Abstract:Due to the high energy-density of liquid hydrogen energy fuel, it is expected to be widely used in rail transportation. Considering that liquid hydrogen energy has potential risks in the process of refueling or transportation, a risk assessment model for rail transit hydrogen refueling stations is proposed by applying the factor interaction theory in the Fine Kinney framework for multi-level assessments. In the case analysis, a scientific assessment of the risk index of a hydrogen refueling station in Foshan is carried out to ensure its safe operation in the whole process and situation. The results show that the inherent characteristics of hydrogen energy, together with the surrounding multiple alternating vehicles and people, bring potential safety risks to rail transit hydrogen refueling stations, which should be taken seriously during the hydrogen refueling operation.
