HYBRID BATTERY HIGH-SPEED TRAIN
In recent years, hybrid trains equipped with onboard power systems, such as batteries, have been emerging as an increasingly efficient and sustainable solution for both partially electrified and completely non-electrified railway lines, still served by diesel trains, with the goal of accelerating the decarbonization process of the sector.
The study conducted by Professor Alessandro Ruvio from ICI-DIAEE Sapienza in collaboration with Dr. Onur Bayrak from Turkish State Railways (T.C.D.D) focuses on the preliminary design of high discharge capacity (C-Rate) traction batteries for a high-speed hybrid train intended to operate in Turkey. The need arises from the difficulty of electrifying certain sections of railway lines, currently under construction, due to high costs, infrastructure constraints, available space, visual impact, etc.
The aim of the study was to analyze, size, and simulate different types of high-power and high-energy lithium-ion batteries (LFP, NMC) to identify the most technologically and economically advantageous solution, also from a performance perspective, considering the specific operational requirements of the train on two sections of the line, totaling about 125 km. Finally, a technical-economic feasibility analysis allowed for a comparison between a fully electrified solution and a hybrid one, highlighting the respective benefits and costs.
