Abstract Oxy‐fuel combustion is one of the most promising technologies for large‐scale CO 2 capture and storage in power plants. This flexible technology can be used in new power plants and in existing plant retrofits, with no technological barriers to its implementation. In this paper, economic research was conducted into a 200 MW power plant using oxy‐fuel combustion. The paper has important implications for the large‐scale application of oxy‐fuel combustion. Different combustion modes (conventional combustion, and oxy‐fuel combustion including dry and wet recycling) were considered. Several factors were taken into account, including the operation parameters of equipment and the parameters of the flue gas. The dynamic investment cost, the annual cost, the non‐taxable electricity price, energy consumption, and other data were obtained. It was concluded that, with a CO 2 capture efficiency of 90%, the CO 2 emission reduction cost of 200 MW under an oxy‐fuel combustion system is about 413 yuan/t. This research can provide accurate cost information for specific projects, and provide economic and cost references for other oxy‐fuel combustion projects. © 2018 Society of Chemical Industry and John Wiley & Sons, Ltd.
