Abstract
Coal is the main fossil fuel used worldwide for the generation of electric power due to its low cost and high availability of reserves, and therefore must still be used for some hundred years as the main energy resource. The environmental impacts associated with the emission of pollutants from the process are of great relevance, the main pollutants being SOx, NOx, particulate matter, and CO2. CO2 emissions represent a major problem in planetary dimensions, given their influence on climate change. To glimpse a reduction of carbon dioxide emissions through changes in the fuel does not show as a viable alternative for most cases, thus, the optimization of the thermal conversion process by increased efficiency of coal-fired power plants has been studied, and technologies have already been applied. The study aims to quantify CO2 emissions in both specific and large-scale terms, considering the use of different technologies, through the construction of 3 different scenarios with the hypothesis of using different technologies in the coal-fired generation units. The results indicate that the modernization of the global thermal coal park would provide a significant reduction of emissions, allowing the promotion of a low carbon matrix, without the need to abandon the use of mineral coal as a source for electricity generation.
