In this paper, the possibility of using hydrate-salts in solar pond as phasechange heat storage material is discussed, due to its formation of gradient layer for both sensible and latent heat storage for seasonal heat storage with only 3-5 cycles year round. The solution salt particles could be used for the regeneration of heat storage capability of that phase-change materials.
