How can we make transport even greener in the future? We have established partnerships to design and develop eco-friendly transport solutions for tomorrow. One particularly climate-friendly technology is the use of green hydrogen in propulsion technology.
H2goesRail - hydrogen system for rail transport
Deutsche Bahn is currently testing solutions for supplying trains with hydrogen. DB Energie has developing a mobile hydrogen filling station for this purpose.
Green hydrogen is produced directly on site, using power from renewable sources, goes into a mobile storage tank before being processed and cooled in an adjacent tank trailer. Lower energy consumption and shorter refueling times will be achieved through communication between the train and the refueling station and a pressure regulated refueling control system. The innovative DB Energie tank station will refuel a hydrogen train in the same time as it would take to refuel a diesel train. In the future, this will enable smooth refueling even in closely timed regional and local transport.

Under the name "H2goesRail" we are testing a completely new hydrogen system for rail transport in partnership with Siemens Mobility. Alongside DB Energie’s new hydrogen filling station concept, a special hydrogen train has also been developed. Siemens Mobility is building the new Mireo Plus H for this purpose. It has a hydrogen drive system consisting of a fuel cell and a battery.
The aim of the project is to replace diesel multiple units in regional service. This new propulsion technology and the green hydrogen will reduce local carbon emissions to zero. Trial operation between Tübingen, Horb and Pforzheim is planned to start in 2024.
Climate-friendly hydrogen fleet on rail
In collaboration with the Rhein-Main-Verkehrsbund (RMV), our DB subsidiary "start" has been operating the first trains of a new hydrogen fleet in regional rail transport in Hesse since December 2022 .
The Alstom Coradia iLint trains are powered by a hydrogen fuel cell. It generates electrical energy for the drive. The trains score double points in terms of environmental protection. They operate with zero local emissions because they only release water vapor and heat into the environment. In addition, they run almost silently and thus protect residents along the routes from railroad noise.
The entire fleet is scheduled for deployment in passenger transport by the end of June 2023. The trains will then be running on four lines in the Taunus subnetwork in the Rhine-Main region, some of which have not yet been electrified. Our DB Regio maintenance depot in Frankfurt-Griesheim will be responsible for maintaining the vehicles.
Hydrogen technology at DB Regio
We are also advancing climate friendly transport on the roads, for example in North Friesland. There, the DB subsidiary Autokraft is operating two buses that run on hydrogen fuel cells in a pilot project in the regions of Niebüll and Husum. The buses come from the Portuguese manufacturer CaetanoBus and should have a range of up to 400 kilometers. The green hydrogen for this pilot is produced from surplus wind power. The buses can refuel at two publicly accessible hydrogen filling stations. This project has been given the name "eFarm".
In the district of Friesland in northern Germany, five new hydrogen buses will take passengers to their destinations in a climate-friendly way starting in late 2023. Our DB subsidiary Weser-Ems-Bus is taking care of the purchase, operation and maintenance of the vehicles. The buses will be refueled at a new hydrogen filling station being built in Schortens. Both the buses and the refueling station belong to the HyFri project, which is setting the signals for an expansion of the local hydrogen economy in the region. The project name HyFri combines the words hydrogen and Friesland.
In addition, we have signed a framework agreement with the manufacturer Caetanobus for the supply of around 60 hydrogen buses. The vehicles are expected to be delivered successively beginning in early 2024 and will then be active on the roads of Lower Saxony and Schleswig-Holstein. As well as their climate-friendly drive system, the buses have another advantage: they can refuel faster than the batteries of a purely electric bus can be charged and have an impressive range of up to 550 kilometers.
