摘要:

压缩空气储能被认为是最具发展潜力的大规模物理储能技术,储气装置作为压缩空气储能系统的关键环节,对系统高效、稳定和安全运行具有重要影响。近些年来,随着压缩空气储能技术的快速发展,储气装置的研究备受人们关注。储气装置的特点主要取决于其材料属性,因此本文根据材料不同对储气装置进行分类,并着重论述了天然地下洞穴储气、人造洞室储气、金属材料储气以及复合材料储气的应用。对比分析表明,天然地下洞穴储气规模大、成本低,但是依赖于特殊地质和地理条件,因此应积极探索具有灵活布置特性的新型储气方案。进一步地,本文阐述了不同类型储气装置当前所面临的挑战,分别探讨了储气装置精准热力学模型建立、地下洞穴储气稳定性评价以及复合材料储气结构特性研究中亟需解决的重点和难点,并对未来储气装置的发展趋势以及研究热点进行了展望和总结。旨在为压缩空气储能系统储气装置的选型和理论研究提供指导,为改善压缩空气储能系统和储气装置性能提供借鉴。

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.

Key words: compressed air energy storage, gas storage device, thermodynamic model, structural characteristic, stability
