Compression of air creates heat; the air is warmer after compression. Expansion removes heat. If no extra heat is added, the air will be much colder after expansion. If the heat generated during compression can be stored and used during expansion, then the efficiency of the storage improves considerably. There are several ways in which a CAES system can deal with heat. Air storage can be , diabatic, , or near-isothermal.
[pdf] The energy storage system undertakes peak shaving tasks during the day, with a single charge and discharge capacity of 800MWh, reducing the photovoltaic curtailment rate from 12% to 3%; During the dry season in winter, it serves as a backup power source to ensure the stable operation of the Qinghai power grid, reducing the annual amount of abandoned hydropower by 150 million kWh.
[pdf] The "KLIMABONUS 522" program is a Luxembourgish government initiative that provides financial incentives for the installation of solar photovoltaic (PV) systems. The program offers a flat-rate subsidy of €500 per kilowatt-peak (kWp) of installed capacity, up to a maximum of 50 kW
