In-depth Life Cycle Cost Analysis of a Hydrogen Electric Multiple Unit Aizpuru, Iosu Olmos Amondarain, Josu Saez de Ibarra Martínez de Contrasta, Andoni Gaztañaga Arantzamendi, Haizea López, Dimas Nieva Fatela, Txomin lithium-ion batteries Sensitivity analysis Hydrogen Fuel cells Propulsion Rail transportation Fuels This paper analyses the life cycle costs of railway projects involving hydrogen electric multiple units. 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. 2022-06-08T13:34:15Z 2022-06-08T13:34:15Z 2021 http://purl.org/coar/resource_type/c_c94f 978-1-6654-0528-7 https://katalogoa.mondragon.edu/janium-bin/janium_login_opac.pl?find&ficha_no=167494 https://hdl.handle.net/20.500.11984/5594 eng © 2021 IEEE IEEE
