This paper examines a novel integration mechanism of solar energy into a 300 MW coal-fired power plant to improve the performance and techno-economic feasibility of the proposed system while decreasing pollutant emissions by coal consumption reduction.
For comparison, the emission and ecological footprints of coal power generation system is calculated to evaluate the performance of SPPG system. For the life-cycled assessment, a clean coal-fired project with 2 × 1000 MW ultra-supercritical power plant is used for the case study (Yu et al., 2017).
This study aims to fill this gap by providing a detailed comparative analysis of the life cycle assessment and ecological footprints of SPPG and coal power generation. The significance of this research lies in its potential to inform policymakers and stakeholders about the environmental implications of energy choices.
The pairing of coal and solar energy may seem an unlikely combination, but under the appropriate circumstances, could offer an elegant solution to combining the reliability and cost-effectiveness of large-scale coal-fired generation with an emissions-free form of renewable energy.
The hybridization of solar energy with a coal-fired power plant is a promising way to reduce the numerous environmental issues related to a coal-based power generation sector.

Coal use for power generation in China
Coal holds dominant position in China''s primary energy mix, and roughly 45% of China''s coal consumption is used for power generation. In this paper, we study the prospective of coal used for power generation in China into 2030 by testing three interrelated factors, namely electricity demand, fuel mix and generation efficiency of coal power.
