Abstract
Systems and methods are provided that store and release compressed gas, which include an accumulator for storing compressed gas, a gas compressor, a thermal storage subsystem, a plurality of secondary heater stages and a corresponding plurality of gas expander stages, and a secondary heat source. During accumulation operations, the thermal storage subsystem is configured to extract heat from the compressed gas produced by the gas compressor and supplied to the accumulator and store the extracted heat. During the expansion operations, the secondary heater stages and gas expander stages are configured to heat and expand compressed gas supplied from the accumulator and heated by the thermal storage subsystem. The secondary heater stages use heat supplied by the secondary heat source. The secondary heat source can extract heat from a green or renewable system or an industrial process located at or near the system that stores and releases compressed gas.
