To analyze the risk of a hydrogen fueling station, we developed a physical model of a hydrogen fueling station, which, when using, the temperature, pressure, and flow rate of the hydrogen could be simulated under normal and abnormal operating states. The physical model was validated by comparing it with the experimental results of an actual hydrogen fueling station. Using the physical model and statistical methods, we evaluated the significance of the safety measures in the case wherein multiple safety measures fail simultaneously. We determined the combinations of failures of safety measures that could lead to severe consequence of accidents and proposed a measure for preventing and mitigating the accident scenario. In particular, in the case of the safety measures for accidents arranged in series, the combination of failures of the overfill preventing valve, flow control valve (high flow rate), and isolation valve (compressor–dispenser) had the highest influence degree. If the risk due to the combination of failures of the safety measures cannot be tolerated, the safety measures should be controlled using different electrical systems.
