From Avweb:
"ZeroAvia's 19-seat Dornier 228 test bed aircraft has successfully completed its first flight using the company's prototype hydrogen-electric powertrain. The 10-minute test flight took place at Cotswold Airport in Gloucestershire, U.K., with the company noting that all systems performed as expected. The Dornier 228 test bed is outfitted with the stock Honeywell TPE-331 engine on its right wing and the 600-kW hydrogen-electric powertrain on its left wing."
Note that with current technology, a pressurized hydrogen tank that is about 3 ft wide, 18 in deep, and a foot thick and weighs 100 lb empty can hold hydrogen at 3600 psi that is equivalent to a whole 2 gallons of gasoline.
