Thermal energy storage (TES) systems can store heat or cold to be used later, at different temperature, place, or power. The main use of TES is to overcome the mismatch between energy generation and energy use (Mehling and Cabeza, 2008, Dincer and Rosen, 2002, Cabeza, 2012, Alva et al., 2018).The mismatch can be in time, …
