摘要
由于液态氢能源燃料具有高能量密度优势,在轨道交通运输中有望得到广泛应用。考虑到液态氢能源在加注或运输环节具有潜在风险性,提出了轨道交通加氢站风险评估模型,在Fine Kinney框架中应用因素相互作用理论,对风险指数进行多层次评估。在案例分析中,对佛山市某加氢站的风险指数进行科学评估,确保加氢站全过程全态势的运行安全。结果表明:氢能不稳定特性与周边较为频繁流动车辆和人员,给轨道交通加氢站带来一定的安全风险,在加氢站运营过程中应高度关注。
Because liquid hydrogen energy fuel features high energy density,it will be widely used in railway transportation.However,liquid hydrogen energy has potential high risks during refueling or transportation.Therefore,a multi-level risk assessment model for rail transit hydrogen refueling stations was proposed by applying the factor interaction theory in the Fine Kinney framework.In a case analysis,a scientific assessment of the risk index of a hydrogen refueling station in Foshan City was carried out,to ensure safe operation in all processes and various cases.Results show that the high explosive characteristics of hydrogen energy bring highly potential safety risks to the hydrogen refueling stations of rail transit because of the busy vehicles and people nearby,which should be taken seriously during the hydrogen refueling operation.
