Boeing flies jet on ‘green diesel’

Boeing Co. has completed a flight using ‘green diesel,’ a biofuel already used in ground transportation.

Boeing said the test flight, conducted Tuesday, was the world’s first to use a biofuel made from vegetable oil and waste animal fat. The company’s ecoDemonstrator 787 was powered using a blend of 15 percent green diesel and 85 percent petroleum jet fuel.

“Green diesel offers a tremendous opportunity to make sustainable aviation biofuel more available and more affordable for our customers,” said Julie Felgar, Boeing Commercial Airplanes managing director of environmental strategy and integration.

The company hopes the fuel will be approved for commercial flights.

Capt. Mike Carriker, Boeing’s chief pilot for product development, said the airplane performed as designed with the blended fuel as well as regular jet fuel. “This is exactly what we want to see in flight tests with a new type of fuel,” he said in a news release.

Finland-based Neste Oil, which supplied the test fuel, said using green diesel can reduce carbon emissions by between 50 percent and 90 percent over time.
