Due to the more use of conventional fuel in the vehicles, a pollution level is increasing day by day. Hydrogen is a potential alternative fuel for the IC engine. Fuel optimization plays a vital role all over the world, Water is the most readily obtainable and affordable source and hydrogen energy has been proven to be more effective compared to electric and gasoline cars. Prices of petroleum oil are increasing day-by-day affecting the life style of common people as well as national economy. That's why we need an alternative for petroleum. In recent days, all country is spending a huge amount of money on research and development of non-conventional energy resources. In the world, the conventional energy sources are limited, and their usage is very high; so alternative sources of energy have tremendous potential in future. Thus world is in crisis to find an alternative fuel for petroleum oils. To fulfill the aim stated before, non-conventional energy systems like solar, battery are developed. Nobody will think for a moment but it's the reality that water can be used as a fuel and hence an energy resource.
