More sustainable thanks to alternative drivesOne sign of a sustainable solution is that it supports the progress of all its stakeholders. In the case of railways, this means passengers, operators, nearby residents, and the environment. Siemens Mobility rigorously applies this comprehensive approach to its alternative drive concepts for multiple-unit trainsets and locomotives. Electric drives are quiet, efficient, clean, and reliable – and can be totally carbon-free thanks to sustainably generated electricity. At the same time, Vectron Dual Mode makes an important contribution to sustainable freight transport, because it takes advantage of electricity wherever possible to reduces carbon dioxide, nitrogen oxide, and particulate matter emissions.
Flexibility for any transportation requirementsWith Siemens Mobility, the future is built in. This means that when you choose Mireo Plus B or H or Vectron Dual Mode, you’re choosing the optimal solution for your transportation requirements. With Vectron Dual Mode, you’re also benefitting from the flexibility of the drive technology, for example in order to open up new routes for freight transport.
Sector coupling with green hydrogen
Natalia Westhaeuser, Vice President of New Energy Business at Siemens Energy, has a clear vision of what lies ahead: “Green hydrogen is the oil of the future.” She sees sustainably produced hydrogen as the fuel that will make it possible to exploit the benefits of sector coupling for decarbonizing transportation. Read this interview to learn how Siemens Mobility and Siemens Energy are working together to promote the development of complete solutions for supplying regional trains with green hydrogen.
The sustainable alternative for catenary-free lines
Largely due to concerns about emissions, thousands of diesel multiple units (DMUs) will gradually be taken out of service until 2040 in Europe alone. For various reasons, however, about 40 % of the track kilometers in Germany are still non-electrified. The growing question in mass transit and regional transport is how to keep traffic moving on these sections other than by investing in electric overhead lines. With Mireo Plus H, Siemens Mobility has developed a unique solution. Thanks to hydrogen fuel cells, this state-of-the-art multiple unit has no problem operating without an overhead line. And with its optimally dimensioned tanks, it also achieves long distances.
Sustainable rail vehicles and sustainable hydrogen
Thousands of diesel-electric multiple units are expected to be gradually replaced by eco-friendlier alternatives in Europe by 2040. Because about 40 % of German railway lines still aren’t electrified – mainly branch lines in public mass transit and regional transport – it’s important to identify the technologies that will keep traffic moving on these lines in the future. For many reasons, hydrogen and its conversion in fuel cells are at the top of the list. Siemens Energy and Siemens Mobility have now joined forces to develop holistic hydrogen solutions for rail transportation. Their stated goal is to advance the hydrogen economy in Germany and Europe and promote decarbonization in the mobility sector.
Mireo Plus B replaces diesel multiple units
In the future, rail transport will be powered by battery or hydrogen. The Mireo Plus platform boasts top-notch acceleration values, an impressive maximum speed, and a range that’s more than suitable for everyday use. Jochen Steinbauer, Director of Development for Alternative Drives at Siemens Mobility, talks about the strengths of battery-powered trains and the knowledge gained from successful operation of the Desiro ML ÖBB Cityjet eco prototype.
Mireo Plus decarbonizes Europe’s railways
Although trains with electric drive systems are environmentally friendly, the unfortunate fact is that not all lines are electrified, and that’s likely to be the case for the foreseeable future. So if you wanted to travel “green” everywhere, you’d have to take your electricity with you (in a battery) or generate it on board (with a fuel cell). Or just travel by Mireo Plus, since it does both, and can therefore help decarbonize Europe’s railways in areas that don’t currently have catenaries. The fact it uses up to 25 % less energy not only increases its range but also reduces its running costs on a lasting basis.
The Vectron Dual Mode – Two options are better than one
A modern diesel locomotive that consumes only a few liters of fuel per kilometer offers top results in a very positive way. But you can save even further by using the Vectron Dual Mode. That’s because this locomotive adopts a two-pronged approach in the truest sense of the word: Wherever an overhead wire is available, it is used with a pantograph. Where no overhead wire exists, especially in rural areas, the locomotive runs on diesel. This not only offers tangible benefits for the environment, but is also approximately three times more cost-effective calculated over its lifespan.
