Airbus is forging ahead with its ZEROe hydrogen aircraft program, unveiling a redesigned concept that can accommodate up to 100 passengers on routes spanning 1,000nm. Despite a delay of up to 10 years in service entry, Airbus remains committed to the belief that hydrogen-powered aviation is achievable. The program's aims include enhancing the power density and efficiency of the hydrogen fuel-cell propulsion system. By consolidating from six 1.25MW engines to four 2.5MW units, the design has seen significant improvements. Airbus is focused on making the solution commercially viable at scale, acknowledging the importance of technological readiness and infrastructure development. Ground tests of the 1.2MW fuel cell powertrain have shown promising results, prompting a 15% reduction in weight and volume. Future plans involve exploring performance enhancements and incorporating new technologies like cryogenic superconductivity. While flight testing plans have been altered, Airbus remains dedicated to advancing hydrogen technology for aviation, aiming to optimize the propulsion system for potential higher-capacity aircraft.
