solar thermal system storage uses phase change materials for store heat
I found very good readings on molten salt. I recommend you to get a look at it
Sulaiman Al-Hashmi Heat may be stored in a solar parabolic system using a variety of materials. Water, molten salt, and phase transition materials are all typical alternatives (PCMs).
Water is a common heat storage medium because it is cheap and has a high specific heat capacity, which means it can store a lot of heat per unit of mass. Water, on the other hand, can only be utilized to store heat at low temperatures (below roughly 200°C).
Molten salt is another possibility for storing heat at greater temperatures (up to roughly 550°C). It is also reasonably priced and has a high specific heat capacity. However, it is caustic and must be handled with caution.
As they shift between solid and liquid phases, PCMs may retain and release huge quantities of heat. They have the benefit of being able to store heat at a wide range of temperatures and being generally stable, but they are costly and may not be as efficient at storing heat as other materials.
Finally, the optimal material for heat storage in a solar parabolic system will be determined by the system's individual needs, such as the desired storage temperature and the available budget.
