Abstract: In the context of global energy transition, renewable energy has been vigorously developed due to its significant advantages of cleanliness and sustainability. However, its power generation is constrained by natural conditions. To solve this problem, compressed air energy storage technology has emerged as the core means to solve the problem of renewable energy consumption with its unique energy storage characteristics, flexible system configuration, and wide applicability. This article comprehensively introduces the storage facilities, working principles, and application status of compressed air energy storage, with a focus on analyzing the characteristics, advantages, and disadvantages of supplementary combustion, adiabatic, thermal storage, isothermal, liquid, and supercritical compressed air energy storage technologies. By reviewing domestic and foreign demonstration projects, the development trend and coupling application with renewable energy, which of CAES technology are explored providing theoretical guidance for the design of compressed air energy storage systems in the future.

Key words: Compressed air energy storage technology, Gas storage facilities, Application analysis
