Scalable and high efficiency materials and reactors for direct solar hydrogen production

Funds research into scalable materials and reactors that split water into hydrogen directly using concentrated solar energy.

ClosedClean Hydrogen Joint UndertakingEU

For the photoelectrochemical or photocatalytic route, proposals combining separate photovoltaic panels with a standalone electrolysis unit are explicitly excluded from this topic's scope; only direct solar-to-hydrogen conversion counts. The work targets a demonstration at TRL 5, run continuously rather than in batches, with a credible scale-up strategy substantiated at 250 to 500 kilowatts for the…

This call funds research into scalable, high-efficiency materials and reactors for direct solar hydrogen production, through thermochemical cycles or photoelectrochemical/photocatalytic water splitting. Proposals should move past proof-of-concept by discovering more efficient, cost-effective catalysts and redox materials, and by demonstrating a clear scale-up strategy for reactors.
