What RED III Demands from Every Megawatt of Green Hydrogen

Under RED III, hydrogen qualifies as a Renewable Fuel of Non-Biological Origin — and therefore counts toward Member State RFNBO sub-targets — only if it meets strict additionality, temporal correlation and geographical correlation criteria set out in the Commission’s Delegated Regulations. For the Lingen plant, that means Sunfire’s stacks must be powered by demonstrably additional renewable electricity, and the certification chain must be auditable from the wind or solar source through to the electrolysis unit. A 300 MW facility is a large compliance surface: any gap in the documentation — a missing Guarantee of Origin, a mis-timestamped metering record — risks reclassifying the output as grey hydrogen for quota purposes.

Germany’s own RED III transposition has added further procedural layers, meaning compliance directors at both Sunfire and RWE must track not only the EU Delegated Regulations but also the German national implementing measures. The infringement proceedings the Commission launched against 13 Member States in June 2026 for failures in the ReFuelEU Aviation penalty regime illustrate how quickly regulatory gaps become enforcement events — a warning equally applicable to the RFNBO certification space.

From Electrolyser Delivery to RFNBO Credit: The Certification Gap

Shipping hardware is the easy part. The harder task is threading the output through the EU’s certification system — currently administered through the CertifHy scheme and its equivalents — so that the hydrogen can be sold to off-takers who need it to satisfy ReFuelEU Aviation SAF blending mandates or industrial RED III targets. With the Lingen plant targeting 300 MW by 2027, the volumes will be significant: at a typical load factor, a 300 MW alkaline plant can produce roughly 50,000–60,000 tonnes of hydrogen per year, potentially feeding SAF or e-methanol synthesis. Each tonne must carry a traceable RFNBO certificate to have regulatory value.

Compliance and marketing directors searching for 2030–2032 procurement strategies should note that the certification bottleneck is as real as the hardware bottleneck. Industry bodies and the European Commission have acknowledged that the registry infrastructure for RFNBO certificates is still maturing, and early movers who invest in audit-ready metering and digital certification workflows will have a procurement advantage over late entrants scrambling to demonstrate additionality retrospectively.

Efficiency Objection, Policy Answer, and the Road Ahead

The standard objection to electrolytic green hydrogen — and the e-fuels derived from it — is well-founded: the well-to-wheel efficiency of an e-fuel powertrain sits at roughly 13–20%, compared with 70–80% for a battery-electric vehicle, meaning approximately five times more renewable electricity is consumed per kilometre driven. Transport & Environment and the ICCT cite this gap as the core argument against e-fuels in road passenger transport, and it is an argument compliance directors should be able to answer, not dodge. The honest answer is that green hydrogen is not primarily targeted at light passenger cars; its regulatory rationale under RED III and ReFuelEU Aviation lies in sectors batteries cannot serve — long-haul aviation, deep-sea shipping, high-temperature industrial processes and the legacy combustion fleet.

For those sectors, the Lingen plant’s trajectory to 300 MW by 2027 represents exactly the kind of supply-side scale the EU’s certification ecosystem needs to mature around. The Sunfire shipment is not merely a logistics event; it is a live trial of whether the EU’s green hydrogen policy architecture — RED III quotas, RFNBO delegated acts, Guarantees of Origin and cross-border certification — can keep pace with industrial deployment.
