The Netherlands LH2 composite tank consortium is on track to validate a fully composite tank for storing liquid hydrogen in civil aircraft by 2025. The project, funded by the Dutch government, includes key players like Toray Advanced Composites and Royal NLR, aiming to revolutionize aviation with sustainable hydrogen technology. The consortium recently received the Best Poster Award at a prestigious conference in Germany, recognizing its significant progress. Comprising 14 companies in the Netherlands, the consortium is advancing various aspects of composite tank technology, including materials testing, cryogenic performance, automated manufacturing processes, tank design optimization, and sensor development. These efforts are crucial for transitioning to hydrogen power systems in aviation, offering weight savings and contributing to long-term decarbonization in the industry. Toray Advanced Composites and Royal NLR are at the forefront of material testing programs, focusing on mechanical performance, cryogenic behavior, and H2 permeability of composite materials. The goal is to provide lightweight solutions that perform well in extreme cryogenic environments, enabling the efficient use of hydrogen for aviation. GKN Fokker and Royal NLR are collaborating on designing LH2 composite tanks for different aircraft sizes. While GKN Fokker focuses on large commercial aircraft, Royal NLR is developing tanks for smaller aircraft like the Pipistrel Velis Electro. These tanks, designed as Type 5 pressure vessels without a liner, feature a double-walled construction for better thermal insulation while maintaining cryogenic temperatures. This innovative approach supports the consortium's vision of zero-emission flight and the expansion of hydrogen-powered aircraft capabilities.
