Airbus-funded powertrain developer ZeroAvia is evaluating an interim hydrogen-electric concept to power narrowbody airframes.

CAeS says it is close to securing funding to support flight-testing of a hydrogen fuel cell propulsion system on a modified Britten-Norman BN-2 Islander.

VoltAero and Kawasaki Motors have revealed new details about plans to power later versions of the Cassio hybrid-electric aircraft with a hydrogen-fueled version of its newly developed supercharged aero piston engine family.

Taking the market opportunity as a whole, EAMaven identifies a target market of 416 million travelers.

Jekta has selected ZeroAvia to develop a hydrogen-electric, fuel-cell-powered version of its PHA-ZE 100 amphibian, originally designed to rely on batteries.

Startup Dovetail Electric Aviation is testing a prototype hydrogen-electric powerplant at its facility in Seville, Spain.

London Gatwick Airport will be the site of a project to set up key infrastructure to support the future use of hydrogen as an aircraft fuel.

Collins Aerospace Ireland is leading an industry consortium to advance the concept of a conforming liquid hydrogen tank.

The facility in Chelveston, England, is planned to be operational by 2025.

Comparing hydrogen-electric propulsion startups Universal Hydrogen and ZeroAviation reveals companies with quite different business approaches.

Airbus has added more partners and a new region to its hydrogen infrastructure studies.

The same forces that led to the demise of Universal will also threaten ZeroAvia, as well as the other lesser-capitalized startups in the hydrogen space.

To simplify its fuel cell engine design, Airbus elected not to use batteries that would have boosted peak power.

Hydrogen has an unusual characteristic that could be a key to its cost-effective deployment as a zero-emission fuel for aviation.

American Airlines has signed a conditional purchase agreement with ZeroAvia for 100 hydrogen-electric engines to power regional jets.

Start-up zero-emissions propulsion developer Universal Hydrogen has been forced into liquidation after failing to raise additional funding.

Airbus is conducting a flight-test campaign to study the water vapor exhaust from a hydrogen fuel cell system to understand if it will create a contrail.

Liquid hydrogen (LH2) may be the promised panacea for aviation’s journey to net-zero, but getting there is going to be tough—particularly for the engine-makers.

Skepticism is growing about the near-term usefulness and commercial viability of the new vehicle class.

Sirius Aviation unveiled two new versions of its yet-to-be released hydrogen-electric vertical-take-off-and-landing (VTOL) aircraft, the Sirius Jet.

Sustainable aviation fuel cuts contrails; MTU progresses fuel cells; medical evacuation drone; and vertical-takeoff-and-landing cargo drone in the UAE.

The European Commission has approved up to $1.5 billion in state aid to support development and deployment of a hydrogen value chain for the transport sector.
