Compressed-Air Energy Storage
Compressed-air energy storage (CAES) is a technology in which energy is stored in the form of compressed air, with the amount stored being dependent on the volume of the pressure storage vessel, the pressure at which the air is stored, and the temperature at which it is stored. A simplified, grid-connected CAES system is shown in

Ditch the Batteries: Off-Grid Compressed Air Energy Storage
Unfortunately, large-scale CAES plants are very energy inefficient. Compressing and decompressing air introduces energy losses, resulting in an electric-to-electric efficiency of only 40-52%, compared to 70-85% for pumped hydropower plants, and 70-90% for chemical batteries. The low efficiency is mainly since air heats up during

Experimental and computational analysis of packed-bed thermal energy storage tank designed for adiabatic compressed air energy storage
Adiabatic compressed air energy storage (A-CAES) systems capture the heat generated during gas compression and keep it in a thermal energy storage (TES) reservoir. During the discharge phase, the heat is transferred to the expanding air, which allows the fuel combustion process to be omitted from the operating cycle.
