Abstract:
A compressed air energy storage (CAES) system encompassing direct heating. The compressed air energy storage system includes a compressor for compressing ambient air, an air storage reservoir, and a thermal energy storage system. The air storage reservoir is adapted to store compressed air from the compressor. The thermal energy storage system is adapted to supply heat to the compressed air energy storage system such that the compressed air is heated to increase work production of the compressed air. The thermal energy storage system is heated using off-peak electricity.
