China is currently in the early stage of commercializing energy storage. As of 2017, the cumulative installed capacity of energy storage in China was 28.9 GW [5], accounting for only 1.6% of the total power generating capacity (1777 GW [6]), which is still far below the goal set by the State Grid of China (i.e., 4%–5% by 2020) [7].
Compressed-air energy storage (CAES) is a commercialized electrical energy storage system that can supply around 50 to 300 MW power output via a single unit (Chen et al., 2013, Pande et al., 2003).

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.
The operation principle behind compressed air energy storage is simple. When there is excess electricity in a system, a fluid is compressed in a large impermeable cavity. The fluid remains in the cavity at high pressure until there is a need for power.
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.
The use of compressed air storage as an adjunct to the power grid began with the construction of the Huntorf power plant which was built in Germany in 1978 but only operated commercially for 10 years. A second CAES plant was built by the Alabama Electric Cooperative in the United States and entered service in 1991.
Compressed air energy storage systems may be efficient in storing unused energy, but large-scale applications have greater heat losses because the compression of air creates heat, meaning expansion is used to ensure the heat is removed [, ]. Expansion entails a change in the shape of the material due to a change in temperature.
