During the Hydrogen Technology Expo North America, held June 25-26, 2025, SunHydrogen unveiled its latest technological breakthrough: a 1.92 m² prototype solar renewable hydrogen reactor designed to operate solely on sunlight and water. The event brought together specialists from across the energy sector.
How does the solar hydrogen reactor work?
The system incorporated a single hydrogen generator module, similar in size to a photovoltaic panel. photovoltaic panel panel. Its design allowed direct production of hydrogen from water, using integrated catalysts and eliminating the need for traditional electrolyzers or grid power. The company noted that this format offered decentralized, scalable and low-cost solutions.
In addition to displaying the full-scale prototype, SunHydrogen demonstrated a 100 cm² working model powered by simulated sunlight. This presentation allowed attendees to observe the separation of water into hydrogen and oxygen safely in a controlled environment, reinforcing the technology’s potential for off-grid operation.
Solar modules in industrial configuration
According to the development team, the next phase would consist of testing closed configurations for continuous operation, before moving on to a pilot project that could integrate multiple modules with an active surface area greater than 30 m². This approach sought to validate the feasibility of solar hydrogen production. solar hydrogen production in industrial environments and mobility applications.
The renewable hydrogen obtained by this method could be applied in sectors such as fertilizer manufacturing, oil refining or fuel cell transportation. transportation with fuel cells.. With the global hydrogen market projected to exceed $1 trillion per year by 2050, technologies such as SunHydrogen’s could play a key role in the transition to sustainable energy sources.
