    Progress is reported for a program whose goals are to demonstrate an experimental upgraded gas turbine powered automobile which meets the 1978 Federal Emissions Standards, has significantly improved fuel economy, and is competitive in performance, reliability, and potential manufacturing cost with the conventional piston engine powered, compact-size American automobile. Initial running of the upgraded engine took place on July 13, 1976. The engine proved to be mechanically sound, but was also 43% deficient in power. A continuing corrective development effort has to date reduced the power deficiency to 32%. Compressor efficiency was increased 2 points by changing to a 28-channel diffuser and tandem deswirl vanes; improved processing of seals has reduced regenerator leakage from about 5 to 2.5% of engine flow; a new compressor turbine nozzle has increased compressor turbine stage efficiency by about 1 point; and adjustments to burner mixing ports has reduced pressure drop from 2.8 to 2.1% of engine pressure. Key compressor turbine component improvements are scheduled for test during the next quarterly period. During the quarter, progress was also made on development of the Upgraded Vehicle control system; and instrumentation of the fourth program engine was completed by NASA. The engine will be used for development efforts at NASA LeRC.

    2016-04-01

    Flexible electronics has gained great interest in emerging wearable or rolling-up gadgets, such as foldable displays, electronic papers, and other personal multimedia devices. Subsequently, there is a need to develop energy storage devices that are pliable, inexpensive, and lightweight. Metal-air batteries have been identified as one of alternative energy storages for cost effective and high energy density applications. They offer cheaper production cost and higher energy density than most of the currently available battery technologies. Thus, they are promising candidates for flexible energy storage devices. Flexible metal-air batteries have to maintain their performances during various mechanical deformations. To date, efforts have been focused on fabricating flexible components for metal-air batteries. This review presents a brief introduction to the field, followed by progress on development of flexible electrolytes, electrodes, and prototype devices. Challenges and outlook towards the practical use of metal-air batteries are given in the last part.

    Efforts to improve electrochemical systems for space use relate to: (1) improvement of conventional systems; (2) development of fuel cells to practical power systems; and (3) a search for new systems that provide gains in energy density but offer comparable life and performance as conventional systems. Improvements in sealed conventional systems resulted in the areas of materials, charge control methods, cell operations and battery control, and specific process controls required during cell manufacture. Fuel-cell systems have been developed for spacecraft but the use of these power plants is limited. For present and planned flights, nickel-cadmium, silver-zinc, and silver-cadmium systems will be used. Improvements in nickel-cadmium batteries have been applied in medical and commercial areas.

  17. Fast Reactor Programme. Second Quarter 1969. Progress Report. RCN Report

    International Nuclear Information System (INIS)

    This progress report covers fast reactor research carried out by RCN during the second quarter 1969 forming part of the integrated fast breeder research and development programme also in progress at the national nuclear research centres Karlsruhe and Mol. The combined effort is based on a memorandum of co-operation in this field signed by the respective governments in 1968 and on a memorandum of understanding signed by the research centres. The RCN contribution is mainly concerned with the core of the fast breeder reactor and related safety aspects and, as such, must be looked upon as being complementary to the industrial research pro- field of fast reactors. The contribution comprises the following six items: - A Æéatîtôr , physics programme to determine the influence of fission products on several main characteristics of the reactor core such as void coefficient, Doppler coefficient and breeding ratio; - A fuel performance programme in which both stationary and transient irradiations are being carried out to establish the temperature and power limits of fuel rods; also the consequences of loss- of-cooling will be investigated; - Investigation into the change in mechanical properties of fuel canning materials due to high fast neutron doses; - A study of the corrosion behaviour of canning materials and their compatibility with the fuel under conditions of high temperature and high pressure; - Investigation into the behaviour of aerosols of fission products which could be formed after a fast reactor accident; a thorough understanding is of utmost importance for the reactor safety assessment ; - Studies on heat transfer in the reactor core. As fast breeders operate at high power densities, an accurate knowledge on the heat transfer phenomena is required

    OAK B188 A Novel Approach to Materials Development for Advanced Reactor Systems. Quarterly Progress Report, Year 1; Quarter 4. Year one of this project had three major goals. First, to specify, order and install a new high current ion source for more rapid and stable proton irradiation. Second, to assess the use of chromium pre-enrichment and hardening by combining cold-work and irradiation in an effort to isolate a radiation damage microstructure in stainless steel without the effects of RIS. Third, to initiate irradiation of reactor pressure vessel steel and Zircaloy. In year 1 quarter 4, the project goal was to begin characterization of the microstructure of model alloys of RPV steels irradiated over a range of doses. We also planned to prepare samples for microstructure isolation in stainless steels, and to receive and characterize Zircaloy samples for subsequent irradiation.

  4. Environmental surveillance program. Quarterly progress report, July--September, 1993

    International Nuclear Information System (INIS)

    This report contains data developed from monitoring site measurements and laboratory analyses of environmental samples that were collected during the period of July-September, 1993. Because some laboratory procedures are lengthy and could adversely affect the desired timeliness of reports, results of some analyses from this time period will be included in the next quarterly report. Quarterly reports, then, will be routine periodic documents that present continually updated information concerning the potential presence of environmental contaminants in the vicinity of the Idaho National Engineering Laboratory (INEL). During the third calendar quarter of 1993, Environmental Surveillance Program (ESP) measurements did not reveal unexpected levels of contaminants in any environmental samples measured or analyzed. Most of the results reported in this document are related to off-site air and ground water measurements. Future reports will include results of monitoring at additional locations and for additional environmental materials. Annual reports from the ESP will contain data generated during the previous four calendar quarters, and will display measurement trends for various combinations of locations, contaminants and environmental media. The annual report will also include more interpretive material and discussions than will normally be found in quarterly reports

    Full Text Available Are there many words combining both space and time? A quarter is one of such rare words: it means both a part of the city space and a period of the year. A regular city has parts bordered by four streets. For example, Chita is a city with an absolutely orthogonal historical center. This Utopian city was designed by Decembrists in the depth of Siberian ore-mines (120. The 130 Quarter in Irkutsk is irregular from its inception because of its triangular form. Located between two roads, the forked quarter was initially bordered by flows along the west-east axis – the main direction of the country. That is why it appreciated the gift for the 350 anniversary of its transit existence – a promenade for an unhurried flow of pedestrians. The quarter manages this flow quite well, while overcoming the difficulties of new existence and gathering myths (102. Arousing many expectations, the “Irkutsk’s Quarters” project continues the theme that was begun by the 130 Quarter and involved regeneration, revival and search for Genius Loci and the key to each single quarter (74. Beaded on the trading axis, these shabby and unfriendly quarters full of rubbish should be transformed for the good of inhabitants, guests and the small business. The triptych by Lidin, Rappaport and Nevlyutov is about happiness of urbanship and cities for people, too (58. The City Community Forum was also devoted to the urban theme (114. Going through the last quarter of the year, we hope that Irkutsk will keep to the right policy, so that in the near future the wooden downtown quarters will become its pride, and the design, construction and investment complexes will join in desire to increase the number of comfortable and lively quarters in our city. The Baikal Beam will get one more landmark: the Smart School (22 for Irkutsk’s children, including orphans, will be built in several years on the bank of Chertugeevsky Bay.

  10. The nuclear battery program: Progress and future possibilities

    International Nuclear Information System (INIS)

    The Nuclear Battery is an advanced small reactor being developed by Atomic Energy of Canada Limited (AECL) to produce electricity, and/or high-temperature steam heat, in locations remote form utility grids or natural gas pipelines. It features a novel passive primary heat transport system based on liquid-metal heat pipes, extraordinary passive safety based on the use of coated-particle fuel, and burnable neutron poisons in a solid graphite moderator. The reference design is capable of producing about 600 kW of electricity or about 2400 kW of steam heat in a base-load mode for 15 full-power years without refuelling. This paper reviews the technical progress, present activities and future goals of the Nuclear Battery R and D support program. Also, some of the alternate design approaches to increase the thermal power output from the Nuclear Battery and, hence, to further reduce its unit energy cost, are briefly outlined and compared.

  6. Progress and prospective of solid-state lithium batteries

    International Nuclear Information System (INIS)

    The development of lithium-ion batteries has energized studies of solid-state batteries, because the non-flammability of their solid electrolytes offers a fundamental solution to safety concerns. Since poor ionic conduction in solid electrolytes is a major drawback in solid-state batteries, such studies have been focused on the enhancement of ionic conductivity. The studies have identified some high performance solid electrolytes; however, some disadvantages have remained hidden until their use in batteries. This paper reviews the development of solid electrolytes and their application to solid-state lithium batteries

    Progress is reported for a research program to demonstrate an experimental gas turbine powered automobile which would meet the 1978 Federal Emissions Standards, have significantly improved fuel economy and be competitive in performance, reliability and potential manufacturing cost with the conventional piston engine powered, standard size American automobile. Chrysler Corporation's Sixth Generation Gas Turbine Engine, having been selected as most representative of the state-of-the-art at the beginning of this program, has been used as the Baseline Engine. This is a 4:1 pressure ratio regenerative engine with variable power turbine nozzles which meets the .41 HC, 3.4 CO, 3.0 NOx grams/mile original 1975 emissions standards. Baseline vehicles are intermediate-size, 4-door sedans modified to accept the turbine engines. The Baseline cars are being actively utilized in a variety of Bicentennial/Energy related displays and demonstrations. All Baseline Engine improvement tasks have been completed. Emissions tests using COED coal derived fuel were conducted. The first Upgraded Engine was assembled, installed in a test cell, and initial test runs up to 70% speed were conducted. Control of the gas generator shaft instabilities which have resulted in failures of the gas lubricated bearing, was demonstrated by providing a low spring rate, squeeze film damping, and reducing the motion restraint caused by thrust loadings. The power turbine shaft dynamics fixture was run successfully to 60,000 rpm. Conversion of the production cars for the Upgraded Engine is continuing. The two four-door cars are nearly complete.

    Ferreira, Summer Rhodes; Shane, Rodney (East Penn Manufacturing, Lyon Station, PA); Enos, David George

    2011-10-01

    This report describes the status of research being performed under CRADA No. SC10/01771.00 (Lead/Carbon Functionality in VRLA Batteries) between Sandia National Laboratories and East Penn Manufacturing, conducted for the U.S. Department of Energy's Energy Storage Systems Program. The Quarter 4 Milestone was completed on time. The milestone entails the initiation of high rate, partial state of charge (HRPSoC) cycling of the carbon enhanced batteries. The morphology, porosity, and porosity distribution within the plates after 1k and 10k cycles were documented, illustrating the changes which take place in the early life of the carbon containing batteries, and as the battery approaches failure due to hard sulfation for the control battery. Longer term cycling on a subset of the received East Penn cells containing different carbons (and a control) continues, and will progress into FY12. Carbon has been explored as an addition to lead-acid battery electrodes in a number of ways. Perhaps the most notable to date has been the hybrid 'Ultrabattery' developed by CSIRO where an asymmetric carbon-based electrochemical capacitor is combined with a lead-acid battery into a single cell, dramatically improving high-rate partial-state-of-charge (HRPSoC) operation. As illustrated below, the 'Ultrabattery' is a hybrid device constructed using a traditional lead-acid battery positive plate (i.e., PbO2) and a negative electrode consisting of a carbon electrode in parallel with a lead-acid negative plate. This device exhibits a dramatically improved cycle life over traditional VRLA batteries, as well as increased charge power and charge acceptance. The 'Ultrabattery' has been produced successfully by both The Furukawa Battery Co. and East Penn Manufacturing. An example illustrating the dramatic improvement in cycle life of the Ultrabattery over a conventional VRLA battery is shown in a graph. In addition to the aforementioned hybrid device, carbon has

  15. Redox flow batteries for hybrid electric vehicles: progress and challenges

    OpenAIRE

    2009-01-01

    Electric vehicles have been the focus of muchresearch over the last two decades as the world has sought improved energy utilization and reduced emissions. However, the lengthy charging time, modest range and relatively sluggish performance of batteries have restricted the commercialization of electric vehicles. Hybrid propulsion can overcome most of these shortcomings, with improved energy efficiency and reduced emissions compared to conventional internal combustion engine vehicles (ICEVs)...

  16. Electrochemical energy — progress towards a cleaner future: lead/acid batteries and the competition

    Science.gov (United States)

    Appleby, A. J.

    Electric vehicles (EVs) with conventional architecture may be capable of a range of 72-80 km (45-50 miles) with a 35 Wh kg -1 lead/acid battery with a weight equal to 25% of that of the vehicle. An improved vehicle (such as the GM Impact) with lower energy utilization and architecture that allows greater battery weight may attain 160 km (100 miles). A battery corresponding to the mid-term goal of the US Advanced Battery Consortium in an Impact-type vehicle could allow 480 km (300 miles) range. It remains to be seen if this will be technically and economically attained. The EV is more likely to be made practical with the development of a satisfactory polymer-exchange-membrane (PEM) fuel cell, which will involve the same recharging logistics as those of a gasoline vehicle, with much improved energy efficiency. Considerable progress is still required, but one major problem, the amount of platinum catalyst required per vehicle, appears to have been overcome. A loading of 0.15 g/kW now appears to be feasible, so major production of such vehicles will allow platinum producers to keep pace. The advent of the PEM-fuel-cell/battery hybrid vehicle wiil open up a larger market for rechargeable bateries than that for vehicles which use traction batteries alone. Economics seem to point to the fact that such vehicles will use lead/acid batteries for the hybrid peak power and regenerative braking element.

This will entail the design, construction, installation, and use of a flexible test facility which can operate under realistic gasification and combustion conditions. The major particulate control device issues to be addressed include the integration of the particulate control devices into coal utilization systems, on-line cleaning techniques, chemical and thermal degradation of components, fatigue or structural failures, blinding, collection efficiency as a function of particle size, and scaleup of particulate control systems to commercial size. The conceptual design of the facility was extended to include a within scope, phased expansion of the existing Hot Gas Cleanup Test Facility Cooperative Agreement to also address systems integration issues of hot particulate removal in advanced coal-based power generation systems. This expansion included the consideration of the following modules at the test facility in addition to the existing Transport Reactor gas source and Hot Gas Cleanup Units: Carbonizer/Pressurized Circulating Fluidized Bed Gas Source. Hot Gas Cleanup Units to mate to all gas streams; Combustion Gas Turbine; and Fuel Cell and associated gas treatment. This expansion to the Hot Gas Cleanup Test Facility is herein referred to as the Power Systems Development Facility (PSDF). The major emphasis during this reporting period was continuing the detailed design of the facility.

    Electrical energy storage and conversion is vital to a clean, sustainable, and secure energy future. Among all electrochemical energy storage devices, metal-air batteries have potential to offer the highest energy density, representing the most promising systems for portable (electronics), mobile (electrical vehicles), and stationary (micro-grids) applications. To date, however, many fundamental issues are yet to be overcome to realize this potential. For example, efficient catalysts for oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) at the air-electrode are yet to be developed to significantly reduce the polarization loss in metal-air batteries, which severely hinders the rate capability, energy efficiency, and operational life. In this progress report, a brief overview is first presented of the critical issues relevant to air-electrodes in metal-air batteries. Some recent advancements in the development of non-precious catalysts for ORR in Li-air and Zn-air batteries are then highlighted, including transition metal oxides, low-dimensional carbon-based structures, and other catalysts such as transition-metal macrocycles and metal nitrides. New directions and future perspectives for metal-air batteries are also outlined. (Copyright copyright 2012 WILEY-VCH Verlag GmbH and Co. KGaA, Weinheim)

    This is the first in a series of quarterly progress reports covering activities at ORNL to develop thermal energy storage (TES) technology applicable to building heating and cooling. Studies to be carried out will emphasize latent heat storage in that sensible heat storage is held to be an essentially existing technology. Development of a time-dependent analytical model of a TES system charged with a phase-change material was started. A report on TES subsystems for application to solar energy sources is nearing completion. Studies into the physical chemistry of TES materials were initiated. Preliminary data were obtained on the melt-freeze cycle behavior and viscosities of sodium thiosulfate pentahydrate and a mixture of Glauber's salt and Borax; limited melt-freeze data were obtained on two paraffin waxes. A subcontract was signed with Monsanto Research Corporation for studies on form-stable crystalline polymer pellets for TES; subcontracts are being negotiated with four other organizations (Clemson University, Dow Chemical Company, Franklin Institute, and Suntek Research Associates). Review of 10 of 13 unsolicited proposals received was completed by the end of June 1976.

    Energy Technology Data Exchange (ETDEWEB)

    1992-03-01

    The Magnetohydrodynamics (MHD) Integrated Topping Cycle (ITC) Project represents the culmination of the proof-of-concept (POC) development stage in the US Department of Energy (DOE) program to advance MHD technology to early commercial development stage utility power applications. The project is a joint effort, combining the skills of three topping cycle component developers: TRW, Avco/TDS, and Westinghouse. TRW, the prime contractor and system integrator, is responsible for the 50 thermal megawatt (50 MW{sub t}) slagging coal combustion subsystem. Avco/TDS is responsible for the MHD channel subsystem (nozzle, channel, diffuser, and power conditioning circuits), and Westinghouse is responsible for the current consolidation subsystem. The ITC Project will advance the state-of-the-art in MHD power systems with the design, construction, and integrated testing of 50 MW{sub t} power train components which are prototypical of the equipment that will be used in an early commercial scale MHD utility retrofit. Long duration testing of the integrated power train at the Component Development and Integration Facility (CDIF) in Butte, Montana will be performed, so that by the early 1990`s, an engineering data base on the reliability, availability, maintainability and performance of the system will be available to allow scaleup of the prototypical designs to the next development level. This Sixteenth Quarterly Technical Progress Report covers the period May 1, 1991 to July 31, 1991.

