Title: Underground energy-storage program overview

Conference ·
OSTI ID:6762083

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 of 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.
