Having flown its hydrogen-powered Dornier 228 testbed airplane 10 times over the past six months, ZeroAvia says it has wrapped up its initial flight test campaign and is now preparing for its first cross-country flights. ZeroAvia retrofitted the 19-seat twin turboprop with a prototype of its 600-kilowatt ZA600 powertrain, which uses hydrogen fuel cells to generate electricity. 

With one of its engines replaced, the converted Dornier 228 made its first hydrogen-powered flight in January at Cotswold Airport in the UK, Over the course of the test campaign, the Dornier 228 reached altitudes of up to 5,000 feet and operated in temperatures ranging from just above freezing to 30 degrees Celsius (86 degrees Fahrenheit), according to ZeroAvia.
