There are three lessons to take away from Airbus’ admission that it is delaying its hydrogen-fueled aircraft dream.

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.
