Oh really!!?? You just go down to the local corner hydrogen station, fill the tank, and drive off. We know we cant do that today but what about the future?
We do know for a fact that hydrogen is clean burning, no-poluting, its only bi-product is water when it is burned. Isnt that enough to qualify it as the fuel of the future?
True and it sounds promising but where are you going to get the hydrogen. There are no hydrogen wells or hydrogen mines or hydrogen deposits. About the only way to get hydrogen is by disassociating water. That is, running a current through water that has been made conductive to break it down into hydrogen and oxygen.
Okay, no problem, just plug a hydrogen generator into an outlet and go. Where is the electricity going to come from?
Electric company, right? No, they cant burn hydrogen to make steam to make electricty to make hydrogen to make more steam to make more electricity.
You dont need a very fine pencil to figure out that hydrogen is a very expensive fuel indeed. Indeed, that is all that hydrogen is, a fuel. A fuel as opposed to an energy source. It takes energy to make hydrogen. In making hydrogen all you are doing is converting one energy source into a different energy source. While that is good, it does not qualify as creating a NEW energy source.
Now if you use a real sharp pencil you might also discover that electric power plants cannot use hydrogen to make electricity because it would be far too expensive. No, they would be using coal, or gas, or gasoline, or oil, or wood to make affordable electrical energy that someone else can use to make hydrogen.
So all we have done is increase the need for electricity enormously and we still have all the potential for polution we had before all our vehicles started using hydrogen.
