Green Aviation Breakthrough
Airbus and MTU Aero Engines Form Joint Venture for Hydrogen Aircraft Propulsion
Anonymous
Key Points
1
The venture targets up to 20% lower fuel consumption than the most advanced turbofan engines currently in service, which could translate into improved aircraft availability and reduced maintenance intervals.
2
Manufacturing and materials integration will involve high‑temperature alloys and composite hydrogen storage tanks, with MTU leveraging its existing engine production lines and additive manufacturing to reduce part count and weight, while Airbus uses its fuel‑cell fabrication facilities with precision fuel‑cell stack assembly lines and automated hydrogen handling systems.
3
The initiative is expected to generate high‑value jobs and stimulate regional economies as Europe positions itself to lead in clean‑tech aerospace.
4
A structured, three‑step roadmap has been outlined since the Paris Air Show 2025, with a non‑binding agreement and operations planned to begin in 2027, indicating a staged path toward certification and commercialization.
5
Regulatory and policy context is shaping adoption, including EU SAF mandates under the ReFuel Aviation framework (10% SAF by 2030 rising to 70% by 2050), illustrating near‑term constraints on hydrogen propulsion.
Airbus and MTU Aero Engines have announced plans to form a joint venture to build a hydrogen fuel cell electric aircraft engine, with operations set to begin in 2027. Gasworld reported the deal follows a memorandum of understanding signed in 2025 and is still subject to regulatory approval.
The venture targets engines that burn up to 20% less fuel than the best turbofan engines flying today. Renewable Energy Magazine noted the system would be fully electric, powered by hydrogen fuel cells rather than combustion — a significant departure from how aircraft engines have worked for decades.
A €1 Billion Bet on Hydrogen Propulsion
The two companies plan to invest roughly €1 billion over five years in research and development, according to Aktiensensor. Airbus brings its fuel-cell fabrication and airframe know-how. MTU contributes engine design, certification experience, and its existing production lines. Together, they aim to cover the full lifecycle — from design to maintenance.
MTU will use additive manufacturing, a process where parts are built layer by layer, to cut part count and reduce weight. Airbus will run precision fuel-cell stack assembly lines with automated hydrogen handling systems. The goal is lower maintenance costs and better aircraft availability — meaning fewer days on the ground.
Three-Step Roadmap Launched at Paris Air Show 2025
Aerospace Global News reported that the partners outlined a structured, three-step path toward certification and commercial use. The process began with a non-binding letter of intent at the Paris Air Show in 2025. Full joint venture operations are planned for 2027. Certification and commercialization would follow in later stages.
The European Aviation Safety Agency will be involved to build clear certification pathways for hydrogen propulsion. This kind of regulatory groundwork is rare at such an early stage. It signals both companies are serious about bringing this technology to market — not just the lab.
Hydrogen Faces Real-World Hurdles From Fuel Mandates to Storage
Hydrogen propulsion faces near-term constraints. The EU's ReFuel Aviation rules require airlines to use 10% sustainable aviation fuel, known as SAF, by 2030, rising to 70% by 2050. SAF — made from waste or synthetic sources — is already available. Liquid hydrogen infrastructure at airports barely exists yet.
Hydrogen must be stored at extremely low temperatures, around minus 253 degrees Celsius, in special composite tanks. Industry observers note that building this infrastructure across global airports will take years and enormous investment. SAF remains the more practical near-term solution for most airlines, creating direct competition for adoption.
Europe Aims to Lock In Clean-Tech Aerospace Leadership
The venture fits squarely into Europe's broader ZEROe ambition — Airbus's program to bring a zero-emission commercial aircraft to market by 2035. Renewable Energy Magazine noted the partnership is designed to give Europe strategic sovereignty in next-generation aviation. In plain terms, Europe wants to own this technology before others do.
The project is also expected to create high-value engineering and manufacturing jobs across European regions. For MTU and Airbus, the stakes go beyond climate goals. Whoever certifies a working hydrogen engine first could set the global standard — and capture a market that will define commercial aviation for the next 50 years.
