摘要: 抽水蓄能技术是目前广泛应用的大规模储能技术之一,传统抽水蓄能技术需要特殊的地理条件建造两个水库,投资成本高、破坏生态环境,并且对淡水资源依赖严重。海水抽水蓄能技术利用海洋作为上水库或下水库,水位变幅小,减少了水库建设及其投资成本,解决了传统抽水蓄能电站对淡水资源的利用问题以及环境破坏问题,对于临海和淡水资源缺乏的岛国和城市具有非常广阔的发展前景。本文介绍了海水抽水蓄能系统的工作原理,全面分析了海水抽水蓄能系统的研究进展和应用情况,总结了开发海水抽水蓄能系统存在的技术与应用问题,并对其应用前景与发展潜力进行了展望,提出海水抽水蓄能系统与可再生能源的耦合将是其近期主要的发展方向。

Abstract: Pumped hydro energy storage (PHES) is one of most widely used large-scale energy storage technologies. The traditional pumped hydro energy storage technology requires specific geographic conditions to construct the upper and lower reservoirs, leading to a high investment, damages to the ecological environment and heavily dependence on the use of fresh water. Seawater pumped hydro energy storage (SPHES) technology uses seawater, and the sea as the upper or the lower reservoir. The advantages of such technology include small variation of water level, low construction cost and small influence on environment, and therefore has great potential for applications in islands where fresh water is lacking. This paper will first explain the working principles of the SPHES technology, followed by a review of the state-of-the-art development in the area. Finally, potential applications in China and associated challenges are discussed.
