At a plausible GHG emissions price of $ 50 / t CO2eq under a future US carbon mitigation policy, such co-production systems competing as power suppliers would be able to provide low - GHG -
emitting synthetic fuels at the same unit cost as for coal
synfuels characterized by ten times the GHG emission rate that are produced in plants having three times the
synfuel output capacity and requiring twice the total capital investment.
