DeHavilland to Power New-Build Dash 8 Regional Airliners With Hydrogen
Under a provisional agreement with ZeroAvia, the Canadian airframer intends to deliver hydrogen-powered versions of its twin turboprop airliner, as well as being able to retrofit existing in-service aircraft with the next five years.

De Havilland Aircraft of Canada this week announced plans to power both new-build and in-service Dash 8-400 twin turboprop regional airliners with hydrogen-electric propulsion through a partnership with ZeroAvia. Under a memorandum of understanding (MoU) signed on December 14, the airframer agreed on options to buy 50 sets of ZeroAvia's in-development 2-megawatt ZA2000 powertrain, subject to finalization of partnership terms.

Following Airbus's September 2020 announcement that it is developing designs for hydrogen-powered single-aisle airliners through its ZeroE program, DeHavilland Canada is set to become the second airframer with an active program for new- build aircraft, as opposed to just retrofits for existing models.  The announcement came a day after United Airlines said it would participate in a $35 million round of funding for ZeroAvia and reserve purchase rights for 100 of its powertrains to retrofit on regional jets such as the Bombardier CRJ550.
