Actually, I believe the funding stated the source of Hydrodgen must be natural gas, not oil...
There may still be advantages to doing this...if the fossil fuel is broken down in a factory it would be easier to control greenhouse gas emissions...
Even options like ethanol have serious issues. Politicians in the midwest love it because it's good for the local economy...but it requires tremendous amounts of energy to produce.
In the end I've seen little that indicates which alternative sources really provide a significant "net" gain when all the complexities are accounted for.
