The analysis focuses on the interrelation between the selected lithium-ion battery technology, the designed energy management strategy, and the fuel cell and battery sizes. In particular, 3 lithium-ion battery technologies and 4 strategies are proposed, leading to a sensitivity analysis composed of 12 cases. For each case, an approach for the optimal sizing of the fuel cell and battery is proposed. A scenario based on a real railway line is introduced and the obtained results are compared with the performance of a traditional diesel-electric multiple unit. The results show that a reduction of the hydrogen price is required so as the hydrogen-based option becomes competitive compared to the diesel-based one. The best result of the sensitivity analysis is obtained with an off-line optimization-based strategy and LTO batteries. eng © 2021 IEEE lithium-ion batteries Sensitivity analysis Hydrogen Fuel cells Propulsion Rail transportation Fuels In-depth Life Cycle Cost Analysis of a Hydrogen Electric Multiple Unit http://purl.org/coar/resource_type/c_c94f
