Background
Sensible and latent heat storage are currently the most efficient means of heat storage.
Sensible heat can be thermal potential energy or cold potential energy related to the ambient temperature, which is stored in a solid, liquid, or a mixture of solid and liquid, and the internal energy change in the form of sensible heat depends on the mass, specific heat, and temperature change of the material. The material for sensible heat energy storage must be selected to be temperature stable and yet not phase change at temperature extremes, and should have a high specific heat, a high density and an acceptably low vapor pressure.
Latent heat is energy that is released or absorbed by a material in the form of thermal energy when changing state or changing phase, such as when a solid changes to a liquid (melting) or when a liquid changes to a gas (vaporizing), and latent heat storage is attractive for materials that undergo large changes in their state during phase changes. The phase change energy (heat of fusion or heat of vaporization) of a material determines its heat storage capacity as a phase change material. When sufficient heat is applied, the molecular bonds of the phase change material are opened. Their bonding enables the phase change material to have superior heat capacity. In order to be suitable for latent heat storage, the material must possess high phase change heat, high density, suitable phase change temperature, low toxicity and long duty cycle at low cost, and the main advantage of the phase change energy storage material is its energy storage capacity versus temperature and versus mass.
