Having met the refinery's highest quality requirements and achieved mechanical completion of the electrolysis system, Sunfire is now moving the pioneering MultiPLHY hydrogen project into its commissioning phase.
Over the past few months, Sunfire has installed twelve electrolysis modules at the refinery, which together make up the world's largest high-temperature electrolysis system (2.6 MW) installed in an industrial environment.
The system is based on Sunfire's efficient SOEC (Solid Oxide Electrolysis Cell) technology, which operates at temperatures of 850 °C. Utilising industrial excess heat, the electrolyser processes steam to hydrogen with the highest conversion efficiency. Compared to other electrolysis solutions, Sunfire's SOEC technology is the most efficient on the market because the high-temperature-process significantly reduces the amount of electricity required.
Sunfire's electrolyser will be integrated into Neste's refinery processes and will become part of the on-site production of renewable products. Once operational, the electrolyser will produce more than 60 kg of green hydrogen per hour.
“We are proud to soon demonstrate our multi-megawatt electrolyser in an industrial refinery environment” said Nils Aldag, CEO of Sunfire. “Groundbreaking hydrogen projects like MultiPLHY are laying the foundation to secure Europe's position as a global leader in clean technologies.”
In addition to Sunfire, the MultiPLHY consortium includes Neste, the French research center CEA, SMS Group company Paul Wurth and ENGIE. The project is funded by the EU Clean Hydrogen Partnership.
