FIGURE 5.6 Cost of alternative liquid fuels produced from coal, biomass, or coal and biomass with a $50/tonne CO2price. Negative cost elements must be subtracted from the positive elements; the number at the top of each bar indicates the net costs.
Note: BTL = biomass-to-liquid fuel; CBFT = coal-and-biomass-to-liquid fuel, Fischer-Tropsch; CBMTG = coal-and-biomass-to-liquid fuel, methanol-to-gasoline; CCS = carbon capture and storage; CFT = coal-to-liquid fuel, Fischer-Tropsch; CMTG = coal-to-liquid fuel, methanol-to-gasoline.
life cycle, the inclusion of a carbon price reduces the pathway’s total cost of producing liquid fuel. Note that these estimates are all based on costs for small gasification units operating at a feed rate of 4,000 dry tons per day. If larger units were deployed in regions where potential biomass availability is large—for example, 10,000 dry tons per day—the result could be significantly lower costs.
