air liquefaction energy storage efficiency

In this paper, a novel liquid air energy storage system with a subcooling subsystem that can replenish liquefaction capacity and ensure complete liquefaction of air inflow is proposed because of the inevitable decrease in the circulating cooling capacity during system operation.

To recover the stored energy, a highly energy-efficient pump compresses the liquid air to 100-150 bar. This pressurised liquid air is then evaporated in a heat exchange process, cooling down to approximately ambient temperature, while the very low temperature (ca. -150 oC) thermal (cold) energy is
