Aspects of safety and acceptance of LH2 tank systems in passenger cars

In the light of the current lack of safety concepts for hydrogen-drive cars, it is deemed essential to make a systematic determination and assessment of possible hazards, effective improvements of the automobiles involved and their surrounding aspects. This in turn calls thorough cooperation between the automobile industry, on ethe one hand, and suppliers, energy utilities, the gas industry, and licensing authorities, on the other. This paper presents the preliminary results of a test conducted to (1) determine the hazard potential of LH2 tanks used in road vehicles, taking into consideration the process of various parameters influencing the effects of this hazard, and (2) determine the further requirements of such vehicle tanks.
