admin Hydrogen fuel cell cars are expensive and impractical. So why would we even consider them? With gasoline prices well over $4 per gallon and reduction of CO2 emissions a priority, all alternative fuels and future car technologies are getting a closer scrutiny these days. Not only that, if a proper infrastructure was created, Hydrogen could very well be the world’s next propulsion fuel. Its cheap and abundant…so what are we waiting for?

Hi there, good to hear you're trying to help reduce carbon and pollution emissions. Despite the nay-sayers, there are solutions. Might cost a bit though!
Clean Technology Center Collaborative do a conversion kit – which actually works – you can see pictures of converted cars here: http://www.shfca.org.uk/article_image_list.fcm?subsite=6942§ion=46
However, you might find that selling the Jeep and buying a hybrid 4X4 is a more economic (and environmentally friendly) option.
As for it being 50 years before hydrogen-fuelled engines, fuel cells and hydrogen fuel is available – don't believe that! Have a look at "H2ICE" in Google – hydrogen internal combustion engine. Also have a look at the 'Hydrogen Highway' projects in the US, Canada and Germany.
So, short story: you're moving in the right direction, but probably trying to go about things in the most difficult possible way. Hybrids are probably the way to go for now – maybe that new Lexus RX400h or one of the new Ford SUVs coming out soon?
