Gasification of coal is easy and can often be done in situ without extracting the coal from the ground. The least expensive method of extracting hydrogen from coal is twice as expensive as producing hydrogen from natural gas. This relationship can be used as a reliable benchmark ratio for determining the production cost for gasoline etc. Generally the higher the ratio of hydrogens to carbon, the higher the value, the lower the cost of conversion, and of course the less the greenhouse gas problem. Refineries like most used by Chevron do something quite similar. Rather than distill oil, they heat the oil to much higher temperatures with catalysts and additional hydrogen from natural gas to produce "synthetic" uniform molecules of higher hydrogen ratio gasoline and other fuels. The Australian Coal Association covers some of these issues. In particular the new production of "clean coal" created by pre-treating the coal with acid and alkali's to remove other minerals. australiancoal.com.au .
