Siemens presents its new hydrogen fuel cell train with 1,000 km of zero-emission range

H2goesRail project: Deutsche Bahn and Siemens Mobility are developing a hydrogen train and a hydrogen tank trailer.

The joint project “H2goesRail” is developing a completely new global hydrogen system for the railway.

First start-up of the Mireo Plus H hydrogen train from Siemens Mobility and the rapid mobile hydrogen refueling tanker trailer from Deutsche Bahn.

The “H2goesRail” project is an important step in moving away from diesel and advancing the transition to climate-friendly transport.

Deutsche Bahn (DB) and Siemens Mobility presented their innovative system for the first time at the Siemens plant in Krefeld: the new Mireo Plus Hthe next generation hydrogen trainand a new mobile hydrogen storage trailer.

The train and its new infrastructure are intended to replace diesel trains of multiple units in suburban and regional transport and to reduce rail-related CO2 emissions to zero.

The H2goesRail project will not only test the use of hydrogen for rail, but will also significantly advance the technology.

Each train can save up to 45,000 tonnes of CO2 over its 30-year lifespan compared to the same car journeys.

As a two-car train, the Mireo Plus H of the H2goesRail project has a range of up to 800 kilometers, is as powerful as its multi-unit electric counterpart, has a tractive power of 1.7 MW which provides acceleration up to 1.1 m/s2 and a top speed of 160 km/h. The three-car version has a range of up to 1,000 kilometers.

A key element needed for hydrogen technology to be competitive with diesel in day-to-day operation is a fast charging process. To do this, DB has developed a new method which, for the first time, allows a hydrogen train to be refueled as quickly as a diesel train. This is a particularly important factor given the strict schedule of DB’s regional passenger service. Rapid refueling of hydrogen trains will make this technology competitive in day-to-day operations.

Hydrogen trains have a particularly climate-friendly drive technology, as they operate emission-free with green hydrogen and only emit water vapour. In the H2goesRail project, for example, the hydrogen train will save around 330 tonnes of CO2 in one year on the Tübingen-Pforzheim route, compared to a diesel-powered train. In general, the Mireo Plus H saves 520 tons per year depending on the route profile (calculated on a mileage of 200,000 kilometers).

Hydrogen will be produced in Tübingen by DB from green electricity taken directly from the overhead power line.

The Mireo Plus H will begin trials in Baden-Württemberg in 2023. During its planned passenger service in 2024, the hydrogen train of the H2goesRail project with Deutsche Bahn will provide regular passenger service between Tübingen, Horb and Pforzheim and will replace a diesel train.
