It has to be an energy source that is non-polluting as well.

It can definitely be done but the cost is still much greater then relying on refined crude oil. Read this months Scientific American for more information.

To begin with, I confess that I don't know the direct answer to your query. However your question suggests that gasification would help to reduce pollution. If this is the background to your question, I must make the point that no benefit would accrue. Coal is almost pure carbon and if 'gasified' to carbon monoxide the produced gas would itself burn to carbon dioxide and so pollute. It is true that 'water-gas' i.e. hydrogen can be obtained by blowing steam over red-hot coke, but the energy required by its production exceeds that given out when it is burned.

Really slow because there is little federal money for research. Let's see, little Bush is an oil person (I can't honor him by saying he's a oil MAN). Therefore, we can see why there is little federal money for research into coal gassification and others.
