Air-cooled heat pump energy storage

Compressed air energy storage systems: Components and

Compressed air energy storage systems may be efficient in storing unused energy, but large-scale applications have greater heat losses because the compression of air creates heat, meaning expansion is used to ensure the heat is removed [[46], [47]]. Expansion entails a change in the shape of the material due to a change in temperature.
