Abstract The development history, cavern composition and role of underground compressed gas energy storage technology were systematically introduced, and the development status of underground lined cavern technology was discussed. This paper systematically analyzed the research progress of three key problems of underground lined caverns, namely ultimate storage pressure, thermodynamic effects in the process of gas injection and production, and sealing performance of cavern lining, summarized the existing research results, pointed out its limitations, and put forward suggestions for the future research direction of underground lined caverns.
