The intent of the project was to utilize existing market-ready technologies to create a modular station capable of providing hydrogen for the fueling of hydrogen fueled vehicles. The system could be transported to various locations to support education, research and demonstration activities. Relevant codes and standards are reviewed to determine regulatory limitations on the hydrogen refueling station. In the first stage the 3D mechanical CAD model with the tubing and layout structure of hydrogen refueling system will be designed and developed. In the second stage, simulation of the fluid flow in various parameters and the dispersion behavior of the leaked hydrogen gas will be investigated by using CFD software.
