Sandia Tech Offers More Efficient Energy Storage Solution

The Falling Particle Receiver for Concentrated Solar Energy at the National Solar Thermal Test Facility is designed to lower the cost and improve the efficiencies of solar energy systems. It drops sand-like ceramic particles through a beam of concentrated sunlight focused by an array of mirrors. The receiver enables concentrated solar power with thermal storage for on-demand electricity production and process heat at significantly higher temperatures than conventional receiver technologies (up to 1000°C and higher), which can increase power cycle efficiencies and reduce levelized costs. The particle receiver is being considered for next-generation solarized supercritical CO2 Brayton cycles.
