To be honest the fuels nowadays are very clean to what they used to be, i have recently been doing some work for shell and they say that the emitted CO2 from our cars is peanuts and nothing like the figures quoted.
It is just another hidden tax, plus there is still another 40-50 years of oil in the north sea which is as much as BP and shell thought there was back in the sixties.
There is also a hell of a lot of oil out in canada, Kazakhstan, azerbaijan and the russian federation. let alone china etc etc, so it is very unlikely that we will be seeing any new fuels developed by the big oil companies in the near future as they are investing heavily out in Kaz and russia right now.
By the way if any engineers on here fancy some work in kazakhstan let me know, its tax free too.
