Abstract: A life cycle assessment was conducted out to estimate the environmental impact of three coal-based electricity generation scenarios commonly used or encouraged in China, namely, sub-critical technology (300 MW), supercritical technology (600 MW), and ultra-supercritical technology (1000 MW). Compared with other scenarios, the ultra-supercritical technology accounted for significantly environmental benefits in most categories, except in the natural land occupation category because of the landfill disposal of coal ash. Optimizing net coal consumption efficiency, reusing coal ash as building material, increasing desulfurization and denitrization system efficiency, and decreasing the road transport distance from coal buyer to supplier are key factors in reducing the overall environmental impact of electricity generation.
