A common approach to thermal storage is to use what is known as a phase change material (PCM), where input heat melts the material and its phase change — from solid to liquid — stores energy. When the PCM is cooled back down below its melting point, it turns back into a solid, at which point the stored energy is released as heat.

Heat Storage
Latent heat materials have a high heat and energy density, storing between 5 and 14 times more heat per unit of volume than sensible heat storage materials (Koukou et al., 2018). Most phase change materials are non-toxic, with long cycling lives and undergo small volume changes during the phase change.
