Abstract
Unexpected hazards often arise from hydrogen storage and distribution facilities, and latent dangers induced by handling of hydrogen. This paper represents the results of CFD (computational fluid dynamics) modeling of hydrogen releases and dispersion at model storage facilities with simple geometries. Numerical results for model storage facility were compared with the reported data on the hydrogen dispersion. In addition, the hydrogen concentration in a real industrial environment, such as in the hydrogen energy station (HES), was estimated with 3D CFD modeling. The risk assessment was achieved under hypothetical hydrogen leakage scenarios.
