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.