    1981-01-01

    This report summarizes the progress of the Solvent Refined Coal (SRC) project at the SRC Pilot Plant in Fort Lewis, Wahsington, and the Process Development Unit (P-99) in Harmarville, Pennsylvania. After the remaining runs of the slurry preheater survey test program were completed January 14, the Fort Lewis Pilot Plant was shut down to inspect Slurry Preheater B and to insulate the coil for future testing at higher rates of heat flux. Radiographic inspection of the coil showed that the welds at the pressure taps and the immersion thermowells did not meet design specifications. Slurry Preheater A was used during the first 12 days of February while weld repairs and modifications to Slurry Preheater B were completed. Two attempts to complete a material balance run on Powhatan No. 6 Mine coal were attempted but neither was successful. Slurry Preheater B was in service the remainder of the quarter. The start of a series of runs at higher heat flux was delayed because of plugging in both the slurry and the hydrogen flow metering systems. Three baseline runs and three slurry runs of the high heat flux program were completed before the plant was shut down March 12 for repair of the Inert Gas Unit. Attempts to complete a fourth slurry run at high heat flux were unsuccessful because of problems with the coal feed handling and the vortex mix systems. Process Development Unit (P-99) completed three of the four runs designed to study the effect of dissolver L/D ratio. The fourth was under way at the end of the period. SRC yield correlations have been developed that include coal properties as independent variables. A preliminary ranking of coals according to their reactivity in PDU P-99 has been made. Techniques for studying coking phenomenona are now in place.

  13. Fusion-driven actinide burner design study. Second quarterly progress report

    International Nuclear Information System (INIS)

    The Second Quarterly Progress Report summarizes the status at the mid-point of the conceptual design effort. The fusion driver continues to pose some of the principal design problems due to the necessity of advancing plasma engineering and technology for long pulse, high duty cycle operation. The development of credible design solutions to these problems is one of the major objectives of the study. The TF and OH coil designs have been modified to provide a more compact arrangement in the nose region of the TF coils and to ensure fully cryostable operation. A unique concept has been developed to effectively shield the TF coils from the poloidal fields. A vacuum vessel concept which separates the functions for sustaining the differential pressure load and for sealing the vacuum system is described. The thickness of the blanket has been decreased to reduce the power density and the actinide inventory. Determination and presentation of actinide depletion characteristics represents a major element thus far in the study and is a principal objective. Evaluation of the changes in the hazard only during irradiation proved to be an inadequate measure of the reduction in long term hazards due to the importance of radioactive daughter products which appear much later in time. Therefore, comparisons have been made of long term decay characteristics before and after irradiation in the actinide burner. It has also been noted that some of the actinides that are produced during irradiation have beneficial applications as radioisotopic power sources. These and other considerations suggest that alternate approaches to assessing the waste management problem be considered to develop a meaningful perspective on long term hazards from the actinides

  15. Methyl chloride via oxyhydrochlorination of methane. Quarterly technical progress report No. 7, April--June 1993

    Energy Technology Data Exchange (ETDEWEB)

    1994-01-01

    The purpose of this contract is to develop a process for converting light alkane gases to methyl chloride via oxyhydrochlorination using highly selective, stable catalysts in fixed-bed reactors designed to remove the large amount of heat generated, so as to control the reaction temperature. Further, the objective is to obtain the engineering data base necessary for developing a commercially feasible process and to evaluate the economics of the process. Several key technology areas were evaluated this quarter. The catalyst definition effort focused on the determination of the role of the Li and La promoters that have been found to be useful in enhancing Cu based oxyhydrochlorination of methane catalysts. Initial experiments show that the La acts to provide a much more active catalyst than the Cu only case. The role of the Li is ambiguous at this point. The Li enhances the stability of the La promoted catalyst, but gives only marginal improvement by itself This work will be continued, with additional emphasis on the analysis of the catalysts to determine the structural role that the promoters may play. The separation unit operation definition made significant progress by demonstrating in a laboratory system that a process solvent may be used to remove the product CH{sub 3}Cl from the reactor effluent stream. To date the data has been qualitative, but clear. Work will continue to gather the information possible in the laboratory to help with PDU design. An extensive amount of testing was performed on the chosen process solvent, Multitherm. A comprehensive review of all the thermal testing and associated FTIR, UV/VIS, and physical property testing is included in this report. This work shows that Multitherm should give the desired stability and solubility that are necessary to make the separation unit operation successful.

    1995-07-01

    On September 30, 1993, the U.S. Department of Energy-Morgantown Energy Technology Center and Southern Illinois University at Carbondale (SIUC) entered into a cooperative research agreement entitled {open_quotes}Management of Dry Flue Gas Desulfurization By-Products in Underground Mines{close_quotes} (DE-FC21-93MC30252). Under the agreement Southern Illinois University at Carbondale will develop and demonstrate several technologies for the placement of coal combustion residues in abandoned coal mines, and will assess the environmental impact of such underground residues placement. Previous quarterly Technical Progress Reports have set forth the specific objectives of the program, and a discussion of these is not repeated here. Rather, this report discusses the technical progress made during the period April 1 - June 30, 1995. A final topical report on the SEEC, Inc. demonstration of its technology for the transporting of coal combustion residues was completed during the quarter, although final printing of the report was accomplished early in July, 1995. The SEEC technology involves the use of Collapsible Intermodal Containers (CIC`s) developed by SEEC, and the transportation of such containers - filled with fly ash or other coal combustion residues - on rail coal cars or other transportation means. Copies of the final topical report, entitled {open_quotes}The Development and Testing of Collapsible Intermodal Containers for the Handling and Transport of Coal Combustion Residues{close_quotes} were furnished to the Morgantown Energy Technology Center. The Rapid Aging Test colums were placed in operation during the quarter. This test is to determine the long-term reaction of both the pneumatic and hydraulic mixtures to brine as a leaching material, and simulates the conditions that will be encountered in the actual underground placement of the coal combustion residues mixtures. The tests will continue for about one year.

    This is the fourth combined quarterly progress report for those projects that are part of the Advanced Research and Technology Development Fossil Energy Materials Program. The objective is to conduct a program of research and development on materials for fossil energy applications with a focus on the longer-term and generic needs of the various fossil fuel technologies. The program includes research aimed toward a better understanding of materials behavior in fossil energy environments and the development of new materials capable of substantial enhancement of plant operations and reliability. Work performed on the program generally falls into the Applied Research and Exploratory Development categories as defined in the DOE Technology Base Review, although basic research and engineering development are also conducted. A substantial portion of the work on the AR and TD Fossil Energy Materials Program is performed by participating cntractor organizations. All subcontractor work is monitored by Program staff members at ORNL and Argonne National Laboratory. This report is organized in accordance with a work breakdown structure defined in the AR and TD Fossil Energy Materials Program Plan for FY 1981 in which projects are organized according to fossil energy technologies. We hope this series of AR and TD Fossil Energy Materials Program quarterly progress reports will aid in the dissemination of information developed on the program.

    This project was established with a new interagency agreement between the Department of Energy and the Department of Transportation to provide collaborative research, development, and benchmarking of advanced three-dimensional computational mechanics analysis methods to the aerodynamics and hydraulics laboratories at the Turner-Fairbank Highway Research Center for a period of five years, beginning in October 2010. The analysis methods employ well-benchmarked and supported commercial computational mechanics software. Computational mechanics encompasses the areas of Computational Fluid Dynamics (CFD), Computational Wind Engineering (CWE), Computational Structural Mechanics (CSM), and Computational Multiphysics Mechanics (CMM) applied in Fluid-Structure Interaction (FSI) problems. The major areas of focus of the project are wind and water loads on bridges - superstructure, deck, cables, and substructure (including soil), primarily during storms and flood events - and the risks that these loads pose to structural failure. For flood events at bridges, another major focus of the work is assessment of the risk to bridges caused by scour of stream and riverbed material away from the foundations of a bridge. Other areas of current research include modeling of flow through culverts to assess them for fish passage, modeling of the salt spray transport into bridge girders to address suitability of using weathering steel in bridges, vehicle stability under high wind loading, and the use of electromagnetic shock absorbers to improve vehicle stability under high wind conditions. This quarterly report documents technical progress on the project tasks for the period of January through March 2011.

The sub-tasks are grouped into two categories: Category 1 consists of those sub-tasks which are directly related to fuel economy and Category 2 consists of those sub-tasks which are not directly related to fuel economy but are an integral part of the Task I effort.

  16. Review on recent progress of nanostructured anode materials for Li-ion batteries

    KAUST Repository

    Goriparti, Subrahmanyam

    2014-07-01

    This review highlights the recent research advances in active nanostructured anode materials for the next generation of Li-ion batteries (LIBs). In fact, in order to address both energy and power demands of secondary LIBs for future energy storage applications, it is required the development of innovative kinds of electrodes. Nanostructured materials based on carbon, metal/semiconductor, metal oxides and metal phosphides/nitrides/sulfides show a variety of admirable properties for LIBs applications such as high surface area, low diffusion distance, high electrical and ionic conductivity. Therefore, nanosized active materials are extremely promising for bridging the gap towards the realization of the next generation of LIBs with high reversible capacities, increased power capability, long cycling stability and free from safety concerns. In this review, anode materials are classified, depending on their electrochemical reaction with lithium, into three groups: intercalation/de-intercalation, alloy/de-alloy and conversion materials. Furthermore, the effect of nanoscale size and morphology on the electrochemical performance is presented. Synthesis of the nanostructures, lithium battery performance and electrode reaction mechanisms are also discussed. To conclude, the main aim of this review is to provide an organic outline of the wide range of recent research progresses and perspectives on nanosized active anode materials for future LIBs.

    This project is a major step in the Department of Energy`s program to show that ultra-clean coal-water slurry fuel (CWF) can be produced from selected coals and that this premium fuel will be a cost-effective replacement for oil and natural gas now fueling some of the industrial and utility boilers in the United States. The replacement of oil and gas with CWF can only be realized if retrofit costs are kept to a minimum and retrofit boiler emissions meet national goals for clean air. These concerns establish the specifications for maximum ash and sulfur levels and combustion properties of the CWF. This cost-share contract is a 48-month program which started on September 30, 1992. This report discusses the technical progress made during the 4th quarter of the project from July 1 to September 30, 1993.

The mission of this work is to devise a new catalyst which can be used in a simple economic process to convert the light alkanes in natural gas to oxygenate products that can either be used as clean-burning, high octane liquid fuels, as fuel components or as precursors to liquid hydrocarbon uwspomdon fuel. During the past quarter we have continued to design, prepare, characterize and test novel catalysts for the mild selective reaction of light hydrocarbons with air or oxygen to produce alcohols directly. These catalysts are designed to form active metal oxo (MO) species and to be uniquely active for the homolytic cleavage of the carbon-hydrogen bonds in light alkanes producing intermediates which can form alcohols. We continue to investigate three molecular environments for the active catalytic species that we are trying to generate: electron-deficient macrocycles (PHASE I), polyoxometallates (PHASE II), and regular oxidic lattices including zeolites and related structures as well as other molecular surface structures having metal oxo groups (PHASE I).

  20. Study on reduction of accessory horsepower requirements. Fourth quarterly progress report

    Energy Technology Data Exchange (ETDEWEB)

    1975-07-30

    The program objective is to evolve and define an accessory drive system that will minimize system power consumption of driven accessories on an internal combustion engine in a passenger automobile. The initial three program phases established concept feasibility, determined potential fuel savings, and selected a drive system design for concept mechanization. During this quarter the major program accomplishments were: selection of candidate belt-drive concepts; completion of Phase III baseline vehicle drive systems physical and operational envelopes; completion of analysis for a mechanically controlled direct-operated belt drive with input programming; and completion of design layout and analysis for a hydromechanically controlled, servo-operated belt drive with output-speed sensing.

    The progress in this quarter includes four parts. In the first segment, the implications of our data reported in the List quarter are discussed further. BET N{sub 2} surface area does not seems to be the only contributing factor to the remarkable activity of lignite char during reburning, and chars of different origins probably have different controlling steps in the overall surface reaction mechanisms. Unlike NO reduction in the gas phase, oxygen inhibits the heterogeneous mechanisms. The second part of this report justifies the use of our laminar flow reactor system for the measurement of reaction rate. Dispersion model is used in the analysis. An expression relating the rate constant with the experimentally obtainable NO conversion for our flow reactor have been derived. Rates of NO/char reaction for six series of experiments have been measured over the temperature range 800 to 1100{degrees}C. These six series of experiments have been conducted with two different chars, one bituminous coal char and one lignite char, and three different levels of feed NO concentrations, 200, 400 and 1000 ppm. Results from the comparison of char activities suggest that, in the absence of O{sub 2} and CO{sub 2}, the origin of char is not a significant factor for NO reduction. The CO/CO{sub 2} ratio in the products is higher than one under all test conditions, but the ratio increases with increasing feed NO concentrations. Recoveries of oxygen form the lignite char at temperatures above 1050{degrees}C is higher than 1 indicating gasification of organic oxygen in the char. Surface areas of selected chars after devolatilization and after reburning have been analyzed by BET in N{sub 2}. Results indicated char surface area changes after reburning, which is caused either by the higher temperature of reburning or by surface reaction.

    1985-08-01

    This report covers the progress of the Short Rotation Woody Crops Program (SRWCP) during the third quarter of fiscal year 1985. This report summarizes ORNL management activities, technical activities at ORNL and subcontract institutions, and the technology transfer that is occurring as a result of subcontractor and ORNL activities. Third-year results of a nutrient utilization study confirmed that there were no benefits to quarterly fertilization with urea nitrogen. Testing of one prototype short-rotation intensive culture harvester was conducted on a sycamore plantation on Scott Paper Company land in southern Alabama. Coppice yields of European black alder reported by Iowa State University indicate potential productivity of about 7.2 dry Mg . ha/sup -1/ . year/sup -1/ if the best trees are selected. Coppice yields were more than double first-rotation yields. About 31,000 black locust and larch trees were established in 12 genetic tests at 4 sites in Michigan. Seedling rotation productivity rates of 4-year-old hybrid poplar, based on harvest data, were reported by Pennsylvania State University. Rates varied from 4.8 dry Mg . ha/sup -1/ . year/sup -1/ to 10.7 dry Mg . ha/sup -1/ . year/sup -1/, depending on site, management strategy, and planting year. An efficient method for in vitro micropropagation of elite genotypes of fourwing saltbush was developed by Plant Resources Institute. A new study to evaluate yield/density relationships was established by the USDA Forest Service, Pacific Northwest Forest and Range Experiment Station. Dissertation research on the crown geometry of plantation-grown American sycamore was completed.

  7. Healy clean coal project: Technical progress report. Quarterly report number 14, April--June 1994

    Energy Technology Data Exchange (ETDEWEB)

    1994-07-01

    The primary objective of the HCCP is to demonstrate a new power plant design integrating an advanced combustor and heat recovery system coupled with both high and low temperature emission control processes. Alaskan bituminous and subbituminous coals will be the fuels. Emissions of SO{sub 2} and NO{sub x} from the plant will be controlled using a slagging coal combustor with limestone injection, in conjunction with a boiler. Further SO{sub 2} and particulate removal will be accomplished using an Activated Recycle Spray Absorber System. Environmental efforts during this quarter concentrated on supporting the Alaska Department of Environmental Conservation`s (ADEC) insurance of the Final Prevention of Significant Deterioration (PSD)/Permit to Operate, preparation of post-construction Air Quality Monitoring and Visibility Monitoring Plans, preparation of a General Wastewater Discharge Permit Application for disposal of wastewater from on-site excavations, review of a PreDraft National Pollutant Discharge Elimination System (NPDES) Permit and Fact Sheet and discussions with the Environmental Protection Agency (EPA) and ADEC on NPDES Permit limitations, and preparation of a draft Storm Water Pollution Prevention Plan for HCCP construction. The final PSD/Permit to Operate No. 9431-AA001 and Technical Analysis Report (TAR) was issued on May 12, 1994. Finalization of engineering and design continued on the boiler, combustors, flue gas desulfurization (FGD), and turbine/generator systems and balance of plant.

    Stephens, D.R.; Clements, W. (eds.)

    1981-11-09

    We have continued our laboratory studies of forward gasification in small blocks of coal mounted in 55-gal drums. A steam/oxygen mixture is fed into a small hole drilled longitudinally through the center of the block, the coal is ignited near the inlet and burns toward the outlet, and the product gases come off at the outlet. Various diagnostic measurements are made during the course of the burn, and afterward the coal block is split open so that the cavity can be examined. Development work continues on our mathematical model for the small coal block experiments. Preparations for the large block experiments at a coal outcrop in the Tono Basin of Washington State have required steadily increasing effort with the approach of the scheduled starting time for the experiments (Fall 1981). Also in preparation is the deep gasification experiment, Tono 1, planned for another site in the Tono Basin after the large block experiments have been completed. Wrap-up work continues on our previous gasification experiments in Wyoming. Results of the postburn core-drilling program Hoe Creek 3 are presented here. Since 1976 the Soviets have been granted four US patents on various aspects of the underground coal gasification process. These patents are described here, and techniques of special interest are noted. Finally, we include ten abstracts of pertinent LLNL reports and papers completed during the quarter.

