Solar Driven Supercritical CO2 Brayton Cycle Testing (CSP)
- Sandia National Lab. (SNL-CA), Livermore, CA (United States)
Sandia National Laboratories (SNL) provided design, modeling, and analysis to support Commonwealth Scientific and Industrial Research Organization's (CSIRO's) efforts to develop a receiver system for solarized supercritical CO2 (SCO@) Brayton cycles. A solarized sCO2 power cycle is being pursued by both the U.S. DOE and the Australian government as a means to enable renewable, dispatchable electricity with low costs and high efficiency, which will improve reliability and resiliency of both nations' energy grids. Results of this work provided annualized thermal efficiencies for an intermediate-scale falling particles receiver that can be used as the basis for a direct sCO2 receiver design that is being pursued by CSIRO. In addition, different particle-receiver configurations were analyzed to investigate large-scale designs up to ~100 MWe.
