Biofuels Demonstrate Flight Sustainability

Aircraft fly on 50/50 combination of biofuel with conventional jet fuel in a demonstration flight for Gulfstream Aerospace. The five aircraft flew from the company's headquarters in Savannah, Georgia to Orlando, Florida for the National Business Aviation Association (NBAA) convention with fuel supplied by Honeywell, a US technology company.

Both engines of the aircraft were powered by a 50/50 blend of Honeywell Green Jet Fuel and petroleum-derived jet fuel. The renewable fuel was made with natural oils from camelina, an inedible plant that grows in conditions where other food crops cannot.

"Honeywell Green Jet Fuel has been proven repeatedly throughout the aviation community as an alternative fuel source that not only meets strict flight specifications, but also offers significant emissions reductions," said Jim Rekoske, vice president and general manager of Honeywell's UOP renewable energy and chemicals business unit.

Each gallon on camelina-based biofuel burned reduces a plane's net carbon dioxide equivalent emissions by 68 percent. Depending on the feedstock, the fuel can offer a 65 - 85 percent reduction in greenhouse gas emissions relative to petroleum-based fuels.

When used as part of a 50 percent blend with petroleum-based jet fuel, Honeywell's biofuel is a drop-in replacement for petroleum-based jet fuel that requires no changes to aircraft technology and meets all critical specifications for flight.

Gulfstream's incorporation of Honeywell into its sustainability initiative marks the first time the fuel has been used to power the company's entire fleet.
