Thermal energy storage is a technique that stores thermal energy by heating or cooling a storage medium so that the energy can be used later for power generation, heating and cooling systems, and other purposes. In order to balance energy demand and supply on a daily, monthly, and even seasonal basis, Thermal energy storage systems are used.
It can be observed from the figure that copper has the highest price which makes it less popular as energy storage materials even though it has high thermal conductivity and thermal capacity as seen from Fig. 3. On the other hand, iron derivatives like steel and cast iron have been in wide use due to their low cost and high thermal capacity.
