IMI to Provide 1-MW Electrolyser for Hydrogen Bus Filling Station in Bielefeld, Germany
The Stadtwerke Bielefeld Group is launching a project to refuel 29 dual-fuel buses with locally produced hydrogen, supported by IMI's supply of a 1-megawatt electrolyser. This electrolyser will be installed at the Bielefeld Innovation Park, utilizing solar energy to produce hydrogen, thereby reducing transport emissions and enhancing local renewable energy use. The initiative aims to tackle decarbonisation challenges faced by German bus operators, as only 27% currently have a permanent hydrogen infrastructure despite growing investments in hydrogen vehicles.

The Stadtwerke Bielefeld Group is implementing a project that will see 29 dual-fuel buses, powered by hydrogen fuel cells and battery-electric drives, refueled with locally produced hydrogen. IMI will supply a 1-megawatt electrolyser for this initiative.
The electrolyser will be installed at the Bielefeld Innovation Park, which features a solar system on the roof of a new bus depot. This local hydrogen production eliminates transport emissions and allows buses to be powered by either solar electricity or locally produced hydrogen from renewable sources.
A report by IMI indicates that 77% of German bus operators are investing in hydrogen vehicles, but only 27% have a permanent hydrogen infrastructure. The project aims to address challenges in decarbonisation related to grid reliability and battery limitations.
