Abstract
In order to expand the supply of hydrogen vehicles, the first thing to be done is to build an infrastructure to supply hydrogen. There are fixed and mobile types of hydrogen refueling stations that can supply hydrogen. Mobile hydrogen refueling stations have the advantage of supplying hydrogen to two or three areas, so the introduction of mobile hydrogen refueling stations is considered at the initial stage of hydrogen vehicle dissemination. However, mobile hydrogen refueling stations have greater risks than fixed hydrogen refueling stations due to the hazard associated with movement and intensive installation of facilities in vehicle, so stricter design standards to lower the risk must be applied. Therefore, in this study, basic data for establishing safety standards for mobile hydrogen refueling stations were proposed by suggesting improvements such as the location of emergency shutoff valves, the number of gas detectors etc., using HAZOP analysis.
