Abstract:

Compressed air energy storage (CAES) is acknowledged to be the most promising physical energy storage technology. In CAES system, the gas storage device as key link has important influence on the efficient, stable, and safe operation of system. In recent years, with the rapid development of CAES technology, the research of gas storage devices has attracted much attention. The characteristics of gas storage devices mainly depend on their material properties, so they were classified according to material, including underground cavern, artificial cavern, metal gas storage device and composite material gas storage device. The application of different types of gas storage devices were discussed emphatically. The contrastive analysis showed that underground cavern had large scale and low cost, but depended on special geological and geographical conditions. Therefore, new gas storage devices with flexible layout characteristics should be explored actively. Further, the challenges faced by current gas storage devices were revealed in this work. The key points and difficulties in establishing the precise thermodynamic model of gas storage device, evaluating the stability of underground cavern and studying the structure characteristics of composite material gas storage devices were discussed respectively. Moreover, the development and research hotspots of gas storage devices were also prospected and summarized. Finally, the purpose of this work is to offer guidance for reasonable selection and theoretical research of gas storage devices in CAES system and to provide reference for improving the performance of gas storage devices and CAES system.
