As part of the Department of Energy sponsored Gen 3 program Brayton Energy has designed, manufactured, and tested an sCO2 receiver with the potential to reduce the cost of electricity produced by Concentrating Solar Power (CSP). The receiver test article consists of a flat panel of nickel alloy tubes containing the sCO2 fluid, a calorimeter surface used to measure the flux incident on the article, and insulation panels to protect the surrounding frame. Design point operation calls for a 540°C inlet temperature with a 730°C CO2 exit temperatures at a pressure of 250 bar. At the Brayton Solar Test Facility, the receiver can be tested at up to 65kW of heat transfer to the CO2 using the sCO2 circulator loop and heliostat field.
