Lack of clean fuel biggest challenge for airlines
In a glimmer of progress for the daunting task of reducing air travel’s climate impact, a newly built plant in rural Georgia could begin pumping out the world’s first commercial quantities of a new type of cleaner jet fuel this month. The $200 million plant from LanzaJet Inc. will be the first to turn ethanol into a fuel compatible with jet engines.
The facility is one of many efforts around the globe attempting to crack one of the biggest problems facing greener air travel: finding and developing cleaner feedstocks that can generate enormous quantities of fuel without triggering ripple effects that end up worsening the climate and biodiversity crises.
Progress thus far has been very limited. Efforts to produce new types of cleaner fuels require hundreds of millions of dollars. But investors have remained wary with would-be plants routinely suffering lengthy delays and struggling to become operational.
“We need to scale-up by 1,000-fold,” says Hemant Mistry, director of net zero transition for the International Air Transport Association, which has pledged that the aviation industry will erase its carbon emissions by 2050, mostly by using huge quantities of cleaner jet fuel.
At its new facility dubbed
Freedom Pines Fuels, LanzaJet plans to produce 9 million gallons of sustainable aviation fuel (SAF) per year. In one sense, that’s just a tiny step forward: It would take 100 of these plants to fulfil just 1% of the ravenous appetite of the world’s commercial air carriers, which consumed 90 billion gallons of jet fuel last year.
But it provides a glimpse of one direction the clean fuel industry wants to go. Most SAF today is derived from animal fats and waste oils, which are relatively scarce. This has left aviation giants scouring the world for alternatives to meet their climate commitments. IAG SA, the parent company of British Airways, has pledged to up its SAF usage to 10% by 2030. Three years ago, British Airways
partnered with LanzaJet, investing in Freedom Pines’ construction and teaming up on a clean fuels facility in the UK, which they hope will come online by 2028. IAG hopes to consume its first SAF from the Georgia plant later this year. “Diversification matters,” says IAG’s Robinson. “That’s why alcohol-to-jet is quite attractive to us.”
L.E.K. Consulting, in a report on the SAF market last year, predicted alcoholto-jet will surpass today’s clean fuels to become the world’s biggest source of SAF by the middle of next decade.
