When concerted actions start to be taken to achieve this goal, fossil generating stations, as large point sources of CO2, may be required to make disproportionately large emission reductions because doing so will be cost effective. At present natural gas combined cycle (NGCC) is the technology of choice for providing new electric generating capacity in the U.S. for reasons that include environmental performance, thermal efficiency, high availability compared to renewables, and relatively low capital cost. Relatively low specific carbon emissions (kg C or kg CO2/kWh) compared to coal generators is another attraction of NGCC. Yet NGCC cannot be the only response of the electric power industry to the challenge of global warming even if affordable supplies of natural gas were assured into the indefinite future. Climate modelers estimate that upwards of 60% reduction in greenhouse gas emissions from current levels will be needed to stabilize atmospheric composition. That is a greater reduction than could be achieved even if all coal -fired units were replaced with state-of-art NGCC. This paper invites serious consideration of fossil fueled electricity generation technologies that capture nominally 90% of CO2 emissions and use the CO2 to conduct enhanced oil recovery. Carbon sequestration of this kind represents a fundamentally different approach to reducing carbon emissions that has potential not less than traditional approaches such as improvement of thermal efficiency of generation, improvement of end use efficiency, and use of renewables. There is no immediate prospect for commercial deployment of fossil generation with CO2 capture and sequestration, however, because with no value assigned to reducing carbon emissions, such processes are more expensive than conventional fossil generation. One approach to overcoming this problem is to investigate use of a carbon tax or carbon emission cap. This study takes a different approach. It considers how the economics of natural gas- and coal-based generation with carbon capture would fare if a market for the collected CO2 is assured for practice of EOR. Coal-based IGCC with CO2 capture and sequestration would yield only one fifth the specific carbon emissions (kg C or kg CO2 /kWh) as would state-of-art NGCC. California appears to be a good venue for consideration of IGCC+S: there is need for additional generating capacity and an unserved market for CO2 that could be used to conduct enhanced oil recovery. In this paper, a probabilistic analysis is conducted to determine Required Selling Price of Electricity (RSPOE) and expected rate of return on common stock equity for three fossil generating technologies: NGCC, NGCC+S (NGCC with capture and sequestration), and IGCC+S. Variables treated probabilistically are the costs of natural gas and coal fuels, and the values of electricity and CO2 products. Predictions of prices prepared by the Energy Information Agency are used together with measures of price variability based on historic price fluctuations. Installation of new generating plant is assumed to occur in 2010 and operate for a 20 year book life to 2030. It is shown that when CO2 can be sold at historically realized prices for use in enhanced oil recovery (EOR), IGCC+S is expected to be profitable with no subsidy for avoidance of CO2 emissions. Expected profitability of NGCC is greater than that of IGCC+S, but so is the uncertainty of RSPOE and expected rate of return on common stock equity, due principally to uncertainty of natural gas price. NGCC+S exhibits both a higher RSPOE and higher uncertainty of RSPOE than either of the other technologies.
