[liquid fuels from coal] could be economic if oil prices stay consistently above US$25-40 a barrel. Oil currently costs double that, and briefly touched $100 a barrel last month...-- from Alarm over new oil-from-coal plans.
Of the 30 or so large-scale coal-to-liquids plants being worked on around the world, only one in Australia plans to conduct a carbon capture trial.
Even capturing the carbon may not solve the problem. An analysis by the [US DOE] last year said that liquid fuels from coal, even with carbon capture and storage employed, would still produce at least 20% more carbon dioxide than petrol and diesel made from oil.
But Krugman is sceptical: things like coal-to-oil "always fall short of expectations", he thinks. Really?
