• Behavior of the solidification of disodium hydrogenphosphate dodecahydrate is investigated to develop long-term latent heat storage using supercooling. Supercooled thermal energy storage (Super-TES) can store thermal energy at the lower temperature than the melting point of the phase change material, which reduces heat loss from the storage system. Although supercooling degree strongly depends on the material itself and such conditions of the material as volume, there is not enough information on the supercooling phenomenon except distilled water and metals. Some thermophysical properties of the supercooled hydrate that relates to the crystallization are measured in detail. The growth rate of the crystal is shown as a function of temperature of the hydrate. In Super-TES, nucleus formation generally starts from the bottom of the storage tank and the crystal grows upward because of thermal stratification. Since the viscosity of the hydrate in the liquid phase below the melting point increases drastically, the growth rate does not perfectly agree with the behavior of most metals for which the rate is in proportion to the square of the supercooling degree.
