轨道交通车辆储氢技术研究

Research on hydrogen storage technology of rail transit vehicles

随着能源危机的逐渐迫近以及环境污染的日益严重,新能源尤其是氢能源成为研究者们关注的重点。氢能源轨道交通车辆作为响应国家双碳政策的典型代表,储氢技术则直接决定了它的续航里程。文章对高压气态储氢、液态储氢、固态储氢技术的原理与特点、核心技术的发展现状及其在轨道交通车辆的适用性进行剖析与研究,分析不同储氢方式的应用优劣势并进行了前景展望。

With the approaching of energy crisis and the increasingly serious environmental pollution,new energy,especially hydrogen energy,has become the focus of researchers.Hydrogen powered rail transit vehicle is a typical representative of responding to the national dual carbon policy,and hydrogen storage technology directly determines its range.This paper analyzes and studies the principle and characteristics of high-pressure gaseous hydrogen storage,liquid hydrogen storage and solid hydrogen storage technology,the current development status of core technologies,and their applicability in rail transit vehicles.The advantages and disadvantages of different hydrogen storage methods in application are analyzed,and the prospects are discussed.
