Deutsche Bahn and Siemens Mobility have presented for the first time elements of the overall hydrogen system being developed as part of the H2goesRail joint project: the Mireo Plus H, the latest generation of hydrogen train, and a newly designed mobile hydrogen storage trailer.
According to the companies, the Mireo Plus H has a range of up to 800 kilometres as a two-part multiple unit. The drive power of 1.7 MW enables acceleration of up to 1.1 m/s² and the top speed is stated as up to 160 km/h. A three-part version has a range of 1,000 kilometres.
Next year, the two-car hydrogen train is to start test runs in Baden-Württemberg and, from 2024, will be in service between Tübingen, Horb and Pforzheim for the H2goesRail project, where it will replace a diesel railcar. The route is particularly suitable because of the exemplary frequency of the timetable for regional transport and the varied topography. This phase is also expected to last a year. Around 120,000 kilometres of scheduled rail operation are planned, with savings of around 330 tonnes of CO2.
DB has also developed a new process to make the refuelling of a hydrogen train as fast as that of a diesel multiple unit, which is "an important aspect in view of the tightly timed train sequences in DB's regional services". The hydrogen is produced by DB Energie in Tübingen. In the so-called electrolyser, water is first split into hydrogen and oxygen with the help of green electricity, and the fuel is then stored in compressed form in a mobile storage unit. "The mobile structure enables further test projects on routes that have not been developed so far". In order to be able to maintain the train, the DB plant in Ulm is being equipped accordingly.
