Hydrogen Refueling Station HRS

Hydrogen refuelling stations are the prerequisite to make mobility based on hydrogen possible. A hydrogen refuelling station typically consists of:

• Hydrogen supply with low-pressure storage in the range up to 250 bar, either in gaseous or liquid form
• Compression range with medium and high-pressure storage up to 900 bar
• Cooling unit, as the hydrogen must be cooled down to -40 °C before it is filled into the vehicle
• Hydrogen dispenser

At several points during the refuelling process, temperature and pressure have to be monitored. In addition, an approval for explosion protection is required.
