Answer 1

Quite simply, liquid coal produces about twice the greenhouse gas emissions as gasoline. It also involves the rather destructive and environmentally damaging process of mining coal.

Answer 2

The big advantage with the "liquid coal" process is that it becomes much easier to extract the harmful chemicals/elements that are given off from coal burning. In proposed coal-fired plants, the carbon dioxide will be sequested underground and the mercury, sulfur and other chemicals will also be extracted. All that is left is an inert slag. So, you kill two birds with one stone, by burning coal by-products for electricity and also extracting mercury and sulfur for use in industry.

The disadvantages are that carbon dioxide sequestering cannot be done forever... eventually we will run out of room to put the stuff. Also, the new liquid coal plants will not be commonplace for some time to come. There is still the environmental harm done by extensive coal mining operations. Finally, the costs are expected to be somewhat higher for these newer plants.

So, it is not perfect, but if you want a temporary fix that will keep your lights on and also be a bit easier on the environment, it might do the trick.

Answer 3

The only disadvantage is that it's still a fossil fuel.

Our country has twice the coal as saudi araba has oil. This scares those who's true agenda is to eliminate all fossil fuels.

To the believers, anything that's a fossil fuel is bad, no matter how much it helps reduce foreign oil consumption or reduces co2.
