The Influence of Heat Exchange in Gas Storage Tanks in the Compressed Air Energy Storage System

As the core energy storage component in compressed air energy storage systems, the changes in temperature, pressure, comprehensive heat transfer coefficient and other parameters during its operation have a significant impact on the energy storage density of the gas storage, which in turn affects the entire process design of the compressed air energy storage system. This study used empirical formulas and finite element simulation methods to analyze the charging/discharging process of gas storage facilities and investigate the impact of changes in gas storage facilities on the overall design of the compressed air energy storage system. The results indicated that the comprehensive heat transfer coefficient of the gas storage increased with the increasing charging and discharging flow rate of the gas storage. The energy density of the gas storage decreased with the increase of the gas discharging flow rate of the gas storage. This study provided a new method of multi-research coupling for compressed air energy storage systems, which was beneficial for improving the accuracy of compressed air energy storage system design.
