Hydrogen refueling stations (HRSs) have been widely built in many countries to
meet the requirements of the rapidly developing hydrogen-fueled vehicle
industry. Safety distances are key parameters for HRS designs, but the codes and
standards used for determining safety distances vary in different countries. The
two main methods for determining the safety distances for HRSs are the
consequence-based method and the quantitative risk assessment (QRA)-based
method. This article reviews the two methods to show state-of-the-art research
on determining safety distances globally. This review shows that the harm
criteria in the consequence models differ greatly in the literature and the
QRA-based method is a more reasonable way to determine the HRS safety distances.
In addition, the QRA models lack reliable frequency data and uniform risk
acceptance criteria. Future standardized QRA models should be developed with
unified regulations and standards for hydrogen infrastructure.
