NREL's Thermal Systems Group is performing research and development on components for high-temperature concentrating solar power (CSP) receivers as part of DOE's SunShot effort. DOE supports R&D of CSP technologies in order to achieve SunShot Initiative cost targets with systems that can supply solar power on demand through the use of thermal energy storage. The thermal energy from the receiver can be stored and subsequently dispatched to produce electricity via a turbine driving a generator.
