Hydrogen has been used in many industrial and commercial applications with quite an exemplary safety record. Should it become more extensively used in the transport industry, it is thought that the existing safety procedures will provide only limited guidance for hydrogen­powered vehicles. However, automotive makers will have to ensure that this new technology is as safe as the conventional one and it is therefore important to understand in the early stage of development hydrogen behaviour on­board the vehicle in order to identify the acceptable risks and to control any hazardous risk. Since only a small number of these vehicles are in operation today, data available on safety aspects are quite limited.
