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 is set to produce 65,000 tonnes of SAF per year, which could cover 15% of the nation's projected jet fuel demand in 2028. The production process will involve green hydrogen generated from Iceland's renewable sources like wind, hydropower, and geothermal energy, along with biogenic carbon dioxide (CO2) from Haffner's gasification technology. Haffner's innovative approach using biochar as a by-product of biomass thermolysis will transform SAF production economics, making e-SAF projects more financially viable. This advancement is expected to facilitate airlines at Keflavík Airport in surpassing the EU SAF blending mandate by 2030. Moreover, IðunnH2 has signed a Memorandum of Understanding with Icelandair to potentially supply 45,000 tonnes of SAF starting in 2028. Nanna Baldvinsdóttir, the co-founder and CEO of IðunnH2, foresees this collaboration as a means to direct renewable energy towards Iceland's aircraft fleet, reducing emissions and lessening the nation's reliance on fuel imports.
