IntroductionConsidering the current trend of fuel consumption in the automobile industry, it is assumed that humanity will deplete oil reserves for transportation over the next 50 years. British Petroleum (2013) assumes in its annual report that "proven global oil reserves at the end of 2012 reached 1,668.9 billion barrels, enough to meet 52.9 years of global production." Since the only widely distributed type of automobile fuel is oil, it will be problematic to move from one place to another if oil runs out and no other types of fuel will be introduced at that time. It is therefore essential to find an alternative type of fuel to oil. In the automotive industry, among all the options available, hydrogen appears to be proving to be a superior alternative to petroleum in terms of its use as a fuel in automobiles. Hydrogen as a fuelMany arguments demonstrate that hydrogen is an exceptional alternative to oil. The main reason is that it has the highest energy-to-mass ratio than any other chemical because it is the lightest element on the periodic table. This 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 carried. Secondly, it is ecologically harmless and poses no threat to the environment. When burned with oxygen, thermally or electrochemically, it produces only water, energy and insignificant amounts of nitric oxide, air pollutants, which do not pose much danger to the environment. 'atmosphere. In addition, the main source of hydrogen is water, an almost infinite resource (Schlapbach 2009, 809).Operating principleCurrently, engines are divided into two categories, because there are two m...... middle of paper ...... urn 2012, 16). Given this information, it can be assumed that hydrogen will be one of the most used fuel types in the future, if the problems are resolved.ConclusionCurrently, the future of alternative fuel types is unclear , because they are not able to replace them. oil right now. It may take many years to revolutionize the global automobile fleet. But there is no doubt that hydrogen has high potential and can be expected to be used in the future, at least to some extent, and has a guaranteed place in strategies of the automobile industry. If the current problems are solved, hydrogen will serve humanity in the long term, because the water required for hydrogen extraction can be considered an unlimited resource. But to ensure this, long-term support from top scientists, engineers and sponsorship from governments of developed countries is needed...
