Liquid air energy storage technology uses off-peak or excess energy to compress, liquefy and store air in insulated tanks. The air is then evaporated, expanded and heated to produce power when demand is high. LAES solutions can be installed anywhere regardless of geography. [pdf]
Heat blankets, also called tank heater wraps or heating jackets, are insulated covers designed to keep storage tanks at a steady temperature. They work by evenly distributing heat across the tank’s surface, preventing heat loss and freezing. [pdf]

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]
