If you can get a high pressure pump at the right price, its very economical over here. natural gas is less than 1/4 the price of petrol or diesel.
I think Austrailia exports natural gas. There were plans for super cooled or LNG tankers from Austrailia to the West Coast. Some concerns with Terrorism and stuff.
I did see an article on CNN. It was on Butanol. It is a more complex form of alcohol, than ethanol or methanol. It is suppose to be a direct replacement for gas. So no special mods or special needs to transport it. It dealt with gene splicing on bacteria. Some bateria produce it naturally, but they don't digest cellulose. Other simular bacteria digest cellulose, but produce something else.
So, relatively the biofuels are still in their infancy. It seems the big push is to transition from food/grain sources to waste sources. At what price level that is economically feasable? I'd say somewhere over $100/barrel.
