Well, the traditional way of extracting oil is pumping. Typical process will be pumping, transporataion, refining, and more transportation. That will weild an Energetic Return on Energetic Investment (EROEI) of about 30 to 1. (1 invested unit of energy for 30 units of energy gained)
To give you an example, when they extract oil from the oil sands in northern alberta, the end-product has a 2 to 1 EROEI ratio, that's 1 unit of energy invested for every 2 units gained.
Hydrogen, on the other hand, takes *more* energy to invest that what is gained. It's got a *negative* EROEI. And that's without counting the energetic costs of transporting the hydrogen, of putting it in a transportable form, of distributing it, of mass-producing the hydrogen equipment, of the hydrogen fuel cells which, for the moment, cost about 1 million $ a piece, and the high dangers of the highly explosive hydrogen bomb you'd have in every car.
With oil, you extract it as it is in the earth, so at a very loc energetic cost, and when reffined, it will produce energy. Hydrogen will take energy to bring in a consumable form, and weild less energy than it took to make.
I'll try a money-related analogy. You need money. Money is like energy. You can either get your money from right on your nightsand (it's easy to access, it doesn't cost you much to access it), or you can withdraw from the atm (like the oil sands, it takes more moeny, but you still withdraw more than you pay in transaction fee).
Hydrogen is like having to pay - say... - 150% of the amount you withdraw in transaction fees, whatever the amount you withdraw. So for every 20$ you withdraw, you give the bank 30$!
...
Hmm, do you feel I've answered your question ok? Don't hesitate to ask more if I wasn't clear enough, or didn't answer exactly what you wanted to know... :)
