Airbus Marks Significant Milestone in Hydrogen Propulsion System Development

In a significant step towards realizing its ambitious goal of developing a hydrogen-powered aircraft by 2035, Airbus has successfully test-run its hydrogen propulsion system, dubbed the “iron pod.” This milestone marks the first time the full system, comprising a hydrogen fuel cell, electric motors, and control and cooling equipment, has operated at full power.

Prior to this comprehensive test, Airbus had separately tested the fuel cell system and the powertrain independently, achieving power outputs of 1.2 megawatts and 1 megawatt, respectively. The recent test, however, brought together the entire system, demonstrating its seamless operation and compatibility at the targeted power level.

“This was a crucial moment for us because the architecture and design principles we validated are the same as those we envision for the final aircraft,” remarked Mathias Andriamisaina, Head of Testing and Demonstration for the ZEROe project. “Operating the complete power channel at 1.2 megawatts, the power we intend to test on our A380 demonstrator, was a resounding success.”

Airbus emphasizes that this successful integration test is a pivotal step in guiding the program’s progress. By analyzing how the individual components interact within the full system, the team can effectively refine and optimize the design, ensuring its readiness for flight testing.

“This process allows us to identify any modifications necessary to make the technology flight-worthy,” explained Hauke Peer-Lüedders, Head of Fuel Cell Propulsion System for ZEROe. “By testing the power requirements for various flight phases, including takeoff and cruising, we gain valuable insights into the system’s overall performance.”

Airbus plans to continue refining the iron pod throughout this year, with a focus on optimizing it for flight-testing conditions. Ground testing is scheduled to commence in 2025, followed by flight testing on an Airbus A380 in 2026. The ultimate goal remains to pioneer a hydrogen-powered commercial aircraft by 2035, a testament to Airbus’ commitment to sustainable aviation.
