Table TS.10. Range of total costs for CO2 capture, transport and geological storage based on current technology for new power plants using bituminous coal or natural gas

Power plant performance and cost parametersa Pulverized coal power plant Natural gas combined cycle power plant Integrated coal gasification combined cycle power plant
a All changes are relative to a similar (reference) plant without CCS. See Table TS.3 for details of assumptions underlying reported cost ranges.
b Capture costs based on ranges from Table TS.3; transport costs range from 0-5 US$/tCO2; geological storage cost ranges from 0.6-8.3 US$/tCO2.
c Same capture and transport costs as above; Net storage costs for EOR range from -10 to -16 US$/tCO2 (based on pre-2003 oil prices of 15-20 US$ per barrel).
