Honeywell Aerospace Integrates Hydrogen-Electric Subsystems Into Functional Power Source Under EU Project NEWBORN
Why It MattersThe milestone signals progress toward viable hydrogen-electric propulsion for aviation, a step that could shape future clean-aircraft development across the European aerospace supply chain.
Honeywell Aerospace announced on September 17, 2026, that Project NEWBORN has successfully integrated individual subsystems into a functional hydrogen power source capable of generating and supplying electrical energy for an aircraft. Project NEWBORN is a consortium of 18 companies from 10 European countries, with a testing platform based at a research center near Prague that includes its own power source, working fluid distribution systems, electrical systems, a control room, safety equipment, and heat rejection systems, developed by Honeywell Aerospace to simulate a range of functions of an actual aircraft.
The next milestone will be an integrated ground demonstration of the complete propulsion system, in which the hydrogen power source and batteries will supply electricity to an electric motor driving an aircraft propeller. For that stage, the hydrogen power source system will be transferred to Gorizia, Italy, where final tests will bring together dozens of technologies developed at different locations across Europe into a single functional unit, connecting the fuel-cell power source to battery systems from Pipistrel and a megawatt-class electric propulsion system.
Miroslav Matoušek, NEWBORN Project Coordinator at Honeywell Aerospace, said the project demonstrates the ability of European industry, universities and research organizations to work together on ambitious technological visions and turn them into functioning systems. Ondřej Kotaba, Technology Fellow and NEWBORN Technical Lead at Honeywell Aerospace, said interconnected technologies spanning air supply and conditioning, hydrogen management, thermal management, electrical distribution, power electronics, control, communications and safety monitoring have been developed in parallel, and bringing these subsystems together will represent the culmination of the project. Project NEWBORN is funded by the European Union through the EU Clean Aviation Joint Undertaking and aims to build one of the world's most powerful hydrogen-electric aircraft propulsion systems of its kind.
