  • The Thermal Energy Storage Program of the U.S. Department of Energy (DOE) promotes energy savings and fuel substitution by developing and helping to commercialize technologies for storing heat or cold. The sources of energy include industrial and utility waste heat as well as primary sources such as solar, geothermal, nuclear, and fossil fuels. The primary energy sink involved in the storage of ''cold'' is winter chilled air. The program emphasizes applications which possess a potential near-term impact and those which relate to solar and other dispersed energy technologies. These applications include seasonal storage for building heating and cooling; daily storagemore » for active or passive solar and conventional heating and cooling; heat storage for solar thermal electric power generation; and storage for recovery of industrial or utility waste heat. The program has a budget of $16.5 million for FY 1981. Program management for policy, planning, and budget issues is provided by Division of Thermal and Mechanical Energy Storage Systems within the Office of Advanced Conservation Technologies. Detailed project management is provided by field organizations, including Brookhaven National Laboratory for chemical heat pumps; Oak Ridge National Laboratory for thermal energy storage for building heating and cooling, heat recovery for district heating, and thermal energy storage for industrial retrofit; Pacific Northwest Laboratory for seasonal thermal energy storage; Sandia National Laboratory, Livermore, for thermal energy storage for solar thermal power generation; and Solar Energy Research Institute for applied research on thermal energy storage and heat transport. The program includes a diverse range of individual projects, from analytic studies of thermochemical pipelines, through benchscale laboratory investigation of individual phase-change materials, to large-scale field testing of aquifer storage.« less
  • A crucial role in the National Energy Plan will be played by the development of energy-storage technologies and their use in a variety of applications, such as power storage for utility load leveling and thermal storage for buildings and manufacturing processes. DOE programs encompass both stationary and mobile applications, many of which give near-term assistance to energy-conservation problems. Federal involvement is necessary because many of the technologies involve high-risk research and development investments which would otherwise slow market penetration. DOE-funded programs in central storage include compressed air, underground pumped hydro, battery packs, waste heat and coolness, lowlead hydroelectric generation ofmore » hydrogen, and customer storage studies. Work on dispersed storage technologies includes a variety of vehicle batteries, flywheels, and hybrid concepts for vehicles. 5 figures. (DCK)« less
  • The objective of this program is to reduce technical and economic risks obstructing commercial development of underground energy storage concepts promising more effective and efficient utilization of energy resources. Primary concepts are Seasonal Thermal Energy Storage (STES) and Compressed Air Energy Storage (CAES). STES objectives include characterization and mitigation of STES concept technical deficiencies and uncertainties and evaluation of economic features. CAES objectives include development of stability criteria for CAES reservoirs and analysis and development of promising second-generation CAES systems. Characterization of the performance of TES systems at injection temperatures of less than 85/sup 0/C is nearly complete. Studies ofmore » injection and storage at temperatures up to 150/sup 0/C have been initiated and will be continued through FY 1983. Studies of nonaquifer STES systems including cavern and ice storage systems have been conducted and will continue in FY 1983. Stability criteria and guidelines documents have been published for salt and hard rock CAES reservoirs. All design and construction on the Pittsfield Aquifer Field Test will be completed by the end of FY 1982 and bubble development and air cycling will be conducted in the first six months of FY 1983. A preliminary screening of materials for use in thermal storage units of adiabatic and hybrid CAES systems has been completed. Two materials, Denstone (a registered product of the Norton Company) and Dresser basalt, survived screening tests and are recommended for additional long term testing.« less
  • Sandia Laboratories is charged with advancing components technology for flywheel energy storage systems. Portions of this work are being done in-house, the balance on contract with outside agencies. At this writing, seventeen specific efforts can be identified. These comprise seven tasks under the heading of composite wheel development, four under bearings, three under vacuum seals, and three under general vacuum technology.
