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.

Nearly 80% of solar power installed in the Netherlands in 2017 was for small systems of less than 10 kW, a large part being rooftop Solar PV. Larger systems over 500 kW accounted for just 6.9% of the total. By the end of 2018 private residential rooftop systems had an installed capacity of 2,307 MW, businesses rooftop systems 1,662 MW whilst solar parks amounted to 444 MW.
