US fuel producer Gevo says its alcohol-to-jet (ATJ) SAF production can help meet rising US jet fuel demand over the next decade while also keeping a tight lid on airline fuel bills. Sustainability got only a brief mention in a recent presentation to investors on “Refueling America.” It was all about volume and price in the context of rising US jet fuel demand, falling refinery output and the urgent need to improve US energy security. US headline jet fuel demand is poised to grow steadily from 1.7 million barrels per day last year to 1.84 million b/d by 2025. That increase of 9%, or 2.3 billion gallons per year, is down to US population growth, increased prosperity and more passenger miles being flown.
