Liquid air energy storage (LAES) – applies electricity to cool air until the air liquifies, which is then stored in a tank until peak periods when it is used to turn a turbine and generate electricity. The primary disadvantage is energy loss via heat during compression, leading to low efficiencies (Vecchi et al. 2021).
