Financed by Hy24, the facility can produce around eight tonnes of green hydrogen per day. A second phase is expected to add 100MW subphases, raising total capacity to 300MW, with phase three set to go up to 1GW by 2030.

Green hydrogen is already being supplied to the neighbouring Crossbridge Energy refinery, where it uses 35 tonnes per day to replace fossil-derived hydrogen in the production of conventional fuels.

Meanwhile, Danish district heating operator TVIS is a surplus heat offtaker.

The HySnergy plant was also certified under the EU’s Renewable Fuels of Non-Biological Origin (RFNBO) criteria in September, confirming that its production volumes meet environmental and traceability criteria under the Renewable Energy Directive.

“For years, Denmark has talked about the potential of green hydrogen,” said Jacob Krogsgaard, Everfuel CEO and Founder.

“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.”

Everfuel said the “first ever” export of Danish green hydrogen to Germany demonstrates how future cross-border hydrogen trade could function once a dedicated pipeline is in place.

Although Denmark postponed construction of the 340km hydrogen pipeline from 2028 to 2031, operator Energinet received a DKr 8bn ($1.1bn) subsidy package earlier this year to accelerate its development.

Everfuel aims to expand its electrolysis capacity to over 2GW in Denmark by 2035 through further HySynergy expansions and new projects, including Project Frigg, which will connect directly to the planned hydrogen pipeline.
