碳中和背景下煤电转型关键技术研究与展望

In view of high carbon emission of coal power, combined with the transformation ideas of clean, flexible, low-carbon emission and intelligent development of coal power, the typical technologies of coal power transformation were explored from five different dimensions including efficient and flexible transformation etc. The carbon reduction potential from 2030 to 2060 was quantified with six typical low-carbon technologies. The carbon reduction cost, carbon reduction potential, penetration rate, clean contribution, application prospect and maturity were selected as the major criteria to study and judge the development trend of typical technologies, which would provide a certain reference for the research on the transformation path of coal power under the "carbon peak and carbon neutrality" goals. Results show that in the short term, it is suitable to continuously promote the flexible peak load regulation, energy-saving and efficiency-enhancing upgrade, and application of high-efficiency technology; in the medium and long-term period, the major measures are high-efficiency generation technology, and the application of fuel substitution technology is gradually expanding and complementing with carbon capture, utilization and storage (CCUS) to achieve near-zero emissions of the units.
