of the first flight of an airplane with four passengers stack hydrogen were held at the airport in Stuttgart.
The powertrain of the aircraft, developed by the German Aerospace Center, is a system of storing hydrogen , a fuel cell hydrogen at low temperature and a battery.
The fuel cell directly converts hydrogen into electricity. The only waste product of this process is water. An electric motor uses the energy generated thereby to propel theaircraft .
A lithium battery high performance covers peak power loads during take off and gain altitude.
If the generated hydrogen needed for the fuel cell through electrolysis using energy from renewable energy sources the HY4 can fly without generating any emissions.
“The predictable is that large passenger aircraft will continue to fly using conventional propulsion. However, one of the biggest challenges for the coming decades is to bring electric mobility to the aviation industry and make the air transport system of future is carbon dioxide neutral “explained André Tes, Head of the DLR Institute of Engineering Thermodynamics.
