Introduction Considering the current trend of fuel consumption in the automotive industry, it is assumed that humanity will run out of oil supplies for transportation presumably in the next 50 years years. In its annual report, British Petroleum (2013) hypothesizes that “world proven oil reserves at the end of 2012 reached 1668.9 billion barrels, sufficient to satisfy 52.9 years of global production”. Since the only widely distributed type of automotive fuel is petroleum, it will be problematic to travel from one place to another if oil depletion occurs and no other types of fuel are introduced by then. Therefore, it is essential to find an alternative type of fuel to replace oil. In the field of automotive industry, among all the available options, hydrogen seems to prove to be a superior alternative to petroleum in terms of its use as a fuel in automobiles. Hydrogen as a fuelMany arguments prove that hydrogen is an exceptional alternative to oil. The main reason is that it has the highest energy-to-mass ratio of any chemical substance, as it is the lightest element in the periodic table. It is also the main reason why it has been used as a fuel in rockets, where it is necessary to minimize the mass of fuel transported. Secondly, it is ecologically harmless and does not pose any danger to the environment. When burned with oxygen, either thermally or electrochemically, it produces only water, energy, and insignificant amounts of nitrogen oxide air pollutants, which do not pose much risk to the atmosphere. Furthermore, the primary source of hydrogen is water, a practically infinite resource (Schlapbach 2009, 809). Operating principle Currently motors are divided into two categories, as there are two m...... half of paper...... urn 2012, 16). Considering this information, it can be assumed that hydrogen will be one of the most used fuel types in the future, if the problems are solved. Conclusion Currently, the future of alternative fuel types is unclear, as they are not capable of replacing oil at this time. It may take many years to revolutionize the global automotive fleet. However, without a doubt, hydrogen has great potential and is expected to be used at least to some extent in the future, and has a guaranteed place in the strategies of the automotive industry. If current problems are solved, hydrogen will serve humanity in the long term, since the water required for hydrogen extraction can be considered an unlimited resource. But ensuring this requires long-term support from top scientists and engineers and sponsorship from governments in developed countries.
