First Hydrogen Production – Genvia Accelerates Toward Industrial-Scale Clean Hydrogen
A Breakthrough Five Years in the Making
A major milestone has been reached: our solid-oxide electrolysis (SOEC) system in Béziers, France, is now successfully up and running. This achievement marks a decisive step toward the implementation of our solutions to decarbonize the world’s most hard-to-abate industries.
Why This Matters
Technology De-risked:
Operating clean hydrogen production in our own facilities has strengthened our confidence in both our product and our digital platform. It has been an invaluable opportunity to refine our hardware, enhance our software, and deepen our system integration expertise. The journey towards this milestone has also been the opportunity to manage complex interfaces both at various product levels and at stakeholder’s level (regulatory bodies, contractors, supplier …), driving our readiness to deploy our solutions in industrial environments. All in all, every challenge overcome has fueled our determination to scale.
Engineering Excellence:
This is far more than a system start-up. It showcases Genvia’s ability to turn cutting-edge research into high performance industrial assets. Building on more than 15 years of CEA research, our teams executed a rigorous concurrent engineering program—multiple disciplines working in parallel toward one shared goal. Hundreds of man-years, countless hours of design, manufacturing, and testing have led to this moment. The dedication, collaboration, and team spirit behind this achievement are truly remarkable. Many thanks to our team for the engagement demonstrated towards this achievement.
Performance Proven:
Our technology doesn’t just work on paper. It performs at full system scale—integrating electrolyzer modules and a complete Balance of Plant, just like an industrial installation. This milestone sends a clear signal: solid oxide electrolysis is advancing fast and is poised to become a cornerstone of clean hydrogen production. For Genvia, it validates our technological choices and unlocks the path toward our next generation product already in development.
Scaling for Impact
This milestone opens the door to the next chapters of our journey.
A key one is the deployment of our technology at ArcelorMittal’s site in Saint-Chély-d’Apcher in 2026. This installation aims both at replacing existing use of grey hydrogen as reducing agent and demonstrating the integration of Genvia SOEC solution in an industrial setup, where waste heat will fuel our electrolyzer to produce clean hydrogen.
Another major chapter is the development of our second generation product—transitioning from a demonstrator to a fully commercial solution. This new generation will integrate all our learnings and address the scalability required for major hydrogen use cases: refineries, ammonia, efuels, steel DRI, and more.
Stay tuned for more in 2026!
