压缩空气储能(compressed air energy storage,CAES)技术是一种新型的物理储能技术,也是一种具有广阔发展前景的大规模储能发电技术.大规模压缩空气储能通常需要配置大容量的地下储气装置.在现有的地下储气库类型中,内衬式人工硐室地下储气库因其选址灵活、限制条件少成为近年来的研究热点.在当前国内对大规模CAES技术需求迫切的背景下,对人工硐室储气库的理论研究成果和技术发展现状进行了全面梳理和评述,分析了现有地下储气库稳定性分析理论、内衬硐室密封方案和热力学过程分析方法等的优点和不足,并讨论了内衬式人工硐室储气库工程的设计要点和注意事项.最后,提出了影响内衬式人工硐室储气行业发展面临的挑战.
Abstract
Compressed air energy storage(CAES)technology is a new type of physical energy storage and a kind of large-scale energy storage technology for power generation with broad development prospects.Large-scale CAES usually requires high-capacity underground gas storage devices.Among the existing types of underground compressed air storage reservior,the underground cavern with liner and air sealed layer has become a research hotspot in recent years because of its advantages such as easy site selection and minimal site constraints.Under the background of the urgent need for large-scale CAES technology in China,this paper comprehensively summarized and commented on the theoretical research results and technical development status of man-made cavern for gas storage,discussed the advantages and disadvantages of the existing stability analysis theory of underground gas storage cavern,sealing scheme of lined cavern and thermodynamic process analysis method.The key design points and critical issues that require attention in the development of the man-made underground lined caverns for air storaged project are also discussed.Finally,the challenges affecting the industry development of compressed air energy storage with lined rock caverns were put forward.
