Hydrogen to make Hydrogen??

Is it Possible to a run a Plant on Hydrogen to Produce Hydrogen and can Hydrogen if Produced cheaply enough run say a Power station that will heat and power all our homes, I know cars can run on a Hydrogen cell which is environmentally clean so why not power stations....and if this was possible would there be enough raw material on the planet to produce a hydrogen based clean energy source for the next several hundred years...our only use for Oil after that would be as a Lubricant....are we going to be saved by a Hydrogen revolution or are we already doomed to follow the Dodo to extinction by the year 2050???
