Alongside with pumped hydroelectricity storage, compressed air energy storage (CAES) is among the few grid-scale energy storage technology with power rating of 100 s MW [6], [7]. CAES operates in such a way that electrical energy is stored in the form of compressed air confined in a natural or artificial reservoir.
Compressed air energy storage (CAES) systems offer significant potential as large-scale physical energy storage technologies. Given the increasing global emphasis on carbon reduction strategies and the rapid growth of renewable energy sources, CAES has garnered considerable attention.

Gas storage can take the form of mechanical energy storage (i.e. compressed air energy storage (CAES)) or chemical energy storage in a power-to-gas scheme, using e.g. hydrogen or synthetic methane [10]. Both approaches are typically discussed as large- or grid-scale energy storage options [11], [12].

Compressed air energy storage (CAES) is a method of compressing air when energy supply is plentiful and cheap (e.g. off-peak or high renewable) and storing it for later use. The main application for CAES is grid-scale energy storage, although storage at this scale can be less efficient compared to battery storage, due to heat losses.
