The , initiated to develop a game-changing fiber-reinforced thermoplastic composite liquid hydrogen (LH2) storage tank for future aviation, is reaching its conclusion. As the final stage is approached, the project team, comprised of academic and industrial partners, has shared some of their most significant innovations and results through a series of three webinars.
These webinars explore life cycle assessment (LCA) methodology with Professor Angela Daniela La Rosa from NTNU, delve into optical hydrogen sensor solutions developed by the TU Delft team and conclude with an in-depth presentation of OVERLEAF’s innovations in cryogenic-ready 3D printing and materials for the project’s inner tank, presented by partners Canoe, Aimen, the University of Girona and ICSI.
Webinar #1:
The first webinar addresses the essential methodology of LCA for evaluating the environmental impacts of products, processes and services across their entire life cycle, from raw material extraction to end of life (cradle to grave). It demonstrates how LCA supports the identification of sustainable strategies by assessing environmental benefits and trade-offs in material selection and processing.
Basic principles of LCA are introduced, supported by practical examples from OVERLEAF project activities. Lab-scale LCA is showcased as a powerful tool for the eco-design of innovative products, especially for guiding improvements in early stage technology development.
Webinar #2:
The second webinar focuses on optical sensor technologies that offer inherent safety advantages for hydrogen detection in potentially explosive environments. While hydrogen is a clean and efficient energy carrier, it becomes highly explosive at concentrations above 4% in air, posing critical safety challenges in storage systems.
The TU Delft team presents their development and application of optical hydrogen sensors within the OVERLEAF hydrogen storage tank. The webinar covers topics such as hydrogen-sensing material selection, the impact of reactive gases on sensor performance, integration with optical transducers and performance optimization. This achievement was made possible by combining advanced photonics, specialized materials and microfabrication expertise, resulting in a lightweight, highly sensitive solution for safe hydrogen detection.
Webinar #3:
The third webinar delves into the inner tank of a novel low-pressure LHâ‚‚ storage system. Featuring four expert partners, the session presents key innovations in materials, manufacturing processes and testing methodologies required for high-performance, cryogenic-resistant components.
Presenters also address the economic viability and industrial scalability of these technologies, outlining a clear pathway to commercialization. Case studies demonstrate how these advances significantly lower operational costs and enhance safety in critical applications. The session explores integration opportunities across aerospace, automotive and industrial sectors, opening new frontiers for hydrogen deployment in previously challenging environments.
