Perhaps you should read this pre-invasion Forbes' article "Hitting OPEC by way of Iraq". This is the thinking that got us into the Iraq invasion in the first place:

"Iraq will require a minimum of $30 billion in investments to develop its oil industry," says Chalabi. "With that, it could reach a production rate of 7 million to 8 million barrels a day within four or five years."
That's close to what Saudi Arabia produces today. With such a huge new supply of oil on the world market, prices could plummet.

I agree that things haven't exactly worked out the way the Neocon's wanted, but you should read the entire article to understand the potential oil that Iraq could provide. There's also that pesky oil law that the Iraqi government has to sign off on.
As for Hydrogen or hydrogen fuel cells, I would agree that hydrogen is a MEANS FOR STORAGE of energy, not a source of energy. I never said that we had to somehow mine hydrogen. There are, however, tremendous alternative energy sources which could be used to create hydrogen energy.
