The technology of storing energy by compressing air and keeping it in a suitable reservoir. Surplus electrical energy is used to compress the air, which is stored in an underground cavern or in a special container. Old mines are often used as suitable spaces. When needed, the air is released on an air turbine to produce electricity.

The special thing about compressed air storage is that the air heats up strongly when being compressed from atmospheric pressure to a storage pressure of approx. 1,015 psia (70 bar). Standard multistage air compressors use inter- and after-coolers to reduce discharge temperatures to 300/350°F (149/177°C) and cavern injection air temperature …

The 110 MW McIntosh plant can operate for up to 26 h at full power. The compressed air is stored in a salt cavern. A recuperator is operated to reuse the exhaust heat energy. This reduces the fuel consumption by 22–25% and improves the cycle efficiency from ∼42% to ∼54%, in comparison with the Huntorf plant.

CAES is a form of energy storage that involves compressing air and storing it under pressure, often in underground reservoirs, such as caverns or aquifers. When needed, the compressed air is released, driving a turbine to generate electricity. This process can be highly efficient, with some systems reaching up to 70% efficiency.
