Description

<p>Hydrogen can be considered as an energy carrier used to reduce CO2 emissions that affect greenhouse gases. As one of the efficient hydrogen supply forms, there is a supply system using pipelines. However, considering the spread of this system, there is a risk of accidents due to hydrogen leakage, and ensuring its safety is an important issue. Until now, there are few papers that consistently evaluate the diffusion in the ground and in the atmosphere of hydrogen when it leaks from buried pipes assuming actual operation. Therefore, it is strongly required to examine the safety risks under these conditions. In this paper, we organized the basic knowledge about the diffusion behavior of hydrogen when it leaked from the buried pipe by experiments, and presented the applicable analysis method. This knowledge is expected to be useful when examining the safety risks of system that supply hydrogen by pipelines in the future.</p>
