SunHydrogen has successfully operated its commercial-size 1.92m² hydrogen module outdoors in the US, producing hydrogen directly from sunlight and water without grid power.

Operating for the first time under real-world conditions, the company’s module combines light-harvesting and electrolysis functions into a single unit, rather than using separate photovoltaic panels and an electrolyser.

The demonstration took place in an open prototype housing facility, likely near SunHydrogen’s base in Coralville, Iowa, though the company did not confirm the exact location.
