A solar panel that makes hydrogen sounds simple until engineers try making it bigger. SunHydrogen has now crossed 10% solar-to-hydrogen efficiency in new Australian testing. That sounds like a clear step forward for direct solar hydrogen technology. But the company has faced a revealing problem before, when larger modules produced lower efficiency.
The latest result came from preliminary testing with Sparc Hydrogen in Australia. SunHydrogen said its modules exceeded 10% efficiency while producing more hydrogen under concentrated sunlight. The companies are now preparing for additional laboratory work and potential pilot-scale testing in South Australia.
