Automotive fuel cells are taking to the air, but more development is needed to make them suitable for aircraft use.

European Commission plans to incentivize investment on a large scale so hydrogen may contribute to climate goal.

Business aviation is slowly but steadily recognizing the need to adopt sustainable aviation fuel.

Despite much evidence to the opposite, the public’s image of hydrogen in aviation was set by the 1937 Hindenburg fire.

Water vapor from hydrogen-fueled aircraft will generate more contrails, but research is needed to understand persistence and mitigation.

Advanced combustors and new thermodynamic cycles are under study to exploit the energy potential of liquid hydrogen fuel.

Green aviation start-up ZeroAvia has completed the first flight of its hydrogen fuel cell-powered Piper M350 test aircraft.

Swedish startup Heart Aerospace has unveiled the electric propulsion system for its planned 19-seat regional airliner, the ES-19.

The company is making key technology choices early and still has massive challenges ahead: technological, regulatory and in convincing industry partners to participate.

An intermediate engine between the current LEAP turbofan and one that would enter service in 2035 with slashed greenhouse gas emissions is not in the cards, according to Safran CEO Philippe Petitcolin.

Drawing on government funding into hydrogen propulsion, the manufacturer is working to define a commercial airliner to enter service in 2035.

Universal Hydrogen has selected MagniX to provide the electric propulsion system for its planned conversion of the de Havilland Canada Dash 8-300 regional turboprop to hydrogen fuel-cell power.

Airbus has completed three test flights using two of its own Airbus A350s with the autopilot engaged in its Fello’fly wake vortex-riding project.

The French government has reiterated its desire to see a hydrogen-fueled Airbus flying in service by 2035, firmly reacting to those claiming the move is too risky.

France will focus on investing in hydrogen technology as part of a broader post-COVID-19 economic relaunch plan with the government planning to have a hydrogen-powered aircraft ready for 2035.

German electric aircraft start-up Lilium has partnered up with Dusseldorf and Cologne/Bonn airports to study air mobility networks in the region.

Travel Foundation CEO says severely reduced level of flying offers the industry a chance to rethink unsustainable practices.

Air France has tested all-electric ramp-handling equipment for the first time ahead of an Airbus A350 flight from Paris to Delhi as part of broader sustainability efforts, which include making its ground operations carbon neutral by 2030.

The first of two aircraft fitted with a modular hybrid-electric propulsion system developed under a European research program is expected to fly in September.

EasyJet director calls on industry to ensure governments have right policies in place.

Even as it begins deliveries of its first certified electric aircraft, Slovenia’s Pipistrel has begun accepting orders for a family of unmanned cargo aircraft.

To kick-start the market, startup Universal Hydrogen plans to convert ATR 42 and De Havilland Canada Dash 8-300 regional aircraft to hydrogen fuel-cell propulsion to pump-prime demand.

Engine-makers adjust to changing post-pandemic priorities and consider accelerating efforts on advanced and disruptive technologies.

Air BP and Neste are to offer a vastly increased amount of sustainable aviation fuel (SAF) to airport customers, the two companies said Aug. 19.

Why sustainability is not being sidelined by leading MROs because of the COVID-19 pandemic.
