However, hydrogen gas is prone to leakage, diffusion, and explosion due to its hazardous properties, which can lead to severe safety incidents such as explosions and poisoning during storage, compression, and transportation. This paper, set against the backdrop of hydrogen refueling stations, employs the SIMPLE algorithm and Python programming to investigate the characteristics and patterns of high-pressure hydrogen leakage and diffusion. The study completes numerical simulations of hydrogen leakage and diffusion under eight scenarios, including different release source positions and nearby obstacle sizes, at atmospheric, sub-critical, and supercritical high pressures, analyzing the diffusion patterns. The research findings indicate that factors such as pressure, release source location, and the height of nearby obstacles significantly affect the leakage and diffusion of hydrogen gas. The findings of this study hold significant implications for the storage of high-pressure hydrogen and the early warning of leakage and diffusion.
