Technically correct, but scientifically impractical. From a thermodynamics perspective it makes no sense. We will still have oil interests, because you are sitting on an oil chair, dress in oil clothes, and sleep in an oil bed.
Well hydrogen extraction from gasoline/natural gas is possible today and resonably practical.
Yes it can be done. The problem is that if you take oil and extract the hydrogen from it, you consume energy. No process is 100% efficient, so conversion would be less efficient than straight combustion. There is the possibility that there is a catalyst that is more efficient for doing this than straight combustion, but I havent kept up with petroleum science as much as perhaps I ought.
Pay more attention. Combustion is terribly inneffecient because it produces more heat than usuable power. It does not take much to be more efficent than combustion. And you do not get hydrogen for free anywhere.
Interesting. Cant seem to find specifics though. Some vague references about oil to hydrogen conversion, but nothing about the relative efficencies. What kind of process are they using? Perhaps you can provide technical links with specifics, taking into account the power costs of conversion added to the inefficencies of producing energy from fuel cells. I know you can do this because you pay attention.
Linkage.
Good! Almost there. Now the article you cite talks about reforming with methanol. All we have to do is dig more methanol wells... No wait. Drat! Seems there is at least one more - step gotta make methanol... Oh there is infrastructure, fuel cell cost, still have CO2 production.
By the time you are done, I doubt you will have a significant difference in OVERALL efficiency between fuel cells powered this way and petroleum based engines, especially if you consider the possible improvements in diesel technology.
All of the this may sound like I am against fuel cells. You would be mistaken to believe so. I think much more should be spent in alternative energy sources. Unfortunately, we would rather put ourselves in jeopardy and rely on oil than spend 1/2 of what it will cost to rebuild NY in R&D. I have often referred to the harnessing of wave energy for electrical power generation. It is a commercial success in the UK. That power could be used to generate electricity to break down water. Non polluting power as long as there are waves. Most of you are too young to remember the oil embargo. That was a treat. Literally riots in the street. Did we learn our lesson? Nope. It's about time we did.
