From researchers at the University of Padova, Italy, regarding CTL processes:
"As a second possibility, the same gasifier−combustor scheme is coupled with a coal-to-liquid (CTL) process to convert the syngas into synthetic fuels by a FT reactor. It is shown that, if compared with a conventional CTL plant, the mass yield of liquid synthetic fuel is increased by 39.4%, the CO2 emissions per unit of liquid fuel are decreased by 31.9% and energy efficiency increases by 71.1%."
Point is: CTL can help us reduce CO2 emissions to begin with. And, as earlier noted, once the CO2 is generated, there are ways we can not just capture the gas, but use it constructively. We should try to view it as a useful by-product.
