At present, there are mainly two energy storage systems suitable for large-scale energy storage applications, i.e., pumped hydro storage (PHS) and compressed air energy storage (CAES) [5], [6]. Compared with PHS, CAES is promising for the low investment costs, fast construction time and small geographic restrictions [7] .

Brayton cycle engines compress and heat air with a fuel suitable for an internal combustion engine. For example, burning natural gas or biogas heats compressed air, and then a conventional gas turbine engine or the rear portion of a jet engine expands it to produce work. Compressed air engines can recharge an electric battery. The apparently-defunct
