Common questions about IðunnH2 and the Iceland eSAF Project.

The Iceland eSAF Project is a commercial-scale sustainable aviation fuel plant being developed 5 km from Keflavík International Airport in southwest Iceland. The project was founded in 2021 to make green hydrogen and e-fuel production a reality in Iceland.

Electro-Sustainable Aviation Fuel is a synthetic jet fuel made from renewable hydrogen and captured CO₂ using proven industrial chemistry. It meets the same international jet fuel specification (ASTM D7566) and works on today’s aircraft, engines, and fuelling infrastructure without modification.

Bio-SAF is made from biological feedstocks like waste cooking oils and animal fats. Supply is inherently limited because these feedstocks compete with other uses. eSAF is made from electricity, water, and CO₂, inputs that are available wherever renewable energy is low-cost. eSAF can scale further because its feedstock base is not constrained by biological supply chains.

Icelandair has signed a memorandum of understanding for up to 45,000 tonnes per year. Luxaviation Group has signed a strategic MoU for up to 10,000 tonnes per year.

Iceland offers nearly 100% renewable electricity at low cost, abundant freshwater, proven large-scale industrial infrastructure, established carbon capture capability, and a strategic location between Europe and North America. The grid is renewable by default, which eliminates the additionality challenges that complicate RFNBO certification in most other European countries.

An EU regulation (EU 2023/2405) requiring fuel suppliers at EU and EEA airports to blend increasing amounts of sustainable aviation fuel, rising from 2% in 2025 to 70% by 2050, with a specific sub-mandate for synthetic fuels like eSAF starting at 1.2% in 2030. Iceland is subject to this regulation through the EEA Agreement.

Yes. eSAF is certified under ASTM D7566. It blends at up to 50% with conventional Jet A-1 and is used on existing aircraft, engines, and fuelling infrastructure without any modification.

No. There is no successful wave of efficiency-improved, second-generation projects without the skills, capacities, and lessons learned only through building the first generation. First-of-a-kind facilities are how the industry gains the experience that makes later projects faster, less expensive, and less risky. The technology improves by being built, not by being waited for.
