Two non-electrified railway lines, one in Norway and the other in the USA, are analysed for their potential to be electrified with overhead line equipment, batteries, hydrogen or hydrogen-battery hybrid powertrains. The energy requirements are established with single-train simulations, including the altitude profiles of the lines, air and rolling resistances, and locomotive tractive-effort curves. The composition of the freight trains, in terms of the number of locomotives, battery wagons, hydrogen wagons, etc. is also calculated by the same model. The different technologies are compared by the criteria of equivalent annual costs, benefit–cost ratio, payback period and up-front investment, based on the estimated techno-economic parameters for years 2020, 2030 and 2050. The results indicate the potential of batteries and fuel cells to replace diesel on rail lines with low traffic volumes.

“…They used three different power management scenarios in a hybrid tramway over the rail routes in Sevilla [22]. In another experimental study, an English research group developed numerical models and used a typical trip and train system as the benchmark [23]. Between the proposed configurations of the study, it turned out that the most optimal topology only needed a tank of 27 kg of hydrogen to complete each trip.…”

“…Hence, the parameters of interest are estimated based on statistical analysis. The latter is only used when the drive cycle is highly repeatable and the simulation can be undertaken by means of analytical methods [23]. Since the UPE drive cycle does not change during different trips as based on our multiple data collection processes, we have used a simple theoretical model to calculate the demanded duty cycle based on the collected drive cycle.…”

A hydrogen rail (hydrail) powertrain is conceptualized in this study, using drive cycles collected from the trains currently working on the Union Pearson Express (UPE) railroad. The powertrain consists of three preliminary different subsystems: fuel cell, battery, and hydrogen storage systems. A backward design approach is proposed to calculate the time-variable power demand based on a "route simulation data" method. The powertrain components are then conceptually sized according to the calculated duty cycle. The results of this study show that 275 kg of hydrogen is sufficient to satisfy the daily power and energy demand of a hydrogen locomotive with drive cycles similar to the ones currently working on the UPE rail route.World Electric Vehicle Journal 2019, 10, 32 2 of 14 specifically for transportation applications. This can also prevent grid fluctuations and improve the flexibility of the electricity grid and help in controlling the intermittency of renewable systems [7][8][9][10][11][12].Hydrogen transportation is a multidimensional issue that can be analyzed from different aspects including, but not limited to, hydrogen production, refueling station infrastructure, powertrain components topology, sizing, and control. Evaluating the infrastructural requirements and energy consumption of such a system is an essential part towards commercialization. In that sense, the high portion of clean electricity, generated by nuclear and renewable sources, in Ontario's supply mix provides a unique opportunity for development of a hydrogen transportation system.

“…The energy storage systems required for rail vehicle applications are commonly selected based on various technical and design analyses which consider factors including energy and power densities, size and weight characteristics, and cost and operational service lifecycles. The characterisation of the main energy storage devices for railway applications can also be found in [6][7][8][9][10][11][12]. Battery, flywheels and fuel cell technologies are considered as a main energy source for all types of rail vehicles [8][9][10][11][13][14][15][16], and capacitors/super capacitors are generally used for light rail vehicles [16][17][18].…”
