A wide variety of materials have been studied for heat storage through the phase change effect. Paraffin wax is perhaps one of the most commonly studied, thanks to its phase change occuring in a useful temperature range. However, its low thermal conductivity limits the rate at which energy can be exchanged, hampering performance.
Heat can be applied to a phase-change material, melting it and thus storing energy within it as latent heat. Excess electrical energy, such as from renewable sources, can readily be stored in such phase change materials, as it’s possible to turn electrical energy into heat quite efficiently. The reverse is not so easy, however.
