The liquefied air is stored in the liquid air storage unit; thus, the compression energy is stored in the form of liquid air (A12). During energy release, stored liquid air is pumped to 210 bar (A13–A14), and the pressurized liquid air is gasified to natural gas through heat exchange with seawater (A14–A15).
