SunHydrogen modules exceed 10% solar-to-hydrogen efficiency in Sparc Hydrogen testing

HYSR•2026-08-11

Pilot-scale and commercial study milestones

Work targets integration into Sparc’s concentrated-sunlight reactor, and milestones could lead to on-sun trials at the SHARP pilot site in South Australia.

Results will feed a jointly funded levelized cost of hydrogen study to assess commercial viability.

Sparc gets concentrated-light application rights above an agreed threshold, while SunHydrogen retains rights for single-sun, decentralized production.

Solar-to-hydrogen efficiency exceeds 10% in Sparc testing

SunHydrogen entered a 24-month collaboration with Sparc Hydrogen to advance water-splitting modules from lab work to pilot-scale testing.

Modules exceeded 10% solar-to-hydrogen efficiency in Sparc lab tests, and hydrogen output rose under concentrated sunlight.
