A screening analysis was performed to identify concentrating solar power (CSP) concepts
that produce hydrogen with the highest efficiency. Several CSP concepts were identified that
have the potential to be much more efficient than today’s low-temperature electrolysis
technology. They combine a central receiver or dish with either a thermochemical cycle or
high-temperature electrolyzer that operate at temperatures >600 oC. The solar-to-hydrogen
efficiencies of the best central receiver concepts exceed 20%, significantly better than the
14% value predicted for low-temperature electrolysis.
