“…3 Road locomotives are subjected to harsh operational environments, are heavier (typically requiring up to 10 times the power of passenger trains) and, consequently, high tractive loads, that ultimately require very high voltage and current for the electrical system, thus, increasing the power management system complexity. 4 From here on, it will be presented an overview of the BOER technology, to be used on freight rail vehicles, with a focus on the available battery technologies and the associated technical, operational and environmental challenges.…”

The rail transport industry has been required to engage with the world effort to reduce the climate effects, as well as the reduction of criteria pollutant and noise emissions, which strongly affects the populations nearby the rail infrastructure. Electric powertrains have been widely used by railways, with its inherent efficiency and cleanliness. However, the required infrastructure has restricted its use to medium to large density traffic corridors, given the large infrastructure and maintenance costs involved. Light to medium loaded rail stretches and large freight rail corridors, running in rural areas, have adopted the diesel-electric powertrain approach, that relies on an onboard diesel generator, with the inherent environmental negative effects, especially to the rail nearby communities. In this context, alternative traction technologies, such as Hybrid-Electric Rail, Hydrogen Fuel Cell Rail and Battery Only Electric Rail, have been considered by the rail industry as potential alternatives. The BOER route, due to the recent battery technology breakthroughs (associated with performance improvements and reduced costs) is set as a promising alternative and has a potential do be used as a decarbonization strategy for both passenger and freight rail systems at low to medium density traffic lines. Nevertheless, the BOER technology sets great challenges, given the high energy and power required by rail vehicles, as well as the harsh rail operational environment, with huge effects on the performance, charging infrastructure requirements, fleet availability, costs, as well as the environmental sustainability associated with the mining and disposal of materials required by the battery chemistries. This paper presents, based on the state of the art available technical literature, an unbiased review of the BOER technology and an assessment of its potential for the freight rail industry, highlighting the associated technical, operational and environmental challenges.

Many new zero-emission propulsion technologies are being developed today due to the need to reduce the atmospheric carbon dioxide emissions. The impact of the transport sector on the environment drives a need for innovation, including innovation in the rail transport sector specifically. At the TRAKO fair of rail vehicles the newest technological solutions have been presented. These new vehicles are expected to take over the rail transport sector in the coming decades. Many of the presented solutions and prototypes focused on using hydrogen as fuel for a system of hydrogen fuel cells, which are then used to produce the electricity needed to drive the vehicle. The development of hydrogen fuel technologies in vehicle drives in recent years allowed for a set of new solutions to appear for all types of rail vehicles and applications. Hydrogen powered rail vehicles for transporting cargo, passengers, and shunting vehicles have been shown. This article provides a discussion of the newest hydrogen solutions and vehicles sent to the market. It was determined that the adoption of such solutions will be mainly restricted by the relative cost of the hydrogen fuel rather than the vehicles or fuel cell technologies themselves. The cost of hydrogen production, when powered by renewable Energy sources to enable reduced carbon dioxide emissions, would need to be reduced to at least $2.50 /kg of fuel in order to satisfy the requirements for widespread adoption.

Strict emission standards mean that the internal combustion engines used in means of transport must meet the standards for the emission of harmful compounds. For this reason, there is an increase in the use of alternative sources of propulsion, including rail transport. The article presents unconventional solutions of drive systems in rail vehicles using hybrid systems and fuel cells. The concept of the realizing project of a special-purpose rail vehicle, which is to be able to be driven from three different sources, was presented. Considerations concerning the selection of the internal combustion propulsion system, which is to be used as an auxiliary in the vehicle, are described. The possibilities of installing the power unit on the vehicle were also presented.
