MTU Aero Engines in Munich, Germany, has made significant progress in the development of its Flying Fuel Cell, an electric powertrain designed for regional aircraft. The company has finalized the design, initiated fuel cell stack production, and successfully tested the eMoSys electric motor. Production is underway at MTU’s Munich facility. The 600-kilowatt powertrain project has also involved setting up testing infrastructure with hydrogen facilities. The initiative serves as the core of the HEROPS clean aviation research project, which aims to create hydrogen-driven electric powertrains for regional aircraft by 2035. The project involves several partners and is focused on demonstrating the feasibility and scalability of the technology. By working with industry partners and research institutions, MTU is paving the way for cleaner aviation solutions.
