“…An analysis by Marin focused on evaluating the impact of hydrogen and electricity supply on the cost and GHG emissions of a case study of GO transit along the Lakeshore corridor in Toronto, and this revealed that using scaled-up fuel cells within the existing Bombardier ALP-46A locomotives was reasonable [15]. Furthermore, multiple studies have investigated different design and operation aspects of hydrogen rail systems.…”

“…A major challenge for rail electrification in an urban area like the GTA is the electricity consumption of the transportation system and the consequent grid stability issues [6]. Contrary to electricity, hydrogen transportation systems will not impose excessive loads to the grid because the hydrogen can be produced at times of surplus power and stored for later use, to meet heat and electricity demands An analysis by Marin focused on evaluating the impact of hydrogen and electricity supply on the cost and GHG emissions of a case study of GO transit along the Lakeshore corridor in Toronto, and this revealed that using scaled-up fuel cells within the existing Bombardier ALP-46A locomotives was reasonable [15].

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.

“…Other benefits include increased accessibility and mobility, reduced congestion and lower air pollution [6]. The implementation of new technologies such as electric and fuel cell systems has made rail transit even more attractive from an environmental perspective by further decreasing greenhouse gas (GHG) [7,8] and pollutant emissions [9]. For example, when hydrogen in a fuel cell is used to generate electricity or combusted with air, the only by-products are water, heat and low-levels of NOx, depending on the source of hydrogen and its impurity [9].…”

Alternative technologies have emerged to reduce the greenhouse gas (GHG) emissions of traditional commuter rail systems powered by diesel. Even larger reductions can be obtained with energy production from renewable resources. This paper uses the commuter rail system in Montreal, Quebec, as a case study for implementing alternative technologies, namely, complete electrification of the network (only one of the existing five lines is electrified) and hydrogen fuel cell-powered trains. It is important to note that the main source of electricity generation in Quebec is hydropower which is offered at a relatively low cost. Several criteria were considered to determine the most suitable alternative including GHG emissions from operation and fuel production, operation and capital costs, and technological and commercial viability. Electrification of the commuter rail system would decrease annual emissions by 98% which is more than 27,000 tons. The GHG reductions for hydrogen trains are lower than electric trains but still substantial. The operation costs favor the electrification scenario; however, the high costs of electrical infrastructure make hydrogen trains more competitive since additional infrastructure is unnecessary. However, hydrogen trains remain a new and unproven technology; uncertainties associated with it should be settled before full implementation.

“…The study addressed the need for investments in R&D, demonstrations, skilled people and infrastructure required for the development of fuel cell technologies and transition from petroleum to hydrogen in a significant percentage of vehicles sold by 2020. Other studies considered hydrogen rail transportation ( [11], [12]), comparing it with the current diesel fuel supplying system in Ontario.…”

ElsevierSánchez Díaz, C.; Abad, B.; Hübner, S.; Alfonso-Solar, D.; Segura Heras, I. (2011). Wind park reliable energy production based on a hydrogen compensation system. AbstractPower production from renewable energy resources is increasing day by day. In the case of Spain, in 2009, it represents the 26.9% of installed power and 20.1% of energy production. Wind energy has the most important contribution of this production. Wind generators are greatly affected by the restrictive operating rules of electricity markets because, as wind is naturally variable, wind generators may have serious difficulties on submitting accurate generation schedules on a day ahead basis, and on complying with scheduled obligations. Weather forecast systems have errors in their predictions depending on wind speed. Thus, if wind energy becomes an important actor in the energy production system, these fluctuations could compromise grid stability. In this study technical and economical viability of a large scale compensation system based on hydrogen is investigated, combining wind energy production with a biomass gasification system. Combination of two systems has synergies that improve final results. In the economical study, it is considered that all hydrogen production that is not used to compensate wind energy could be sold to supply the transportation sector.
