The certification confirms that Everfuel’s production volumes meet environmental and traceability criteria under the EU’s Renewable Energy Directives (RED II and RED III).

The energy firm can now supply certified hydrogen in Denmark, Germany and northern Europe, putting Everfuel ahead of numerous European peers as demand for certified hydrogen ramps up. From 2026, RFNBO quotas for industry and transport kick in.

Under the RFNBO rules, designed to ensure only green electricity is used in production, electrolyser operators must source power from new renewable energy assets located in the same grid region and match operation on an hourly basis from 2028.

RED III mandates that 42% of industrial hydrogen be renewable by 2030, rising to 60% by 2035, with transport required to source at least 1% RFNBO hydrogen.

“RFNBO certification not only validates our ambition of producing green hydrogen at scale — it also opens the door to long-term partnerships in industry and transport,” highlighted Jacob Krogsgaard, Everfuel CEO and Founder.

Financed by Hy24, HySynergy is a collaboration project between Everfuel and Crossbridge Energy, with Danish district heating operator TVIS as a surplus heat offtaker. The green hydrogen produced reportedly offers a 99% reduction in CO2 emissions.

At full capacity, the facility can produce around eight tonnes of green hydrogen per day. A planned second phase is expected to add 100MW subphases, raising total capacity to 300MW by 2025, with phase three set to scale the site further to 1GW by 2030.

Last February, the first volumes of hydrogen produced at HySynergy were delivered to Crossbridge’s adjacent Fredericia refinery.

The certification success comes as the EU is threatening to take legal action against member states that have failed to transpose various EU directives, such as RED III, into national laws.

As of July 2025, Denmark was the only EU member state to fully transpose RED III, while others, including Germany, have made progress.
