The purpose of this paper is to comprehensively investigate and study various aspects of using hydrogen as a sustainable and efficient fuel for vehicle propulsion. Hydrogen is considered the fuel of the future, and this paper deals with the methods of its production, storage, transportation and application, the advantages and disadvantages of its use, as well as projects aimed at the commercialization of hydrogen in the transport sector. Different types of fuel cells that produce electricity and are an integral part of the vehicles of the future are described, as well as their impact on the environment, and the progress they have had throughout history, from accidental discovery to the present day. Hydrogen systems have the potential to significantly reduce greenhouse gas emissions and reduce human dependence on fossil fuels. Consequently, they have a positive impact on the environment, which is the main reason for the desire to expand the hydrogen economy. The price of hydrogen cars and hydrogen itself is higher compared to gasoline, diesel and today's cars, but it is expected that over time and with future investments the price will decrease and become competitive in the market.
