Recently, a major breakthrough has been made in the field of research and development of the Compressed Air Energy Storage (CAES) system in China, which is the completion of integration test on the world-first 300MW expander of advanced CAES system marking the smooth transition from development to production.
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.
Most of the world's grid energy storage by capacity is in the form of pumped-storage hydroelectricity, which is covered in List of pumped-storage hydroelectric power stations. This article list plants using all other forms of energy storage.
Compressed-air energy storage can also be employed on a smaller scale, such as exploited by air cars and air-driven locomotives, and can use high-strength (e.g., carbon-fiber) air-storage tanks.
