Impacts of ambient temperature on hydrogen leakage in skid-mounted hydrogen refueling stations

Abstract This research utilizes computational modeling to examine the dispersion patterns of hydrogen leaks in skid-mounted refueling stations, considering variations in wind dynamics and thermal conditions. The findings indicate that when the wind velocity is maintained at 3 meters per second, as the temperature increases from 0°C to 20°C, the diffusion rate and range expand. However, further increasing the temperature to 40°C reduces the horizontal diffusion distance of hydrogen due to the predominant diffusion effect of nitrogen.
