MannTek plays a significant role in the building of the world’s first sLH2 refuelling station.
Teaming up with Linde Engineering, Daimler Truck have built the world’s first Subcooled Liquid Hydrogen (sLH2) refueling station in Wörth/Rhein. The new public sLH2 refueling station sets a benchmark in terms of energy efficiency and performance and the project aims to set the industry standard for hydrogen fueling.
MannTeks coupling solution makes it all possible by providing a tight connection to the atmosphere, a robust thermal insulation and making the process safe without any spillage after disconnetion. The sLH2 technology also allows for high flow delivery of more than 400 kg of hydrogen per hour and filling 80 kg of liquid hydrogen can be completed in ten to fifteen minutes. In short, making the transition to using sLH2 as a fuel safe, fast and simple.
”This project has shown that liquid hydrogen is a part of the future of green fuels and transportation – and our coupling makes this possible”, says Guanying Li, Senior Engineer LH2. “This initiative from Daimler Truck and Linde Engineering shows that the world is ready for the next move”, adds Gerhard Kopplin, Technical Director.
Aim: To set the industry standard for liquid hydrogen fueling
Daimler Truck and Linde Engineering are aiming to establish a common refuelling standard for hydrogen-powered trucks, the technology is made openly available to all interested parties via an ISO standard. As a result, both companies offer a high level of transparency and openness around the relevant interfaces of the jointly developed sLH2 technology.
The MannTek team is very much a part of the process of setting the new global standards for the industry. This includes standards for both the fueling protocol and the coupling process, containing both the interface-geometrics and technological requirements.
Now Daimler Truck and Linde Engineering call upon other OEMs, infrastructure companies and associations to apply the new liquid hydrogen standard and thereby establish a global mass market for the process.
Lighthouse project
Daimler Truck and Linde Engineering are now also initiating a lighthouse project where five companies are chosen to gain first experience in CO2-free long-distance transport with Mercedes-Benz GenH2 Truck which will be refuelled at the now open public sLH2 refuelling station. The liquid hydrogen is provided by Linde, which has the largest liquid hydrogen capacity and distribution system in the world.
”Liquid hydrogen is one part of the answer to create a climate neutral transport infrastructure and MannTek have the answer how to manage it safely. We are happy and proud to be a part of this and excited to see our product be a part of the sustainable transport future. Developing global standard and solutions in a close collaboration with our clients like this is how we do our best work. That’s what we call the MannTek way”, says Markus Bäckström, CEO MannTek.
MannTek sLH2 nozzle system
Below we have given some short notes on what our products are doing at the sLH2 refueling station through screenshots from the pressfilm above.
The MannTek LH2 nozzle (DN20 – nozzle with pneumatic activation) is removed from the heated parking adaptor.
Truck driver pushes and turns the nozzle clockwise to the mechanical stop, indication sign is shown on the protection cover.
PLC (Programmable Logic Controller, monitoring and control unit) reads sensors and signals that the nozzle is connected.
Truck driver presses the start button on the PLC.
The PLC reads sensors and provides pressure until it detects a full tank and shuts off the pump.
The PLC is communicating that the process is done and you can see a summary of the refuelling process in the display.
Then return the nozzle back to the heated parking adaptor.
