As reported in and , Airbus is opening a new ZEROe development center (ZEDC) in Stade, Germany to develop hydrogen technologies.  target future zero-emission aircraft by Airbus that will use liquid hydrogen (LH₂) instead of conventional fuel, proposed to enter into service by 2035. The ZEDC in Stade will focus on cost-effective lightweight hydrogen systems using fiber-reinforced composite materials, such as cryogenic LH₂ tanks.

“This ZEDC will benefit from the broader ecosystem of composite materials research and development such as the Airbus subsidiary Composite Technology Center and the CFK NORD research center in Stade, as well as further synergies from space and maritime activities,” Airbus CTO Sabine Klauke says. Stade is also the site for production of Airbus’ composites-intensive vertical tail planes (VTP).

The team in Stade will cooperate with ZEDC working on metal tanks, especially those in Bremen, Germany, and Nantes, France. The work will include part design and manufacturing, as well as testing assembly methods. It will also contribute to the work at other ZEDC including in Madrid, Spain, and Filton, U.K.

Aviation Week notes that under the , the technology readiness level (TRL) for a metal LH₂ tank was brought to TRL 4, while usually TRL 6 is required before launch of a product development. One of the STOHYC program’s partners, , is a specialist in conventional metal tanks and sees lighter weight composites as an option for the longer term. This view has also been expressed by hydrogen aircraft propulsion pioneer ZeroAvia. Airbus has in fact invested in ZeroAvia and agreed to collaborate on certification approaches for H₂ power systems. The companies announced they would work on a number of critical technical areas, including H₂ fuel storage, flight and ground testing of fuel cell propulsion systems, and development of H₂ refueling infrastructure and operations.

Airliners.de adds that the ZEDC in Stade is supported by the German state of Lower Saxony and also through German funded projects like the LuFo aviation research program. It will also be linked to the government’s planned hydrogen innovation and technology center in northern Germany.
