The study on the results of hydrogen pipeline leakage accident of different factors

Pipeline is frequently used in long-distance hydrogen transport, while pipes can be disturbed in some conditions, prone to leakage accident, causing severe combustion or explosion. This paper analyzed the influences of different factors on the consequences of hydrogen pipeline leakage through the simulation software ALOHA. The results show that wind speed, ground roughness, tube pressure and gap area have a great impact on the consequences of the accident; wind speed and ground roughness have negative correlation to danger distance; tube pressure and gap area have positive correlation to danger distance. These results are due to the release amount and release rate influenced by the four factors.
