Technology Strategy Assessment
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 distributioncenters. In response to demand, the stored energy can be discharged by expanding the stored air with a turboexpander generator.
