Project partners Wystrach and WaterstofNet made the design specifications of the mobile hydrogen refuelling station (the 'WyRefueler') public. This deliverable is part of work package I2 (‘the design, building and demonstration of a hydrogen mobile refueler’) of the H2-Share project. The deliverable is a short report describing the specifications and the design of the hydrogen storage (tank container) and refuelling station (refueller container), which you can find attached.
The WyRefueler is a standalone tank system for refueling hydrogen tank systems such as those found in buses or trucks. It can provide 120 kg of hydrogen per day. The system is equipped with smart control, works autonomously, and can be accessed 24/7 via remote maintenance.
How does the mobile refueler work?
The mobile refuelling station is designed to be as flexible as possible and serves as a market facilitator, making sure the end-user of the fuel cell electric truck can use the truck and refuel it at their own premises for the H2-Share project demonstration.
The two units (tank- and refuelling container) will be transported to the location where the end-user wants to refuel the truck. The tank container will be used to transport hydrogen between a location with a hydrogen source and the location of the demonstration at the end-user premises (or nearby). The refueller container stays at the end-user premises and uses the hydrogen from the tank container to refuel the truck.
The mobile refueler can be installed in a short time at the place where it is used. After the device is connected, the control system checks the equipment and improves the hydrogen pressure sections. The refueler is ready to use in a short time, so that a first truck, or bus can be filled up with hydrogen. The filling time is about 15 minutes, depending on how big the remaining amount of hydrogen in the truck or bus is. After filling, the bus or truck can be used directly again. The mobile refueler improves the hydrogen pressure sections again, so that a second truck or bus can be filled right after the other. An amount of four trucks or buses can be filled per day in that way. After filling about 10 trucks or buses, the tank container has to be refueled, for which it is driven away with a trailer. During the time the tankcontainer is away for new hydrogen, the mobile refueler is still able to fill up three trucks or buses with hydrogen, coming from a storage. When the tank container is back, it will be connected again to the refueler container and after a short time of improvement, the mobile refueling station is ready to use again.
