| Summary/Abstract |
This study examines the effects of the inclusion of the co-benefits on the potential installed capacity of carbon dioxide capture and storage (CCS) projects with a linear programming model by the clean development mechanism (CDM) in India's power sector. It is investigated how different marginal damage costs of air pollutants affect the potential installed capacity of CCS projects in the CDM with a scenario analysis. Three results are found from this analysis. First, large quantity of IGCC with CCS becomes realizable when the certified emission reduction (CER) prices are above US$56/tCO2 in the integrated Northern, Eastern, Western, and North-Eastern regional grids (NEWNE) and above US $49/tCO2 in the Southern grid. Second, including co-benefits contributes to decrease CO2 emissions and air pollutants with introduction of IGCC with CCS in the CDM at lower CER prices. Third, the effects of the co-benefits are limited in the case of CCS because CCS reduces larger amount of CO2 emissions than that of air pollutants. Total marginal damage costs of air pollutants of US$250/t and US$200/t lead to CER prices of US$1/tCO2 reduction in the NEWNE grid and the Southern grid.

| Summary/Abstract |
Coal power coupled with Carbon [Dioxide] Capture and Storage (CCS), and Concentrating Solar Power (CSP) technologies are often included in the portfolio of climate change mitigation options intended to decarbonize electricity systems. Both of these technologies can provide baseload electricity, are in early stages of maturity, and have benefits, costs, and obstacles. We compare and contrast CCS applied to coal-fired power plants with CSP. At present, both technologies are more expensive than existing electricity-generating options, but costs should decrease with large-scale deployment, especially in the case of CSP. For CCS, technological challenges still remain, storage risks must be clarified, and regulatory and legal uncertainties remain. For CSP, current challenges include electricity transmission and business models for a rapid and extensive expansion of high-voltage transmission lines. The need for international cooperation may impede CSP expansion in Europe.