  9. Physical protection of nuclear materials in transit. Quarterly progress report, April--June 1978

    International Nuclear Information System (INIS)

    A computer model, SOURCE, has been developed to study the impact of convoy configuration and tactics upon personnel survival and emergency signal generation during an initial armed attack. During this quarter, several improvements were made to the SOURCE code. These improvements include (1) the capability to model an ambush in which the adversaries set up a roadblock, (2) upgraded data on aiming accuracies and human vulnerabilities, and (3) two output formats for examining the locations of the surviving guards. To support the conflict analysis task, several complementary conflict modeling efforts are undergoing parallel development. These methodologies include the SABRES computerized conflict simulation models, the AMBUSH conflict board game, and an alternative methodology being developed by Vector Research, Inc. (VRI). The SABRES I combat model can be used to study the relative value of alternative defender tactics and the relative value of different weapon systems. AMBUSH is a tactical board game which provides a hypothetical conflict between a truck convoy and an adversary group attempting a hijacking. ORINCON Corporation developed network models to be used in determining the cost implications of alternative transportation regulations. SRI International provided weapon characterization data from representative types and calibers of sporting rifles, assault rifles, machine guns, submachine guns, shotguns, and handguns. The alternative methodology for conflict modeling being developed by VRI is the engagement model, CONVOY. SAI is under contract to model the communication system for transporters of SNM

  10. Consolidated fuel-reprocessing program. Quarterly progress report for the period ending November 30, 1980

    International Nuclear Information System (INIS)

    Large-scale crushing and burning tests of fuel received from the Federal Republic of Germany (FRG) have identified differences in processing characteristics. The NO/sub x/ converter experimental tests continued this quarter in the GA off-gas system. The dependence of nitric oxide conversion efficiency on ammonia and oxygen concentrations has been determined. An optimum ratio of ammonia to nitric oxide was identified in terms of the conversion factor for nitrix oxide. No residual ammonia was detected downstream of the NO/sub x/ converter. Design of the radon source subsystem and fabrication of the radon source assembly and shielded radon source containment were completed. Second-thorium-cycle column tests confirm the feasibility of producing thorium product having acceptably low uranium contents. Two axial mixing tests were completed on the thorium extraction section. The Mott inertial filter tests continued. The dissolution rate of HTGR fuel spheres is speeded by a factor of three by using an airlift acid recirculator to improve ThO2-dissolvent contact. The FRG HTGR fuel spheres dissolve a factor of three more slowly than the sol-gel derived ThO2 spheres. The task group completed a thorium transfer kinetics comparison of alternative solvents. Hydrolysis studies were started on alternative solvents

  3. Exxon catalytic coal gasification process development program. Quarterly technical progress report, January 1-March 31, 1979

    1979-05-01

    This report covers the activites for the Exxon Catalytic Coal Gasification Development Program during the quarter January 1-March 31, 1979. Construction of a bench apparatus to study reactions of product and recycle gas in furnace and heat exchanger tubes was completed and checkout of the apparatus was begun. A Startup and Initial Operation Schedule, a Checkout Test Plan, and an Initial Startup Plan were developed for the Process Develoment Unit (PDU). The PDU will be started up in a sequential manner, with the gasification system being started up on a once-through basis first. The gas separation system will be started up next, followed by the catalyst recovery system. The programmable controller, which handles valve sequencing, alarming, and other miscellaneous functions on the PDU, was programmed and checkout was completed on the coal feed, gas feed, and filter systems. Work continued on defining the cause of the breakdown of char and lime during digestion in the prototype catalyst recovery unit. It was concluded that both the lime and char particles are fragile and will break down to fines if handled roughly. Removal of the potassium from the char by water washing does not cause the char particles to disintegrate. The perferred processing sequence for catalyst recovery in the PDU has been identified. Bench scale tests confirmed that the change in catalyst from K/sub 2/CO/sub 3/ to KOH was not responsible for the differences in fluidized bed densities between the present and the predevelopment operations of the FBG. Work was completed on a revised offsites facilities definition and cost estimate to update the CCG Commercial Plant Study Design prepared during the predevelopment program.

    The performance of the third type of catalytic membrane reactor configuration, with catalyst deposited in the membrane and no catalyst or inert materials in the tube side, was evaluated. The C{sub 2} selectivity obtained was about 10% due to the gas phase reaction in the empty tube side of the reactor. The membrane reactor with an oxygen-permeable dense membrane has been built. The use of a dense membrane will eliminate the loss of hydrocarbon from the tube side to the shell side, as observed in the Vycor glass membrane reactor. Also, air can be used as the oxygen source without contaminating the product. La/MgO was synthesized and will be used as the catalyst for the dense membrane reactor. This catalyst was reported in the literature to show significant improvement of C{sub 2} selectivity and yield for oxidative coupling of methane in a packed-bed reactor by using the operation mode of staged-feed of oxygen. A reactor mode for methane oxidative coupling in reactors with both distributed oxygen feed and C{sub 2} product removal was developed based on the general model of cross-flow reactors reported in the last quarterly report. A distributed oxygen feed could give rise to much higher C{sub 2} yield than the co-feed reactor as long as the space time is long enough. In the case of a two-membrane reactor, where oxygen is supplied by one membrane and products are removed through the other membrane, a high separation factor of C{sub 2} product to methane for the product-removal membrane is critical to achieve high C{sub 2} yield.

  5. Quarterly technical progress report for the period ending June 30, 1984

    1984-10-01

    The Magnetohydrodynamics Program (Component Development and Integration Facility) in Butte, Montana, continued its site preparation for the TRW first-stage combustor installation. In the area of flue gas cleanup, our in-house research program is continuing its investigation into the causes of sorbent attrition in PETC's fluidized-bed copper oxide process for simultaneous SO/sub 2//NO/sub x/ removal. Interwoven with these tests is a series of spray dryer/electrostatic precipitator tests that are being conducted with the cooperation of Wheelabrator-Frye, Inc. This test series was completed this quarter, and the data show that when using a Kentucky coal, Wheelabrator-Frye's electrostatic precipitator provides excellent particulate control efficiency while using a spray dryer for sulfur dioxide removal. A unique project at Carnegie-Mellon University is looking at the concept of integrated environmental control for coal-fired power plants making use of precombustion, combustion, and postcombustion control, including systems for the simultaneous removal of more than one pollutant. The objective of this research is to develop a computer model and assessment for integrated environmental control systems that utilize conventional or advanced systems. The Liquid Phase Methanol Project Development Unit in LaPorte, Texas, was restarted after a successful shakedown run was completed. PETC has recently begun an in-house research project aimed at exploring the basic chemistry of liquefying coal in the presence of water under supercritical conditions. In the Alternative Fuels Technology Program, the Gulf Research and Development Company has completed the preliminary testing phase of its erosion test loop. Their results indicate that when pumping a coal-water slurry fuel through a flow loop, the erosion rate increases as velocity increases, suggesting a well-defined relationship between these two parameters.

    Work this quarter focused on staged liquefaction. The effect of residence time on conversion in single pass experiments was found to be quite different for the subbituminous Belle Ayr Mine and bituminous Illinois No. 6 coals studied. With bituminous coal, conversion to soluble material is quite high and the limit of conversion is approached in only a few minutes. With a subbituminous coal, however, conversion is much lower and the limit of conversion is approached much more slowly. Short contact time (SCT) dissolution of Belle Ayr coal was studied as a possible first stage in a two-stage process. Conversion, hydrocarbon gas yield and hydrogen consumption were increased as residence time or temperature were increased. Conversion was also significantly increased by partial slurry recycle. Pyrite was found to be the most effective slurry catalyst for increasing conversion, followed by ammonium molybdate emulsion and finally nickel-molybdenum on alumina. Illinois No. 6 coal was liquefied in two stages. Conditions in the first stage dissolution were varied to determine the effect on upgradability in the second stage. An SCT (6 minute) coal dissolution stage is preferred over one at 30 minutes because hydrocarbon gas yield was much lower while overall oil yields for the combined dissolution and upgrading stages were nearly the same. Use of a NiMo/Al/sub 2/O/sub 3/ catalyst in a trickle-bed second stage resulted in a higher oil yield and lower product heteroatom content than use of the same catalyst in the slurry phase. The total oil yield was lower with a pyrite slurry catalyst than with a NiMo/Al/sub 2/O/sub 3/ slurry catalyst. With Belle Ayr coal and added pyrite, there was no change in total oil yield, conversion or product quality brought about by adding an 8-minute first stage at 450/sup 0/C (842/sup 0/F) to a 2-hour second stage operated at 420/sup 0/C (788/sup 0/F). 39 figures, 12 tables.

    The overall objective of the project is to develop an integrated two stage fermentation process for conversion of coal-derived synthesis gas to a mixture of alcohols. This is achieved in two steps. In the first step, Butyribacterium methylotrophicum converts carbon monoxide (CO) to butyric and acetic acids. Subsequent fermentation of the acids by Clostridium acetobutylicum leads to the production of butanol and ethanol. The tasks for this quarter were: (1) development/isolation of superior strains for fermentation of syngas, (2) optimization of process conditions for fermentation of syngas, (3) evaluation of bioreactor configuration for improved mass transfer of syngas, (4) development of a membrane-based pervaporation system, (5) optimization of process conditions for reducing carbon and electron loss by H{sub 2}-CO{sub 2} fermentation, and (6) synthesis gas fermentation in single-stage by co-culture. Progress is reported in isolation of CO utilizing anaerobic strains; investigating the product profile for the fermentation of syngas by B. methylotrophicum; and determining the effect of carbon monoxide on growth of C. acetobutylicum.

    Zn-air batteries, which are cost-effective and have high energy density, are promising energy storage devices for renewable energy and power sources for electric transportation. Nevertheless, limited charge and discharge cycles and low round-trip efficiency have long been barriers preventing the large-scale deployment of Zn-air batteries in the marketplace. Technology advancements for each battery component and the whole battery/cell assembly are being pursued, with some key milestones reached during the past 20 years. As an example, commercial Zn-air battery products with long lifetimes and high energy efficiencies are being considered for grid-scale energy storage and for automotive markets. In this review, we present our perspectives on improvements in Zn-air battery technology through the exploration and utilization of different electrolyte systems. Recent studies ranging from aqueous electrolytes to nonaqueous electrolytes, including solid polymer electrolytes and ionic liquids, as well as hybrid electrolyte systems adopted in Zn-air batteries have been evaluated. Understanding the benefits and drawbacks of each electrolyte, as well as the fundamental electrochemistry of Zn and air electrodes in different electrolytes, are the focus of this paper. Further consideration is given to detailed Zn-air battery configurations that have been studied and applied in commercial or nearing commercial products, with the purpose of exposing state-of-the-art technology innovations and providing insights into future advancements.

    Shake flask tests were completed of microbial pyrite and HAP precursor removal from Rosebud subbituminous coal. Significant amounts of Ni, F, Mn, Cd, Co and Be were removed from this coal. Analyses in connection with leach column tests of Pittsburgh coal were completed and confirmed significant removal of Ni, F, Mn, Cd, Co and As from this coal. Although Hg was not removed from Pittsburgh coal by microbial attack, there was a correlation between HCl leaching of Hg from this coal and the extent of depyritization. Since HgS is soluble in HCl, the results suggest HgS is exposed by chemical and microbial dissolution of coal pyrite. Column tests with cleaned Indiana No. 5 coal are in progress and show significant early dissolution of Ni, Mn, Cd, Co and As. A final shake flask test with Kentucky No. 9 coal was begun. Pittsburgh coal with a low content of fines was shipped to the Idaho National Engineering Laboratory (INEL) in preparation for slurry column tests of HAP precursor removal. Project results were presented at the PETC contractor`s conference held in Pittsburgh. A project progress review meeting was also held with the PETC technical project monitor.

    This report describes the status of research being performed under CRADA No. SC10/01771.00 (Lead/Carbon Functionality in VRLA Batteries) between Sandia National Laboratories and East Penn Manufacturing, conducted for the U.S. Department of Energy's Energy Storage Systems Program. The Quarter 2 Milestone was completed on time. The milestone entails an ex situ analysis of the four carbons that have been added to the negative active material of valve-regulated lead-acid (VRLA) batteries for the purposes of this study. The four carbons selected for this study were a graphitic carbon, a carbon black, an activated carbon, and acetylene black. The morphology, crystallinity, and impurity contents of each of the four carbons were analyzed; results were consistent with previous data. Cycling on a subset of the received East Penn cells containing different carbons (and a control) has been initiated. Carbon has been explored as an addition to lead-acid battery electrodes in a number of ways. Perhaps the most notable to date has been the hybrid 'Ultrabattery' developed by CSIRO where an asymmetric carbon-based electrochemical capacitor is combined with a lead-acid battery into a single cell, dramatically improving high-rate partial-state-of-charge (HRPSoC) operation. As illustrated below, the 'Ultrabattery' is a hybrid device constructed using a traditional lead-acid battery positive plate (i.e., PbO{sub 2}) and a negative electrode consisting of a carbon electrode in parallel with a lead-acid negative plate. This device exhibits a dramatically improved cycle life over traditional VRLA batteries, as well as increased charge power and charge acceptance. The 'Ultrabattery' has been produced successfully by both The Furukawa Battery Co. and East Penn Manufacturing. An example illustrating the dramatic improvement in cycle life of the Ultrabattery over a conventional VRLA battery is shown.

    The research, development, and management activities of the programs at Argonne National Laboratory (ANL) and at industrial subcontractors' laboratories on high-temperature batteries during the period October 1977--September 1978 are reported. These batteries are being developed for electric-vehicle propulsion and for stationary-energy-storage applications. The present cells, which operate at 400 to 500/sup 0/C, are of a vertically oriented, prismatic design with one or more inner positive electrodes of FeS or FeS/sub 2/, facing electrodes of lithium--aluminum alloy, and molten LiCl--KCl electrolyte. During this fiscal year, cell and battery development work continued at ANL, Eagle--Picher Industries, Inc., the Energy Systems Group of Rockwell International, and Gould Inc. Related work was also in progress at the Carborundum Co., General Motors Research Laboratories, and various other organizations. A major event was the initiation of a subcontract with Eagle--Picher Industries to develop, design, and fabricate a 40-kWh battery (Mark IA) for testing in an electric van. Conceptual design studies on a 100-MWh stationary-energy-storage module were conducted as a joint effort between ANL and Rockwell International. A significant technical advance was the development of multiplate cells, which are capable of higher performance than bicells. 89 figures, 57 tables.

    This report covers the first 3 months effort of the Ford/DOE Automotive Stirling Engine Development Program, specifically Task I which is Fuel Economy Assessment. At the beginning of this contract effort the projected fuel economy of the 4-215 Stirling engine was 21.16 MPG with a confidence level of 29 percent. Since that date, the fuel economy improvement projection of the 4-215 Stirling engine has been increased to 22.11 MPG, with a confidence level of 29 percent. Collection of fuel economy improvement data is directly related to engine durability. Engine durability has been limited. Since September 19, 1977 a total of 47.7 hours of engine running time has been accumulated using two engine builds. Progress is reported in sub-task studies of burners, preheaters, engine drive, blower system, power control, air-fuel ratio control, cooling system, and cycle control. (LCL)

    Carbon monofluoride (CFx) has a high energy density, exceeding 2000 W h kg(-1), yet its application in primary lithium batteries is limited by its power capability. Multi-walled carbon nanotubes (CNTs) are appealing additives for high-power batteries, due to their outstanding electronic transport properties, high aspect ratio necessitating low volume fraction for percolation, and high tensile strength. This perspective describes the current state of the art in lithium-carbon monofluoride (Li/CFx) batteries and highlights the opportunities for the development of high-power Li/CFx batteries via utilization of carbon nanotubes. In this report, we generated several electrode architectures using CFx/CNT combinations, and demonstrated the effectiveness of CNTs in enhancing the rate capability and energy density of Li/CFx batteries. First, we investigated the resistivity of CFx combined with CNTs and compared the CFx/CNT composites with conventional carbon additives. Second, we built CFx-CNT electrodes without metallic current collectors using CNTs as substrates, and compared their electrochemical performance with conventional CFx electrodes using aluminum foil as a current collector. Furthermore, we fabricated multi-layered CNT-CFx-CNT composite electrodes (sandwich electrodes) and studied the impact of the structure on the performance of the electrode. Our work demonstrates some of the opportunities for utilization of CNTs in CFx electrodes and the resultant implementation of CFx as a battery cathode in next-generation high-power batteries.

    The development of valve regulated lead-acid (VRLA) batteries has, in recent years, been carried forward rapidly through the collaborative efforts of a worldwide consortium of battery manufacturers and related elements of industry; the Advanced Lead-Acid Battery Consortium (ALABC). This group has set aside its competitive instincts in order to achieve acceptable goals in respect of those parameters that are key factors controlling the marketability of electric vehicles (EVs): cost, cycle life, specific energy, specific power and rate of recharge. This paper provides an overview of the principal themes of the ALABC research and development programme.

    Progress is reported in the peat biogasification development program. The objective of the research is to compile the necessary data for the design and operation of a peat anaerobic digestion process development unit. Five areas are addressed: pretreatment information; anaerobic digestion; evaluation of waste streams; process model development and economic analysis; and planning for the process development unit. During the reporting period extensive data was taken for the development of the predictive process model. A number of batch and continuous pretreatment experiments were completed and analyzed. The four samples being analyzed through solvent extration were completed, and the results are presented. Work on High Pressure Liquid Chromatography continued, and the development of the gradient elution solvent system was completed with encouraging results. Pretreated peat has been batch fermented; the continuously oxidized peat has shown conversions of close to 30%. This is significantly higher than the conversions for the batch oxidized peat. Continuous digesters have been in operation for approximately one month. Development of a predictive process model for the three phases of peat biogasification, solubilization, oxidation, and fermentation, continued with very good results. The models for solubilization and oxidation were developed and experimental data are being gathered for the fermentation phase of the process model. (DMC)

  9. Fuel-cycle programs. Quarterly progress report, January-March 1981

    International Nuclear Information System (INIS)

    A program continues for the development of an interim waste form that can be transported from facilities where waste is generated to terminal waste processing. Measurements of rates of leaching from simulated nuclear waste forms ar continuing. The data suggest that leaching from SRL glasses is inhibited by the formation of a Si/Ca/Fe/Al-rich surface layer. Impact tests of solid alternative waste forms (glass and ceramic) are being performed to assess source terms of airborne release (from particle size distributions) and to assess the increases in source terms of leach rates (from increases in surface area). Logging techniques are being developed to measure the relative amount of residual oil in a depleted oil reservoir. A simple technique for the elution of pore fluid (groundwater) from igneous rocks is described, using a special coreholder, as is the elution of brine (in the same apparatus) from a core of Precambrian granite. Testing and development of equipment for the destructive analysis of full-length irradiated fuel rods from the LWBR is in progress

    This report summarizes the progress of the Exploratory Research on Solvent Refined Coal Liquefaction project by The Pittsburgh and Midway Coal Mining Company's Merriam Laboratory for the period April 1, 1979 through June 30, 1979. Experimental work included a number of short residence time runs, but discussion of that work has been delayed until a later report. Experimental work reported focuses on an investigation of the decline in solvent quality experienced by the Wilsonville Pilot Plant during runs in support of the SRC I Demonstration Plant. A four run series was initiated with Wilsonville solvent; both the coal used at Wilsonville (Kentucky 6/11 - Pyro Mine) and Kentucky 9/14 coal from the Colonial Mine were used. The effect of pyrite addition to the Pyro Mine coal was investigated. No solvent quality or coking problems were experienced in the Merriam runs. Significant changes in solvent composition were apparent and equilibrated solvent samples were returned to Wilsonville for solvent quality testing.

