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.

Hydraulic systems are probably preferable. At small scale a hydraulic accumulator can be used to store pressure. At large scale potential energy (reservoir or water tower) can be used to store hydraulic pressure. Incompressible pumping and expansion are much more efficient. Energy density should be better as well. 1.
