Compressed Air Energy Storage
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.
