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 .
Schematic diagram of a compressed air energy storage (CAES) Plant. Air is compressed inside a cavern to store the energy, then expanded to release the energy at a convenient time. [...] Driven by global concerns about the climate and the environment, the world is opting for renewable energy sources (RESs), such as wind and solar.
Overview of compressed air energy storage Compressed air energy storage (CAES) is the use of compressed air to store energy for use at a later time when required , , , , . Excess energy generated from renewable energy sources when demand is low can be stored with the application of this technology.
There are several compression and expansion stages: from the charging, to the discharging phases of the storage system. Research has shown that isentropic efficiency for compressors as well as expanders are key determinants of the overall characteristics and efficiency of compressed air energy storage systems .
