In a pioneering move, Gulfstream has become the first business jet manufacturer to regularly use renewable fuels, by signing a three-year contract with World Fuel Services – using agricultural waste as feedstock.
In 2011, Gulfstream collaborated with Honeywell to conduct flights using a 50/50 mix of Honeywell green jet fuel and traditional jet fuel on Gulfstream’s G450 aircraft. This testing culminated in a transatlantic flight from North America to Europe, making the G450 the first aircraft to cross the Atlantic using a 50/50 blend of renewable fuel to power one of its two engines. The feedstock for the fuel was camelina, a non-food grass crop which can be grown in rotation with food crops and actually replenishes the soil for greater yields overall.
In 2012, Gulfstream flew its fleet to the National Business Aviation Association convention in Orlando on a 50/50 blend of renewable fuels. In April 2015, Gulfstream signed a three-year contract with World Fuels for the purchase of up to 1,363,828 litres of renewable fuel per year. The fuel will be a blend of 30% renewable fuel and 70% petroleum-based Jet-A. The feedstock for the neat fuel will be from agricultural waste and demonstrates a 50% reduction in CO2 based on lifecycle emissions compared to traditional jet fuel.
This renewable fuel will be used to power the Gulfstream Airborne Product Support plane, which delivers aircraft parts to customers in North America, senior management transportation and customer demonstration flights and the flight testing of the newly-announced G500 and G600 aircraft.
Gulfstream's commitment to using renewable fuels will support the refineries that are breaking new ground by entering into this market. This project will also support the business aviation industry's goals of carbon neutral growth by 2020.
