Way to go Iceland. Too bad every country cannot do this.

Good for Iceland

Except too bad hydrogen fuel cells don't really work, not yet at least. Hydrogen fuel cell engines have a life expectancy of
200 hours, so after every 200 hours of use you have to get a new engine.
It also takes 1113 gallons of gas hydrogen to equal the energy of 1 gallon of gasoline.

Swearbear do you have a source other then a message group for those figures?

The article on the message group is from the
EV World magazine, as you can see.
Michael Ruppert also mentioned this in his docu "Denial Stops Here."


Kay thanks, I just looked at the URL so my mistake I knew that the comparison between gas and h2 was bad, I just didn't know it was that bad.

There's an interesting document on hydrogen myths here:


rmi.org (pdf)

Crude oil can be more efficiently converted into delivered gasoline than can natural gas into delivered hydrogen.12 But that’s a red herring: the difference is far more than offset by the hydrogen’s 2–3-fold higher efficiency in running a fuel-cell car than gasoline’s in running an enginedriven car. Using Japanese round numbers from Toyota, 88% of oil at the wellhead ends up as gasoline in your tank, and then 16% of that gasoline energy reaches the wheels of your typical modern car, so the well-to-wheels efficiency is 14%. A gasoline-fueled hybrid-electric car like the 2002 Toyota Prius nearly doubles the gasoline-to-wheels efficiency from 16% to 30% and the overall well-to-wheels efficiency from 14% to 26%. But locally reforming natural gas can deliver 70% of the gas’s wellhead energy into the car’s compressed-hydrogen tank. That “meager” conversion efficiency is then more than offset by an advanced fuel-cell drivesystem’s superior 60% efficiency in converting that hydrogen energy into traction, for an overall well-towheels efficiency of 42%. That’s three times higher than the normal gasoline-engine car’s, or 1.5 times higher than the gasoline-hybrid-electric car’s.47 This helps explain why most automakers see today’s gasoline-hybrid cars as a stepping-stone to their ultimate goal — direct-hydrogen fuel-cell cars.

I really doubt that because the Honda FCX gets over 50mpg on hydrogen.

Also, the record holder for the most fuel efficient vehicle is a hydrogen car that got over 12 thousand miles per gallon.

That would be compressed hydrogen, which is 10 times more flammable and 20 times more explosive than gasoline.
Do a crash test on that and you might have some really nice fireworks!
