Compressed air energy storage (CAES) is one of the many energy storage options that can store electric energy in the form of potential energy (compressed air) and can be deployed near central power plants or distribution centers. In response to demand, the stored energy can be discharged by expanding the stored air with a turboexpander generator.

Starting in 1896, Paris used compressed air to power homes and industry. Beginning in 1978 with the first utility-scale diabatic CAES project in Huntorf, Germany, CAES has been the subject of ongoing exploration and development for grid applications. The U.S. Department of Energy (DOE) has a history of supporting CAES development.
