Abstract: Compressed Air Energy Storage System or Other System with Cold Storage An energy storage apparatus comprises a compressor arrangement configured to compress air or other process gas and to supply the compressed air or other process gas to a compressed gas store; an expander arrangement configured to expand the air or other process gas from the compressed gas store; a first heat transfer device associated with the expander arrangement; a thermal store including a thermal storage medium; and a second heat transfer device associated with the compressor arrangement. The first heat transfer device is configured to transfer heat to the air or other process gas which has passed through the expander arrangement from the thermal storage medium, the transfer producing a reduction in the thermal energy of the thermal storage medium in order to store cold in the thermal store. The second heat transfer device is configured to transfer heat between the thermal storage medium and the air or other process gas before the air or other process gas is stored in the compressed gas store, the transfer producing an increase of the thermal energy of the thermal storage medium. The thermal store is configured to store cold such that the temperature of the thermal storage medium in use is below ambient temperature. The thermal transfer fluid and/or the thermal storage medium may be a phase change material.
