H3 Dynamics has been contracted by Airbus UpNext for the supply of a customized airworthy 500 Kilowatt (0.5MW) hydrogen fuel cell as part of a demonstrator to replace the Auxiliary Power Unit (APU) on an Airbus aircraft. On conventional airliners, the APU is a supplementary engine that operates on standard jet fuel, and facilitates non-propulsive aircraft functions, including air conditioning and electrical power for onboard systems. New design features and integration techniques will contribute to maturing operational parameters and will demonstrate the stable operation of a fuel cell. The Airbus UpNext demonstrator was announced at the Paris Airshow last year. Unlike main power propulsion applications that require several megawatts of constant power and thus a significant amount of hydrogen, lower power non-propulsive solutions present a nearterm opportunity to support the decarbonization of operations both in-flight and on the ground.
This has helped H3 Dynamics create a new capability for on-board power systems able to be qualified for flight, which means many changes to core technologies for safety and performance requirements specific to aviation, in preparation for EASA certification.
These high energy-density hydrogen batteries are able to store 700Wh/kg compared to 190WH/kg offered by traditional storage means. AEROPAK G can be used to power small-to-medium sized commercial UAVs carrying high precision sensors and used to perform missions in which endurance is key. Cylinders can be refilled on the ground through an optional mobile refuelling station.
