COMPRESSED-AIR-STORING POWER GENERATION DEVICE AND COMPRESSED-AIR-STORING POWER GENERATION METHOD

Title:

COMPRESSED-AIR-STORING POWER GENERATION DEVICE AND COMPRESSED-AIR-STORING POWER GENERATION METHOD

Document Type and Number:

WIPO Patent Application WO/2018/198724

Kind Code:

A1

Abstract:

A compressed-air-storing power generation device 1 comprises an inert gas source 25 that supplies an inert gas, an inert gas flow channel system 6, and a flow-channel-switching part 28. The inert gas flow channel system 6 fluidly connects to each other a gas phase part 17b of a high-temperature heat storage part 17, a gas phase part 18b of a low-temperature heat storage part 18, and the inert gas source 25. The flow-channel-switching part 28 is capable of switching the inert gas flow channel system 6 to at least a state in which the inert gas source 25 communicates with both the high-temperature heat storage part 17 and the low-temperature heat storage part 18, and a state in which the inert gas source 25 is cut off from both the high-temperature heat storage part 17 and the low-temperature heat storage part 18.
