Deutsche Bahn (DB) and Siemens Mobility continue to drive the climate-friendly transportation transition in rail. The two partners premiered elements of their innovative complete system at the Siemens plant in Krefeld: The newly developed Mireo Plus H, the next-generation hydrogen-powered train, and a newly designed mobile hydrogen storage trailer. The train and its new infrastructure are intended to replace diesel multiple-unit trains in commuter and regional transport and reduce rail-related CO2 emissions to zero.

The 2goesRail project is being funded as part of the National Innovation Program for Hydrogen and Fuel Cell Technology (NOW GmbH) with EUR 13.74 million by the Federal Ministry for Digital and Transport (BMDV). The funding guideline is coordinated by NOW GmbH and implemented by project lead Jülich.

“In its coalition agreement, the federal government agreed to electrify 75% of the country’s rail network by 2030,” said Michael Theurer, Parliamentary State Secretary in the BMDV. “Here, alternative drives can help reduce emissions from diesel rail transport. This way, we’ll be able to operate virtually climate-neutral on rail routes where full electrification is not possible. The H2goesRail project will not only test the use of hydrogen for rail but substantially advance the technology.”

As a two-car train, the Mireo Plus H for the H2goesRail project has an operating range of up to 800 kilometers, is as powerful as its electric multiple-unit counterpart, and has 1.7 MW of traction power providing up to 1.1 m/s2 acceleration and a top speed of 160 kilometers per hour. A three-car version has a range of up to 1,000 kilometers.

The crucial element needed to make hydrogen technology competitive with diesel fuel in daily operation is a fast refueling process. To provide this, DB has developed a new method that, for the first time, enables a hydrogen train to be refueled as fast as a diesel-powered train. It is an essential factor considering the closely timed scheduling of DB’s regional passenger service. The fast refueling of hydrogen trains will make the technology competitive in daily operations.

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

The hydrogen will be produced in Tübingen by DB using green electricity taken directly from the overhead power line. To service the train, the DB maintenance depot in Ulm will be equipped accordingly.

Siemens Mobility and Deutsche Bahn will also be showcasing the H2goesRail project and the Mireo Plus H at the InnoTrans 2022, the world’s largest trade fair for railway technology held in Berlin.
