储热技术基础(Ⅱ)——储热技术在电力系统中的应用

Potential applications of thermal energy storage in electric power generation sector (Ⅱ)

简要介绍了储热技术在电力系统中最有潜力的四种具体应用技术,包括太阳能热发电、压缩空气储能、深冷储能、热泵储电,指出了太阳能热发电储热技术在短期内具有很大发展潜力,目前双罐式液体显热储热(储冷)具有较好的整体效率,将在电力系统储热技术中发挥重要的作用。

This article briefly introduces four potential thermal energy storage （TES） applications in electric power generation sector, including solar power generation, compressed air energy storage （CAES）, cryogenic energy storage and heat pump technology. It concludes that TES is promising in concentrated solar power （CSP） generation in the near future. Current two-tank sensible thermal storage technology has a good overall efficiency, and is expected to play an important role particularly in power generation sector.
