Deutsche Bahn and Siemens Mobility present new hydrogen train and hydrogen storage tank trailer
The H2goesRail project will not only test the use of hydrogen for rail, but substantially advance the technology.
Deutsche Bahn (DB) and Siemens Mobility are continuing to drive the climate-friendly transportation transition in rail through H2goesRail, a joint project developing a completely new overall hydrogen system for 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 “H2goesRail” project is being funded as part of the National Innovation Program for Hydrogen and Fuel Cell Technology (NOW GmbH) with €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.
As a two-car train, the Mireo Plus H for the H2goesRail project has an operating range of up to 800 km, is as powerful as its electric multiple-unit counterpart, has 1.7 MW of traction power providing up to 1.1 m/s2 acceleration, and a top speed of 160 km per hour. A three-car version has a range of up to 1,000 km.
One key 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. This is an especially important 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 mileage of 200,000 km).
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.
The Mireo Plus H will start testing in Baden-Württemberg in 2023. During its planned passenger service in 2024, the hydrogen train for the H2goesRail project with Deutsche Bahn will provide regular passenger service between Tübingen, Horb and Pforzheim and replace a diesel train.
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, being held in Berlin.
Michael Peter, CEO of Siemens Mobility, said, “With the Mireo Plus H, we’ve developed the next generation of hydrogen-powered trains that offers a particularly long operating range and faster acceleration. Each delivered train can save up to 45,000 tons of CO2 over its service life of 30 years compared to corresponding travel with cars.”
Dr. Daniela Gerd tom Markotten, Member of the Management Board for Digitalization and Technology at Deutsche Bahn, commented, “With our development of the mobile hydrogen filling station and the related maintenance infrastructure, we are showing that we not only can do mobility, but technology as well.”
