The global rail market is experiencing growth due to urbanization, road congestion, and a shift towards eco-friendly transportation. ABB, a key player in the rail sector, unveiled its latest innovation at the Innotrans show in Berlin – the Pro series traction battery. This cutting-edge battery offers rapid charging, high energy density, and over 20,000 cycles of lifetime. It enables regenerative braking in hybrid trains, leading to more than 30% fuel savings and a comfortable, emission-free passenger experience. The battery's compact design allows for more passenger space and operates efficiently even in low temperatures. While hydrogen remains a future option for decarbonization, ABB's battery serves as an important bridge, offering modularity, scalability, safety, and efficiency. Beyond hybrid trains, ABB is exploring traction battery applications in trams to enhance infrastructure flexibility. The focus remains on leveraging electric technologies to improve rail sustainability amidst the gradual transition towards more advanced solutions like hydrogen.
