.... The RTS can achieve heat recovery effectiveness of 80% for a train producing 100 kg-H 2 /day with a 60 min cycle time. The RTS can take advantage of thermal energy storage to operate round-the-clock. Further, it implements waste heat recovery to capture the exothermic heat of water-splitting. If all...

...Song Yang; Bo Wang; Peter D. Lund; Jun Wang In this study, a solar-driven reduction process of nonstoichiometric cerium oxide in a fixed bed is optimized for efficient water splitting via metal-oxide-based redox cycling. Nitrogen is used as sweeping gas to scavenge oxygen from the beds during...
