Compressed air energy storage is a new form of large-scale and long-term physical energy storage. Gas storage is a crucial component of compressed air energy storage system. The characteristics of common gas storage devices are summarized, and the underground artificial chamber is discussed in detail. The advantages of underground artificial chamber of compressed air energy storage system compared with other types of gas storage are summarized. The design factors such as bearing structure, sealing system and heat transfer management system of underground artificial chamber are analyzed. The key technologies affecting operation of the underground artificial chamber such as site selection, buried depth and pressure design criteria are analyzed and discussed. The evaluation method and evaluation indexes of the factors affecting stable operation of the artificial chamber are put forward. On this basis, the future development direction of compressed air energy storage underground artificial chamber is prospected, which provides a reference for rational design and stable operation of the underground artificial chamber.
