Hydrogen fuel will replace the Auxiliary Power Unit (APU) used in aviation

Airbus UpNext, the research and development division of Airbus, has announced the launch of a new demonstration program that aims to explore an innovative architecture for the non-propulsive power generation for aviation through the use of hydrogen fuel cells. With the aim of reducing CO2 emissions, nitrogen oxides (NOx) and noise levels, this program will replace the Auxiliary Power Unit (APU) a traditional hydrogen fuel cell system in a modified Airbus A330.

The Airbus UpNext program aims to develop and test a new aviation power generation architecture, replacing the conventional APU with a hydrogen fuel cell system. This new approach will not only provide power for non-propulsion functions such as air conditioning and on-board lighting, but will also contribute to the reduction of polluting gas emissions. By exploring hydrogen fuel cell technology, Airbus seeks to drive the transition to more sustainable aviation with a lower environmental impact.

Demonstrating in-flight hydrogen fuel cell operability

Airbus UpNext's HyPower program aims to demonstrate the operability and integration of the hydrogen fuel cell system in a real flight environment. Through tests on a modified Airbus A330, the company will seek to validate the stability and system restart in-flight, as well as exploring new design features and integration techniques in aviation. These tests will help to mature the safety and operations of future hydrogen-powered aircraft, further boosting the viability of this technology.

Essential collaboration to drive sustainable aviation

Airbus UpNext recognizes that the transition to more sustainable aviation cannot be achieved in isolation. Therefore, the company highlights the importance of collaboration with the Spanish government and external partners to make this series of tests possible. The flight test campaign will involve a modified Airbus A330 and system ground test bench, and Airbus UpNext will acquire a renewable hydrogen production unit to meet testing needs. This cooperation between different entities will be key to boosting the development of hydrogen-powered aircraft and achieving the decarbonization goals of the aviation sector.

Conclusion on the innovative program for aviation

Airbus UpNext's hydrogen fuel cell demonstration program represents a significant step towards more sustainable aviation with a lower environmental impact. By replacing the traditional APU with a hydrogen fuel cell system, the company seeks to reduce polluting gas emissions and explore new technologies to propel the aviation industry towards a more sustainable future. Collaboration with external partners and the Spanish government will be essential to the success of this initiative and to the development of hydrogen-powered aircraft.
