READ MOREWhat is thermal energy storage? Thermal energy storage means heating or cooling a medium to use the energy when needed later. In its simplest form, this could mean using a water tank for heat storage, where the water is heated at times when there is a lot of energy, and the energy is then stored in the water for use when energy is less plentiful.

READ MORESolar thermal energy can be stored at extremely high temperatures using molten salt. Concentrated solar power (CSP) is used to heat the salt, which melts at 131 °C, to a blistering 566 °C when it is sent to a specially insulated tank to be stored. The thermal energy can be stored here for up to a week. Whereas most sensible thermal storage
