On Nov. 19, the Gulfstream G600 flew from Savannah, Georgia to Farnborough, UK. During the nearly seven hours flight, both of the business jet’s PW815GA engines were powered by 100% Hydroprocessed Esters and Fatty Acids (neat HEFA).

HEFA is a renewable “drop-in” biofuel that is chemically equivalent to diesel but is produced from vegetable oils and fats. With lower carbon, sulfur and aromatics content than diesel, the sustainable fuel produces roughly 70% lower lifecycle CO2 emissions than fossil-based jet fuel.

According to the Gulfstream, data collected from the endurance flight will help company gauge aircraft compatibility with future low-aromatic renewable fuels, particularly under cold temperatures for extended flight durations.

“For more than a decade, we have worked closely with Pratt & Whitney Canada to power a new generation of our business jets using the PW800 engine,” said Gulfstream president, Mark Burns. “The performance of the aircraft on the first transatlantic flight using 100% SAF showcases our commitment to leading the industry in sustainability innovation through new aircraft and propulsion technologies, while promoting environmentally responsible practices.”
