Linde and RVK New Station
  • New Linde technology enables refueling of up to 20 fuel cell-powered buses per day
  • Long-term hydrogen supply from Linde
  • Project co-funded by Federal Ministry of Transport and Digital Infrastructure

Pullach/Cologne, Germany – In the presence of high-ranking local politicians and invited guests Linde (NYSE: LIN; FWB: LIN) and regional transport company Regionalverkehr Köln (RVK) presented an innovative hydrogen filling station for fuel cell buses to the public today.

With a capacity of up to 20 refills per day the new station located near Cologne, Germany sets the stage for supplementing the RVK bus fleet with emission-free vehicles.

“Clean hydrogen will make a significant contribution to a climate-neutral energy supply,” said Jens Waldeck, President Region Europe West, Linde. “Local public transport is playing a pioneering role here. Just like the first hydrogen filling station for trains that Linde is installing in Northern Germany, this modern bus filling station represents an important milestone in this transition.”

Eugen Puderbach, Managing Director, RVK, expressed his thanks to all shareholders, sponsors and partners: “I consider all my fellow campaigners as pioneers who recognized the value of this alternative drivetrain for effective climate protection early on and who had the courage to jointly design and develop this project.”

The hydrogen supplied by Linde is stored in two low-pressure tanks with a combined capacity of approximately 900 kilograms. For the first time, a new high-pressure storage technology developed by Linde is being used: constant pressure tubes ensure that the refueling pressure always remains at a constant level, even as the storage tank volume decreases. This has the significant benefit of enabling multiple back-to-back fillings even for larger vehicles, such as buses.

The core of the hydrogen refueling station are four Ionic Compressors, developed and supplied by Linde Hydrogen FuelTech. This technology that is well-proven with car filling stations – bring the hydrogen to a storage pressure of around 500 bar (7,250 psi). The compressors can be operated with different load profiles, guaranteeing a particularly high service level at the filling station.

The project is being co-funded by the German Federal Ministry of Transport and Digital Infrastructure as part of the BIC H2 (Buses, Infrastructure, Cologne Region) initiative.

Linde is a global leader in the production, processing, storage and distribution of hydrogen. It has the largest liquid hydrogen capacity and distribution system in the world. The company also operates the world’s first high-purity hydrogen storage cavern coupled with an unrivalled pipeline network to reliably supply its customers. Linde is at the forefront in the transition to clean hydrogen and has installed 190 hydrogen fueling stations and 80 hydrogen electrolysis plants worldwide. The company offers the latest electrolysis technology through its newly formed joint venture ITM Linde Electrolysis.
