Abstract

The power industry is a major contributor to carbon dioxide (CO₂) emission, which accounting for 40% of total domestic carbon emission. Based on the carbon emission accounting method, this paper conducts carbon emission accounting for a number of power generation enterprises, analyses and concludes that the carbon quota allocation is being tightened year by year, proposed countermeasures and emission reduction routes in terms of carbon asset management and carbon reduction technology research. According to the actual situation of a coal-fired power plant in Anhui province, different carbon reduction routes are developed, among which photovoltaic power generation project has the most impressive economic benefits, but carbon capture project has the largest carbon reduction benefits. Under the premise of similar initial investment between the two projects, the carbon reduction brought by the latter is 5 times that of the former. It is suggested to choose the “new energy power generation+carbon capture and utilization” coupling technical route, which can improve the flexible operation of thermal power units and the absorption rate of new energy, and achieve efficient decarbonization. It provides a sustainable development technical route with both economic and environmental benefits for the low-carbon process.
