US firm unveils sunlight-powered hydrogen module to produce green fuel

US clean energy company SunHydrogen has unveiled its largest solar-powered hydrogen production module, measuring 20.7 square feet (1.92 square meters), marking a significant advancement toward commercial-scale renewable hydrogen generation. The module operates entirely on sunlight and water, using semiconductor materials and built-in catalysts to split water into hydrogen and oxygen without relying on traditional electrolyzers or electrical grid power. This innovation integrates solar collection and hydrogen production within a single unit designed for off-grid, distributed hydrogen generation suitable for industrial and mobility applications. The recent successful live demonstration in an open prototype housing validates the technology’s scalability and real-world potential. The company plans to next test the module in a closed system allowing continuous hydrogen and oxygen extraction with water recirculation, a critical step before scaling up to a larger pilot project at UT Austin’s Hydrogen ProtoHub featuring 16 reactors with a combined area exceeding 323 square feet (30 square meters). SunHydrogen aims to enable low-cost, local hydrogen supply anywhere with sunlight and water
