Airbus embraces hydrogen
Aerospace firm Airbus has begun working on zero-emission, electrical commercial passenger planes which use hydrogen as fuel, saying these could be in service as early as 2035.
Early designs revealed by Airbus indicate the planes could carry up to 200 passengers more than 2,000 miles. They would be powered by gas-turbine engines modified to burn liquid hydrogen, and through hydrogen fuel cells to create electrical power.
Airbus chief executive Guillaume Faury told the BBC the three ZEROe concept designs marked "a historic moment for the commercial aviation sector”, and that the use of hydrogen had "the potential to significantly reduce aviation's climate impact.”
However, he added, “The transition to hydrogen, as the primary power source for these concept planes, will require decisive action from the entire aviation ecosystem.”
