Boeing Completes First Green Diesel Flight

Green diesel could be used to power aircraft in future, according to Boeing. The OEM has successfully completed a test flight of its ecoDemonstrator 787 using a blend of 15 per cent green diesel in one engine. Green diesel is made from vegetable oils, waste cooking oil and waste animal fats and is chemically similar to HEFA (hydro-processed esters and fatty acids) aviation biofuel, which was approved for use in 2011. “Green diesel offers a tremendous opportunity to make sustainable aviation biofuel more available and more affordable for our customers,” said Julie Felgar, managing director of environmental strategy and integration at Boeing.
