Fuel for the flights was produced by AltAir Paramount LLC using Honeywell UOP’s proprietary renewable jet fuel process technology, which converts non-edible animal fats and oils into renewable fuels.
The process is fully compatible with existing equipment commonly used in today’s refineries, making it easier for refiners to use existing infrastructure to produce renewable fuels.
According to Honeywell, its Green Jet Fuel can replace as much as 50% of petroleum-derived jet fuel used in flight, without any changes to the aircraft technology, while meeting the current ASTM jet fuel specifications for flight.
Depending on the bio-feedstock, Honeywell Green Jet Fuel can offer a 65 to 85% reduction in greenhouse gas emissions compared with petroleum-based fuels, it says.
United will fly on a blend of 30% renewable jet fuel and 70% petroleum jet fuel and will purchase 15 million gallons of renewable jet fuel from AltAir over a three-year period.
“United’s commitment to using renewable fuel in everyday service is a significant milestone in the adoption and use of sustainable fuels,” says Veronica May, vice president and general manager of Honeywell UOP’s Renewable Energy and Chemicals business.
“Honeywell UOP has developed a versatile portfolio of technologies that can produce renewable diesel and jet fuel, and we’ve seen a range of uses including commercial and military aircraft, bus fleets and ships.
"We remain committed to providing refiners and other producers the best technology for making renewable fuels.”
