Abstract
A hybrid compressed air energy storage system is provided. A heat exchangerextracts thermal energy from a compressed air to generate a cooled compressed air stored in an air storage reservoir, e.g., a cavern. A heat exchangertransfers thermal energy generated by a carbon-neutral thermal energy sourceto cooled compressed air conveyed from reservoirto generate a heated compressed air. An expanderis solely responsive to the heated compressed air by heat exchangerto produce power and generate an expanded air. Expanderis effective to reduce a temperature of the expanded air by expander, and thus a transfer of thermal energy from an expanded exhaust gas received by a recuperator(used to heat the expanded air by the first expander) is effective for reducing waste of thermal energy in exhaust gas cooled by recuperator
