A cost analysis of packed beds for thermal-energy storage (TES) in an adiabatic compressed-air-energy storage system is given. Capital costs based on the conceptual design of a TES unit are estimated and their sensitivity to system parameter variation is studied.

Two TES conceptual designs were considered for: an excavated cavity, and an abandoned mine. A cost comparison is made. Get this from a library. Cost analysis of packed beds for thermal-energy storage. [Nigel I Hamilton; United States.
