Title:
PACKED BED-BASED COMPRESSED AIR ENERGY STORAGE SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO/2022/166031
Kind Code:
A1
Abstract:
A packed bed-based compressed air energy storage system and method. The system comprises: a compression system, a gas storage system, a heat storage system, a pressure stabilizing system, and a turbine system. A low-temperature heat exchanger is provided in an air exhaust pipeline between the gas storage system and a compressor and is connected to a heat storage loop, a high-temperature heat exchanger is provided in an air exhaust pipeline between the gas storage system and the turbine system and is connected to a heat release loop, the heat storage loop converts a high-temperature high-pressure gas of the compression system into a low-temperature high-pressure gas, the gas storage system stores the low-temperature high-pressure gas, and the heat release loop converts the low-temperature high-pressure gas of the gas storage system into a high-temperature high-pressure gas to drive the turbine system to do work; a liquid heat-transfer medium circularly flows in the heat storage loop and the heat release loop as a heat-transfer medium, and completes heat storage and heat release processes together with a solid heat storage material in a packed bed heat storage apparatus. The system has the characteristics of being simple in structure, high in heat conversion efficiency, beneficial to reduce cost, safe and reliable, and easy to operate.
