From a thermodynamic standpoint, sensible heat storage relies on increasing the enthalpy of the material, which is usually a liquid or solid. The result of this process is a temperature change. The amount of heat stored can be calculated using the following equation: Q = m ⋅ c⋅ ΔT. where: Q is the stored heat. m is the mass of the material.

Latent heat storage systems are often said to have higher storage densities than storage systems based on sensible heat storage. This is not generally true; for most PCMs, the phase change enthalpy Δh pc corresponds to the change in sensible heat with a temperature change between 100–200 K, so the storage density of sensible
