A Rotax piston aeroengine, a popular powerplant for light aircraft, has been converted to run on hydrogen by Austria-based Bosch Aviation Technology.

The installation of a fuel cell system in a flying testbed is being prepared by German startup Hyfly as it progresses development of a hydrogen-electric powertrain for light aircraft.

Airbus has given some early insights into the basics of its future narrowbody. An open-rotor engine clearly remains its favorite option.

Key collaborations have been announced by Australia’s fledgling sustainable aviation industry to advance development of electric- and hydrogen-powered aircraft.

ZeroAvia and Reliable Robotics are studying the integration of hydrogen-electric propulsion onto a Cessna with automation tech to make an uncrewed aircraft.

During a two-day “Airbus Summit” held in Toulouse, the manufacturer unveiled initial concepts of what a future single-aisle aircraft could look like.

Airbus is focusing on a “realpolitik” approach to accelerating innovation into products in the nearer term.

Airbus’ decision to postpone development of a hydrogen-powered airliner may have slowed chances for adoption, but it should not impede continuing research.

The aviation industry should continue to prepare for the introduction of hydrogen-powered aircraft in the future, ACI Europe President Armando Brunini said.

Beyond Aero has unveiled major changes in the design of its One business jet, a 6- to 8-seat, 800 nm-range aircraft relying on hydrogen-electric propulsion.

Supernal eVTOL breaks cover; Climate Impulse takes shape; monitoring battery health; autonomous aerial application.

The zero-emission airliner delay leaves advancing hydrogen to startups that are focusing on retrofits and smaller aircraft.

Sustainable aviation fuel is key to achieving net-zero emissions, while hydrogen fuel takes a back seat.

Airbus says it remains committed to bringing a hydrogen-electric commercial aircraft to market.

Airbus is slowing ambitions to develop a hydrogen-fueled airliner by the mid-2030s but is expanding nearer-term plans to flight test unducted and ducted sustainable aviation fueled-engines for its next-generation single aisle.

ZeroAvia says it has reached Stage 2 of the FAA’s G-1 issue paper process to establish the certification basis for the 600-kW electric propulsion system.

The challenge was launched in November 2023 with round one awards to Cranfield Aerospace Solutions, Exeter Airport Consortium and ZeroAvia in February 2024.