  11. Proton resonance spectroscopy. Quarterly technical progress report, December 1992--November 1995

    International Nuclear Information System (INIS)

    Work on chaos in the low-lying levels of nuclei has continued on several fronts. The major effort has been study of the 29Si(p,γ) reaction with the goal of establishing a complete level scheme for 30P and analyzing the eigenvalue fluctuations for evidence of chaos. These measurements are in progress, and the current status is described. A related topic is the search for different signatures of chaos which do not require the extremely high degree of completeness and purity necessary for eigenvalue analyses; those efforts are discussed in Sections 2 and 3. The possibility of studying both parity violation and time-reversal invariance violation with charged particle resonances has been explored by performing calculations using experimentally measured resonance parameters. Large enhancements are indeed available; the results are discussed in Sections 4 and 5. Preparations for an experimental study of parity violation using these techniques are ongoing. An undergraduate project searching for experimental evidence of a parity dependence of level density is discussed in Section 6. A number of improvements to the operation of the TUNL KN accelerator have been implemented in the past three years. These are described in Section 7

    This report summarizes the progress of the Solvent Refined Coal (SRC) Project by the Pittsburg and Midway Coal Mining Co. for the Department of Energy for the period January 1, 1979 to March 31, 1979. Activities included the operation and modification of the Solvent Refined Coal Pilot Plant at Fort Lewis, Washington; the Process Development Unit P-99 at Harmarville, Pennsylvania; and research at Merriam Laboratory in Merriam, Kansas. The Pilot Plant processed Powhatan No. 5 Coal in the SRC-II mode of operation studying the effect of coal particle size and system temperature on coal slurry blending and the effect of carbon monoxide concentration in the reaction feed gas on process yields. January and February were spent completing installation of a fourth High Pressure Separator on Process Development Unit P-99 to better simulate operating conditions for the proposed Demonstration Plant. During March, one run was completed at P-99 feeding Pittsburgh Seam Coal from the Powhatan No. 5 Mine. Merriam investigations included a study of the effect of iron containing additives on SRC-I operation, the addition of carbon monoxide to the feed gas, utilization of a hydrogenated solvent (Cresap process solvent) in the SRC-I mode under both normal and short residence time operating conditions, and development of a simulated distillation technique to determine the entire boiling range distribution of product oils.

    The overall objective of the LSA Silicon Material Task is to establish a chemical process for producing silicon at a rate and price commensurate with the production goals of the LSA project for solar-cell modules. As part of the overall Silicon Material Task, Union Carbide developed the silane-silicon process and advanced the technology to the point where it has a definite potential for providing high-purity polysilicon on a commercial scale at a price of $14/kg by 1986 (1980 dollars). This process for preparing semiconductor-grade silicon in the EPSDU from metallurgical-grade (M-G) silicon is based on a well-integrated arrangement of purification steps that provides a cost-effective process system. The three basic steps entail converting M-G silicon to trichlorosilane, redistributing the trichlorosilane to produce silane, and thermally decomposing the silane to form amorphous silicon powder. The powder is then melted and the molten silicon is cast into polycrystalline silicon for subsequent use in fabricating solar cells. Progress is reported on the following tasks: (1) design, fabricate, install, and operate an Experimental Process System Development Unit (EPSDU) sized for 100 MT/Yr to obtain extensive performance data to establish the data base for the design of commercial facilities; (2) perform supporting research and development to provide an information base usable for the EPSDU and for technological design and economic analysis for potential scale-up of the process; and (3) perform iterative economic analyses of the estimated product cost for the product of semiconductor-grade silicon in a facility capable of producing 1000 MT/Yr.

  17. Nuclear medicine technology progress report for quarter ending December 31, 1980

    International Nuclear Information System (INIS)

    A method was developed for the synthesis of terminal haloalkyl (X-R)-substituted selenium (Se)- and tellurium (Te)-long-chain fatty acids. Several iodinated Se- and Te-fatty acids have now been prepared including the iodinated analog of methyl-9-THDA, methyl-17-iodo-9-telluraheptadecanoic acid [I-(CH2)8-Te-(CH2)7-COOCH3]. A principal goal is the preparation and biological evaluation of the 123I-labeled fatty acids. Osmium-191 was produced for the first time in the High Flux Isotope Reactor (HFIR) and supplied to collaborators for patient studies with the /sup 191m/Ir daughter obtained from the 191Os → /sup 191m/Ir generator system. The /sup 191m/Ir is an excellent isotope for first-pass radionuclide angiographic evaluation of ventricular ejection fraction, intracardiac shunts, and a variety of other clinical applications. The factors affecting 191Os production are being investigated and improvements in the generator are in progress. In a new cooperative program, /sup 117m/Sn has been produced in the HFIR and supplied to investigators to investigate the mechanism of labeling of red blood cells (rbc) with /sup 117m/SnCl2 for performing rbc volume measurements, and gated blood pool imaging studies. Labeling is efficient (70%), and the /sup 117m/Sn is strongly bound to the cells. The attractive emission properties and moderate physical half-life of /sup 117m/Sn suggest that /sup 117m/Sn-labeled rbc ejection fraction measurements could be very useful if high specific activity /sup 117m/Sn can be produced. Five production runs of 11C-labeled amino acids were made in conjunction with the Oak Ridge Associated Universities (ORAU). These agents were evaluated for tumor localization, pancreas imaging, and brain scanning in patients and included 11C-DL-valine, 11C-DL-tryptophan, and 11C-l-aminocyclobutanecarboxylic acid (11C-ACBC)

    Full Text Available Rechargeable non-aqueous Li-air battery technology offers potential advantages over other existing battery systems in terms of specific energy and energy density, which could enable the driving range of an electric vehicle to be comparable to that of gasoline vehicles. Development of efficient cathode catalysts and stable electrolytes for the Li-air battery has been intensively investigated for the past several years, and a number of review articles covering different topics are already available. This review mainly focuses on the research activities on rechargeable non-aqueous Li-air batteries at Argonne National Laboratory, with the emphasis on the gains in understanding of electrolyte decomposition, the structure and magnetic properties of lithium peroxide (Li2O2, development of an air-breathing cathode, and the effect of oxygen crossover on the lithium anode. Insights from this research have led to the improvement of the electrochemical performance of Li-air batteries. Promising paths for future work on rechargeable Li-air batteries are also discussed.

    The computational fluid dynamics (CFD) and computational structural mechanics (CSM) focus areas at Argonne's Transportation Research and Analysis Computing Center (TRACC) initiated a project to support and compliment the experimental programs at the Turner-Fairbank Highway Research Center (TFHRC) with high performance computing based analysis capabilities in August 2010. The project was established with a new interagency agreement between the Department of Energy and the Department of Transportation to provide collaborative research, development, and benchmarking of advanced three-dimensional computational mechanics analysis methods to the aerodynamics and hydraulics laboratories at TFHRC for a period of five years, beginning in October 2010. The analysis methods employ well-benchmarked and supported commercial computational mechanics software. Computational mechanics encompasses the areas of Computational Fluid Dynamics (CFD), Computational Wind Engineering (CWE), Computational Structural Mechanics (CSM), and Computational Multiphysics Mechanics (CMM) applied in Fluid-Structure Interaction (FSI) problems. The major areas of focus of the project are wind and water effects on bridges - superstructure, deck, cables, and substructure (including soil), primarily during storms and flood events - and the risks that these loads pose to structural failure. For flood events at bridges, another major focus of the work is assessment of the risk to bridges caused by scour of stream and riverbed material away from the foundations of a bridge. Other areas of current research include modeling of flow through culverts to improve design allowing for fish passage, modeling of the salt spray transport into bridge girders to address suitability of using weathering steel in bridges, CFD analysis of the operation of the wind tunnel in the TFHRC wind engineering laboratory. This quarterly report documents technical progress on the project tasks for the period of October through

    The Site Operator Program was initially established by the Department of Energy (DOE) to incorporate the electric vehicle activities dictated by the Electric and Hybrid Vehicle Research, Development and Demonstration Act of 1976. In the ensuing years, the Program has evolved in response to new legislation and interests. The Program currently includes twelve sites located in diverse geographic, metrologic, and metropolitan areas across the US. Information is shared reciprocally with a thirteenth site, not under Program contract. The vehicles are operator-owned, except for two Griffon vans. The Mission Statement of the Site Operator Program includes three major activities: advancement of electric vehicle technologies; development of infrastructure elements necessary to support significant electric vehicle use; and increasing the awareness and acceptance of electric vehicles (EVs) by the public. The current participants in the Site Operator Program are shown. The ultimate thrust of program activities varies among sites, reflecting not only the Operator`s business interests but also geographic and climate-related operating conditions. This fourth quarter report (FY-94) includes a summary of activities from the previous three quarters. The report section sequence has been revised to provide a more easily seen program overview, and specific operator activities are now found in Appendix A.

  4. Recent research progress on iron- and manganese-based positive electrode materials for rechargeable sodium batteries

    International Nuclear Information System (INIS)

    Large-scale high-energy batteries with electrode materials made from the Earth-abundant elements are needed to achieve sustainable energy development. On the basis of material abundance, rechargeable sodium batteries with iron- and manganese-based positive electrode materials are the ideal candidates for large-scale batteries. In this review, iron- and manganese-based electrode materials, oxides, phosphates, fluorides, etc, as positive electrodes for rechargeable sodium batteries are reviewed. Iron and manganese compounds with sodium ions provide high structural flexibility. Two layered polymorphs, O3- and P2-type layered structures, show different electrode performance in Na cells related to the different phase transition and sodium migration processes on sodium extraction/insertion. Similar to layered oxides, iron/manganese phosphates and pyrophosphates also provide the different framework structures, which are used as sodium insertion host materials. Electrode performance and reaction mechanisms of the iron- and manganese-based electrode materials in Na cells are described and the similarities and differences with lithium counterparts are also discussed. Together with these results, the possibility of the high-energy battery system with electrode materials made from only Earth-abundant elements is reviewed. (review)

  5. Final Progress Report for Linking Ion Solvation and Lithium Battery Electrolyte Properties

    2014-08-29

    The research objective of this proposal was to provide a detailed analysis of how solvent and anion structure govern the solvation state of Li+ cations in solvent-LiX mixtures and how this, in turn, dictates the electrolyte physicochemical and electrochemical properties which govern (in part) battery performance. Lithium battery electrolytes remain a poorly understood and hardly studied topic relative to the research devoted to battery electrodes. This is due to the fact that it is the electrodes which determine the energy (capacity) of the battery. The electrolyte, however, plays a crucial role in the practical energy density, power, low and/or high temperature performance, lifetime, safety, etc. which is achievable. The development within this project of a "looking glass" into the molecular interactions (i.e., solution structure) in bulk electrolytes through a synergistic experimental approach involving three research thrusts complements work by other researchers to optimize multi-solvent electrolytes and efforts to understand/control the electrode-electrolyte interfaces, thereby enabling the rational design of electrolytes for a wide variety of battery chemistries and applications (electrolytes-on-demand). The three research thrusts pursued include: (1) conduction of an in-depth analysis of the thermal phase behavior of diverse solvent-LiX mixtures, (2) exploration of the ionic association/solvate formation behavior of select LiX salts with a wide variety of solvents, and (3) linking structure to properties-determination of electrolyte physicochemical and electrochemical properties for comparison with the ionic association and phase behavior.

The Quarter 3 Milestone was completed on time. The milestone entails an ex situ analysis of a control as well as three carbon-containing negative plates in the raw, as cast form as well as after formation. The morphology, porosity, and porosity distribution within each plate was evaluated. In addition, baseline electrochemical measurements were performed on each battery to establish their initial performance. These measurements included capacity, internal resistance, and float current. The results obtained for the electrochemical testing were in agreement with previous evaluations performed at East Penn manufacturing. Cycling on a subset of the received East Penn cells containing different carbons (and a control) has been initiated.

    Activities during the second quarter included the second meeting of the Site Operators in Phoenix, AZ in late April. The meeting was held in conjunction with the Solar and Electric 500 Race activities. Delivery of vehicles ordered previously has begun, although two of the operators are experiencing some delays in receiving their vehicles. Public demonstration activities continue, with an apparent increasing level of awareness and interest being displayed by the public. Initial problems with the Site Operator Database have been corrected and revised copies of the program have been supplied to the Program participants. Operating and Maintenance data is being supplied and submitted to INEL on a monthly basis. Interest in the Site Operator Program is being reflected in requests for information from several organizations from across the country, representing a wide diversity of interests. These organizations have been referred to existing Site Operators with the explanation that the program will not be adding new participants, but that most of the existing organizations are willing to work with other groups. The exception to this was the addition of Potomac Electric Power Company (PEPCO) to the program. PEPCO has been awarded a subcontract to operate and maintain the DOE owned G-Van and Escort located in Washington, DC. They will provide data on these vehicles, as well as a Solectria Force which PEPCO has purchased. The Task Force intends to be actively involved in the infrastructure development in a wide range of areas. These include, among others, personnel development, safety, charging, and servicing. Work continues in these areas. York Technical College (YORK) has completed the draft outline for the EV Technician course. This is being circulated to organizations around the country for comments. Kansas State University (KSU) is working with a private sector company to develop a energy dispensing meter for opportunity charging in public areas.

    This report describes the status of research being performed under CRADA No. SC10/01771.00 (Lead/Carbon Functionality in VRLA Batteries) between Sandia National Laboratories and East Penn Manufacturing, conducted for the U.S. Department of Energy's Energy Storage Systems Program. The Quarter 1 Milestone was completed on time. The milestone entails conducting a thorough literature review to establish the current level of understanding of the mechanisms through which carbon additions to the negative active material improve valve-regulated lead-acid (VRLA) batteries. Most studies have entailed phenomenological research observing that the carbon additions prevent/reduce sulfation of the negative electrode; however, no understanding is available to provide insight into why certain carbons are successful while others are not. Impurities were implicated in one recent review of the electrochemical behavior of carbon additions. Four carbon samples have been received from East Penn Manufacturing and impurity contents have been analyzed. Carbon has been explored as an addition to lead-acid battery electrodes in a number of ways. Perhaps the most notable to date has been the hybrid 'Ultrabattery' developed by CSIRO where an asymmetric carbon-based electrochemical capacitor is combined with a lead-acid battery into a single cell, dramatically improving high-rate partial-state-of-charge (HRPSoC) operation. As illustrated below, the 'Ultrabattery' is a hybrid device constructed using a traditional lead-acid battery positive plate (i.e., PbO{sub 2}) and a negative electrode consisting of a carbon electrode in parallel with a lead-acid negative plate. This device exhibits a dramatically improved cycle life over traditional VRLA batteries, as well as increased charge power and charge acceptance. The 'Ultrabattery' has been produced successfully by both The Furukawa Battery Co. and East Penn Manufacturing. An example illustrating the dramatic

    The primary goal of this project is the engineering development of two advanced physical fine coal cleaning processes, column flotation and selective agglomeration, for premium fuel applications. The project scope includes laboratory research and bench-scale testing on six coals to optimize these processes, followed by design, and construction of a 2-t/hr process development unit (PDU). The PDU will then be operated to generate 200 tons of each of three project coals, by each process. During Quarter 11 (April--June, 1995), work continued on the Subtask 3.2 in-plant testing of the Microcel{trademark} flotation column at the Lady Dunn Preparation Plant with the installation and calibration of a refurbished 30-inch diameter column. The evaluation of toxic trace element data for column flotation samples continued, with preliminary analysis indicating that reasonably good mass balances were achieved for most elements, and that significant reductions in the concentration of many elements were observed from raw coal, to flotation feed, to flotation product samples. Significant progress was made on Subtask 6.5 selective agglomeration bench-scale testing. Data from this work indicates that project ash specifications can be met for all coals evaluated, and that the bulk of the bridging liquid (heptane) can be removed from the product for recycle to the process. The detailed design of the 2 t/hr selective agglomeration module progressed this quarter with the completion of several revisions of both the process flow, and the process piping and instrument diagrams. Procurement of coal for PDU operation began with the purchase of 800 tons of Taggart coal. Construction of the 2 t/hr PDU continued through this reporting quarter and is currently approximately 60% complete.

    Research in this project centers upon developing a new approach to the direct liquefaction of coal to produce an all-distillate product slate at a sizable cost reduction over current technology. The approach integrates all aspects of the coal liquefaction process including coal selection, pretreatment, coal swelling with catalyst impregnation, coal liquefaction experimentation, product recovery with characterization, alternate bottoms processing, and a technical assessment including an economic evaluation. The project is being carried out under contract to the United States Department of Energy. On May 28, 1992, the Department of Energy authorized starting the experimental aspects of this projects; therefore, experimentation at Amoco started late in this quarterly report period. Research contracts with Auburn University, Pennsylvania State University, and Foster Wheeler Development Corporation were signed during June, 1992, so their work was just getting underway. Their work will be summarized in future quarterly reports. A set of coal samples were sent to Hazen Research for beneficiation. The samples were received and have been analyzed. The literature search covering coal swelling has been up-dated, and preliminary coal swelling experiments were carried out. Further swelling experimentation is underway. An up-date of the literature on the liquefaction of coal using dispersed catalysts is nearing completion; it will be included in the next quarterly report.

    1993-10-01

    Phase II research involves a scale-up from microgram to gram quantities of sorbent and a switch from the electrobalance reactor to a fixed-bed reactor with capability for feed and product gas analysis. Parameters being studied in Phase II are essentially the same as in Phase I. The reactor response is being studied as a function of calcination and carbonation temperature and pressure, composition of the calcination and carbonation feed gas, and space velocity during the carbonation cycle. Multicycle tests are also being conducted to extend the information on sorbent durability. During the current quarter, reactor modifications to permit easier addition and removal of sorbent to and from the reactor were accomplished. It is now possible to remove sorbent after a run in discrete axial sections which will permit characterization of the sorbent as a function of axial position. Tracer response tests in which the chromatograph response to step function injections of hydrogen to flowing nitrogen under non-reactive conditions were carried out to evaluate the lag time between feeding reactive gases to the reactor and their appearance in the product gas sample. Fourteen additional calcination/carbonation reaction tests were completed this quarter, and the effects of carbonation background gas composition, sorbent particle size, calcination temperature, calcination gas flow rate, and calcination gas composition were studied. In addition, the first multicycle test involving complete calcination/carbonation cycles was carried out.

