Compressed-air energy storage (CAES) is a way to store energy for later use using compressed air. At a utility scale, energy generated during periods of low demand can be released during peak load periods. The first utility-scale CAES project was in the Huntorf power plant in Elsfleth, Germany, and is still operational . The Huntorf plant was initially developed as a load balancer for fossil-fuel-generated electricity

Compressed air energy storage (CAES) is a way to store energy generated at one time for use at another time. At utility scale, energy generated during periods of low energy demand (off-peak) can be released to meet higher demand (peak load) periods. Since the 1870''s, CAES systems have been deployed to provide effective, on-demand energy for
Diabatic storage systems utilize most of the heat using compression with intercoolers in an energy storage system underground. During the operation, excess electricity is used to compress the air into a salt cavern located underground, typically at depths of 500–800 m and under pressures of up to 100 bars.
