摘要

This paper compares the financial viability of private sector investment in a coal power plant with carbon capture and geothermal power plant based on long-term contract of Power Purchase Agreement (PPA). Based on the project cash flow analysis, it is found that investing in a coal power plant that must install carbon capture is only financially viable if there is demand for CO2 from EOR market. Financial performance of a coal-fired power plant with carbon capture installation is significantly improved when there is demand for captured CO2 to be utilised for EOR in oil production. Private investment in geothermal power plant offers more favorable investment returns than investing in coal-fired power plant with carbon capture. The private sector investment in power generation may choose to invest more in renewable energy power plants such as geothermal power that offer a more attractive return on investment than investing in clean coal technology such as coal-fired power plant with carbon capture.
