盐穴在地下能源存储领域的应用及发展

Utilization and Development of Salt Caverns in the Field of Energy Underground Storage

盐岩具有较低的渗透性、良好的蠕变特性及损伤恢复功能。盐穴是能源地下存储的良好介质,广泛应用于天然气、原油、液态碳氢化合物等的存储;也可以进行压缩空气蓄能和氢气存储蓄能,存储转化可再生能源;同时可应用于工业废料、有害废料的处置及二氧化碳封存等。综述了盐穴在地下能源领域的应用情况及基本原理,展望了盐穴的技术发展趋势。阐述了中国盐穴能源储库起步较晚、资源有限、技术难点多、发展与挑战并存的现状。

With the low permeability,good creep and damage recovery of rock salt , salt cavern is a good medium of underground energy storage, and thus is used for gas, crude oil and liquid hydrocarbon storage. Salt cavern can also be used for compressed air energy storage and hydrogen storage, and storing and transforming surplus energy form renewable energy sources. At the same time, salt caverns are also widely used in the industrial waste, hazardous waste disposal, carbon dioxide sequestration and so on. This paper reviews the application of underground salt cavern in the field of energy underground storage and the basic principle, the technical development trend of salt caverns, and expounds the development status of China＇s energy storage in salt caverns.
