Compressed air energy storage

Compressed air energy storage or simply CAES is one of the many ways that energy can be stored during times of high production for use at a time when there is high electricity demand.

What is compressed air energy storage (CAES)?

Compressed air energy storage (CAES) stores energy by using excess electricity to compress and pump air into underground storage facilities such as salt caverns. The stored air is later released to drive turbines and generate electricity during peak demand periods. There are three main types of CAES systems - diabatic, adiabatic, and isothermal.

What is a compressed air energy storage system?

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.
