Airbus reveals new zero-emission concept aircraft
Airbus has revealed three concepts for the world’s first zero-emission commercial aircraft, which could enter service by 2035. These concepts each represent a different approach to achieving zero-emission flight, exploring various technology pathways and aerodynamic configurations.
All of these concepts rely on hydrogen as a primary power source – an option which Airbus believes holds exceptional promise as a clean aviation fuel and is likely to play an important role in helping aerospace and many other industries meet climate neutral targets.
Guillaume Faury, chief executive officer, Airbus, said: “This is a historic moment for the commercial aviation sector as a whole and we intend to play a leading role in the most important transition this industry has ever seen. The concepts we unveil today offer the world a glimpse of our ambition to drive a bold vision for the future of zero-emission flight. I strongly believe that the use of hydrogen – both in synthetic fuels and as a primary power source for commercial aircraft – has the potential to significantly reduce aviation’s climate impact.”
The three concepts – all codenamed ZEROe – are:
• A turbofan design (120-200 passengers) with a range of 2,000+ nautical miles, capable of operating transcontinentally and powered by a modified gas turbine engine running on hydrogen, rather than jet fuel, through combustion. The liquid hydrogen will be stored and distributed via tanks located behind the rear pressure bulkhead.
• A turboprop design (up to 100 passengers) using a turboprop engine instead of a turbofan and also powered by hydrogen combustion in modified gas-turbine engines, which would be capable of travelling more than 1,000 nautical miles, making it a perfect option for short-haul trips.
• A blended-wing body design concept (up to 200 passengers) in which the wings merge with the main body of the aircraft with a range similar to that of the turbofan concept. The exceptionally wide fuselage opens up multiple options for hydrogen storage and distribution, and for cabin layout.
Faury added: “These concepts will help us explore and mature the design and layout of the world’s first climate neutral, zero-emission commercial aircraft, which we aim to put into service by 2035. The transition to hydrogen, as the primary power source for these concept planes, will require decisive action from the entire aviation ecosystem. Together, with the support from government and industrial partners, we can rise up to this challenge to scale-up renewable energy and hydrogen for the sustainable future of the aviation industry.”
According to Airbus, airports will require significant hydrogen transport and refuelling infrastructure to meet the needs of day-to-day operations. Support from governments will also be needed with increased funding for research and technology, digitalisation and mechanisms that encourage the use of sustainable fuels and the renewal of aircraft fleets to allow airlines to retire older, less environmentally friendly aircraft earlier.
