And now, the industry has taken a step forward, with a successful test flight of a hydrogen-electric engine, which produces no carbon emissions.
This is part of a race to decarbonize the aviation industry, which currently accounts for around 2.5% of global carbon emissions, although its overall contribution to climate is estimated to be higher, due to the other gases, water vapor and contrails it emits. Half the power came from the fuel cells, and half from the battery packs, a company representative confirmed in a post-flight press conference.
For a commercial flight, of course, the hydrogen tanks and fuel cell power generation systems would be housed on the outside of the aircraft. The company now aims to finalize configuration and submit it for certification by the end of the year.
