Modeling of a Hydrogen Refueling Station for Unmanned Transport Systems

Objective. Gaseous hydrogen is one of several alternative fuels. In order to establish hydrogen as a viable alternative, it is necessary to implement hydrogen filling stations that can compete with traditional filling stations. Method. This article presents a schematic and analysis of a mobile hydrogen filling station, including for unmanned vehicle systems. Result. Based on a block diagram, a dynamic model of a direct-compression hydrogen refueling station was developed and implemented in MATLAB. Conclusion. Increasing the compressed gas pressure and the inlet hydrogen pressure can increase the hydrogen output flow. To avoid prolonged operation of the compressor unit under high load, the compressed gas pressure and the incoming hydrogen pressure must be maintained within a stable range.
