A compressed air energy storage system including a gas inlet pipe, at least one air compressor stage attached to the gas inlet pipe and adapted for compression of a gas, a heat transfer system to cool the gas during or after compression, at least one absorption bed attached to the heat transfer system, at least one compressed gas reservoir having an inlet and an outlet, the compressed gas reservoir being attached at its inlet to the absorption bed, at least one preheater stage that is attached to the outlet of the compressed gas reservoir for heating a compressed gas before expansion but after storage in the compressed gas reservoir, and at least one gas expander that is attached to the preheater stage and is adapted for the expansion of the compressed gas. The disclosure further provides a method of capturing CO2 during compressed air energy storage including compressing a gas in at least one compression stage, cooling a compressed gas during or after the at least one compression stage, separating CO2 from the compressed gas using an absorption bed, storing the compressed gas in a compressed gas reservoir, expanding the compressed gas while deriving work from the gas, preheating the compressed gas prior to expansion by feeding the compressed gas through at least one heat exchanger; and recycling the heat generated during compression throughout the system.
