A prototype aircraft with a hydrogen-fueled powertrain successfully completed an initial 15-minute flight today at Grant County International Airport in Moses Lake, Wash., marking a significant step for zero-emission aviation.

Los Angeles-based Universal Hydrogen had the 40-passenger De Havilland Dash 8-300 turboprop converted to use hydrogen to power an electric propulsion system mounted on the plane’s right wing. The system incorporates a fuel cell built by Plug Power and a megawatt-class motor built by Everett, Wash.-based MagniX. Seattle-based AeroTEC assisted with the engineering for the conversion.

The engine on the left side was left unconverted to serve as a backup in case the hydrogen-based system encountered problems.

Universal Hydrogen and its partners worked in Moses Lake for months to get the plane — nicknamed Lightning McClean — ready for today’s first aerial tryout, conducted under the conditions of an experimental airworthiness certificate from the Federal Aviation Administration.

The flight began at 8:41 a.m. PT and reached a maximum altitude of 3,500 feet. “We were able to throttle back the fossil-fuel turbine engine to demonstrate cruise principally on hydrogen power,” test pilot Alex Kroll said in a news release. “The airplane handled beautifully, and the noise and vibrations from the fuel cell powertrain are significantly lower than from the conventional turbine engine.”

Is hydrogen the green aviation fuel of the future? An industry team led by California-based Universal Hydrogen is testing out that proposition amid the scrublands of central Washington state.

Universal Hydrogen is readying its converted De Havilland Dash 8-300 turboprop plane for initial flight tests later this year at Grant County International Airport in Moses Lake, Wash., with an assist from Washington state partners including Seattle-based AeroTEC and Everett-based MagniX.

Last week, Universal Hydrogen announced that it spun up the propeller on the plane’s MagniX-built electric motor powered completely by hydrogen fuel for the first time. This week, “Lightning McClean” is set to start ground testing in earnest.

“We’ll run the powertrain on the ground with the aircraft static … up to maximum power,” Mark Cousin, Universal Hydrogen’s chief technology officer, told me. “Once we’re happy with the behavior of the system, we will then move into taxi testing and the buildup to flight.”
