The energetic efficiency of pneumatic installations depends on the humidity of the compressed air. Wet compressed air requires complete drying, which consumes a lot of heat energy. By limiting the leakage of compressed air from a CART, its self-discharge is avoided, and hence the loss of energy is reduced. 8.
The energy losses for a LAES storage tank can be estimated to be around 0.1–0.2% of the tank energy capacity per day, which makes the LAES suitable as a long-term energy storage system. The effect of the storage pressure was investigated for a microgrid scale by Borri et al. [ 36 ].
Energy storage systems are increasingly gaining importance with regard to their role in achieving load levelling, especially for matching intermittent sources of renewable energy with customer demand, as well as for storing excess nuclear or thermal power during the daily cycle.
