能源危机和温室效应促进了可再生能源的利用，储能技术是解决太阳能、风能波动问题的重要手段。压缩空气储能（Compressed Air Energy Storage, CAES）技术是仅次于抽水蓄能的第二大蓄能技术。目前CAES多是通过洞穴实现，其主要缺点是对地质要求较高，合适的洞穴数量有限，为扩大其应用，可使用地下咸水含水层作为储层。本文介绍了 CAES 电站的工作原理、优缺点及各国的发展现状，并分析了利用地下咸水含水层进行压缩空气储能的可行性、优点及一些问题与技术方法，如储层内残余烃的影响、氧化与腐蚀作用、颗粒的影响及缓冲气的选择，表明含水层CAES将是拓宽CAES应用的重要途径。

Energy crisis and greenhouse effect have promoted the utilization of renewable energy. Energy storage technology is an indispensable part in solving the fluctuation problem for the utilization of solar energy, wind energy, etc. Compressed air energy storage (CAES) technology is the second large energy storage potential just after the pumped hydro storage technology. At present, reservoirs for the CAES are usually underground caverns which are highly limited by geological conditions. Using saline aquifer as the storage reservoir can extend the utilization of the CAES. Herein, the operation principle, advantages and disadvantages of CAES plant are introduced. The feasibility, problems and the key technologies used in aquifer CAES such as the residual hydrocarbons, oxidation, corrosion, particulates and the choice of cushion gas are discussed. This study concludes that the use of saline aquifer as storage reservoir will be an important way to extend the application of CAES.
