Document Type and Number:
WIPO Patent Application WO/2023/228938
Kind Code:
A1
Abstract:
[Problem] To provide an economical compressed air energy storage (CAES) method for effectively utilizing the volume space of an air storage unit in order to reduce equipment cost in CAES equipment. [Solution] An air storage unit 300 is formed by a plurality of containers 301, and a film having a shape-changeable space is disposed inside in each container. A buffer gas is filled in advance into a space on one surface side of the film inside each container in an air compression step, air is stored in a space on the other surface side of the film, the buffer gas is converted into a fluid having reduced volume to increase the air quantity stored in the space on the other surface side of the film, and this fluid is heated and vaporized in an air expansion step to reduce the air quantity remaining on the space on the other surface side of the film. The usable volume of air storage unit space is expanded in this manner, which makes it possible to increase the net air storage amount in the internal space of each container 301.
