Gulfstream Completes SAF Emissions Testing With Zero Sulfur

Gulfstream Aerospace has completed ground emissions testing of 100% neat sustainable aviation fuel (SAF) with zero sulfur on its new Gulfstream G700.

The testing, which took place at Gulfstream’s Savannah, Georgia, facility, used 100% neat SAF provided by World Energy and delivered by World Fuel Services. The testing also included the use of a 30/70 SAF blend. Gulfstream hopes the results will “inform the industry’s path in further reducing the overall climate impact of business aviation.”

“Gulfstream has a rich history of innovating for sustainable aviation, dating back to 2004 with the first ISO certification for our Savannah facility,” said Gulfstream President Mark Burns. “Our journey continues today as we work to enhance our understanding of fuel properties and their environmental characteristics, to assess business aviation’s impact on the climate, chart the path forward in decreasing that impact and lead the industry in driving its sustainable aviation goals.”

According to Gulfstream, the week-long testing recorded gaseous and particle measurements using special instrumentation from the FAA, NASA, Aerodyne Research and the Missouri University of Science and Technology (Missouri S&T).

Preliminary results indicated “minimal-to-no sulfur contamination of the fuel and a decrease in greenhouse gas production,” the company reported. Gulfstream believes these results demonstrate the potential of 100% neat SAF for improving air quality around airports and reducing the formation of condensation trails.

“We’d like to extend a big thank-you to our partners—the FAA, NASA, Aerodyne Research, Missouri S&T, Rolls-Royce, World Energy and World Fuel Services—without which none of this research could have been possible,” Burns said. “These partners are key to our ongoing success and the success of the entire industry in continuing to innovate and drive positive environmental change for business aviation.”
