Hydrogen fuel is thought to be a cheapest energy source in coming future because earth’s most part is covered with water. Converting water to hydrogen and oxygen is already been achieved but now the plans are to make it as an alternative source of energy. Hydrogen is most abundant element in universe, it’s not found in gas state but mostly in the combined with other elements for example oxygen and Hydrogen forms H20 (water) and method used to separate oxygen and hydrogen called electrolysis. NASA uses Hydrogen fuel cell energy for launching their shuttles into the space here you can understand if how powerful hydrogen energy is. Hydrogen also found in Hydrocarbons like Gasoline that we use daily in our vehicles but that is not pure form, if any vehicle run using pure Hydrogen it will produce zero percent pollution. How Hydrogen Energy work?
What are Hydrogen fuel cells?
Hydrogen fuel cells are made up of carbon fiber tanks in which hydrogen and oxygen compressed on high pressure round about 10000 PSI where when these gases react with one another produces electricity, water and heat.
Many other famous and known vendors also making contribution for research and development work such as BMW, Mercedes Benz, Ford and Nissan, this will be the first plan on which these many wanders are contributing. Now we have to wait and see if how much time it will take to start mass production and become a well known energy source.
