Compressed Air Energy Storage (CAES): A technology that stores energy by compressing air and releasing it to generate electricity when needed. Compressor: A device that compresses air for storage in a CAES system. Storage Reservoir: A large underground or above-ground space where compressed air is stored.
The air, which is pressurized, is kept in volumes, and when demand of electricity is high, the pressurized air is used to run turbines to produce electricity . There are three main types used to deal with heat in compressed air energy storage system .
Appendix B presents an overview of the theoretical background on compressed air energy storage. Most compressed air energy storage systems addressed in literature are large-scale systems of above 100 MW which most of the time use depleted mines as the cavity to store the high pressure fluid.
Air is compressed using compressors and is stored in the storage tanks. Over the surface storage tanks are used for lower rating and underground storage tanks are preferred in case of very high capacity plants. The compressor is run by the motor generator to which the excess available energy is fed.
Compressed air energy storage has a significant impact on the energy sector by providing large-scale, long-duration energy storage solutions. CAES systems can store excess energy during periods of low demand and release it during peak demand, helping to balance supply and demand on the grid.
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 .

Most compressed air systems up until this point have been diabatic, therefore they do transfer heat — and as a result, they also use fossil fuels. 2 That''s because a CAES system without some sort of storage for the heat produced by compression will have to release said heat…leaving a need for another source of always-available energy to warm turbines …
