Propulsion-hydrogen

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.

Cryo-compressed hydrogen; Nullforming antenna; Contrail mitigation; Condensed battery flies.

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.

GE’s small hybrid core; on-site hydrogen on demand; 3D-printing magnesium; and very-low-orbit space tracker.

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.

The company’s engineers are working on the business jet’s architecture, starting with a digital twin.

The aircraft will rival the carrying capacity of the largest civilian helicopters but with lower operating costs and a far superior noise and emissions footprint.

Airbus has launched a new technology demonstrator to mature superconducting electric propulsion for a future hydrogen-powered aircraft.

Airbus has signed an MOU with Hartsfield-Jackson Atlanta International Airport and Houston’s George Bush Intercontinental Airport.

Airbus has been working on hydrogen as a way to decarbonize aviation.

AirBaltic has signed a memorandum of understanding to collaborate with Dutch company Fokker Next Gen on design of a hydrogen-powered 120-150-seat airliner.

A hydrogen fuel-cell-powered helicopter is being eyed for zero-emission delivery of manufactured organs for human transplants.

What Bertrand Piccard’s new hydrogen-focused Climate Impulse circumnavigating enterprise could mean for Airbus’ ZEROe project.

Certification plans firm up as turbo-compressor and humidifier changes pave the way for the next flight-test phase.
