Aircraft manufacturing giant Boeing wants the government to approve its plan of using renewable or “green” diesel. This story from TriplePundit.com says the company is appealing to the U.S. Federal Aviation Administration (FAA) and other stakeholders to get permission to fly its planes on biodiesel’s close (but chemically different) cousin.

“Boeing wants to establish new pathways for sustainable jet fuel, and this green diesel initiative is a groundbreaking step in that long journey,” said Julie Felgar, managing director of Boeing Commercial Airplanes Environmental Strategy and Integration, in a statement. “To support our customers, industry and communities, Boeing will continue to look for opportunities to reduce aviation’s environmental footprint.”

“Green diesel approval would be a major breakthrough in the availability of competitively priced, sustainable aviation fuel,” said Dr. James Kinder, a Technical Fellow in Boeing Commercial Airplanes Propulsion Systems Division. “We are collaborating with our industry partners and the aviation community to move this innovative solution forward and reduce the industry’s reliance on fossil fuel.”

Estimates are that there’s about 600 million gallons of green diesel produced in the U.S., Europe, and Singapore, about 1 percent of jet fuel demand.

Boeing is part of the Sustainable Aviation Fuel Users Group (SAFUG), which looks to develop sustainable jet fuels. Back in 2011, Lufthansa became the first airline to test biofuels in regular flight operations.
