Refueling hydrogen is basically quite simple and works similarly at all hydrogen refueling stations throughout Europe. This is how the refueling process works in general:1. Authorization:
First, you must authorize yourself at the hydrogen refueling station. Authorization can be done via authorization media like fuel cards, apps, girocards or credit cards. Information on which authorization method is available at a selected station can be found in the station profile on H2.LIVE or by contacting the respective station operator.
Depending on the configuration of your authorization medium, you may be asked to enter a PIN code, the current mileage or the license plate number of your vehicle as part of the authorization process.2. Withdrawal the fuel nozzle:
After you have successfully authorized yourself at the hydrogen refueling station, please remove the fuel nozzle by lifting it upwards out of the slot and then moving it away in a downward direction. After you have opened the fuel tank flap and removed the tank lid, the dispenser nozzle can be placed on the vehicle’s tank nozzle.
Different couplings can be installed on the stations. Refueling instructions for the two common couplings WEH and Walter can be found here as PDF file: WEH
.3. Locking the nozzle:
Make sure that the locking ring is snapped forward on the tank coupling. Always check that the fuel nozzle is properly locked into place. 4. Start of the refueling process:
You can then start the refuelling process by pressing the green button on the dispenser. Don’t be startled – there is a test surge at the beginning, as the system tests whether the connection is secure and how much hydrogen is still in the tank.5. Termination of the refueling process:
The refuelling process ends automatically and the green button lights up or stops blinking. Now you can release the locking device by activating the small crossbar on the fuel nozzle lever or by pressing the white button on the fuel coupling’s locking ring and pulling the ring towards you.6 Re-hook the tank nozzle:
Hang the dispenser back into place, going from the top down. Please check that it is correctly engaged, otherwise the system will not be able to complete the refuelling process and prepare for the next refuelling. Now just close the fuel filler flap, take the receipt and enjoy your emission-free ride!
