Thermal energy can be stored as sensible heat in a material by raising its temperature. The heat or energy storage can be calculated as. q = V ρ c p dt = m c p dt (1) where . q = sensible heat stored in the material (J, Btu) V = volume of substance (m 3, ft 3) ρ = density of substance (kg/m 3, lb/ft 3) m = mass of substance (kg, lb)
Sensible heat storage systems are able to store thermal energy by changing the temperature of a storage medium, through the use of materials such as water, rocks, or ceramics, among others. In these systems, temperatures and energy remain proportional, so that the more energy is put in a material, the higher its temperature .

Latent Heat Storage (LHS) A common approach to thermal energy storage is to use materials known as phase change materials (PCMs). These materials store heat when they undergo a phase change, for example, from solid to liquid, from liquid to gas or from solid to solid (change of one crystalline form into another without a physical phase change).
