Airbus UpNext launches program to explore a hydrogen-powered APU model

Airbus UpNext has launched a new demonstration program to explore, on the ground and in flight, a new architecture for non-propulsive power generation through the use of hydrogen fuel cells. In conventional airplanes, the APU (Auxiliary Power Unit), a small additional engine that runs on traditional aviation fuel, provides, together with the engines, the energy necessary to power a series of non-propulsive functions of the aircraft, such as air conditioning, on-board lighting, and electric power for avionics. With this new technology demonstrator conducted from its facilities in Spain, Airbus UpNext will replace the current APU of an A330 with a hydrogen fuel cell system that will generate electricity. Known as HyPower, the hydrogen fuel cell demonstrator also aims to reduce CO2 emissions, nitrogen oxides (NOx), and noise levels associated with a traditional APU. New design features and integration techniques will also help to mature the safety and operations of future hydrogen-powered aircraft and demonstrate the stable operation of a fuel cell in flight, including its restart. “These tests will mark a new stage in our journey to decarbonization and the ZEROe program through an ambitious flight demonstration that will take to the air by the end of 2025”, said Michael Augello, CEO of Airbus UpNext. – https://aeroin.net/airbus-upnext-lanca-programa-para-explorar-um-modelo-de-apu-movida-a-hidrogenio/
