Small energy losses of around 0.1–0.2% of the storage tank''s total energy capacity per day enable long-duration storage for up to several weeks [8]. The system is discharged through the power recovery unit (PRU), within which liquid air is pumped from the storage tank to high pressure, evaporated, heated, and expanded to drive a generator to recover power.

Unfortunately, large-scale CAES plants are very energy inefficient. Compressing and decompressing air introduces energy losses, resulting in an electric-to-electric efficiency of only 40-52%, compared to 70-85% for pumped hydropower plants, and 70-90% for chemical batteries. The low efficiency is mainly since air heats up during …
