Aviation vision fueled by hydrogen and electricity

Redmond, Wash.-based MagniX says it’s partnering with a Los Angeles startup called Universal Hydrogen to retrofit 40-passenger regional aircraft with carbon-free, hydrogen-fueled electric powertrains.

The partnership opens up a new frontier for MagniX, which is already involved in flight tests for all-electric versions of smaller airplanes such as the de Havilland Beaver (for Vancouver, B.C.-based Harbour Air) and the Cessna Grand Caravan.

This time, MagniX and Universal Hydrogen aim to transform the de Havilland Canada DHC8-Q300, better known as the Dash 8. The Dash 8 is a time-honored twin turboprop traditionally used for commercial regional air service. If the project succeeds, the lessons learned can be applied for the development of retrofit conversion kits for the wider ATR 42 family of aircraft.

Universal Hydrogen’s plan for the Dash 8 calls for MagniX to provide an electric propulsion system in the 2-megawatt class for each wing, powered by hydrogen fuel cells.

Microsoft and Toyota rev up interest in fuel-cell tech

Grid battery storage projects like Tesla’s 100-megawatt installation in Australia may be getting lots of press, but behind the scenes, hydrogen fuel-cell systems are carving out a niche in applications ranging from non-polluting motor vehicles to power-gobbling data centers.

“It’s not either-or,” said Sunita Satyapal, director of the U.S. Department of Energy’s Fuel Cell Technology Office. “We definitely need battery electric vehicles, we need advanced combustion, biofuels — really, all of the above. But what’s unique about hydrogen is its versatility.”

Satyapal and some prominent users of fuel-cell systems, including executives from Microsoft and Toyota, discussed the state of the art in Seattle today during the CleanTech Innovation Showcase, presented by CleanTech Alliance.

Fuel cells generate energy through a straightforward chemical reaction: Stored hydrogen is combined with oxygen from the air with the aid of a catalyst, producing electricity. The devices are about twice as efficient as internal combustion engineswhen it comes to converting chemical energy into power, and the only emissions they produce are air and water vapor.
