It seems to me that the conclusions are stilted toward the plug in hybrids by the fact that they are assuming an efficiency of 120 miles per gallon equivalent (3.5 mi/kWh) vs. 34 MPG for a gasoline powered sedan. Further, the assumed electric car only has a range of only 60 miles. If these huge differences in vehicle types were normalized, I'd wager that CTL would come out significantly better than the electric option.
The whole report is just skewed for some reason. They don’t even mention diesel fuel being made from coal, nor do the bring up the subject of a diesel-hybrid combo.........
