Funded by DOE Sunshot program. The objective of the project is to develop a Microchannel Solar Receiver, culminating in an on-sun test of a commercial-scale receiver module with a surface area of approximately 1 m2. While this project is focused on the receiver for heating supercritical CO2 (sCO2) from 550°C to 720°C with an incident flux of at least 100 W/cm2 and receiver efficiency of 90%, the technology can also be applied to molten salt receiver designs with moderate changes. As part of the project deliverables, both simulation and experimental investigations will be used to demonstrate that the receiver will have a lifetime of 12,000 cycles and can meet the DOE receiver cost goals of $150/kWt.
