Airbus has revealed the 'ZEROe,' an innovative single-aisle aircraft designed to revolutionize air transport by utilizing hydrogen power to decarbonize the aviation sector. The company conducted feasibility studies on hydrogen combustion and hydrogen fuel cells, ultimately selecting hydrogen fuel cells to power the electric propulsion system. These cells convert hydrogen into electricity with water as the sole byproduct, offering carbon-neutral flight if the hydrogen is produced using renewable sources. Despite successful testing of a fuel cell demonstrator capable of generating 1.2 megawatts, Airbus faces challenges due to the weight of the cells for aviation use and delays in the aircraft's timeline. Originally planned for 2035, the ZEROe's debut is now anticipated later in the decade, attributed to the necessity of enhancing the global hydrogen ecosystem to support hydrogen-powered flight. Airbus has initiated the Hydrogen Hubs at Airports program, collaborating with airports, airlines, industry partners, and energy providers to address hydrogen production, storage, and distribution. While the ZEROe launch may be delayed, Airbus remains open to exploring alternative decarbonized flight options. The company has developed three other hydrogen-powered aircraft designs, including Turbofan, Turboprop, and Blended-Wing Body, indicating potential future investments in these technologies.
