Compare an SHS with a solid storage material and an LHS with a PCM storage material. The thermal capacity of energy storage system is a  capacity of 600 kWh. The properties of storage media are density of the SHS medium is 2400 kg/m3 and its specific heat is 1 kJ/kg K, density of the PCM medium is 1808 kg/m3, fusion enthalpy is 212 kJ/kg, and its specific heat is 1.8 kJ/kg K. The storage medium temperature variation ΔT in the TES system is 60 K. Determine for both storage systems (a) the storage energy density and (b) the mass and volume of storage medium.
