S. Hari Charan Cherukuri, in Journal of Energy Storage, 2021 Compressed Air Energy Storage (CAES) is an option in which the pressure energy is stored by compressing a gas, generally air, into a high pressure reservoir. The compressed air is expanded into a turbine to derive mechanical energy and hence run an electrical generator.
The round tip efficiency of Isothermal compressed air energy storage system is high compared to that of other compressed air energy storage systems. The temperature produced during compression as well as expansion for isothermal compressed air energy storage is deduced from heat transfer, with the aid of moisture in air.
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.
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 .
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. Three main concepts are researched; diabatic, adiabatic and isothermal.
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.
