Hydrogen Aviation
The use of hydrogen, particularly hydrogen fuel cell powertrains, as a pathway to zero-emissions aviation. Hydrogen offers vastly superior energy density to lithium batteries. Indeed, there's a pathway using existing technology to building aircraft that can travel just as far as anything carrying jet fuel, for significantly reduced prices, while eliminating emissions.

The blended-wing Natilus Kona aircraft, which is now flying in quarter-scale testing in California, is set to have a zero-emissions variant thanks to a partnership with Zeroavia, which will provide a 600 kW hydrogen-electric powertrain option. -
California startup JetZero says it's working with the USAF, NASA and the FAA to get a blended-wing body jet airliner into service by 2030, promising to use an astonishing 50% less fuel, and providing a perfect platform for clean hydrogen airliners. -
H2Fly has successfully tested the ground-based cryogenic fuel filling procedure that'll power groundbreaking liquid hydrogen aircraft flights in the coming months. Liquid H2 will be an absolute game-changer, allowing clean long-distance air travel. -
Following more than 350 test flights and two demonstration races of its remotely piloted Airspeeder Mk3 eVTOL, Alauda Aeronautics has revealed the design for the first crewed racer – which boasts a top speed of 360 km/h and a range of 300 km. -
Australia's AMSL Aero has celebrated the first tethered test flight of its ultra-efficient Vertiia eVTOL aircraft. With its unique box wing formation, eight tilting propellers and five seats, it promises a 1,000 km range and speeds up to 300 km/h. -
ZeroAvia's 19-seat Dornier 228 has taken its first test flight in the UK. It's a testbed for the company's clean aviation technology, using a zero-emissions hydrogen-electric powertrain that's slated for certification and commercial flights by 2025. -
France's H3 Dynamics has presented a self-contained hydrogen propulsion pod for drones and airplanes, delivering huge range and endurance figures without heavy batteries. It mirrors the approach Airbus and others are taking with commercial airliners. -
Airbus says it's on track to have a fully operational megawatt-class electric powertrain, fueled by cryogenic liquid hydrogen, tested in flight by 2026, ahead of a full-scale zero-emissions passenger airliner it plans to put into service by 2035. -
Rolls-Royce and easyJet have edged the era of clean aviation a little closer to take-off, with the successful testing of a modern jet engine using hydrogen as fuel, and flight testing in the pipeline. -
Last April, a hydrogen-powered ZeroAvia test plane lost power and crashed during flight tests. The UK's Air Accidents Investigation Branch has now completed its investigation into the incident, and confirmed that the hydrogen system was not to blame. -
H2 Clipper says large electric airships lifted and powered by green hydrogen stand ready to transport massive cargo loads over enormous distances much faster than cargo ships, and with zero emissions. But can they overcome the obvious obstacles? -
The Celera 500L is a truly remarkable design. Otto Aviation says its odd shape delivers an astonishing 59% reduction in drag, so it can cruise as fast as a small jet while using 80% less fuel. Now, Otto and ZeroAvia are giving it a clean powertrain.
