Airbus introduced a groundbreaking hydrogen-powered aircraft prototype named ZEROe at its annual aviation conference in Toulouse. The aircraft features four electric engines powered by hydrogen fuel cells, generating two megawatts of power each. Despite the external appearance resembling old propeller engines, these engines operate quietly, efficiently, and without emissions. The aircraft concept includes two central liquid hydrogen tanks feeding the fuel cells, powering the aircraft with a total output of 8 megawatts. Airbus has successfully conducted tests on the propulsion system and integrated components, with plans to enter commercial service in the late 2030s. In addition to the technological advancements, Airbus is actively engaging in developing regulatory frameworks for hydrogen aviation. The company is collaborating with international aviation and standards bodies to establish the necessary infrastructure for hydrogen-powered aircraft. The new technology is set to complement existing sustainable aviation fuel solutions, with a focus on enhancing efficiency for short- and medium-range routes. Airbus' innovative approach signifies a significant step towards emission-free aviation and a sustainable future for the industry.
