The article presents the state of existing and future forecasts for a vehicle park equipped with fuel cells in the world. Reference has also been made to the current and future situation in the area of hydrogen refueling infrastructure in the world. The situation in the above-mentioned area in Germany is discussed, which is one of the leading countries in the hydrogenization of motor transport. A proposal for the development of hydrogen propulsion technology in Poland has been presented. In a similar scope, reference is made to the issue of electromobility in road transport, both in the world, in the EU, and in Poland.

Alternative Propulsion Systems

The increasing demand for air travel leads to more pollution produced by air transport. At the same time the fuel prices are constantly rising. Therefore, it becomes necessary to find alternative energy sources for aircraft (alternative fuel, motors). In this article alternative propulsion systems (fuel) that can be used in aviation, their advantages and disadvantages are reviewed.

Alternative Propulsion Systems

This paper presents a simulation-based analysis of hybrid and plug-in hybrid propulsion system concepts for diesel-electric multiple unit regional railway vehicles. These alternative concepts primarily aim to remove emissions in terminal stops with longer stabling periods, with additional benefits reflected in the reduction of overall fuel consumption, produced emissions, and monetary costs. The alternative systems behavior is modeled using a backward-looking quasi-static simulation approach, with the implemented energy management strategy based on a finite state machine control. A comparative assessment of alternative propulsion systems is carried out in a case study of a selected regional railway line operated by Arriva, the largest regional railway undertaking in the Netherlands. The conversion of a standard diesel-electric multiple unit vehicle, currently operating on the network, demonstrated a potential GHG reduction of 9.43–56.92% and an energy cost reduction of 9.69–55.46%, depending on the type of service (express or stopping), energy storage technology selection (lithium-ion battery or double-layer capacitor), electricity production (green or grey electricity), and charging facilities configuration (charging in terminal stations with or without additional charging possibility during short intermediate stops) used. As part of a bigger project aiming to identify optimal transitional solutions towards emissions-free trains, the outcomes of this study will help in the future fleet planning.

Alternative Propulsion Systems

Urban environments depend on the efficiency of logistics activities, which due to several negative impacts are not desirable in cities. Researchers are paying increasing attention to the development of environmentally friendly logistics systems, by applying electric vehicles, hybrid vehicles, cargo trams, and other vehicles to alternative propulsion systems. To achieve environmentally-friendly logistics systems, researchers have defined several "scenarios", to achieve sustainable transport, with the solutions presented in this paper. Also, the paper analyzes the role and importance of the use of e-bikes in CITY logistics, regarding sustainable transport.
