Icelandic green hydrogen project developer IðunnH2 has partnered with Haffner Energy on the buildout of a 300MW sustainable aviation fuel (SAF) plant.

Located at Keflavík International Airport, the project is planned to produce 65,000 tonnes of SAF per year, which the partners say could meet 15% of the nation’s projected 2028 jet fuel demand.

Green hydrogen produced using Iceland’s wind, hydropower and geothermal-powered grid, will be combined with biogenic carbon dioxide (CO2), supplied from Haffner’s gasification technology.

Haffner’s technology will provide the plant with solid biochar, a by-product of biomass thermolysis, which will be gasified on-site to produce sustainable aviation fuel (SAF). According to the French firm, this process will bring about a “fundamental change” in the economics of SAF production.
