Heat transfer medium in solar panels
Thermal energy storage (TES) refers to heat that is stored for later use—either to generate electricity on demand or for use in industrial processes. Concentrating solar-thermal power (CSP) plants utilize TES to increase flexibility so they can be used as “peaker” plants that supply electricity when demand is high;. TES helps address grid integration challenges related to the variability of solar energy. Storing thermal energy is less complicated and less expensive than storing electrical energy and allows CSP plants to deliver energy regardless of whether the sun is shining. SETO research for TES and HTM primarily focuses on raising the temperature of the heat that can be stored, which will ultimately lower the cost of.
