“…Additional trials outside Germany were carried out in UK, Denmark, Norway, Sweden, Italy, the Netherlands, Canada, Austria, and France [26]. The Japanese railway company Hitachi Ltd., in collaboration with Toyota Motor Corporation, has designed, built, and tested a hydrogen-powered passenger train (Hybari) in Japan with a top speed of 100 km/h that can travel up to 140 km on a single filling [28]. The China Railway Rolling Stock Corporation (CRRC) in China has also designed, manufactured, and tested a hydrogen fuel-cell-powered passenger train with a top speed of 160 km/h, and it covers a distance of 600 km before refueling.…”

The majority of rail vehicles worldwide use diesel as a primary fuel source. Diesel engine carbon emissions harm the environment and human health. Although railway electrification can reduce emissions, it is not always the most economical option, especially on routes with low vehicle demand. As a result, interest in hydrogen-powered trains as a way to reduce greenhouse gas (GHG) emissions has steadily grown in recent years. In this paper, we discuss advancements made in hydrogen-powered freight and commuter trains, as well as the technology used in some aspects of hydrogen-powered vehicles. It was observed that hydrogen-powered trains are already in use in Europe and Asia, unlike most developing countries in Africa. Commuter trains have received most of the research and development (R&D) attention, but interest in hydrogen-powered freight trains has recently picked up momentum. Despite the availability and use of gray and blue hydrogen, green hydrogen is still the preferred fuel for decarbonizing the rail transport sector.

The article presents the currently used technologies and solutions for rail vehicle drive systems that can be used in the future. The most popular systems used in locomotives and multiple units are described. In addition, modern solutions such as bi-mode locomotives and hybrid vehicles are shown. The article also discusses the possibility of using ultracapacitors, batteries or fuel cells in order to increase the efficiency of the powertrain of a rail vehicle. The selection of the appropriate solution depends on the intended use of the vehicle and the assumed traction characteristics and requires a thorough analysis including, among others, modeling of the drive system and its management.

The passenger rail transportation system is of strategic importance to the decarbonization of the transportation sector. The use of green hydrogen is an environmentally sustainable option where highly polluting diesel trains currently operate on non-electrified rail lines. This paper proposes a novel adaptive power flow management strategy for urban railway trains powered by a hydrogen fuel cell stack and electrochemical batteries. The fuel cell stack is not dynamically controlled as usual, but it operates in on-off conditions to improve its overall efficiency. It always operates at the maximum efficiency operating point when it provides electrical power (on state) without following the load power variations. Furthermore, the state of the fuel cell stack depends on the state of charge of the electrochemical batteries which is the controlled quantity. As a case study, it is proposed a simulation of a suitably redesigned hydrogen-fuelled railway train operating, over an existing non-electrified line, for the L’Aquila (Italy) urban transportation service. The main components of the railway line and vehicle powertrain are designed, and the hydrogen consumption for railway operation is estimated.
