Energy storage is a valuable tool for balancing the grid and integrating more renewable energy. When energy demand is low and production of renewables is high, the excess energy can be stored for later use. When demand for energy or power is high and supply is low, the stored energy can be discharged. Due to the hourly, seasonal, and locational ...

Thermal energy storage (TES) is an energy storage technology that absorbs the thermal energy by heating or cooling a storage medium, and this stored energy can be used later to produce a power source, or for heating or cooling in some applications [129,130]. TES are widely used in buildings and industrial processes.
