John, Colchester asked:
If we didnít burn this thick sulphurous diesel in the marine engines that weíve got, what could we actually do with it?
We put this question to Tristan Smith from UCL...
I think thatís a really good question. I mean, we could build more roads I suppose, but that doesnít really sound like a very good thing to do so. What the refinery would actually do with this by-product of the refining process of the heavy crude is not particular clear and I think itís something that they would probably have concerns about too. Whoís going to actually take the stuff off their hands if the ships arenít consuming it themselves. The ships are basically the last industry thatís still using it as a fuel and there are no sort of major takers left in the world at the moment.
