Boeing Looks Into Green Fuel Environmental Strategy
Boeing Commercial Airplanes Environmental Strategy and Integration is researching a “green” fuel broadly called green diesel—which has half of the carbon emissions of regular fuel—in the hope of weaning commercial planes off of fossil fuels. Green diesel, which is already being produced, is a legitimate alternative to Jet-A fuel which is what is used now.
Biodiesel is typically made by chemically reacting lipids with alcohol producing fatty acid esters. Refined diesel can be produced that is chemically identical to diesel fuel. Any blending ratio can be used, and no modifications or checks are required for any diesel engine, but what is being considered is using green fuel in a half-and-half blend with Jet A fuel.
