Universal Hydrogen Dash 8
U.S. startup Universal Hydrogen is developing a hydrogen fuel-cell propulsion conversion for the de Havilland Canada Dash 8-300 regional turboprop to kick-start demand for its hydrogen modules. MagniX will supply the 2-megawatt electric drive and Plug Power the fuel-cell system. Service entry is planned by 2024.

ZeroAvia ZA250
Hydrogen-electric power-train developer ZeroAvia conducted the first flight of its six-seat Piper 350 testbed on fuel-cell power at Cranfield, England, in September 2020. A 250-300-mi. flight from Orkney in Scotland is planned by year-end under a government-supported project.
Projects to demonstrate the viability of electric propulsion have gathered momentum over the last several months.
