“…Among different phase transitions, solid-liquid and solid-solid are particularly attractive since they provide high energy storage densities, something that, in turn, reduces the technological requirements of TES systems [ 8 ]. PCMs have been widely used in latent heat accumulation to improve the energy management in heat pumps [ 9 , 10 ], automotive [ 11 ], solar engineering [ 12 , 13 ], spacecraft [ 14 , 15 ] or heating, ventilation, and air conditioning facilities [ 16 , 17 , 18 , 19 ], for instance.…”
