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. Compressed air engines (e.g., Compressed Air Engines Concept Engines Engines'

Each of the two linear generators in the system is equipped with a mechanical spring, which is used for storing mechanical energy in the power stroke and releasing mechanical energy in the compression stroke. In an SAE paper, Huang describes a modeling and simulation study of the new free-piston linear generator.
