Saft, a leading battery manufacturer, has entered into a significant partnership with Siemens Mobility in Germany to provide lithium titanium oxide (LTO) batteries for the Mireo Plus H hydrogen trains. These batteries are integrated into a hybrid fuel cell and battery traction system to enhance the trains' performance and efficiency. During acceleration, the batteries compensate for the power limitations of the fuel cells, while in braking, they help recover kinetic energy. Additionally, the batteries support load levelling during cruising to optimize fuel cell operation. Saft's CEO, Cedric Duclos, highlighted the importance of this project, emphasizing the introduction of LTO batteries on a major commercial rail initiative for the first time. The partnership with Siemens Mobility underscores Saft's commitment to developing tailored solutions for its customers, enhancing safety, reliability, and sustainability. By utilizing advanced battery technology, the hydrogen trains benefit from lower CO2 emissions, extended lifespan, and increased power capabilities, setting a new standard in rail transportation. This collaboration signifies a significant advancement in the adoption of innovative technologies in the public transportation sector, offering environmental and operational advantages.
