IðunnH2, a green hydrogen project developer in Iceland, has announced a partnership with Haffner Energy to establish a 300MW sustainable aviation fuel (SAF) plant at Keflavík International Airport. The project's ambitious goal is to produce 65,000 tonnes of SAF annually, which could potentially satisfy 15% of the nation's jet fuel demand by 2028. The production process involves utilizing green hydrogen generated from Iceland's abundant wind, hydropower, and geothermal energy sources. This green hydrogen will be combined with biogenic carbon dioxide sourced from Haffner Energy's gasification technology. A key aspect of Haffner's contribution is the provision of solid biochar, a by-product of biomass thermolysis, which will undergo gasification on-site to yield sustainable aviation fuel. Haffner Energy believes that this innovative approach will lead to a significant transformation in the economics of SAF production, marking a substantial step towards sustainable aviation. The collaboration between IðunnH2 and Haffner Energy represents a pivotal moment in the renewable energy sector, showcasing the potential for eco-friendly solutions in aviation fuel production.
