“Liquid Air” Energy Storage Could Save The Day for Offshore Wind Industry

Highview’s liquid air battery literally uses liquid air as a storage medium. The system deploys electricity to supercool ambient air down to -196 C, at which point it becomes compressed as a liquid. There it stays in a cryogenic state until electricity is needed, when heat is applied to restore the liquid to a gas, which is goes through a turbine to generate clean kilowatts.
