Hydrogen-powered aircraft set a new record (2 photos)


German aerospace company H2FLYStuttgart has set a new world record for its four-seat HY4 aircraft, which on April 13 became the first hydrogen-fueled passenger aircraft to reach a height of more than 2 km. In addition, the twin-body HY4 made the first hydrogen-powered flight from one major airport to another, covering the 124 km from Stuttgart to Friedrichshafen on 12 April.

The HY4 is a hybrid vehicle that runs on low-temperature hydrogen fuel cells developed by the DLR Institute of Engineering Thermodynamics in collaboration with Hydrogenics.


Hydrogen is stored under pressure to reduce weightin two carbon composite tanks, one in each fuselage. They are fed into the fuel cell, and lithium-ion batteries provide fuel at times of peak load of the 80-kilowatt electric motor. The cruising speed of the aircraft is 145 km/h, and the predicted flight range is up to 1,500 km with a minimum payload and optimal flight conditions.
