Abstract. A compressed air energy storage (CAES) system is an electricity storage technology under the category of mechanical energy storage (MES) systems, and is most appropriate for large-scale use and longer storage applications. In a CAES system, the surplus electricity to be stored is used to produce compressed air at high pressures.

Large-scale, long-period energy storage technologies primarily encompass compressed air energy storage (CAES), pumped hydro energy storage (PHES), and hydrogen energy storage (HES). Among these, PHES is heavily reliant on environmental factors, while HES faces limitations in large-scale application due to high costs.
Pumped hydro energy storage (PHES), compressed air energy storage (CAES), and liquid air energy storage (LAES) are three large-scale energy storage methods [8]. Among these, PHES harnesses the gravitational potential energy of water for storing electricity.

3.1.5 Compressed Air Storage. 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.
