Even if hydrogen vehicles offer better efficiency, technological barriers remain for short-term implementation. Hydrogen storage difficulties stem from its low density, necessitating very high pressure for storage. In addition, the weight, volume, efficiency, safety of storage as well as the cost of the hydrogen must be considered. Safety is of paramount importance for deployment of hydrogen technologies as it is flammable in a wide range of concentrations with air, more sensitive to ignition due to its low minimum ignition energy, deflagrates faster due to higher burning velocity, and is prone to deflagration-to-detonation transition. Various safety measures must be implemented in order to prevent accidental leakage and ensure inherent safety. Today, the strategy of the OEM’s prioritises the development of a single electrical drivetrain platform where the battery pack is mounted in the underbody of the vehicle. The automotive industry aims to use this same space for hydrogen storage systems, with the expectation that such conformable hydrogen storage systems will be available in the next 3-5 years. The main innovations of BAM’s specialist divisions 3.5 and 8.6 in this project are, firstly, the integration of optical fibres in the filament winding of complete pressure to gain a deeper understanding of the structural behaviour under the different hydraulic and pneumatic loading conditions, and secondly, the development of a fire test platform to test the assembly of 9 tubular vessels under the fire test requirements of GTR13. Therefore, a wind damping and splinter-protecting cage was built from protection modules specifically developed for this project. Extensive safety-related tests are to be carried out at BAM during the project period.