    During the first quarter of this contract, facilities for the spray pyrolysis deposition of CdTe thin films using a process anolagous to that used to spray deposit device-quality films of CdS were prepared. A Te salt, ..beta..-(CH/sub 3/)/sub 2/TeI/sub 2/, suitable for use in the spray process was synthesized. The facilities were shown to function properly by the successful spraying of good quality CdS thin films. A number of initial spray experiments were conducted utilizing the ..beta..-(CH/sub 3/)/sub 2/TeI/sub 2/ and other inorganic tellurium-bearing compounds which also show great promise in producing low-cost sprayed CdTe solar cells. Initial chemical tests of these films indicated the presence of both Cd and Te, and x-ray diffraction analysis is presently underway to determine the actual concentration of CdTe.

  1. Plasma theory and simulation: Quarterly progress report Nos. 1 and 2, January 1, 1986-June 30, 1986

    International Nuclear Information System (INIS)

    This quarterly report deals with General Plasma Theory and Simulation. Computer simulation of bounded plasma systems, with external circuits, is discussed in considerable detail. Artificial cooling of trapped electrons in bounded simulations was observed and is now attributed to noiseless injection; the cooling does not occur if random injection is used. This report also deals with Plasma-Wall Physics and Simulation. The collector and source sheaths at the boundaries of warm plasma are treated in detail, including ion reflection and secondary electron emission at the collector. The Kelvin-Helmholtz instability is observed in a self-consistent magnetized sheath, producing long-lived vortices which increase the particle transport to the wall dramatically

    Efforts this past quarter emphasized the assembly of a three source deposition system, studies of the chemical composition of the surface of Cu/sub 2/O substrates, continued investigation of current mechanisms in Cu/Cu/sub 2/O Schottky barriers, and fabrication and characterization of Cu/SiO/sub 2//Cu/sub 2/O MIS cells. Time was also devoted to further calculations of expected photocurrent from Cu/sub 2/O solar cells, and thermodynamic considerations concerning the stability of interfaces in possible Cu/sub 2/O cell structures. Key accomplishments include: (1) measurement of optical absorption coefficient for Cu/sub 2/O; (2) completion of MBE system; (3) preliminary identification of two current mechanisms operative in Cu/Cu/sub 2/O cells.

    1979-10-01

    During the second quarter of this program primary emphasis was put into depositing and evaluating both n and p-type CdTe films on a variety of conducting and non-conducting substrates. Improvements in the deposition apparatus permitted preparation of a large number of CdTe films and numerous analytic techniques available at Tufts University were utilized to examine these films. It was found that the introduction of a thin (100 A). In layer between the ITO and the CdTe significantly reduced the previously observed barrier present at the ITO/n-CdTe interface without adversely reducing optical transmission. While the resistivity of the films is still rather high, very recent results show that proper changes in procedure are capable of markedly lowering the resistivity. Preliminary Schottky barrier devices have been made which show promising photovoltaic characteristics.

    The objective Task 1, Synthesis of Propionates, is to develop the technology for the synthesis of low-cost propionates. These propionates are the basic feedstock for the subsequent reaction with formaldehyde to produce the target molecule, methyl methacrylate (MMA). Eastman has explored several possible routes to the propionates and has concluded that the most promising is the synthesis of propionic anhydride from the reaction of propionic acid from and ethylene (and also hydrogen in some cases). The main advantage of the anhydride over the acid is that its subsequent reaction with formaldehyde does not produce water, which can lead to undesired byproducts. Bechtel is carrying out a cost analysis of the Eastman route to the anhydride to determine if it is potentially competitive with commercially practiced routes to the same molecule. The answer is expected next quarter. The objective Task 2, Condensation Catalysis to develop catalysts for the condensation of the propionate (propionic anhydride is our target molecule) with formaldehyde. This reaction produces methacrylic acid (MAA), which would then be reacted with methanol to produce MMA in the slurry reactor. We have synthesized a wide range of catalysts and the results show that there is substantial byproduct formation, including 3-pentanone and some propionic acid. Our results show the highest yields of MAA using an alkalized alumina (1%Na/{sub y}-AI{sub 2}O{sub 3}). Although the condensation of propionic acid with formaldehyde is well studied in the literature, little is reported on the condensation of the anhydride. Although it is likely that the same general types of acid/base catalysts that promote the acid condensation will also promote that of the anhydride, the strength and balance of the acid and base sites is likely to be different. We plan to explore the relationship of the catalyst properties and MMA yields using the Altamira system, due to be delivered this next quarter.

    This report covers the research, development, and management activities of the programs at Argonne National Laboratory (ANL) and at subcontractors' laboratories on high-temperature batteries during the period October 1978 to March 1979. These batteries are being developed for electric-vehicle propulsion and for stationary energy-storage applications. The present cells, which operate at 400 to 500/sup 0/C, are of a vertically oriented, prismatic design with one or more inner positive electrodes of FeS or FeS/sub 2/, facing electrodes of lithium-aluminum alloy, and molten LiCl-KCl electrolyte. During this six-month period, cell and battery development work continued at ANL, Eagle-Picher Industries, Inc., Gould Inc., and the Energy Systems Group of Rockwell International. Fabrication of a 40-kWh battery by Eagle-Picher for testing in an electric van is nearing completion. Cost and design studies for a Mark II electric-vehicle battery, which will have somewhat higher performance and use potentially low-cost materials and fabrication methods, were conducted by all three subcontractors, and contracts are being negotiated for development of Mark II batteries. Conceptual design studies continued at Rockwell International on a 100 MWh stationary energy-storage module. The present plan is to construct a module based on these designs for testing at the BEST (Battery Energy Storage Test) Facility. Work was also in progress at the Carborundum Co., General Motors Research Laboratories, and various other organizations on developing materials and components for cells. 38 figures, 28 tables.

    The overall objective of this 29-month program is to develop and verify the design of a prototype molten carbonate fuel cell stack which meets the requirements of 1990's competitive coal-fired electrical utility central station or industrial cogeneration power plants. During this quarter, effort was continued in all four major task areas: Task 1 - system studies to define the reference power plant design; Task 2 - cell and stack design, development and verification; Task 3 - preparation for fabrication and testing of the full-scale prototype stack; and Task 4 - developing the capability for operation of stacks on coal-derived gas. In the system study activity of Task 1, preliminary module and cell stack design requirements were completed. Fuel processor characterization has been completed by Bechtel National, Inc. Work under Task 2 defined design approaches for full-scale stack busbars and electrical isolation of reactant manifolds and reactant piping. Preliminary design requirements were completed for the anode. Conductive nickel oxide for cathode fabrication has been made by oxidation and lithiation of porous nickel sheet stock. A method of mechanizing the tape casting process for increased production rates was successfully demonstrated under Task 3. In Task 4, theoretical calculations indicated that hydrogen cyanide and ammonia, when present as impurities in the stack fuel gas, will have no harmful effects. Laboratory experiments using higher than anticipated levels of ethylene showed no harmful effects. Components for the mobile test facility are being ordered.

    The objectives of this project are to support the DOE direct coal liquefaction process development program and to improve the useful application of analytical chemistry to direct coal liquefaction process development. Independent analyses by well-established methods will be obtained of samples produced in direct coal liquefaction processes under evaluation by DOE. Additionally, analytical instruments and techniques which are currently underutilized for the purpose of examining coal-derived samples will be evaluated. The data obtained from this study will be used to help guide current process development and to develop an improved data base on coal and coal liquids properties. A sample bank will be established and maintained for use in this project and will be available for use by other researchers. The reactivity of the non-distillable resids toward hydrocracking at liquefaction conditions (i.e., resid reactivity) will be examined. From the literature and data experimentally obtained, a mathematical kinetic model of resid conversion will be constructed. It is anticipated that such a model will provide insights useful for improving process performance and thus the economics of direct coal liquefaction. Accomplishments for this quarter are described.

    1977-01-01

    The first pair of hydrogenation experiments with protium and deuterium has been completed and the products from each test have been solvent-fractionated. The good agreement with respect to yields between the two sets of solvent-fractionation data suggests that the products from these two tests should provide excellent material for developing, evaluating, and establishing the deuterium tracer technique. Products from the hydrogenation experiments have been analyzed by elemental analysis. Gel permeation chromatography has been used to investigate molecular weight distributions. Also, the absolute weight fraction of deuterium in these products have been determined. The water formed during the combustion analyses has been condensed and analyzed by mass spectrometry for /sup 1/H/sub 2/O, /sup 1/H/sup 2/HO, and /sup 2/H/sub 2/O content. The soluble products obtained have been analyzed by proton, deuteron, and carbon-13 nuclear magnetic resonance spectroscopy. Evaluation of all the spectra has been completed. The conditions under which this test pair had been conducted led to an extensive distribution of the deuterium label with respect to structural positions in the products. A third hydrogenation experiment with protium was performed during this quarter at a lower temperature and for a shorter reaction time in an attempt to enhance the specificity of the deuterium uptake.

    The Office of Space and Defense Power Systems (OSDPS) of the Department of Energy (DOE) provides Radioisotope Power Systems (RPS) for applications where conventional power systems are not feasible. For example, radioisotope thermoelectric generators were supplied by the DOE to the National Aeronautics and Space Administration for deep space missions including the Cassini Mission launched in October of 1997 to study the planet Saturn. The Oak Ridge National Laboratory (ORNL) has been involved in developing materials and technology and producing components for the DOE for more than three decades. For the Cassini Mission, for example, ORNL was involved in the production of carbon-bonded carbon fiber (CBCF) insulator sets, iridium alloy blanks and foil, and clad vent sets (CVSs) and weld shields (WSs). This quarterly report has been divided into three sections to reflect program guidance from OSDPS for fiscal year (FY) 2000. The first section deals primarily with maintenance of the capability to produce flight quality carbon-bonded carbon fiber (CBCF) insulator sets, iridium alloy blanks and foil, clad vent sets (CVSs), and weld shields (WSs). In all three cases, production maintenance is assured by the manufacture of limited quantities of flight quality (FQ) components. The second section deals with several technology activities to improve the manufacturing processes, characterize materials, or to develop technologies for two new RPS. The last section is dedicated to studies of the potential for the production of 238Pu at ORNL.

    Further progress has been made in formulation of the thermodynamically consistent, rate dependent model for turbulent two-phase flows. The thermodynamically admissible constitutive equations were derived, and the case of a simple shear flow was studied. The kinetic model for rapid flows of granular materials, which includes frictional losses, was used for studying gravity flow down an inclined chute. Some typical velocity profiles were obtained and the results were compared with the data of Savage. The effect of inter-particle friction was also studied. Progress has been made in developing a computational model for rapid granular and two-phase flows in complex geometries. A discrete element numerical scheme was used for granular flow analysis. A predictor-corrector numerical procedure was developed for analyzing two-phase flows. Progress has been made in the construction of the experimental simple shear flow device. The design of the device was improved and its main body was assembled.

    Two long gasification tests were accomplished (66 and 72 hours of slagging operation) this quarter, and the balance of the wastewater needed for the second cooling tower (CT) test (approx. 11,000 gallons) was generated. Eleven thousand gallons of slagging fixed-bed gasifier (SFBG) wastewater were solvent extracted and ammonia stripped (AS) to nominal levels of 160 mg/1 phenol and 600 mg/1 NH/sub 3/. This wastewater is being further treated by activated sludge (AS) and granular activated carbon (GAC) processing to prepare a high quality makeup for the second CT test. Phenol mass balances indicated that > 90 pct of the phenol was stripped from the tower, indicating that previous assumptions of high levels of biodegradation were erroneous. Over 80 pct of the ammonia and about 25 pct of the methanol were also stripped. Data collected during steady state operation of the bench-scale rotating biological contractor indicate complete removal of phenolics and alcohols, and 94 pct removal of BOD. Nitrification also occurred in this unit, with over 30 pct removal of ammonia. Problems due to individual bacteria, present in the biotreated wastewater, passing through the multi-media filter and thus decreasing the carbon adsorption efficiency of the GAC system, have resulted in lower treatment rates than originally anticipated. As a result, to achieve the desired treatment, the contact time of the wastewater with the carbon in the granular activated carbon system has been increased. Since this has decreased the treatment rate, a larger carbon adsorption system has been designed and is presently being constructed.

    Activities in survey programs are reported. A site for taking a core of New Albany Shale has been selected in Clark County. Work continued on drafting final copies of the interlocking stratigraphic cross sections in the Illinois and Michigan Basins. Minor corrections and additions are being made as drafting continues. Illinois Basin: Work continues on preparation of the preliminary isopach map of the Sweetland Creek Member in the Illinois Basin. Samples from key wells were examined to establish the relationship of the Sweetland Creek Member with the overlying Grassy Creek Member and underlying Blocher Member as accurately as possible. Preparation of an isopach map of the Blocher also continued during the quarter. Correlations have been established for the unit from its type section in Scott County to sections in the Illinois Basin and along the outcrop. Sample studies are being made at intervals along each of the stratigraphic cross section lines.

    This report summarizes the technical progress achieved during the first quarter of the ERIP project entitled, ``Laser Ultrasonic Furnace Tube Coke Monitor.`` The focus of work during this reporting period was the testing of a novel device for introducing a broad bandwidth ultrasonic pulse at the surface of a simulated furnace tube. The device employs a sacrificial stand-off composed of a fusible alloy that conforms to hot furnace tube surface upon contact. Conventional high-temperature couplants have a maximum operating temperature of about 550{degrees}C, which limits their use for contact against ethylene cracker furnace tube surfaces that typically operate at about 1000{degrees}C. In the absence of a couplant, insufficient ultrasonic energy can be transmitted from the transducer to the tube surface. By using a fusible alloy, the device efficiently couples the transducer to the hot furnace tube surface, even for rough and convex tube surfaces operating at temperatures of 1800{degrees}F and above. Initial tests confirmed the ability to resolve pulse echoes in a simulated furnace tube using a 5 MHz piezoelectric transducer with a fusible stand-off.

    This program consists of the engineering design, fabrication, assembly, operation, economic analysis, and process support R and D for an Experimental Process System Development Unit (EPSDU). EPSDU equipment specification, vendor development, and evaluation of quotations represent a significant effort which will permit the start of ordering EPSDU equipment during the next quarter. Initial mini-burner test results are encouraging. It appears that a fairly simple and cost-effective waste treatment system may be possible. Engineering design packages such as the P and I, electrical one-line, and layout are also progressing well. The free-space reactor PDU was assembled and is undergoing checkout. The modified seal and shaft of the reactor scraper ran with limited success. A computer modeling of the PDU has been prepared using a two-dimensional axisymmetric model with recirculation. Some test runs have been made. Work on determination of the critical silane decomposition in a fixed bed has been completed. The data generated follow the extension of the Murthy's data. This data, along with the deposition rate data to be acquired, will be used in the fluid-bed reactor design. Present test data show that capacitive heating of the fluid bed and particle separation in a boot are very promising.

    The main goal of this program is to demonstrate the utility of coal extracts from the West Virginia University (WVU) extraction process as suitable base raw materials for the carbon products encompassed by the Carbon Products Consortium (CPC) team. This quarterly report covers activities during the period from April 1, 1996 through June 30, 1996. The first year of the project ended in February, 1996; however, the WVU research effort has continued on a no-cost extension of the original contract. Samples have been supplied to CPC participants so they could conduct their portions of the project as contracted through ORNL. Progress reports are presented for the following tasks: project planning and administration; consortium administration and reporting; coal extraction; technical/economic evaluation of WVU extraction process; and technology transfer. Previous work has shown that the WVU coal extraction process coupled with hydrotreatment, does have the potential for producing suitable base raw materials for carbon products. Current effort, therefore, involved the screening and evaluation of extracts produced by the WVU Group and recommending appropriate materials for scaleup for subsequent evaluation by Consortium Team members. As part of this program, the activation of the coal extraction residues was investigated for the purpose of producing a useful active carbon. A further task, which was started towards the end of the program, was to fabricate a small graphite artifact using Coke derived from coal extract as the filler and the coal extract itself as a binder. The results of these studies are summarized in this report.

