Liquid Air Energy Network forms in UK; focus on transportation and energy storage

Green Car Congress

Air can be turned into a liquid by cooling it to around -196 °C using standard industrial equipment; 700 liters of ambient air becomes about 1 liter of liquid air, which can then be stored in an unpressurised insulated vessel. The Dearman Engine operates by the vaporization and expansion of cryogenic fluids.
