Price: Although the price of the storage media is only a part of the total cost of the system, it is clear that the lower the price of the PCM the better. It should be highlighted that the price considered here was not the cost per kg of material, which is the usual purchase cost, but the cost per energy unit, so the comparison between materials

As a phase change energy storage medium, phase change material does not have any form of energy itself. It stores the excess heat in the external environment in the form of latent heat and releases the energy under appropriate conditions.
