Evaluation of thermal-energy storage media for advanced compressed-air energy-storage systems
Proposed designs of adiabatic and hybrid compressed air energy storage (CAES) plants have utilized sensible heat storage systems to store the heat developed during the air compression phase of the operation cycle for subsequent use during the power generation phase. This study was performed to experimentally evaluate the performance and durability of several heat storage materials proposed for these systems. Materials considered were: (1) 3/8 in. sintered iron oxide pellets; (2) 1/2-in. Denstone spheres; (3) 1-in. cast iron alloy balls; and (4) crushed rock. The results indicated that, from the standpoint of performance and durability, Denstone, cast iron containing 27% or more chromium, or crushed rock (Dresser basalt) would be satisfactory. However, considering material costs in addition to performance and durability, crushed rock would probably be the most desirable heat storage material for these types of CAES plants.
