The application of elastic energy storage in the form of compressed air storage for feeding gas turbines has long been proposed for power utilities; a compressed air storage system with an underground air storage cavern was patented by Stal Laval in 1949. Since that time, only two commercial plants have been commissioned; Huntorf CAES, Germany
Compressed air energy storage (CAES) is a form of mechanical energy storage that makes use of compressed air, storing it in large under or above-ground reservoirs. When energy is needed, the compressed air is released, heated, and expanded in a turbine to generate electricity. CAES systems are capable of storing large amounts of energy for extended periods, making them
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.
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

In response to demand, the stored energy can be discharged by expanding the stored air with a turboexpander generator.
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 as of 2024.
Compressed air energy storage may be stored in undersea caves in Northern Ireland. In order to achieve a near- thermodynamically-reversible process so that most of the energy is saved in the system and can be retrieved, and losses are kept negligible, a near-reversible isothermal process or an isentropic process is desired.
ACCEPTED MANUSCRIPT Sobolik et al., 2019;Tarkowski, 2019). In particular, three commercial compressed-air energy storage (CAES) facilities currently exist in Germany, the USA, and Canada, each exploiting salt caverns (Kim et al., 2023).
