Many years of ongoing development of the world's largest car manufacturers in the area of construction of new alternative propulsion systems of motor vehicles and their gradual practical application in operation must clearly receive a positive appraisal. Running such vehicles significantly reduces the impact of their operation on the environment and it also addresses the threat of depletion of the reserves of traditional raw materials, in this case of oil. Along with the positive features, however, the use of alternative propulsion systems in transportation also presents a number of technical problems. The most crucial issues, according to the type of used fuel, include where to store the fuel in the vehicle itself, where every kilogram of weight carried in addition to the normal weight means higher consumption, lower range and a significant change in the handling characteristics of the vehicle, with consequent impact on the continuity and safety of traffic. Designers have been struggling with higher weight and its distribution in the vehicle in most green vehicles. In the case of electromobiles, the issues include capacity, size and location of batteries, while in vehicles powered by natural gas (CNG, LNG) or hydrogen, the problems include the size, number and location of the pressure vessels and similar issues. The search for new suitable materials and their processing technology is therefore a major requirement and condition of further development and use of alternative fuels. A necessary condition of a further increase in the number of green vehicles in operation is to achieve the prices of vehicles comparable to vehicles burning conventional fossil fuels, or their tax or other advantages, so that the acquisition and operation of such a vehicle is also economically interesting for the owner.
