Schematic diagram of a compressed air energy storage (CAES) Plant. Air is compressed inside a cavern to store the energy, then expanded to release the energy at a convenient time.
Customer Service
In diabatic compressed air energy storage systems, off-peak electricity is transformed into energy potential for compressed air, and kept in a cavern, but given out when demand is high. Fig.
