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.

We've been following the development of Australia's AMSL Aero's longe-range, hydrogen-powered Vertiia eVTOL for some time and now the box-winged tilt-rotor aircraft has completed its first free flight after over a year of 50 tethered tests. -
Making a virtue out of necessity, Airbus is joining forces with Toshiba to develop a super-efficient superconducting motor for aircraft that uses the liquid hydrogen that supplies the electricity to cool the propulsion and adjacent systems. -
This unique blended-wing airliner promises not only to reduce fuel burn and emissions by an enormous 50% - but thanks to a new partnership, it could also be the best chance we've seen to deliver proper long-range, zero emissions air travel. -
As hydrogen-powered vehicles continue to evolve, their use will become as niche as that of some current land-, sea-, and air-transportation methods, such as a new agreement that will see helicopters powered by the green fuel used for organ transport. -
Swiss clean-energy aviation startup JEKTA has announced a partnership with fuel-cell powertrain developer ZeroAvia to extend the flight range and payload capacity of an upcoming electric amphibious passenger aircraft called the PHA-ZE 100. -
In a stunning validation of hydrogen's potential in aircraft, Joby Aviation has made an incredible 523-mile non-stop flight with its S4 eVTOL air taxi. That's more than triple its range on batteries, and an absolute landmark moment for clean aviation. -
Sirius Aviation, in partnership with BMW Designworks, has today offered the first look at the inside and out of its upcoming CEO Jet, a winged eVTOL with 28 ducted fans that's powered by hydrogen fuel cells for a range of 1,150 miles per trip. -
Universal Hydrogen is already flying the world's largest hydrogen airliner – and now the company has started testing swappable liquid hydrogen fuel modules that'll radically boost the range of clean passenger aircraft operations slated for 2026. -
ZeroAvia is working with San Francisco startup Verne to bring an even more energy-dense form of hydrogen to the clean aviation space. Cryo-compressed H2 could reduce costs, speed up fueling, and unlock 40% more flight range than cryogenic liquid H2. -
The Sirius Jet will fly up to 1,150 miles (1,851 km) at speeds up to 323 mph (520 km/h) on a clean liquid-hydrogen powertrain. It'll rise vertically off a pad thanks to a deflected vectored thrust system using 20 smallish electric ducted fans. -
London startup Lyte Aviation is thinking big when it comes to VTOL aircraft. Forget your piddly five-seaters, Lyte says its first aircraft will be a 44-seat monster with a 300-km/h (186-mph) top speed and a range over 1,000 km (620 miles). -
Liquid hydrogen is a giant pain to handle, but it's one of the few technologies with a genuine chance of decarbonizing long-range flight. So it's huge news for clean aviation that H2Fly has now landed the word's first piloted liquid hydrogen flight.
