The project Hytazer is the first to bundle the developments of hydrogen tanks within the DLR. On the one hand, its goal is to enable a broad usage of hydrogen in various transportation systems such as aviation, space, rail, automotive and ship building. On the other hand, with liquid, compressed, cryo-compressed hydrogen and metal hydride, a broad range of hydrogen storages and energy carriers are under consideration. In the project, for selected hydrogen storage systems in the specific context of the application in a transportation system, the current state of the certification specification is reviewed and the need for tailoring, extension or the deduction of new specifications will be identified. This talk presents an overview of the project. It focusses on selected challenges in the design, manufacturing and qualification of hydrogen storages. The talk covers the definition of requirements by simulating the transportation system itself and based on existing certification criteria. Secondly simulation-based approaches for challenges such as design, sloshing and crash worthiness are presented, that will be used to show compliance against certification requirements. Next, manufacturing processes under consideration for CFRP storages with a reproducible quality and material fulfilling permeation boundary conditions are shown. Lastly a test pyramid for the qualification of liquid hydrogen storages is presented. From this, existing test setups, possible extensions and future test stands are discussed. They are used to define appropriate means of compliance for certification but also validate simulation based approaches to reduce test effort.
