Airbus UpNext has launched a new demonstrator programme to explore new architecture for the generation of non-propulsive energy by hydrogen fuel cells.
Normally, the Auxiliary Power Unit (APU) is run by jet fuel, and this provides the energy required to power non-propulsive aircraft functions like air conditioning, onboard lighting, and electric power for avionics. With this technology demonstrator, Airbus will replace the APU of an A330 with a hydrogen fuel cell system that will generate electricity. This is known as HyPower, and it will reduce CO2 emissions and noise levels that come with a regular APU.
“These tests will mark a new step in our decarbonisation journey and ZEROe programme through an ambitious flight demonstration that will take to the air by end 2025,” said Michael Augello, CEO of Airbus UpNext. “We want to demonstrate the operability and integration of the system, including refuelling the aircraft with hydrogen. We will demonstrate this system in realistic conditions, climbing to 25,000ft and flying for one hour with 10kg of gaseous hydrogen on board.”
The flight test campaign will use a modified Airbus A330 and a ground test bed of the system. Airbus will procure a production unit for renewable hydrogen to fulfil the entire need for the test campaign.
