Abstract: Under the goal of "double carbon", coal-fired power generation is gradually transitioning from the main energy to the underlying energy. Coal-fired power generation technology is constantly developing in various aspects, such as clean coal treatment, high-efficiency power generation and low-carbon treatment of emissions. At the same time, it is also transitioning to in-depth peak shaving auxiliary services and "coal +" coupled power generation. It is therefore of great significance to explore efficient and clean advanced coal-fired power generation technologies. This paper analyzes the research status of clean coal utilization technologies such as supercritical coal gasification, supercritical coal liquefaction and supercritical coal water oxidation, discusses the technical characteristics of advanced coal-fired low-carbon power generation modes such as supercritical coal water oxidation thermal power generation technology, supercritical CO2 power cycle technology, integrated coal gasification combined cycle technology and ultra supercritical circulating fluidized bed technology, and explores the development trend of carbon capture utilization and storage technology. At the same time, the transition direction of clean coal power generation technology is prospected, which can provide development ideas for the realization of the goal of carbon peaking and carbon neutrality.

Key words: carbon peaking, carbon neutrality, advanced power generation technology, clean coal utilization, coal water oxidation, carbon capture
