Boeing’s new sustainability report talks a lot about improved efficiency and the use of sustainable aviation fuels (SAF), but—while Airbus is aggressively researching hydrogen fuel technologies—the Boeing report doesn’t include many details about its vision for using hydrogen as an alternative fuel.
The report stands in stark contrast to Airbus’s announcement last February—in partnership with GE Aviation and CFM International—to “flight test a direct combustion engine fueled by hydrogen in preparation for entry into service of a zero-emission aircraft by 2035.”
