61876 - Research on Fire Test Method of High Pressure Hydrogen Storage Cylinders for Transportation 

ABSTRACT

As an important equipment in the entire hydrogen industry chain, high-pressure hydrogen storage cylinders for transportation have developed rapidly in recent years. The fire test is used to verify the explosion resistance of gas cylinders under specified fire conditions. Compared to steel gas cylinder, composite gas cylinder is more dangerous in the fire condition. The wound layer, as the main pressure-bearing structure of the composite hydrogen storage cylinder, is inflammable. In the case of fire, the mechanical properties of the cylinder will degrade quickly due to the high temperature. If the gas inside the cylinder cannot be discharged in time, the cylinder explosion will occur. Currently, some relevant standards or standard drafts have been drawn up by the international organizations, which are useful for formulating Chinese standard for hydrogen storage cylinders for transportation. The applicable scope of the standards was discussed in this paper, such as composite cylinder type, pressure range, working temperature and design life, etc. The fire test methods of composite gas cylinders in various standards were compared and analyzed, such as fuel selection, filling medium, thermocouple setting, gas cylinder placement, etc. Finally, combined with the actual fire test safety cases, the challenges for development of high-pressure composite hydrogen storage cylinders and compressed hydrogen storage systems in China were indicated. Some suggestions for the relevant standards drafts in China were put forward.
