Denmark has officially entered a new era of green energy with the inauguration of the HySynergy plant in Fredericia, marking the country’s first large-scale production of certified green hydrogen. Developed by Everfuel in partnership with Crossbridge Energy Fredericia, the facility represents one of Europe’s most advanced electrolysis projects — and the start of Denmark’s first export of green hydrogen, with the inaugural trailer shipment sent to Germany today.
The historic milestone was celebrated at a ceremony attended by Finance Minister Nicolai Wammen, Japanese Ambassador Hideki Uyama, Fredericia Mayor Christian Bro, Crossbridge Energy CEO Finn Schousboe, and senior figures from the Danish and European energy sectors.
Green hydrogen, produced through electrolysis powered entirely by renewable energy, is a carbon-free fuel seen as crucial for decarbonising heavy industry and transport. The HySynergy project is the first in Denmark to export RFNBO-certified hydrogen — a major proof point for both the country’s technological leadership and its ability to build a viable hydrogen economy connected to European markets.
“HySynergy shows that Denmark is not just talking about the green transition — we’re making it happen,” said Jacob Krogsgaard, CEO and founder of Everfuel. “We’ve proven that green hydrogen can be produced at industrial scale, delivered to industry, and even exported. This is the first step toward building a true hydrogen value chain in Northern Europe, one that will expand dramatically once the hydrogen pipeline to Germany comes online.”
Developed adjacent to Crossbridge Energy’s Fredericia refinery, HySynergy is already supplying green hydrogen to replace fossil-based hydrogen in refining processes. This partnership illustrates how hydrogen can be integrated into existing industrial systems, reducing carbon emissions from conventional fuel production.
“For Crossbridge Energy, working with Everfuel marks a key turning point,” said Finn Schousboe, CEO of Crossbridge Energy Fredericia. “We consume about 35 tonnes of hydrogen daily — today mostly produced from fossil sources. With HySynergy, we’ve proven that green hydrogen can take its place. Now, legislation must evolve to match this progress and ensure that companies are rewarded for advancing decarbonisation.”
The HySynergy facility is the first step in Everfuel’s long-term plan to deploy more than 2 gigawatts (GW) of electrolysis capacity in Denmark by 2035. Expansion plans include Project Frigg, a large-scale hydrogen production site at Revsing Energy Park near Vejen, which will be connected directly to Germany’s future hydrogen pipeline network by 2030.
With HySynergy, Denmark moves from ambition to action — establishing itself as a pioneer in Europe’s green hydrogen landscape and demonstrating how renewable hydrogen can connect industries, countries, and clean energy systems across borders.
