Gas to liquids cost Compared to conventional gas-to-liquids (GTL using natural gas), making liquids using syngas from underground coal gassification (UCG) is much cheaper. With UCG syngas there is no need for the steam reforming step that is 50% of GTL cost. This is a HUGE advantage of UCG-CTL. Not only do you get a cheap source of gas, but the gas is already close to the right composition for Fischer-Tropsch. But even with these advantages, a UCG coal to liquids plant would not be cheap. This report from the SyngasRefiner suggests capex cost of $40K b/d for a UCG-CTL plant: $4 billion for a 100 k b/d plant. see page 11 eia.doe.gov
