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. Below is a simplified method to calculate expected energy output: Daily energy output (kWh) = Total installed capacity (kWp) × Peak sun shine hours (hours) × System efficiency (%) Key Variables: Peak sunshine hours: This depends on the geographical location.
