Saft, a subsidiary of TotalEnergies based in Paris, has supplied its lithium titanate oxide (LTO) traction batteries to Siemens Mobility to power seven cutting-edge Mireo Plus H hydrogen trains in Germany. These batteries, integrated with fuel cells, form a hybrid power system that enables emission-free operation on long-distance routes without overhead supply, propelling the rail sector towards decarbonization. Saft's CEO Cedric Duclos emphasized the breakthrough achieved with this project as the LTO batteries are deployed on a major commercial rail initiative for the first time. The collaboration between Saft and Siemens Mobility aims to enhance safety, reliability, and efficiency in rail transport. The Mireo Plus H trains utilize the LTO batteries during acceleration and braking to optimize energy usage and support fuel cells for maximum efficiency during cruising. Saft's LTO technology offers substantial benefits including a longer cycle life, heightened safety, and superior charge and discharge capabilities compared to traditional lithium-ion batteries, making it ideal for traction applications. This endeavor underscores Saft's commitment to developing tailored solutions for its customers, emphasizing sustainability and innovation. The delivery of LTO batteries to Siemens Mobility commenced in summer 2024, marking a significant step towards greener and more efficient rail transportation.
