On May 21st, the Department of Energy SunShot Initiative announced $10M for six new R&D projects that will advance innovative concentrating solar power (CSP) technologies. The Concentrating Solar Power: Efficiently Leveraging Equilibrium Mechanisms for Engineering New Thermochemical Storage (CSP:ELEMENTS) funding program supports developing thermochemical energy storage (TCES) systems that can validate a cost of ≤ $15/kWhth and operate at temperatures ≥ 650 °C (> 1200 °F).
The Sandia-led CSP:ELEMENTS-funded project, “PROMOTES” (
The PROMOTES research team members and key participants include:
- Sandia National Laboratories: Drs. James Miller, Andrea Ambrosini, and Clifford Ho.
- Georgia Institute of Technology: Profs. Peter Loutzenhiser and Sheldon Jeter.
- King Saud University: Prof. Hany Al-Ansary.
- Arizona State University: Prof. Ellen Stechel.
The Sandia-led PROMOTES project will leverage Sandia’s deep experience and knowledge base in metal-oxide thermochemistry and solar particle receivers/reactor work currently funded by the DOE SunShot Initiative to methodically design, develop, characterize, and demonstrate a robust and innovative storage cycle based on newly developed redox-active metal oxides. Sandia and collaborators will develop, characterize, and demonstrate a first-of-its-kind 100 kWth particle-based TCES system for direct integration with combined-cycle Air Brayton power generator based on the endothermic reduction and exothermic reoxidation of our developed metal-oxide materials.
