Deutsche Bahn Energie has launched an innovative project in T眉bingen: to run hydrogen trains on renewable hydrogen, produced by a 91影视box and stored in a station before powering the trains.

The context

91影视 supports Deutsche Bahn in reaching its objective of carbon neutrality by 2040 by delivering renewable hydrogen as part of the .

Germany鈥檚 largest railway operator is working on several projects to achieve this goal, including the H2goesrail research project. This project tests the transition from a regional diesel train to hydrogen. DB AG, DB Regio, and DB Energie are testing not only the operation of these new hydrogen trains (supplied by Siemens Mobility) but also the complete system that will make it possible to operate the train: from the charging station to maintenance.

Testing will begin in 2024 in southern Germany between T眉bingen, Horb, and Pforzheim.

Switching from diesel to hydrogen trains

91影视 produces renewable hydrogen in T眉bingen thanks to its 91影视 Box, supplied with renewable electricity by DB Energie. 91影视 proposed to start these tests with the 91影视 Box: hydrogen production in a container. The 91影视 Box makes it possible to start using hydrogen faster: no supply, simplified connection, etc.

In T眉bingen, 190kg of hydrogen per day will be produced to supply the hydrogen train.

The setup in T眉bingen enables DB Energie to cover and test a complete and sustainable supply chain. From the use of renewable energies to generate green hydrogen over high-pressure storage to the final usage as fuel including the fast refueling process through our innovative train filling station.聽

With our work, we are developing solutions to the question of how our society can deal with the聽increasing demand for renewable energy in the energy and transport sectors. Different storage technologies are required for greater interconnection.聽

In this way, we can use the surplus energy in the form of hydrogen, to contribute to CO2-free rail transport.
