in the non-uniform vertical carrier distribution typically observed within InGaN MQWs.

Broadband Energy Harvesting Using a Metamaterial Resonator Embedded With Non-Foster Impedance Circuitry  

E-Print Network [OSTI]

Radio Frequency Identification (RFID) and implantable biomedical devices need efficient power and data transfer with very low profile antennas. We propose a low profile electrically small antenna for near-field wireless power and data telemetry employing a metamaterial Split Ring Resonator (SRR) antenna. SRRs can be designed for operation over wide frequencies from RF to visible. However, they are inherently narrowband making them sensitive to component mismatch with respect to external transmit antenna. Here we propose an embedding of a non-foster impedance circuitry into the metamaterial SRR structure that imparts conjugate negative complex impedance to this resonator antenna thereby increasing the effective bandwidth and thus overcoming the fundamental limit for efficient signal coupling. We demonstrate the concept through extensive numerical simulations and a prototype system at the board level using discrete off-the-shelf components and printed circuit SRR antenna at 500 MHz. We show that the power trans...

Potential use of feebate systems to foster environmentally sound urban waste management  

SciTech Connect (OSTI)

Waste treatment facilities are often shared among different municipalities as a means of managing wastes more efficiently. Usually, management costs are assigned to each municipality depending on the size of the population or total amount of waste produced, regardless of important environmental aspects such as per capita waste generation or achievements in composting or recycling. This paper presents a feebate (fee+rebate) system aimed to foster urban waste reduction and recovery. The proposal suggests that municipalities achieving better results in their waste management performance (from an ecological viewpoint) be recompensated with a rebate obtained from a fee charged to those municipalities that are less environmentally sound. This is a dynamic and flexible instrument that would positively encourage municipalities to reduce waste whilst increasing the recycling.

Abstract Here we demonstrate that elimination of ClaI restriction site from the sequence of a plasmid DNA increases the efficiency of transformation of Shewanella oneidensis MR-1 significantly. To achieve reliable transformation of S. oneidensis MR-1 plasmids either lacking ClaI site or isolated from primary transformants of S. oneidensis should be used.

Improved efficiency of miscible CO{sub 2} floods and enhanced prospects for CO{sub 2} flooding heterogeneous reservoirs. Annual report, April 18, 1995--April 17, 1996  

SciTech Connect (OSTI)

The overall goal of this project is to improve the efficiency of miscible CO{sub 2} floods and enhance the prospects for flooding heterogeneous reservoirs. This objective is being accomplished by extending experimental and modeling research in three task areas: (1) foams for selective mobility control in heterogeneous reservoirs, (2) reduction of the amount of CO{sub 2} required in CO{sub 2} floods, and (3) low IFT processes and the possibility of CO{sub 2} flooding in fractured reservoirs. This report provides results of the second year of the three-year project for each of the three task areas. In the first task, we are investigating a desirable characteristic of CO{sub 2}-foam called Selective Mobility Reduction (SMR) that results in an improvement in displacement efficiency by reducing the effects of reservoir heterogeneity. Research on SMR of foam during the past year has focused on three subjects: (1) to verify SMR in different rock permeabilities that are in capillary contact; (2) to test additional surfactants for the SMR property; and (3) to develop a modeling approach to assess the oil recovery efficiency of SMR in CO{sub 2}-foam on a reservoir scale. The experimental results from the composite cores suggest that the rock heterogeneity has significant effect on two phase (CO{sub 2}/brine) flow behavior in porous media, and that foam can favorably control CO{sub 2} mobility. The numerical modeling results suggest that foam with SMR can substantially increase the sweep efficiency and therefore improve oil recovery.

Energy Efficiency Improvement and Cost Saving Opportunities for the Fruit and Vegetable Processing Industry. An ENERGY STAR Guide for Energy and Plant Managers  

SciTech Connect (OSTI)

The U.S. fruit and vegetable processing industry--defined in this Energy Guide as facilities engaged in the canning, freezing, and drying or dehydrating of fruits and vegetables--consumes over $800 million worth of purchased fuels and electricity per year. Energy efficiency improvement isan important way to reduce these costs and to increase predictable earnings, especially in times of high energy price volatility. There are a variety of opportunities available at individual plants in the U.S. fruit and vegetable processing industry to reduce energy consumption in a cost-effective manner. This Energy Guide discusses energy efficiency practices and energy-efficient technologies that can be implemented at the component, process, facility, and organizational levels. A discussion of the trends, structure, and energy consumption characteristics of the U.S. fruit and vegetable processing industry is provided along with a description of the major process technologies used within the industry. Next, a wide variety of energy efficiency measures applicable to fruit and vegetable processing plants are described. Many measure descriptions include expected savings in energy and energy-related costs, based on case study data from real-world applications in fruit and vegetable processing facilities and related industries worldwide. Typical measure payback periods and references to further information in the technical literature are also provided, when available. Given the importance of water in fruit and vegetable processing, a summary of basic, proven measures for improving plant-level water efficiency are also provided. The information in this Energy Guide is intended to help energy and plant managers in the U.S. fruit and vegetable processing industry reduce energy and water consumption in a cost-effective manner while maintaining the quality of products manufactured. Further research on the economics of all measures--as well as on their applicability to different production practices--is needed to assess their cost effectiveness at individual plants.

