ReadiJet analysis: emissions cut in half, fuel consumption lower

By Applied Research Associates | January 08, 2013

Results from the world’s first flight powered by 100 percent biofuel that met petroleum fuel specifications without blending were released today by the National Research Council of Canada. Test results show that ReadiJet, produced by ARA and Chevron Lummus Global from Agrisoma’s Resonance feedstock and in partnership with the U.S. Air Force Research Laboratory, reduced emissions and provided better fuel efficiency than petroleum aviation fuel.

 Information collected in-flight on Oct. 29 and analyzed by a team of National Research Council experts revealed a 50 percent reduction in aerosol emissions when using ReadiJet biofuel compared to conventional fuel. Additional tests from the static engine show a significant reduction in particles (up to 25 percent) and in black carbon emissions (up to 49 percent) compared to conventional fuel. These tests also show comparable engine performance, but an improvement of 1.5 percent in specific fuel consumption during the steady state operations. The jet’s engines required no modification as the biofuel tested in-flight meets the specification test property limits of petroleum-based fuels.

“We are pleased with these positive results,” said John R. McDougall, president of the National Research Council of Canada. “The flight went smoothly and the data collected enables us to better understand the impact of biofuel on the environment. We will continue to work with our partners Applied Research Associates, Chevron Lummus Global, and Agrisoma Biosciences Inc. to bring this effective energy solution to market. The final product will be a sustainable option for reducing aviation emissions.”

“Partnering with NRC Canada’s outstanding team to fly the first-ever 100 percent biofuels flight with a fuel that meets petroleum specifications test property limits without blending was historic,” said Chuck Red, ARA’s biofuel program manager.  “Their exceptional data collection capabilities and detailed analysis shows that our ReadiJet, which produces much lower life-cycle green house gas emissions than petroleum, will also contribute to a cleaner environment with significantly lower aerosol, particle and black carbon emissions.”

NRC flew the first civil jet powered by 100 percent unblended biofuel on Oct. 29, achieving a milestone for the aviation industry. The Falcon 20 flew with both engines on ARA/CLG’s ReadiJet biofuel at 30,000 feet, similar to regular commercial aircraft altitude. A second aircraft, the T-33, tailed the Falcon in flight and collected emissions data.
