Hydrogen Economy
The term hydrogen economy is defined as a fossil fuel free environment, instead of fossil fuels like petroleum, gasoline, diesel etc.,( i.e., the product extracted from the coal ) for a vehicle, power plant and industrial usage, the clean fuel called hydrogen fuel replaced. this hydrogen is either in the form of liquid or gaseous state replace the presence of fossil fuel in the environment. it provide the exactly same amount of energy respect to fossil fuel but differs in quantity of usage The main advantages of introducing hydrogen economy is zero emission i.e the current emission like CO, HC and NOx are all eliminated and the resultant of the combustion of the hydrogen fuel is simple water vapor, which is environmental friendly and helps to reduce the green house effect. The main disadvantage is initial investment is high and needed of complex structure for hydrogen usage — Preceding unsigned comment added by Raknash (talk • contribs) 04:48, 17 April 2018 (UTC)