    The scope of the contract covers the development and evaluation of forming solar cell collector grid contacts by the MIDFILM process. This is a proprietary process developed by the Ferro Corporation which is a subcontractor for the program. The MIDFILM process attains line resolution characteristics of photoresist methods with processing related to screen printing. The surface to be processed is first coated with a thin layer of photoresist material. Upon exposure to ultraviolet light through a suitable mask, the resist in the non-pattern area cross-links and becomes hard. The unexposed pattern areas remain tacky. The conductor material is applied in the form of a dry mixture of metal and frit particles which adhere to the tacky pattern area. The assemblage is then fired to ash the photopolymer and sinter the fritted conductor powder. Effort was concentrated during this period on the establishment, optimization and identification of problem areas of the MIDFILM process. Progress is reported. (WHK)

  2. Reversed field pinch dynamics and transport studies. Quarterly progress report, 20 July 1983-20 October 1983

    International Nuclear Information System (INIS)

    Progress in RFP dynamics and transport studies is described. The compressible, three-dimensional code SPECTR3 has been modified to include toroidal effects, and classical resistivity and thermal conductivity. Anomalous transport arising from stochastic magnetic fields has been included in the model. These transport effects are treated implicitly. A three-dimensional, incompressible MHD code has been developed. It is computationally more efficient than the existing code, and will be used extensively if compessibility is determined to be unimportant. Post-processor codes to analyze data generated by the nonlinear code have been developed. Three-dimensional computer runs at low THETA (= B/sub theta/(a)/) have found the development of a substantial stochastic core, with good flux surfaces being retained in the outer part of the discharge. Runs at high THETA have shown complete stochasticity, with reappearance of outer flux surfaces as the modes saturate and relax. Anomalous maintenance of positive toroidal flux arising from a poloidal electric field at the field reversal surface induced by MHD fluctuations (dynamo) has been observed. We are collaborating with the ETA-BETA-II experimental group at Padua, Italy, in an attempt to interpret measured internal fluctuations and profiles in terms of resistive MHD. The emphasis of this work is on the effect of MHD fluctuations plasma transport. Analytic studies of the RFP dynamo have begun. We are attempting to find steady state solutions with flow to the resistive MHD equations. A reduced model to simulate phenomena that occur on the relaxation time scale, such as F-THETA current drive, has been formulated

    锂硫电池由于其高理论能量密度(2600W·h/kg)而受到了广泛的关注,是极具应用前景的电池体系。硫基正极材料作为锂硫电池的重要组成部分,是提高电池性能的关键。然而锂硫电池还存在一些问题,如硫的利用率低及正极结构的稳定性差等。本文综述了近几年锂硫电池硫正极复合材料的研究现状,分别从硫/碳复合、硫/导电聚合物复合、硫/氧化物复合3个方面进行介绍,指出了未来锂硫电池正极材料要注意结合硫/导电聚合物及硫/氧化物的优势并注重材料结构的设计,向核壳或类核壳结构方向发展的趋势,同时还要提高载硫量,提高循环稳定性,以获得高性能的锂硫电池。%As a promising battery system,lithium-sulfur battery with high theoretical energy density (2600W·h/kg) has attracted great attention. As one of the essential ingredients for lithium-sulfur batteries,sulfur cathode material is the key to improve the performance of batteries. However,there are some serious and unavoidable problems for lithium-sulfur battery,such as low utilization efficiency of sulfur in cathode and poor stability of electrode structure. In this review,the recent progress of sulfur composites as cathode materials for lithium-sulfur batteries is introduced. Cathode materials are divided into three kinds of composites,such as sulfur/carbon,sulfur/polymer and sulfur/oxide composite materials,which are discussed respectively. It is pointed out that the coming development of cathode materials for lithium-sulfur batteries should be focused on the combination of advantages of sulfur/polymer and sulfur/oxide composite materials,and the design of material structure,such as core-shell or core-shell-like structure for cathode materials. At the same time,high sulfur loading and high cycle stability will be good for the performance improvement of lithium-sulfur batteries.

    Background/Aims Measuring and predicting Alzheimer's disease (AD) progression is important in order to adjust treatment and allocate care resources. We aimed to identify a combination of subtests from the Consortium to Establish a Registry for Alzheimer's Disease Neuropsychological Battery (CERAD-NB) that best correlated with AD progression in follow-up as well as to predict AD progression. Method A total of 236 participants with very mild [Clinical Dementia Rating (CDR) = 0.5] or mild AD (CDR = 1.0) at baseline were followed up for 3 years. The CERAD-NB and Mini-Mental State Examination (MMSE) were used to assess cognition, and the CDR scale sum of boxes (CDR-sb) was employed to evaluate AD progression. Generalized estimating equations were used to develop models to predict and follow up disease progression. Results Performance declined on all CERAD-NB subtests. The ability of the separate subtests to distinguish between groups (baseline CDR = 0.5 or 1.0) diminished during follow-up. The best combination of subtests that explained 62% of CDR-sb variance in follow-up included verbal fluency, constructional praxis, the clock drawing test, and the MMSE. Baseline values of the same combination predicted 37% of the CDR-sb change. Conclusion A short version of the CERAD-NB subtests provides a promising and time-efficient alternative for measuring cognitive deterioration during AD follow-up. Although the initial signs of AD include memory difficulties, it may be useful to assess non-memory tasks in follow-up. PMID:25685140

    1993-12-31

    This quarterly report discusses the technical progress of an Innovative Clean Coal Technology (ICCT) demonstration being conducted at Georgia Power Company`s Plant Hammond Unit 4 located near Rome, Georgia. The primary goal of this project is the characterization of the low NO{sub x} combustion equipment through the collection and analysis of long-term emissions data. A target of achieving fifty percent NO{sub x} reduction using combustion modifications has been established for the project. The project provides a stepwise retrofit of an advanced overfire air (AOFA) system followed by low NO{sub x} burners (LNB). During each test phase of the project, diagnostic, performance, long-term, and verification testing will be performed. These tests are used to quantify the NO{sub x} reductions of each technology and evaluate the effects of those reductions on other combustion parameters such as particulate characteristics and boiler efficiency. During this quarter, long-term testing of the LNB + AOFA configuration continued and no parametric testing was performed. Further full-load optimization of the LNB + AOFA system began on March 30, 1993. Following completion of this optimization, comprehensive testing in this configuration will be performed including diagnostic, performance, verification, long-term, and chemical emissions testing. These tests are scheduled to start in May 1993 and continue through August 1993. Preliminary engineering and procurement are progressing on the Advanced Low NOx Digital Controls scope addition to the wall-fired project. The primary activities during this quarter include (1) refinement of the input/output lists, (2) procurement of the distributed digital control system, (3) configuration training, and (4) revision of schedule to accommodate project approval cycle and change in unit outage dates.

Lithium air battery has the compelling advantage of theoretical specific energy, i.e. 3622 Wh·kg^-1 (assuming Li2O2 is the product), which is attributed to the use of a lithium metal anode and the ready availability of the cathode oxidant, i.e. oxygen, from the surrounding air. Other advantages include stable potentials, high safety, low cost, friendly to environment. However, before Lithium air batteries can be commercialized, the following challenges still need to be overcome: optimization of the cathode materials structure and the electrolyte composition, enhancement of the actual discharge special capacity, and improvement of the cycle performance and elucidating the reaction mechanism that occurs during charge and discharge. In this paper, we presented the current research progress and the limiting factors that affect performance of the batteries, such as microcomposition and microstructure of the cathode materials, constitution of the electrolytes, oxygen selective membranes, the structure design for the lithium air batteries, charge and discharge mechanism; compared

    Membrane testing in the full-cell environment has been successful in H{sub 2}S removal applications, but largely ineffective for obtaining high current efficiencies due to hydrogen leakage through the membrane. A preprocessed zirconia membrane successful in past experiments was utilized in continued efforts to truncate hydrogen cross-over. An alternative material forming a stabilized conductive cathode under 100 ppmv H{sub 2}S conditions is possible with Co. Development of a Co cathode identical in porosity and pore size to aforementioned nickel cathodes was successfully fabricated and utilized experimentally this quarter.

    During this quarter we have tested our scheme to determine the final products and energy released in the charge transfer of H2+ and H3+ in Cs. These reactions occur at low energy in the volume of the LBL (Leung-Ehlers) surface conversion H- source and can yield suprathermal H atoms as well as vibrationally excited H2, both of which can affect the H- production. The scheme utilizes the fact that H atoms, produced by autodissociation of the excited molecular products of charge transfer in the Cs vapor, have a finite (small) probability of capturing a second electron to form H- before leaving the oven

    This quarterly report discusses the technical progress of an Innovative Clean Coal Technology (ICCT) demonstration of advanced wall-fired combustion techniques for the reduction of nitrogen oxide (NOx) emissions from coal-fired boilers. The project is being conducted at Georgia Power Company`s Plant Hammond Unit 4 located near Rome, Georgia. The primary goal of this project is the characterization of the low NOx combustion equipment through the collection and analysis of long-term emissions data. A target of achieving fifty percent NOx reduction using combustion modifications has been established for the project. The project provides a stepwise retrofit of an advanced overfire air (AOFA) system followed by low NOx burners (LNB). During each test phase of the project, diagnostic, performance, long-term, and verification testing will be performed. These tests are used to quantify the NOx reductions of each technology and evaluate the effects of those reductions on other combustion parameters. Results are described.

    For the past quarter, we have placed our effort in implementing the first version of the ModelBased Iterative Reconstruction (MBIR) algorithm, assembling and testing the electronics, designing transducers mounts, and defining our laboratory test samples. We have successfully developed the first implementation of MBIR for ultrasound imaging. The current algorithm was tested with synthetic data and we are currently making new modifications for the reconstruction of real ultrasound data. Beside assembling and testing the electronics, we developed a LabView graphic user interface (GUI) to fully control the ultrasonic phased array, adjust the time-delays of the transducers, and store the measured reflections. As part of preparing for a laboratory-scale demonstration, the design and fabrication of the laboratory samples has begun. Three cement blocks with embedded objects will be fabricated, characterized, and used to demonstrate the capabilities of the system. During the next quarter, we will continue to improve the current MBIR forward model and integrate the reconstruction code with the LabView GUI. In addition, we will define focal laws for the ultrasonic phased array and perform the laboratory demonstration. We expect to perform laboratory demonstration by the end of October 2015.

    The use of mobile devices is often limited by the capacity of the employed batteries. The battery lifetime determines how long one can use a device. Battery modeling can help to predict, and possibly extend this lifetime. Many different battery models have been developed over the years. However, with these models one can only compute lifetimes for specific discharge profiles, and not for workloads in general. In this paper, we give an overview of the different battery models that are availabl...

    The objective of this program is to examine slags formed as a result of firing coals with varying concentration levels, size distribution, and orientation of pyrite with regard to mineral matter in the coal in a laboratory furnace. The program tasks are: (1) selection of eight candidate coals; (2) chemical characterization of the coal samples and identification of the pyrite size, distribution, and orientation with respect to other mineral matter and concentration levels; (3) testing of the candidate coals in a laboratory furnace; (4) chemical and physical characterization of the slag and fly ash samples created by the impurities in the coal sample; (5) influence of coal beneficiation on furnace slagging; and (6) analysis of data and identification of parameters influencing the contribution of pyrite to slagging problems. Washing of the Upper Freeport coal from Indiana County, Pennsylvania, was completed by the last quarter of 1983. The washed product was characterized for mineral content, and a combustion test was performed. Kentucky No. 9 from Henderson County, Kentucky, selected as the sixth coal to be investigated, was characterized using size and gravity fractionation techniques and was combusted in the laboratory furnace to evaluate its slagging and fouling potential. The remaining two coals to be characterized and combusted were identified as Illinois No. 5 and Lower Kittanning from Clarion County, Pennsylvania. 80 figures, 27 tables.

  17. Progress toward the development of a ground-water velocity model for the radioactive waste management facility, Savannah River Plant, South Carolina: Quarterly report

    International Nuclear Information System (INIS)

    This report presents the status and results of work performed to develop a numerical groundwater velocity model for the radioactive waste management facility at the Savannah River Plant (SRP). Work dealt with developing a hydrologic budget for the McQueen Branch drainage basin. Two hydrologic budgets were developed, covering two periods of time. The first period was from November 1, 1982 to May 19, 1984; the second period was from March 1, 1983 to March 31, 1984. Total precipitation for this period was 52.48 inches, all as rainfall. Water levels measured in wells in the basin quarterly, monthly, and continuously showed basically the same response over the period of the study. Maximum fluctuation of water levels of wells in the basin was five to seven feet during the study. Stream discharge measurements in McQueen Branch showed base flow varying between 1.5 and 5.7 cfs. Lowest base flow occurred during the summer, when evapotranspiration was greatest. Some impact of daily ground-water evapotranspiration from the Branch floodplain was seen in continuous stream records. These daily effects peaked in magnitude during the summer, disappeared during winter, and gradually returned during spring. Underflow past the Branch gauging station out of the basin was determined to be negligible. Leakage downward through the Green Clay is difficult to determine but is believed to be small, based on the overall results of the budget study

    1980-03-01

    The overall objective of this 29-month program is to develop and verify the design of a prototype molten carbonate fuel cell stack which meets the requirements of 1990's competitive coal-fired electrical utility central station or industrial cogeneration power plants. During the first quarter, effort was initiated in all four major task areas: Task 1 - system studies to define the reference power plant design; Task 2 - cell and stack design, development and verification; Task 3 - preparation for fabrication and testing of the full-scale prototype stack; and Task-4 developing the capability for operation of stacks on coal-derived gas. In the system study task, a study baseline fuel cell system and module configuration were established. Studies to determine user requirements and to characterize the fuel cell power block and coal gasifier subsystems were initiated. Cell stack design was initiated with completion of preliminary design requirements for the cell cathodes. Laboratory tests were also initiated to identify alternative materials for separator plates, reactant manifold seals, and electrolyte tile fillers. A mechanical tape casting technique for producing 18 x 24 inch sheets of electrolyte matrix tape was successfully demonstrated in Task 3. In Task 4, theoretical and experimental studies were initiated to define the effects of known sulfur contaminants on cell performance. A literature survey was initiated to identify other possible contaminants. Planning and design efforts for construction of a mobile cell test unit were initiated. The mobile unit will be used to verify the molten carbonate cell's ability to operate on gasified coal by tests at a gasifier site.

    The aim of this contract is to elucidate the mechanisms underlying adsorption and surface precipitation of flooding surfactants on reservoir minerals. The results of this study should help in controlling surfactant loss in chemical flooding and also in developing optimum structures and conditions for efficient chemical flooding processes. Adsorption of single surfactants on silica and alumina as well as the solution behavior of surfactant mixtures was studied during this quarter. The adsorption of surfactants at the solid-liquid interface was correlated with changes in interfacial behavior such as wettability and zeta potential. Surface tension was used to study interactions between surfactant mixtures in solution. Mixed micellization of sodium dodecyl sulfate and dodecyl phenoxy polyethoxylated alcohol was found to be non-ideal. Regular solution theory adequately describes the interactions. The adsorption isotherm of a cationic surfactant, tetradecyl trimethyl ammonium chloride (TTAC), on alumina was determined at two values of pH. Changes in the settling rate of alumina suspensions after TTAC adsorption were also followed to describe the evolution of the adsorbed layer. At high surface coverage it was observed that the alumina surface became hydrophilic suggesting the formation of a TTAC bilayer at the surface. Wettability of silica after adsorption of nonyl phenyl polyethoxylated alcohols (with number of polyethylene oxide groups varying from 10-40) was measured using flotation to determine the orientation of the adsorbed layer. Effect of number of ethylene oxide groups was also determined. The amount of silica floated after the nonionic surfactant adsorption was same irrespective of the ethylene oxide chain length.

    Two Priority One activities have received major attention during this reporting period. Application credits for HVDC systems imbedded in ac links are expected to evolve out of a system study wherein dc is introduced into a system where the breakeven criterion is not satisfied. Alternative benefits of the dc link will be quantified in an attempt to develop an expanded economic basis for HVDC systems. HVDC circuit breaker development is being examined, as there appears to be a relationship between the acceptance of multiterminal dc systems and the availability of a dc breaker. At the present time there is a large technical gap between laboratory status and field availability. Further investigation of dc interruption techniques is recommended, together with the establishment of operating criteria and design specifications. A variety of other HVDC activities was undertaken, including proposal review, contract progress report assessment, inverter commutation with series capacitor assistance, and conference planning.

    The Mulled Coal process was developed as a means of overcoming the adverse handling characteristics of wet fine coal without thermal drying. The process involves the addition of a low cost, harmless reagent to wet fine coal using off-the-shelf mixing equipment. Based on laboratory- and bench-scale testing, Mulled Coal can be stored, shipped, and burned without causing any of the plugging, pasting, carryback and freezing problems normally associated with wet coal. The objectives of this project are to demonstrate that: the Mulled Coal process, which has been proven to work on a wide range of wet fine coals at bench scale, will work equally well on a continuous basis, producing consistent quality at a convincing rate of production in a commercial coal preparation plant; the wet product from a fine coal cleaning circuit can be converted to a solid fuel form for ease of handling and cost savings in storage and rail car transportation; and a wet fine coal product thus converted to a solid fuel form, can be stored, shipped, and burned with conventional fuel handling, transportation, and combustion systems.

    2011-04-19

    There is an ever-growing demand for rechargeable batteries with reversible and efficient electrochemical energy storage and conversion. Rechargeable batteries cover applications in many fields, which include portable electronic consumer devices, electric vehicles, and large-scale electricity storage in smart or intelligent grids. The performance of rechargeable batteries depends essentially on the thermodynamics and kinetics of the electrochemical reactions involved in the components (i.e., the anode, cathode, electrolyte, and separator) of the cells. During the past decade, extensive efforts have been dedicated to developing advanced batteries with large capacity, high energy and power density, high safety, long cycle life, fast response, and low cost. Here, recent progress in functional materials applied in the currently prevailing rechargeable lithium-ion, nickel-metal hydride, lead acid, vanadium redox flow, and sodium-sulfur batteries is reviewed. The focus is on research activities toward the ionic, atomic, or molecular diffusion and transport; electron transfer; surface/interface structure optimization; the regulation of the electrochemical reactions; and the key materials and devices for rechargeable batteries.

  12. Batteries: Overview of Battery Cathodes

    Energy Technology Data Exchange (ETDEWEB)

    Doeff, Marca M

    2010-07-12

    The very high theoretical capacity of lithium (3829 mAh/g) provided a compelling rationale from the 1970's onward for development of rechargeable batteries employing the elemental metal as an anode. The realization that some transition metal compounds undergo reductive lithium intercalation reactions reversibly allowed use of these materials as cathodes in these devices, most notably, TiS{sub 2}. Another intercalation compound, LiCoO{sub 2}, was described shortly thereafter but, because it was produced in the discharged state, was not considered to be of interest by battery companies at the time. Due to difficulties with the rechargeability of lithium and related safety concerns, however, alternative anodes were sought. The graphite intercalation compound (GIC) LiC{sub 6} was considered an attractive candidate but the high reactivity with commonly used electrolytic solutions containing organic solvents was recognized as a significant impediment to its use. The development of electrolytes that allowed the formation of a solid electrolyte interface (SEI) on surfaces of the carbon particles was a breakthrough that enabled commercialization of Li-ion batteries. In 1990, Sony announced the first commercial batteries based on a dual Li ion intercalation system. These devices are assembled in the discharged state, so that it is convenient to employ a prelithiated cathode such as LiCoO{sub 2} with the commonly used graphite anode. After charging, the batteries are ready to power devices. The practical realization of high energy density Li-ion batteries revolutionized the portable electronics industry, as evidenced by the widespread market penetration of mobile phones, laptop computers, digital music players, and other lightweight devices since the early 1990s. In 2009, worldwide sales of Li-ion batteries for these applications alone were US$ 7 billion. Furthermore, their performance characteristics (Figure 1) make them attractive for traction applications such as

    1993-12-13

    The purpose of this work is to identify and characterize candidate conservative organic tracers for use as hydrologic tracers for experiments to be conducted at the Yucca Mountain C-well complex. During this quarter the main effort was directed towards rewriting the quality assurance program in preparation for a review and audit by the USGS. However, due to budget constraints the review and audit were not carried out. The tracer QA plan and standard operating procedures (SOPs) were revised and copies are included in the report. Instrumental problems were encountered and corrected with the addition of new integration and sample control software. In the sampling, there was an unexplained peak in the chromatograms of the tracers being tested in the light tuff. This was not correctable and these experiments will be repeated in the next quarter.

