Ice Storage System. Ice thermal storage makes use of the latent heat of fusion of water (335 kJ/kg) for storing cool energy. The storage volume is determined by the final proportion of ice to water in a fully charged tank and is typically in the range of 9.47 RTH/m 3 to 14.21 RTH/m 3, depending on the ice storage technology.

The different kinds of thermal energy storage can be divided into three separate categories: sensible heat, latent heat, and thermo-chemical heat storage. Each of these has different advantages and disadvantages that determine their applications. Sensible heat storage (SHS) is the most straightforward method.
