It's quite common to see claims that coal-to-liquids is capable of replacing the USA's imports of oil.
- Net US imports for 2009 ran about 9.7 million bbl/day.
- At 6.1 GJ/bbl this is 21.6 EJ (20.5 quads) per year.
- If refineries convert crude to product at 90% and CTL operates at 45% efficiency, it would take 43.2 EJ (41.0 quads) per year of coal to replace oil imports.
- The USA only produced 19.8 quads of coal in 2009.
Using CTL to replace oil imports would require more than tripling coal production. This is Not. Gonna. Happen. PEVs can happen, and we should make them happen just as fast as we humanly can.