    LiFeBATT has concentrated its recent testing and evaluation on the safety of its batteries. There appears to be a good margin of safety with respect to overheating of the cells and the cases being utilized for the batteries are specifically designed to dissipate any heat built up during charging. This aspect of LiFeBATT’s products will be even more fully investigated, and assuming ongoing positive results, it will become a major component of marketing efforts for the batteries. LiFeBATT has continued to receive prismatic 20 Amp hour cells from Taiwan. Further testing continues to indicate significant advantages over the previously available 15 Ah cells. Battery packs are being assembled with battery management systems in the Danville facility. Comprehensive tests are underway at Sandia National Laboratory to provide further documentation of the advantages of these 20 Ah cells. The company is pursuing its work with Hybrid Vehicles of Danville to critically evaluate the 20 Ah cells in a hybrid, armored vehicle being developed for military and security applications. Results have been even more encouraging than they were initially. LiFeBATT is expanding its work with several OEM customers to build a worldwide distribution network. These customers include a major automotive consulting group in the U.K., an Australian maker of luxury off-road campers, and a number of makers of E-bikes and scooters. LiFeBATT continues to explore the possibility of working with nations that are woefully short of infrastructure. Negotiations are underway with Siemens to jointly develop a system for using photovoltaic generation and battery storage to supply electricity to communities that are not currently served adequately. The IDA has continued to monitor the progress of LiFeBATT’s work to ensure that all funds are being expended wisely and that matching funds will be generated as promised. The company has also remained current on all obligations for repayment of an IDA loan and lease

    Karden, Eckhard; Shinn, Paul; Bostock, Paul; Cunningham, James; Schoultz, Evan; Kok, Daniel

    Introduction of new fuel economy, performance, safety, and comfort features in future automobiles will bring up many new, power-hungry electrical systems. As a consequence, demands on automotive batteries will grow substantially, e.g. regarding reliability, energy throughput (shallow-cycle life), charge acceptance, and high-rate partial state-of-charge (HRPSOC) operation. As higher voltage levels are mostly not an economically feasible alternative for the short term, the existing 14 V electrical system will have to fulfil these new demands, utilizing advanced 12 V energy storage devices. The well-established lead-acid battery technology is expected to keep playing a key role in this application. Compared to traditional starting-lighting-ignition (SLI) batteries, significant technological progress has been achieved or can be expected, which improve both performance and service life. System integration of the storage device into the vehicle will become increasingly important. Battery monitoring systems (BMS) are expected to become a commodity, penetrating the automotive volume market from both highly equipped premium cars and dedicated fuel-economy vehicles (e.g. stop/start). Battery monitoring systems will allow for more aggressive battery operating strategies, at the same time improving the reliability of the power supply system. Where a single lead-acid battery cannot fulfil the increasing demands, dual-storage systems may form a cost-efficient extension. They consist either of two lead-acid batteries or of a lead-acid battery plus another storage device.

  15. EDF - Quarterly Financial Information

    International Nuclear Information System (INIS)

    EDF's sales in the first quarter of 2014 were euro 21.2 billion, down 3.9% from the first quarter of 2013. At constant scope and exchange rates, sales were down 4.2% due to mild weather conditions, which impacted sales of electricity in France, gas sales abroad and trading activities in Europe. UK sales were nonetheless sustained by B2B sales due to higher realised wholesale market prices. In Italy, sales growth was driven by an increase in electricity volumes sold. The first quarter of 2014 also saw the strengthening of the Group's financial structure with the second phase of its multi-annual hybrid funding programme (nearly euro 4 billion equivalent) as well as the issue of two 100-year bonds in dollars and sterling aimed at significantly lengthening average debt maturity. 2014 outlook and 2014-2018 vision: - EDF Group has confirmed its financial objectives for 2014; - Group EBITDA excluding Edison: organic growth of at least 3%; - Edison EBITDA: recurring EBITDA target of euro 1 billion and at least euro 600 million in 2014 before effects of gas contract re-negotiations; - Net financial debt / EBITDA: between 2x and 2.5x; - Pay-out ratio of net income excluding non-recurring items post-hybrid: 55% to 65%. The Group has reaffirmed its goal of achieving positive cash flow after dividends, excluding Linky, in 2018

    Methods of using specific operational charge and discharge parameters to extend the life of alkaline batteries are disclosed. The methods can be used with any commercial primary or secondary alkaline battery, as well as with newer alkaline battery designs, including batteries with flowing electrolyte. The methods include cycling batteries within a narrow operating voltage window, with minimum and maximum cut-off voltages that are set based on battery characteristics and environmental conditions. The narrow voltage window decreases available capacity but allows the batteries to be cycled for hundreds or thousands of times.

    Rechargeable Li–CO2 batteries provide a promising new approach for carbon capture and energy storage technology. However, their practical application is limited by many challenges despite much progress in this technology. Recent development in Li–CO2 batteries is presented. The reaction mechanism with an air cathode, operating temperatures used, electrochemical performance under different CO2 concentrations, stability of the battery in different electrolytes, and utilization of different cathode materials were emphasized. At last, challenges and perspectives were also presented. This review provides a deep understanding of Li–CO2 batteries and offers important guidelines for developing reversible and high efficiency Li–CO2 batteries.%对化石能源依赖所造成的能源安全和环境污染等问题限制了人类社会的可持续发展。 Li-CO2电池能量密度高、原材料成本低廉且结构简单,因而被认为是开发和利用可再生清洁能源的有力技术,在住宅能量存储、电动汽车驱动和智能电网等领域具备良好的应用前景。此外, CO2等温室气体的大量排放是全球变暖的主要原因, Li-CO2电池放电时可将空气中的 CO2还原固定,生成的碳材料可用作燃料和化工原料,在资源利用化上提供了新途径。 Li-CO2电池是建立在锂-空气电池的基础上。相比大气中的其他成分, H2O与 CO2对该电池的影响很大。防水膜可以减少水的影响;而在放电过程中, CO2的存在会生成 Li2CO3, Li2CO3是可以分解的。由此可见, CO2在可充放的锂电池中作为正极活性成分储能,从而被利用起来。目前 Li-CO2电池至少面临三个问题:(1)电池充放电的机理尚不完全清楚,并且以 O2和 CO2混合气为活性气体的机理与以纯 CO2为活性气体的机理是有差别的, Li2CO3的生成与分解的机制仍在探索中;(2)电解液的稳定性;(3)寻找高效的正极催化剂

    Rechargeable Mg battery has been considered a major candidate as a beyond lithium ion battery technology, which is apparent through the tremendous works done in the field over the past decades. The challenges for realization of Mg battery are complicated, multidisciplinary, and the tremendous work done to overcome these challenges is very hard to organize in a regular review paper. Additionally, we claim that organization of the huge amount of information accumulated by the great scientific progress achieved by various groups in the field will shed the light on the unexplored research domains and give clear perspectives and guidelines for next breakthrough to take place. In this Perspective, we provide a convenient map of Mg battery research in a form of radar chart of Mg electrolytes, which evaluates the electrolyte under the important components of Mg batteries. The presented radar charts visualize the accumulated knowledge on Mg battery and allow for navigation of not only the current research state but also future perspective of Mg battery at a glance.

    Daigle, Matthew J.; Kulkarni, Chetan Shrikant

    2013-01-01

    Batteries are used in a wide variety of applications. In recent years, they have become popular as a source of power for electric vehicles such as cars, unmanned aerial vehicles, and commericial passenger aircraft. In such application domains, it becomes crucial to both monitor battery health and performance and to predict end of discharge (EOD) and end of useful life (EOL) events. To implement such technologies, it is crucial to understand how batteries work and to capture that knowledge in the form of models that can be used by monitoring, diagnosis, and prognosis algorithms. In this work, we develop electrochemistry-based models of lithium-ion batteries that capture the significant electrochemical processes, are computationally efficient, capture the effects of aging, and are of suitable accuracy for reliable EOD prediction in a variety of usage profiles. This paper reports on the progress of such a model, with results demonstrating the model validity and accurate EOD predictions.

    2013-08-22

    The overall objective of this project was to develop and fabricate a multifunctional cathode with high activities in acidic electrolytes for the oxygen reduction and evolution reactions for Li-air batteries. It should enable the development of Li-air batteries that operate on hybrid electrolytes, with acidic catholytes in particular. The use of hybrid electrolytes eliminates the problems of lithium reaction with water and of lithium oxide deposition in the cathode with sole organic electrolytes. The use of acid electrolytes can eliminate carbonate formation inside the cathode, making air breathing Li-air batteries viable. The tasks of the project were focused on developing hierarchical cathode structures and bifunctional catalysts. Development and testing of a prototype hybrid Li-air battery were also conducted. We succeeded in developing a hierarchical cathode structure and an effective bifunctional catalyst. We accomplished integrating the cathode with existing anode technologies and made a pouch prototype Li-air battery using sulfuric acid as catholyte. The battery cathodes contain a nanoscale multilayer structure made with carbon nanotubes and nanofibers. The structure was demonstrated to improve battery performance substantially. The bifunctional catalyst developed contains a conductive oxide support with ultra-low loading of platinum and iridium oxides. The work performed in this project has been documented in seven peer reviewed journal publications, five conference presentations, and filing of two U.S. patents. Technical details have been documented in the quarterly reports to DOE during the course of the project.

    Market analyses information now stored in the biomass feedstock data base includes for each species: feedstock amount by region and season in tons/year; heating values in Btu/lb for those feedstock for which published data are available, and; feedstock cost in $/mm Btu. Information now stored in the product data base includes for each product: product amount by region in mm Btu/year and product cost in $/mm Btu. Biomass characterization procedures have now been developed and these will be used to characterize approximately 100 biomass species. TGA analyses will be supplemented with a pyrogram and a pyrochromatogram to further characterize each biomass. Tests were run on the PDU in the fluidized bed mode to determine the effects of particle size on reaction time. Thirteen tests were run during this quarter to verify the results from previous testing. The PDU is being modified to accommodate future sustained runs. Allocation modeling program is now functional and being tested as data is provided to the feedstock and product data banks. A mathematical model has been developed by modifying the Texaco Entrained Bed Pilot Plant Gasifier Model to simulate biomass gasification in an Entrained Bed. Results are being evaluated. Models for other reaction modes are being evaluated. A biomass economic program has been developed to provide average product fuel costs using 15 thermochemical processes.

  18. NRC quarterly [status] report

    International Nuclear Information System (INIS)

    This report covers the third quarter of calendar year 1987. The NRC licensing activity during the period of this report included the issuance of a full-power license for Beaver Valley 2 on August 14, 1987, and operating license restricted to five percent power for South Texas Unit 1 on August 21, 1987. Additional licensing delay for Shoreham is projected due to complex litigation. Also, licensing delay may occur for Comanche Peak Unit 1, because the duration of the hearing is uncertain. Although a license authorizing fuel loading and precriticality testing for Seabrook Unit 1 has been issued, there is a projected delay for low-power licensing. Full-power licensing for Seabrook Unit 1 will be delayed due to offsite emergency preparedness issues. The length of the delay is not known at this time. With the exception of Seabrook and Shoreham, regulatory delays in this report are not impacted by the schedules for resolving off-site emergency preparedness issues

    1976-03-01

    This report describes the research and management efforts, for the period January--June 1975, of Argonne National Laboratory's program on high-performance lithium/metal sulfide batteries. The batteries are being developed for two applications, off-peak energy storage in electric utility networks and electric-vehicle propulsion. The battery design for the two applications differ, particularly in cell configuration and electrode design, because of the differing performance requirements. The present cells are vertically oriented, prismatic cells with two negative electrodes of a solid lithium--aluminium alloy, a central positive electrode of iron sulfide (FeS/sub 2/ or FeS), and an electrolyte of LiCl--KCl eutectic (mp, 352/sup 0/C). The operating temperature of the cells is about 400--450/sup 0/C. Recent effort in the development of engineering-scale cells was focused on designing and fabricating vertically oriented, prismatic cells and on improving the lifetime capabilities of cells. Work on electrode development was directed toward the evaluation of the factors that influence the performance of the negative electrode and the development of new designs of vertical, prismatic iron sulfide electrodes. Materials studies included work on improving feedthroughs and separators, corrosion tests of candidate materials of construction, and postoperative examinations of cells. Cell chemistry studies included continuing investigations of cell reactions and the identification of advanced cell systems. Battery development work included the design of a battery for an electric automobile and the development of battery components. The transfer of Li--Al/FeS/sub x/ battery technology to industry is being implemented through contracts with industrial firms for the manufacture of components, electrodes, and cells.

    Wearable electronics represent a significant paradigm shift in consumer electronics since they eliminate the necessity for separate carriage of devices. In particular, integration of flexible electronic devices with clothes, glasses, watches, and skin will bring new opportunities beyond what can be imagined by current inflexible counterparts. Although considerable progresses have been seen for wearable electronics, lithium rechargeable batteries, the power sources of the devices, do not keep pace with such progresses due to tenuous mechanical stabilities, causing them to remain as the limiting elements in the entire technology. Herein, we revisit the key components of the battery (current collector, binder, and separator) and replace them with the materials that support robust mechanical endurance of the battery. The final full-cells in the forms of clothes and watchstraps exhibited comparable electrochemical performance to those of conventional metal foil-based cells even under severe folding-unfolding motions simulating actual wearing conditions. Furthermore, the wearable textile battery was integrated with flexible and lightweight solar cells on the battery pouch to enable convenient solar-charging capabilities. PMID:24164580

    This report describes the status of the advanced redox flow battery research being performed at Pacific Northwest National Laboratories for the U.S. Department of Energy’s Energy Storage Systems Program. The Quarter 1 of FY2012 Milestone was completed on time. The milestone entails completion of evaluation and optimization of single cell components for the two advanced redox flow battery electrolyte chemistries recently developed at the lab, the all vanadium (V) mixed acid and V-Fe mixed acid solutions. All the single cell components to be used in future kW-scale stacks have been identified and optimized in this quarter, which include solution electrolyte, membrane or separator; carbon felt electrode and bi-polar plate. Varied electrochemical, chemical and physical evaluations were carried out to assist the component screening and optimization. The mechanisms of the battery capacity fading behavior for the all vanadium redox flow and the Fe/V battery were discovered, which allowed us to optimize the related cell operation parameters and continuously operate the system for more than three months without any capacity decay.

    Storage of photovoltaic and wind electricity in batteries could solve the mismatch problem between the intermittent supply of these renewable resources and variable demand. Flow batteries permit more economical long-duration discharge than solid-electrode batteries by using liquid electrolytes stored outside of the battery. We report an alkaline flow battery based on redox-active organic molecules that are composed entirely of Earth-abundant elements and are nontoxic, nonflammable, and safe for use in residential and commercial environments. The battery operates efficiently with high power density near room temperature. These results demonstrate the stability and performance of redox-active organic molecules in alkaline flow batteries, potentially enabling cost-effective stationary storage of renewable energy.

    Current research projects have focused Environmental Biosciences Program (EBP) talent and resources on providing the scientific basis for risk-based standards, risk-based decision making and the accelerated clean-up of widespread environmental hazards. These hazards include trichloroethylene, low-dose ionizing radiation (gamma and neutron) and alpha radiation from plutonium. Trichloroethylene research has been conducted as a joint collaborative effort with the University of Georgia. Work on the trichloroethylene research projects has been slowed as a result of funding uncertainties. The impact of these funding uncertainties has been discussed with the United States Department of Energy (DOE). Laboratory work has been completed on several trichloroethylene risk assessment projects, and these projects have been brought to a close. Plans for restructuring the performance schedule of the remaining trichloroethylene projects have been submitted to the department. A comprehensive manuscript on the scientific basis of trichloroethylene risk assessment is in preparation. Work on the low-dose radiation risk assessment projects is also progressing at a slowed rate as a result of funding uncertainties. It has been necessary to restructure the proponency and performance schedule of these projects, with the project on Low-Dose Radiation: Epidemiology Risk Models transferred to DOE Office of Science proponency under a separate funding instrument. Research on this project will continue under the provisions of the DOE Office of Science funding instrument, with progress reported in accordance with the requirements of that funding instrument. Progress on that project will no longer be reported in quarterly reports for DE-FC09-02CH11109. Following a meeting at the Savannah River Site on May 8, 2008, a plan was submitted for development of an epidemiological cohort study and prospective medical surveillance system for the assessment of disease rates among workers at the Savannah River

    The Quarterly Environmental Data Summary (QEDS) for the fourth quarter of 1997 is prepared in support of the Weldon Spring Site Remedial Action Project Federal Facilities Agreement. The data presented constitute the QEDS. The data were received from the contract laboratories, verified by the Weldon Spring Site verification group and, except for air monitoring data and site KPA generated data (uranium analyses), merged into the data base during the fourth quarter of 1997. Air monitoring data presented are the most recent complete sets of quarterly data. Air data are not stored in the data base and KPA data are not merged into the regular data base. Significant data, defined as data values that have exceeded defined ``above normal`` level 2 values, are discussed in this letter for Environmental Monitoring Plan (EMP) generated data only. Above normal level 2 values are based, in ES and H procedures, on historical high values, DOE Derived Concentration Guides (DCGs), NPDES limits and other guidelines. The procedures also establish actions to be taken in response to such data. Data received and verified during the fourth quarter were within a permissible range of variability except for those which are detailed.

