Everfuel and Crossbridge Energy Fredericia Inaugurate Denmark’s First Large-Scale Green Hydrogen Plant

Everfuel and Crossbridge Energy Fredericia have officially inaugurated the HySynergy plant, one of Europe’s first large-scale electrolysis facilities dedicated to producing RFNBO-certified green hydrogen. The launch also marks a significant milestone for Denmark as the country begins its first-ever export of green hydrogen, with the inaugural shipment transported by truck to Germany.

The inauguration event at the HySynergy site in Fredericia was attended by key dignitaries, including Finance Minister Nicolai Wammen, Japanese Ambassador to Denmark Hideki Uyama, Fredericia Mayor Christian Bro, and Finn Schousboe, CEO of Crossbridge Energy Fredericia. Industry leaders from across Denmark and Europe also participated, highlighting the project’s role in advancing the region’s green energy transition.

Green Hydrogen Production and Export Milestone

The HySynergy facility represents a major step toward integrating renewable hydrogen into industrial processes and energy systems. The plant’s output is based on electrolysis powered by renewable energy, producing green hydrogen that can replace fossil-derived hydrogen in heavy industry and transportation.

This project marks the first time that certified renewable hydrogen produced in Denmark has been exported to an international market. The move comes as European demand for green hydrogen continues to grow, driven by decarbonisation targets and favourable regulatory frameworks in neighbouring countries.

“HySynergy is a symbol of Denmark leading the way in Europe’s green transition. We have now shown that green hydrogen can be produced at industrial scale, delivered to industry – and exported,” said Jacob Krogsgaard, CEO and founder of Everfuel.
“For years, Denmark has talked about the potential of green hydrogen. Now we are showing that it is possible in practice, paving the way for the establishment of a real value chain and, in the coming years, a multiplication of production capacities as the hydrogen pipeline to Germany becomes available.”

Industrial Collaboration and Decarbonisation

Developed in close collaboration with Crossbridge Energy Fredericia, the HySynergy project demonstrates how green hydrogen can be integrated into existing industrial operations. The refinery currently uses approximately 35 tonnes of hydrogen per day in its fuel production processes, part of which is now being substituted with renewable hydrogen produced on-site.

“For Crossbridge Energy, the collaboration with Everfuel is an important milestone. We already use 35 tonnes of hydrogen per day in our production. That hydrogen is produced from fossil crude oil, but it can be replaced with green hydrogen, and we are already doing so in practice,” said Finn Schousboe, CEO of Crossbridge Energy.
“Unfortunately, there is currently no incentive to keep improving. We have shown that we can – now legislation must keep up with developments so we can deliver on Denmark’s major green ambitions.”

Expanding Denmark’s Hydrogen Capacity

The HySynergy project forms the foundation of Everfuel’s broader strategy to deploy over 2 GW of electrolysis capacity in Denmark by 2035. Future plans include expansions at Fredericia and the Project Frigg development at Revsing Energy Park near Vejen, which will enable direct hydrogen delivery to German industrial customers via a dedicated hydrogen pipeline expected to be operational by 2030.

Denmark’s Role in Europe’s Green Hydrogen Ecosystem

By linking production, industrial consumption, and export capacity, HySynergy strengthens Denmark’s position in the emerging European hydrogen value chain. The project supports both national climate goals and EU energy transition targets, showcasing how renewable hydrogen can be scaled to decarbonise heavy industries and transportation.
