What is Compressed Air Energy Storage? Compressed air energy storage (CAES) is a form of mechanical energy storage that makes use of compressed air, storing it in large under or above-ground reservoirs. When energy is needed, the compressed air is released, heated, and expanded in a turbine to generate electricity.
