Airbus said on Friday it is delaying plans to develop a hydrogen-powered commercial aircraft by the middle of next decade, citing slower than expected developments in technology.

Airbus delays plans to fly a hydrogen-powered commercial aircraft by 2035, citing slower than expected advances in technology.

Airbus SE said that one of its most ambitious projects for future propulsion — using hydrogen to power an aircraft — is progressing slower than planned because of the technological hurdles involved, dealing a setback to the industry’s efforts to clean up air travel.

Airbus acknowledged on Friday that progress on developing an aeroplane operating on hydrogen was slower than expected, but said it was not reviewing its approach to decarbonising aviation. "Recent developments show that progress on indispensable elements for this transition,

TOULOUSE—Sustainable aviation fuels (SAF) and green hydrogen production is behind the curve for aviation to reach its 2050 decarbonization goals, says Sabine Klauke, chief technology officer (CTO) and EVP,
