The turbofan design would be capable of operating trans-continentally and would be powered by a modified gas-turbine engine running on hydrogen, rather than jet fuel, through combustion, it stated. At a press briefing, Airbus India president Remi Maillard told reporters that, "we believe that hydrogen will increasingly become more cost-competitive in the future, because other industries, and not just aviation, will move towards hydrogen power sources". The second concept is a turboprop design that can carry up to 100 passengers and is powered by hydrogen combustion in modified gas-turbine engines, the release stated. The turboprop design would be capable of travelling more than 1,000 nautical miles, making it a perfect option for short-haul trips, it mentioned. Malliard said, "Obviously, many challenges remain, namely the availability of hydrogen, decarbonisation of the production of hydrogen, and the airworthiness certification of a hydrogen powered aircraft." He said airports, for instance, will require significant hydrogen transport and refuelling infrastructure to meet the needs of day-to-day operations. "We will need to convert our oil and gas network as well to make them suitable for hydrogen," Malliard said. "So, it is the beginning of a journey and we are committed to this ambition," he said. The third concept is a "blended-wing body" design, which can carry up to 200 passengers. In this design, the wings merge with the main body of the aircraft. It will be able to operate trans-continentally, the release stated.

These three concepts for the "world's first zero-emission commercial aircraft" could enter service by 2035, it stated. "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 be a solution for aerospace and many other industries to meet their climate-neutral targets," said the release.