    The Energy Information Administration (EIA) prepares quarterly short-term energy supply, demand, and price projections for printed publication in January, April, July, and October in the Short-Term Energy Outlook. The details of these projections, as well as monthly updates on or about the 6th of each interim month, are available on the internet at: www.eia.doe.gov/emeu/steo/pub/contents.html. The forecast period for this issue of the Outlook extends from the fourth quarter of 1997 through the fourth quarter of 1998. Values for the fourth quarter of 1997, however, are preliminary EIA estimates (for example, some monthly values for petroleum supply and disposition are derived in part from weekly data reported in EIA`s Weekly Petroleum Status Report) or are calculated from model simulations that use the latest exogenous information available (for example, electricity sales and generation are simulated by using actual weather data). The historical energy data, compiled in the fourth quarter 1997 version of the Short-Term Integrated Forecasting System (STIFS) database, are mostly EIA data regularly published in the Monthly Energy Review, Petroleum Supply Monthly, and other EIA publications. Minor discrepancies between the data in these publications and the historical data in this Outlook are due to independent rounding. The STIFS model is driven principally by three sets of assumptions or inputs: estimates of key macroeconomic variables, world oil price assumptions, and assumptions about the severity of weather. 19 tabs.

    Electric vehicles that can't reach trolley wires need batteries. In the early 1900's electric cars disappeared when owners found that replacing the car's worn-out lead-acid battery costs more than a new gasoline-powered car. Most of today's electric cars are still propelled by lead-acid batteries. General Motors in their prototype Impact, for example, used starting-lighting-ignition batteries, which deliver lots of power for demonstrations, but have a life of less than 100 deep discharges. Now promising alternative technology has challenged the world-wide lead miners, refiners, and battery makers into forming a consortium that sponsors research into making better lead-acid batteries. Horizon's new bipolar battery delivered 50 watt-hours per kg (Wh/kg), compared with 20 for ordinary transport-vehicle batteries. The alternatives are delivering from 80 Wh/kg (nickel-metal hydride) up to 200 Wh/kg (zinc-bromine). A Fiat Panda traveled 260 km on a single charge of its zinc-bromine battery. A German 3.5-ton postal truck traveled 300 km with a single charge in its 650-kg (146 Wh/kg) zinc-air battery. Its top speed was 110 km per hour.

    International Nuclear Information System (INIS)

    The Energy Information Administration (EIA) prepares quarterly, short-term energy supply, demand, and price projections for publication in February, May, August, and November in the Short-Term Energy Outlook (Outlook). The forecast period for this issue of the Outlook extends from the first quarter of 1995 through the fourth quarter of 1996. Values for the fourth quarter of 1994, however, are preliminary EIA estimates or are calculated from model simulations using the latest exogenous information available (for example, electricity sales and generation are simulated using actual weather data). The historical energy data, compiled into the first quarter 1995 version of the Short-Term Integrated Forecasting System (STIFS) database, are mostly EIA data regularly published in the Monthly Energy Review, Petroleum Supply Monthly, and other EIA publications. Minor discrepancies between the data in these publications and the historical data in this Outlook are due to independent rounding. The STIFS database is archived quarterly and is available from the National Technical Information Service. The cases are produced using the Short-Term Integrated Forecasting System (STIFS). The STIFS model is driven principally by three sets of assumptions or inputs: estimates of key macroeconomic variables, world oil price assumptions, and assumptions about the severity of weather. Macroeconomic estimates are produced by DRI/McGraw-Hill but are adjusted by EIA to reflect EIA assumptions about the world price of crude oil, energy product prices, and other assumptions which may affect the macroeconomic outlook.

    Progress from January 1 to March 31, 1978, is reported in design of the 50 MT/year experimental facility for the preparation of high-purity silicon by the zinc vapor reduction of silicon tetrachloride in a fluidized bed of seed particles to form a free-flowing granular product. The design of the experimental facility has been concluded and sent to JPL for evaluation. It is also being critiqued by an independent pilot plant design group at BCL. Detailed analyses of equipment and construction costs have led to an estimate of $1.5 million for construction of the facility in an available building at BCL. Although the design was frozen for purposes of cost estimation, some improvements have been made since, and others are contemplatd before it is necessary to freeze the design for construction. Representative flow sheets and related equipment drawings are shown.

  8. A Desalination Battery

    KAUST Repository

    Pasta, Mauro

    2012-02-08

    Water desalination is an important approach to provide fresh water around the world, although its high energy consumption, and thus high cost, call for new, efficient technology. Here, we demonstrate the novel concept of a "desalination battery", which operates by performing cycles in reverse on our previously reported mixing entropy battery. Rather than generating electricity from salinity differences, as in mixing entropy batteries, desalination batteries use an electrical energy input to extract sodium and chloride ions from seawater and to generate fresh water. The desalination battery is comprised by a Na 2-xMn 5O 10 nanorod positive electrode and Ag/AgCl negative electrode. Here, we demonstrate an energy consumption of 0.29 Wh l -1 for the removal of 25% salt using this novel desalination battery, which is promising when compared to reverse osmosis (∼ 0.2 Wh l -1), the most efficient technique presently available. © 2012 American Chemical Society.

    2008-09-01

    This paper will describe battery technology as it relates to use in vehicular applications, including hybrid-electric vehicles (HEV), electric vehicles (EV), and plug-in-hybrid-electric vehicles (PHEV). The present status of rechargeable batteries, the requirements for each application, and the scientific stumbling blocks that stop batteries from being commercialized for these applications will be discussed. Focus will be on the class of batteries referred to as lithium batteries and the various chemistries that are the most promising for these applications. While Li-ion is expected in HEVs in the very near future, use in PHEVs are expected to be more gradual and dependent on solving the life, safety, and cost challenges. Finally, batteries for EVs remain problematic because of the range and charging-time issues.

  10. Lithium ion battery production

    International Nuclear Information System (INIS)

    Highlights: ► Sustainable battery manufacturing focus on more efficient methods and recycling. ► Temperature control and battery management system increase battery lifetime. ► Focus on increasing battery performance at low- and high temperatures. ► Production capacity of 100 MWh equals the need of 3000 full-electric cars. - Abstract: Recently, new materials and chemistry for lithium ion batteries have been developed. There is a great emphasis on electrification in the transport sector replacing part of motor powered engines with battery powered applications. There are plans both to increase energy efficiency and to reduce the overall need for consumption of non-renewable liquid fuels. Even more significant applications are dependent on energy storage. Materials needed for battery applications require specially made high quality products. Diminishing amounts of easily minable metal ores increase the consumption of separation and purification energy and chemicals. The metals are likely to be increasingly difficult to process. Iron, manganese, lead, zinc, lithium, aluminium, and nickel are still relatively abundant but many metals like cobalt and rare earths are becoming limited resources more rapidly. The global capacity of industrial-scale production of larger lithium ion battery cells may become a limiting factor in the near future if plans for even partial electrification of vehicles or energy storage visions are realized. The energy capacity needed is huge and one has to be reminded that in terms of cars for example production of 100 MWh equals the need of 3000 full-electric cars. Consequently annual production capacity of 106 cars requires 100 factories each with a 300 MWh capacity. Present day lithium ion batteries have limitations but significant improvements have been achieved recently . The main challenges of lithium ion batteries are related to material deterioration, operating temperatures, energy and power output, and lifetime. Increased lifetime

    The purpose of the program is to demonstrate the growth of up to 150 kilograms of 6'' diameter single crystal silicon ingot from one crucible by the Czochralski (CZ) method. The method being developed relies upon conventional CZ technology combined with new equipment and process designs and concepts. These concepts alternate cycles of crystal growth and hot melt replenishment and are designed to be ultimately suitable for use in a high volume production facility. A Hamco Model CG2000 RC crystal grower will be utilized for the project. Modifications will be comprehended into the puller which will allow a special chamber to be fitted. This chamber will allow for the storage of polycrystalline silicon rod to be used in the accelerated melt and crucible recharge cycle. A vacuum tight isolation valve will be incorporated into the system to allow retrieval of grown crystals and crucible melt replenishment without contamination. Additional modifications designed into the system allow for accelerated methods of melting both polycrystalline silicon rods and polycrystalline silicon chunks by the use of R.F. induction heating. Progress is reported. (WHK)

The historical energy data, compiled in the first quarter 1998 version of the Short-Term Integrated Forecasting System (STIFS) database, are mostly EIA data regularly published in the Monthly Energy Review, Petroleum Supply Monthly, and other EIA publications. Minor discrepancies between the data in these publications and the historical data in this Outlook are due to independent rounding. The STIFS model is driven principally by three sets of assumptions or inputs: estimates of key macroeconomic variables, world oil price assumptions, and assumptions about the severity of weather. Macroeconomic estimates are adjusted by EIA to reflect EIA assumptions which may affect the macroeconomic outlook. By varying the assumptions, alternative cases are produced by using the STIFS model. 24 figs., 19 tabs.

    1993-11-05

    The Energy Information Administration (EIA) prepares quarterly, short-term energy supply, demand, and price projections for publication in February, May, August, and November in the Short-Term Energy Outlook (Outlook). An annual supplement analyzes the performance of previous forecasts, compares recent cases with those of other forecasting services, and discusses current topics related to the short-term energy markets. (See Short-Term Energy Outlook Annual Supplement, DOE/EIA-0202.) The forecast period for this issue of the Outlook extends from the fourth quarter of 1993 through the fourth quarter of 1994. Values for the third quarter of 1993, however, are preliminary EIA estimates (for example, some monthly values for petroleum supply and disposition are derived in part from weekly data reported in the Weekly Petroleum Status Report) or are calculated from model simulations using the latest exogenous information available (for example, electricity sales and generation are simulated using actual weather data). The historical energy data are EIA data published in the Monthly Energy Review, Petroleum Supply Monthly, and other EIA publications.

    Lithium is one of the most promising negative electrode materials to be used for the manufacturing of batteries. It is the most electronegative material in the table of standard potentials and its low weight will facilitate a high gravimetric coulombic density. Theoretically, as high values as 6 kWh/kg could be reached for lithium based batteries. The aim of this study has been to make an inventory of what is internationally known about lithium batteries suitable for electric vehicle applications. It is representative for the development status by the summer of 1995. Both high and ambient temperature lithium batteries are described in the study even if the analysis is concentrated on the latter. Ambient temperature systems has gathered the major interest, especially from manufacturers in the `3Cs` market segment (Consumer electronics, Communications and Computers). There is no doubt, a bright future for lithium rechargeable batteries. Depending on the ambition of a national research programme, one can await the ongoing development of batteries for the 3Cs market segment or take the lead in a near-term or advanced system R and D for EV batteries. In the zero ambition EV battery programme, we recommend allocation of funds to follow the development within the 3Cs sector. The corresponding funding level is 1-2 MSEK/year granted to a stable receiver. In a low ambition EV programme, we recommend to keep a few groups active in the front-line of specific research areas. The purpose is to keep a link for communication open to the surrounding battery world. The cost level is 4-6 MSEK per year continually. In a high ambition programme we recommend the merging of Swedish resources with international EV battery R and D programmes, e.g. the EUCAR project. The research team engaged should be able to contribute to the progress of the overall project. The cost for the high ambition programme is estimated at the level 15-20 MSEK per year continually. 47 refs, 17 figs, 16 tabs

  8. Feasibility of low-cost, high-volume production of silane and pyrolysis of silane to semiconductor-grade silicon. Low Cost Silicon Solar Array Project. Quarterly progress report, January--March 1978

    The purpose of the silane production program is to determine the feasibility and practicality of high-volume, low-cost production of silane (SiH/sub 4/) as an intermediate for obtaining solar-grade silicon metal. The process is based on the synthesis of SiH/sub 4/ by the catalytic disproportionation of chlorosilanes resulting from the reaction of hydrogen, metallurgical silicon, and silicon tetrachloride. The goal is to demonstrate the feasibility of a silane production cost of under $4.00/kg at a production rate of 1000 MT/year. The objective of the silicon production program is to establish the viability and economic feasibility of manufacturing semiconductor-grade polycrystalline silicon through the pyrolysis of silane. The silane-to-silicon conversion is to be investigated in a fluid bed reactor and a free space reactor. The purpose of the process design program is to provide JPL with engineering and economic parameters for an experimental facility capable of producing 25 metric tons of silicon per year by the pyrolysis of silane gas. An ancillary purpose is to estimate the cost of silicon produced by the same process on a scale of 1000 metric tons per year. The capacitive fluid-bed heating program is exploring the feasibility of utilizing electrical capacitive heating to control the fluidized silicon bed temperature during the heterogeneous decomposition of silane. In addition, a theoretical fluid-bed silicon deposition model is being developed to be used in a design of a fluid-bed pyrolysis process scheme. Research progress is described in detail. (WHK)

  9. Continuous Czochralski growth: silicon sheet growth development of Large Area Silicon Sheet Task of the Low-Cost Silicon Solar Array Project. Second quarterly progress report, January 1--March 31, 1978

    Energy Technology Data Exchange (ETDEWEB)

    1978-01-01

    This project is directed toward the development of equipment and processes to produce single crystal solar silicon by a continuous Czochralski (CZ) method. ''Continuous'' is defined as the production of at least 100 kilograms of crystal from a single melt container. The approach to be taken is to suitably modify a Hamco CG2000 crystal grower to demonstrate that continuous CZ growth is feasible by the periodic replenishment of the melt container and the removal of grown crystals. The crystal growth facility is now complete with the exception of the poly weight/recharge system. Installation of this device on the grower will require disassembly of the facility to modify the growth chambers. In the meantime, hot filling experiments are being conducted by attaching poly rod material to the seed lift mechanism. The work has progressed to the point where a suitable means of melt replenishment has been demonstrated. A poly-crystalline rod of silicon can be lowered into the crucible and melted at rates of over 14 kg/hr. Using this method of hot filling, a 12'' x 9'' high crucible was charged with 25 kg of silicon and a zero dislocation, 22 kg crystal 11.4 cm diameter, 87 cm long, was grown. This demonstrates that five crystals grown from a 12 inch crucible can satisfy the continuous CZ criterion. A growth rate of 7.3 cm/hr was achieved corresponding to a continuous throughput of 1.1 kg/hr. An economic model using the SAMICS/IPEG guidelines has shown that the add-on cost of CZ crystal growth can meet the 1982 goals without any technical breakthroughs, but an add-on cost reduction of approximately 50% is necessary to meet the 1986 goal, assuming reasonable slicing yields.

    These batteries are being developed for electric vehicle propulsion and for stationary energy storage applications. The present battery cells, which operate at 400 to 450/sup 0/C, are of a vertically oriented, prismatic design with a central positive electrode of FeS or FeS/sub 2/, two facing negative electrodes of lithium--aluminum alloy, and an electrolyte of molten LiCl--KCl. Testing and evaluation of industrially fabricated cells is continuing. During this period, Li--Al/FeS and Li--Al/FeS/sub 2/ cells from Eagle-Picher Industries were tested, and tests of Li--Al/FeS cells from Gould Inc. were initiated. The cells are tested individually and in parallel and series battery configurations. These tests provide information on the effects of cell design modifications and alternative materials. Improved electrode and cell designs are being developed and tested at ANL, and the more promising designs are incorporated in the industrially fabricated cells. Among the concepts receiving major attention are carbon-bonded positive electrodes, scaled-up stationary energy storage cell designs, additives to extend electrode lifetime, and alternative electrode separators. The materials development efforts include the development of a new lightweight electrical feedthrough; investigations of new separator materials (e.g.,Y/sub 2/O/sub 3/ powder, Y/sub 2/O/sub 3/ felt, and porous, rigid ceramics); corrosion tests of materials for cell components; and postoperative examinations of cells. The cell chemistry studies were directed to discharge mechanisms of FeS electrodes, emf measurements of the LiAl/FeS/sub 2/ couple at various states of discharge, and studies of other transition-metal sulfides as positive-electrode materials. The advanced battery effort mainly concerned the use of calcium alloys for negative electrode and transition metal sulfides or oxides for the positive electrode. 13 figures, 18 tables.

    A need exists for a standardized battery of human performance tests in order to measure the effects of various treatments. The present paper reports on progress in such a program, funded jointly by NASA and the Navy. Three batteries are available which differ in length (7.5, 15, and 30 minutes), and number of tests in the battery (3, 10, and 15). All tests are implemented on a portable, lap-held, briefcase-sized microprocessor (NEC PC 8201A). Performances measured include information processing, memory, visual perception, reasoning, motor skills, etc. Current programs are underway to determine norms, reliabilities, stabilities, factor structure of tests, comparisons with marker tests, apparatus suitability, etc.

    The highlight for the first quarter was the presentation of research progress and findings at the DPI Symposium on March 5, 1997. Since that presentation, additional progress was slowed down due to the decreased budget funding for year two, and consequently, the decrease in time-effort of the principal investigators. This report summarizes the progress in each of the topical areas to date. A research article has been prepared for publication for the Optical Character Recognition project; two progress reports are included for the Logical Analysis project; and two progress reports for the Knowledge Representation project. Research activities for the Tipster Technology project will resume this fall.

  18. Isotope heated thermal batteries

    International Nuclear Information System (INIS)

    A deferred action thermal battery is described that includes a quantity of radioactive isotope normally positioned so that only a small part of the thermal energy generated by the isotope is received by the battery, but adapted, when the battery is rendered active, to be moved automatically to a position where a large part of the thermal energy is received. The battery may comprise a chamber containing its cells and a second chamber part of which is remote from the cells for normal storage of the isotope and part of which is adjacent to the cells; the isotope is moved to the latter part when the battery is activated. The cell chamber is preferably toroidal and surrounds the second portion of the isotope chamber. The isotope may be contained in a carriage held by a retaining means adapted for release when the battery is activated, resilient means then moving the carriage to the active position. The retaining means may be a wire that disintegrates on the passage of electric current, the current also igniting a combustible composition to activate the battery. The object is to provide thermal batteries having an extended life. (U.K.)
