Environmental Protection Agency (EPA) has reported that the levels of carbon monoxide would get worse if people persist to contribute to it with their polluting cars. Everyone needs their car which is fortunately today followed by the urge of reducing pollution too.

There are many pollution-free alternatives available for fuel but the best of them is considered as ‘Hydrogen.’

Hydrogen is the simplest element and also the most abundant element in the universe. It is also found in many organic compounds, particularly the hydrocarbons that frame many of our fuels, such as gasoline, natural gas, methanol, and propane. Unlike nuclear and solar energy which cannot be utilized directly, hydrogen can be used as a motor fuel, directly. It is harmless, has been tested strictly for use in vehicles, and is being used in many vehicles already. It has the utmost energy content of any common fuel by weight (approximately three times more than gasoline) and the shortest energy content by volume (approximately four times less than gasoline).

Hydrogen thereby has been called the "most alternative" of the alternative fuels. When made by electrolysis of water, it does not liberate pollutants of any kind and when used in a fuel cell then even these disappear. In addition to this, no greenhouse gases are generated as there is no carbon in the fuel. All that comes out the vehicle's exhaust or byproduct is drinkable water! Moreover you can get unlimited supply of clean fuel by using hydrogen as the battery to store energy from a renewable source.
