Hydrogen Fuel Vs. Fossil Fuel

Hydrogen is a high-quality energy and is used to power fuel cell vehicles. Fossil fuels, which mainly include petroleum, coal and natural gas, provide for the major extent of energy needs around the globe today.

Hydrogen readily combines with other molecules. The three ways generally used to liberate hydrogen are: using heat and catalysts to "reform" hydrocarbons or carbohydrates; electricity to split (electrolyze) water; experimental processes based typically on sunlight, plasma discharge or microorganisms. Fossil fuels are non-renewable source of energy. They were formed from the organic remains of prehistoric plants and animals and have been transformed into to carbon-containing fuels by geological action over millions of years.

Hydrogen-fueled vehicles emit no greenhouse gases or other pollutants. During combustion, hydrogen produces only water vapor. On the other hand, the combustion of fossil fuels is the largest source of atmospheric pollution. Combustion of coal and petroleum are said to be responsible for the release of greenhouse gases such as carbon dioxide and nitrous oxide into the atmosphere.

Hydrogen fuel is very efficient. More energy is extracted from this fuel source than with conventional power technologies, according to Tobin Smith for Billion Dollar Green. Fossil fuels have a high combustion rate and are capable of releasing tremendous amount of energy.

Hydrogen is currently expensive because it is difficult to generate, handle and store. Fossil fuels are less expensive in comparison.

Fossil fuels serve as the primary source of energy at present. However, fossil fuel reserves are gradually depleting. Although hydrogen fuel is being used on an experimental level at present, it has great potential for the future.
