In recent years, hydrogen is of particular interest among alternative fuels for vehicles, which has a high potential for use as a motor fuel today. Hydrogen and its mixtures for transport really have good opportunities to replace petroleum gasoline. The article discusses the features of hydrogen as a fuel for thermal engines. Observed in the world in recent decades, increased attention to hydrogen as a fuel and energy carrier is determined by the following main features: hydrogen reserves are almost unlimited; hydrogen is a universal energy resource that can be used to produce energy by various technologies, be (stored, transported, used) in gaseous, liquid and bound states; among the types of organic fuel, hydrogen has the highest calorific value per unit mass and the least negative impact on the environment. The article presents a systematic analysis of the use of hydrogen in heat engines, .the features of hydrogen combustion are determined, the advantages and disadvantages of its application are shown on the basis of a comprehensive analysis. It is concluded that the more promising use of hydrogen in road transport is associated with the development of fuel cells
