Siemens Mobility has launched seven Mireo Plus H hydrogen-powered trains on the Heidekrautbahn line in Berlin-Brandenburg, Germany. Operated by NEB, the trains will utilize locally produced hydrogen and fuel cells, offering an impressive operating range of up to 1,200km. With a power capacity of 1.7MW and a top speed of 160km/h, these trains are poised to replace diesel units on NEB's network for a trial period of at least two and a half years. In a bid to transition to eco-friendly transportation solutions, Siemens Mobility has developed the Mireo Plus H trains as part of its modern platform, aiming to contribute to the reduction of diesel train operations. Despite challenges faced by hydrogen-powered rail operations, such as Alstom's recall of its hydrogen units due to reliability issues, Siemens Mobility remains committed to advancing hydrogen train technology. However, recent incidents, like the tube trailer fire at the Leuna Chemical Complex near Leipzig, have underscored the fragility of Germany's hydrogen refueling supply chain. While the fire, caused by a hydrogen explosion, was swiftly extinguished with no reported injuries, it raises concerns about the safety and infrastructure surrounding hydrogen production and transportation. Siemens Mobility's initiative with hydrogen trains represents a step towards sustainable and efficient rail transportation, but ongoing challenges in the hydrogen sector highlight the need for robust safety measures and infrastructure improvements.
