There are already some ways of producing artificial fossil fuels. There was this very promising method that involved special enzymes, which were found in the amazonian jungles and were responsible for decomposing the huge amounts of leaf mass that fall down from the trees. These enzymes could in theory be used to create artificial fossil fuel by sped up rotting of bio masses and such, and it was later even proven practically that this works. They were looking into ways of incorporating it into the industry, but I guess there's not much demand yet.
Still every such project progresses with baby steps, and the big governments at their best aren't too helpful.
