Compressed air energy storage (CAES) is one of the many energy storage options that can store electric energy in the form of potential energy (compressed air) and can be deployed near central power plants or distribution centers. In response to demand, the stored energy can be discharged by expanding the stored air with a turboexpander generator.
The number of sites available for compressed air energy storage is higher compared to those of pumped hydro [, ]. Porous rocks and cavern reservoirs are also ideal storage sites for CAES. Gas storage locations are capable of being used as sites for storage of compressed air .
Gas storage locations are capable of being used as sites for storage of compressed air . Today, several research activities are being carried out to explore the application of CAES on small scale projects, following their successful integration on large scale renewable energy systems , , , .

(1) explains how electrical energy can be stored as exergy of compressed air in an idealized reversed process. The Adiabatic method achieves a much higher efficiency level of up to 70%. In the adiabatic storage method, the heat, which is produced by compression, is kept and returned into the air, as it is expanded to generate power.
