Different methods of C02 Capture from natural gas power plants and its economic feasibility by CDM

Considering the dramatic increase of greenhouse gases, especially carbon dioxide, reduction of these gases seems necessary to combat global warming. Fossil fuel power plants are one of the main sources of carbon dioxide emission. In this paper, two methods of C02 capture from natural gas power plants (steam cycles and combined cycles) are mentioned, and the effect of the capture systems on the performance and costs of power plants are assessed. Comparing the results, natural gas combined cycle (NGCC) which uses Amine solvents for C02 capture is mentioned as the best choice. However, C02 capture is a cost and energy consuming process. Therefore, for compensating these additional costs carbon dioxide revenue of about 40$/ton is estimated which can be provided by Clean Development Mechanism (CDM).
