The German Aerospace Centre (DLR) has recently launched the BALIS facility in Empfingen, Germany, dedicated to advancing hydrogen fuel cell technology. Collaborating with AVL, the facility specializes in the analysis and testing of various components critical to the development of emission-free propulsion systems, including fuel cell systems, electric motors, and refuelling infrastructure. Moreover, DLR is embarking on the creation of a groundbreaking megawatt-class electric propulsion system, encompassing key elements such as fuel cell assemblies, hydrogen tanks, electric motors, and control components. With a strong emphasis on research, the facility is exploring the safe handling of liquid hydrogen in large quantities to optimize fuel cell system operations. The inauguration of the test tank and refuelling infrastructure, funded by DLR with approximately €3m, signifies a significant commitment to hydrogen technology. Notably, the BALIS test center has already reached full capacity for the next three years, engaging in research projects and collaborations with various enterprises, especially in the aviation sector. The collaboration with start-ups and established companies like H2FLY, PowerCell, GE Aerospace, and Deutsche Aircraft underscores DLR's dedication to driving innovation in sustainable aviation. With a positive sentiment towards hydrogen technology, stakeholders like Karsten Lemmer and Hartmut Höppner express optimism about the prospects of achieving climate neutrality by 2045 through the development of emission-free propulsion systems for various modes of transport.
