Montana Renewables Fuels Gulfstream G800 High-Altitude Tests with 100% Neat SAF
CLMT•Montana Renewables LLC supplied its MaxSAF sustainable aviation fuel for Gulfstream Aerospace's G800 high-altitude testing campaign at up to 50,000-foot, showcasing potential 100% neat SAF to cut contrail-forming particles compared with conventional Jet-A. Preliminary characterization by Washington State University indicates substantial particulate emissions reduction when operating on neat HEFA-based SAF.
1. Collaboration with Gulfstream Aerospace
Montana Renewables LLC, an unrestricted subsidiary of Calumet, served as exclusive fuel supplier for Gulfstream Aerospace’s high-altitude testing campaign on the G800 business jet. The company provided MaxSAF® sustainable aviation fuel, with Washington State University conducting fuel property characterization prior to the flight tests.
2. High-Altitude Flight Test Outcomes
The campaign, which included flights up to 50,000 feet, marked the first successful demonstration of 100% neat SAF reducing contrail-forming particle emissions. Preliminary results indicate significant particulate emissions reductions compared with conventional Jet-A and low-sulfur variants, isolating fuel composition’s effect on non-CO2 emissions.
3. Strategic and Market Implications
Following these tests, Montana Renewables aims to expand SAF production to meet rising business aviation demand for low-emissions fuel. Positive test outcomes may enhance Calumet’s market position in renewable fuels and support future contracts with aerospace partners.
