The future of hydrogen technology starts todayA climate-friendly transportation transition is essential for dealing with climate change. In a joint project, Deutsche Bahn and Siemens Mobility are testing a brand-new complete system consisting of a newly developed train and a newly designed filling station. Siemens Mobility is developing the next generation of hydrogen trains that are based on the proven, high-performance Mireo commuter train, which is also used in battery-powered operation. Equipped with a fuel cell drive and a lithium-ion battery, it provides local, emission-free mobility on non-electrified routes. Learn all about this project and join us when we bring the future of hydrogen technology on rails. This page will provide you with regular updates on our project milestones.
Collaboration with Deutsche Bahn (DB)
Together with Deutsche Bahn we are working to advance the climate-friendly transportation transition. For our joint project „H2 goes Rail“, DB is developing an innovative hydrogen filling station that enables a hydrogen train to refuel within the same time period as a diesel train. For more information, visit the Deutsche Bahn website.
The Mireo Plus H is launched in the Krefeld plantFor a climate-friendly transportation transition in rail: Deutsche Bahn and Siemens Mobility present the Mireo Plus H – the next generation of hydrogen trains – at the production plant in Krefeld. The newly designed, mobile hydrogen storage trailer is also part of the presentation. As a two-car train, the Mireo Plus H has a range of up to 800 kilometers. The hydrogen train is as powerful as electric multiple units. It features a high traction power of 1.7 MW for up to 1.1 m/s² acceleration and a maximum speed of up to 160 km/h. The three-car version of the train has a range of 1,000 kilometers.

All facts at a glance
What powers hydrogen trains? How does the Mireo Plus H refuel? When does trial operation start? We have summarized all the facts about the joint project with Deutsche Bahn for you.
With hydrogen drive systems, the reaction of hydrogen and oxygen produces electrical energy and water as a „waste product“. These trains can be deployed by DB as a way to become climate-neutral and replace diesel vehicles with alternative drive systems. Green electricity is used to produce the environmentally friendly green hydrogen. DB Energie is responsible for its supply.
Siemens is developing a two-car commuter train with a state-of-the-art hydrogen drive system for one-year trial operation. It consists of a fuel cell and a lithium-ion battery. The Mireo Plus H will be as powerful as electric multiple-unit trains and have a range of 600 kilometers – depending on operating conditions such as the season or the route. A three-car version will have a range of 1000 kilometers. Low life-cycle costs due to low maintenance and repair costs and a top speed of 160 kilometers per hour are the vehicle's distinguishing features.
The hydrogen is produced by electrolysis in a DB Energie mobile filling station at the DB Regio plant in Tübingen. In the so-called electrolyzer, water is split into hydrogen and oxygen by means of electricity. Compressed in a compressor, the hydrogen is stored in a mobile storage unit. Prior to the refueling process, the green fuel is processed and cooled in the adjacent tank trailer. The mobile structure makes further test projects possible. DB Energie develops, tests and optimizes the necessary hydrogen infrastructure.
The train is refueled with hydrogen in a novel process: for the first time, it won’t take longer than the 15 minutes required to refuel a diesel multiple unit. This is an important factor considering the closely timed schedules of DB’s regional train services. This means that hydrogen technology is competitive with the diesel fuel used in everyday operations to date.
Trial operation between Tübingen, Horb, and Pforzheim will begin in 2024 and last for one year. Approximately 120,000 kilometers of scheduled rail service are planned. The route is particularly suitable based on the timetable intervals and topography. The Mireo Plus H from Siemens will replace a diesel railcar used on this route and save about 330 tons of CO2.
