GREEN ALTERNATIVES FOR ROAD AND RAIL TRANSPORT

Abstract

Environmental pollution with internal combustion engine combustion products has prompted road and rail vehicle manufacturers to look for alternative propulsion energy solutions. One group of road vehicle manufacturers has focused its development on hybrid road vehicle propulsion, i.e. the primary use of electricity, and only as a secondary solution to fossil fuel engines. For the last ten years, intensive work has been done on hydrogen to start road and railway vehicles. The original experiments gave results so that there are already vehicles that use hydrogen for their propulsion. Accelerated development and production of electric road vehicles were directly related to the production and capacity of electric batteries for road vehicles, i.e. the length of charging time. The second reason is the infrastructure, i.e., electrical connections at gas stations for the fast power supply of road vehicles. In order to correctly answer the questions, we will deal with the functioning most generally known power units in recent times, make their mutual comparison and try to answer the most challenging question, which is whether we are smiling green future.
