In February, Airbus caused concern by postponing its hydrogen aircraft development program, but at its annual forum, the planemaker surprised everyone by unveiling an enhanced version of its ZEROe concept. The newly proposed aircraft features four propellers, each powered by hydrogen fuel cells, representing a significant step towards sustainable aviation. While details about the aircraft itself are still scarce, it is estimated to accommodate around 100-150 passengers and resembles a larger ATR or Dash-8 model. Airbus is currently focusing on refining the power plants for the hydrogen aircraft. The challenge lies in developing lightweight yet powerful fuel cells that comply with aerospace weight and safety standards. Collaborating with ElringKlinger, Airbus has tested a system that produced 1.2 megawatts of power, and the latest design integrates a fuel cell on each motor, providing a total of two megawatts. Glenn Llewellyn, head of the ZEROe project, expressed confidence in the potential of the fully electric hydrogen propulsion concept and emphasized the need to progress storage, distribution, and propulsion systems. Airbus is also advocating for the regulatory framework essential for the deployment of hydrogen-powered commercial aircraft in the future.
