. . . The best commercially available technologies can only reach 565 °C. The high-temperature thermal systems targeted by this program seek to achieve at least 700 °C, which would boost the efficiency and lower the cost of the electricity.
If successful, these projects will lower the cost of a CSP system by approximately $0.02 per kilowatt-hour, which is 40% of the way to the office’s 2030 cost goals of $0.05 per kilowatt-hour (kWh) for baseload CSP plants.
Through the Generation 3 CSP (Gen3 CSP) program, three teams have been selected to compete to build an integrated system that can efficiently receive solar heat and deliver it to a working fluid at greater than 700 °C temperature, while incorporating thermal energy storage. . . .
