The air is compressed using surplus energy and stores the energy in the form of compressed air. When energy demand exceeds supply, the air is released and heated to drive an expansion turbine to generate electricity. CAES systems in operation in Germany and the United States are both using salt domes with volumes of several 1 Mm
In low demand period, energy is stored by compressing air in an air tight space (typically 4.0~8.0 MPa) such as underground storage cavern. To extract the stored energy, compressed air is drawn from the storage vessel, mixed with fuel and combusted, and then expanded through a turbine.

Introduction. Adiabatic compressed air energy storage (ACAES) is frequently suggested as a promising alternative for bulk electricity storage, alongside more established technologies such as pumped hydroelectric storage and, more recently, high-capacity batteries, but as yet no viable ACAES plant exists.
Compressing and decompressing air introduces energy losses, resulting in an electric-to-electric efficiency of only 40-52%, compared to 70-85% for pumped hydropower plants, and 70-90% for chemical batteries. The low efficiency is mainly since air heats up during compression.
