1. Introduction An efficient thermal energy storage (TES), is required to bridge the supply and demand of energy for the effective utilization of renewable energies, off-peak electricity price variation and industrial waste heat for building heating applications [12], [11], [3]..
Unlike other forms of energy storage, such as batteries, CAES can be easily scaled up or down to meet varying energy demands. This makes it suitable for both small-scale applications, such as residential homes, as well as large-scale applications, such as power plants [ 16, 17 ].
Electrical energy storage (EES) alternatives for storing energy in a grid scale are typically batteries and pumped-hydro storage (PHS).