The impact of environmental constraints on productivity improvement and energy efficiency in integrated paper and steel plants  

SciTech Connect (OSTI)

This paper presents a methodology and results for assessing the impact of production and energy efficiency, environmental regulation, and abatement capital expenditure constraints (e.g. capital rationing) on the productivity of energy and pollution intensive sectors. Energy is treated like any other production input when examining evidence of inefficiency. We find that capital rationing and environmental regulations do contribute to productivity and energy efficiency losses, but do not explain all of the production and energy inefficiencies observed in the paper industry. A summary of the energy source of production inefficiency found in the paper industry, is presented.. Each source is derived as the incremental contribution., i.e. the first is constraints on capital, the second in environmental regulation not accounted for by the first, and the final component is production inefficiency that is not accounted for my any of the- environmental analysis. While the methods are very data intensive, they reveal much more that analysis of aggregate data, 1835 since the only plant level data can provide the estimates of inefficiency that this methodology employs.

NERI Quarterly Progress Report -- April 1 - June 30, 2005 -- Development of a Supercritical Carbon Dioxide Brayton Cycle: Improving PBR Efficiency and Testing Material Compatibility  

SciTech Connect (OSTI)

The objective of this research is to improve a helium Brayton cycle and to develop a supercritical carbon dioxide Brayton cycle for the Pebble Bed Reactor (PBR) that can also be applied to the Fast Gas-Cooled Reactor (FGR) and the Very-High-Temperature Gas-Cooled Reactor (VHTR). The proposed supercritical carbon dioxide Brayton cycle will be used to improve the PBR, FGR, and VHTR net plant efficiency. Another objective of this research is to test materials to be used in the power conversion side at supercritical carbon dioxide conditions. Generally, the optimized Brayton cycle and balance of plant (BOP) to be developed from this study can be applied to Generation-IV reactor concepts. Particularly, we are interested in VHTR because it has a good chance of being built in the near future.

Semiconductor light-emitting devices having concave microstructures providing improved light extraction efficiency and method for producing same  

SciTech Connect (OSTI)

A conventional semiconductor LED is modified to include a microlens layer over its light-emitting surface. The LED may have an active layer including at least one quantum well layer of InGaN and GaN. The microlens layer includes a plurality of concave microstructures that cause light rays emanating from the LED to diffuse outwardly, leading to an increase in the light extraction efficiency of the LED. The concave microstructures may be arranged in a substantially uniform array, such as a close-packed hexagonal array. The microlens layer is preferably constructed of curable material, such as polydimethylsiloxane (PDMS), and is formed by soft-lithography imprinting by contacting fluid material of the microlens layer with a template bearing a monolayer of homogeneous microsphere crystals, to cause concave impressions, and then curing the material to fix the concave microstructures in the microlens layer and provide relatively uniform surface roughness.

3-Port Single-Stage PV & Battery Converter Improves Efficiency and Cost in Combined PV/Battery Systems  

SciTech Connect (OSTI)

Due to impressive cost reductions in recent years, photovoltaic (PV) generation is now able to produce electricity at highly competitive prices, but PVs inherent intermittency reduces the potential value of this energy. The integration of battery storage with PV will be transformational by increasing the value of solar. Utility scale systems will benefit by firming intermittency including PV ramp smoothing, grid support and load shifting, allowing PV to compete directly with conventional generation. For distributed grid-tied PV adding storage will reduce peak demand utility charges, as well as providing backup power during power grid failures. The largest long term impact of combined PV and battery systems may be for delivering reliable off-grid power to the billions of individuals globally without access to conventional power grids, or for billions more that suffer from daily power outages. PV module costs no longer dominate installed PV system costs. Balance-of-System (BOS) costs including the PV inverter and installation now contribute the majority of installed system costs. Battery costs are also dropping faster than installation and battery power converter systems. In each of these separate systems power converters have become a bottleneck for efficiency, cost and reliability. These bottlenecks are compounded in hybrid power conversion systems that combine separate PV and battery converters. Hybrid power conversion systems have required multiple power converters hardware units and multiple power conversion steps adding to efficiency losses, product and installation costs, and reliability issues. Ideal Power Converters has developed and patented a completely new theory of operation for electronic power converters using its indirect EnergyPacket Switching topology. It has established successful power converter products for both PV and battery systems, and its 3-Port Hybrid Converter is the first product to exploit the topologys capability for the industrys first single-stage multi-port hybrid power converter. This unique low cost approach eliminates the hybrid power conversion bottlenecks when integrating batteries into PV systems. As result this product will significantly accelerate market adoption of these systems.

USING LIGA BASED MICROFABRICATION TO IMPROVE OVERALL HEAT TRANSFER EFFICIENCY OF PRESSURIZED WATER REACTOR: I. Effects of Different Micro Pattern on Overall Heat Transfer.  

SciTech Connect (OSTI)

The Pressurized Water Reactors (PWRs in Figure 1) were originally developed for naval propulsion purposes, and then adapted to land-based applications. It has three parts: the reactor coolant system, the steam generator and the condenser. The Steam generator (a yellow area in Figure 1) is a shell and tube heat exchanger with high-pressure primary water passing through the tube side and lower pressure secondary feed water as well as steam passing through the shell side. Therefore, a key issue in increasing the efficiency of heat exchanger is to improve the design of steam generator, which is directly translated into economic benefits. The past research works show that the presence of a pin-fin array in a channel enhances the heat transfer significantly. Hence, using microfabrication techniques, such as LIGA, micro-molding or electroplating, some special microstructures can be fabricated around the tubes in the heat exchanger to increase the heat-exchanging efficiency and reduce the overall size of the heat-exchanger for the given heat transfer rates. In this paper, micro-pin fins of different densities made of SU-8 photoresist are fabricated and studied to evaluate overall heat transfer efficiency. The results show that there is an optimized micro pin-fin configuration that has the best overall heat transfer effects.
