“…Also, under the same research programme, attempt was made by Rolls Royce International Combustion Ltd. to demonstrate the technical feasibility of this technology in a 35 MWth burner [10]. Around mid-1990s, a research consortium led by IHI funded by NEDO did the first pilot scale studies in Japan [11][12][13][14]. During the later part of the 1990s, CANMET [15][16][17] and a research consortium led by Air Liquide [18,19] did further pilot scale studies on this aspect of combustion.…”

“…IHI in Japan [3], Chalmers University of Technology in Sweden [4], ALSTOM in America [5], Argonne National Laboratory in America [6], CANMET in Canada [7] and EDF in France [8] have all carried out techno-economic evaluations of the oxy-combustion technology. The results of IHI [3] show that the efficiency of the oxy-combustion power plant (1000 MW) decreases 10.5%; the results from Chalmers University of Technology [4] show that the efficiency of the oxy-combustion power plant (865 MW) decreases 9.1%, the CO 2 avoidance cost is $26/t and the cost of electricity is $64.3/kW; the results of ALSTOM [5] show that the CO 2 avoidance cost of the oxy-combustion power plant (450 MW) is $42/t and the unit investment cost is $823/kW; the results of Argonne National Laboratory [6] show that the CO 2 avoidance cost is $34/t; the results of CANMET [7] show that the CO 2 avoidance cost of the oxy-combustion power plant (400 MW) is $35/t, the cost of electricity increases 20%-30% and the unit investment cost is $791/kW; the results of EDF [8] show that the efficiency of the oxycombustion power plant (1200 MW) decreases 10%, the investment cost increases 69%, the cost of electricity increases 48% and the CO 2 avoidance cost of the oxy-combustion system is 29% lower than that of the MEA scrubbing system. These results can be summarized as: if conventional coal-fired power plants are retrofitted to be oxy-combustion power plants, the net power output will decrease by about 25%, the cost of electricity will increase by 30%-50%, the CO 2 avoidance cost is about $30/t and about 85% CO 2 can be captured.…”

Increasing attention is being paid to the oxy-combustion technique of coal-fired power plants because CO 2 produced from fossil fuel combustion can be captured and sequestrated by it. However, there are many questions about the economic properties of the oxy-combustion technique. In this paper, a detailed techno-economic evaluation study was performed on three typical power plants (2 × 300 MW subcritical, 2 × 600 MW supercritical, 2 × 1000 MW ultra supercritical), as conventional air fired and oxycombustion options in China, by utilizing the authoritative data published in 2010 for the design of coal-fired power plants. Techno-economic evaluation models were set up and costs of electricity generation, CO 2 avoidance costs as well as CO 2 capture costs, were calculated. Moreover, the effects of CO 2 tax and CO 2 sale price on the economic characteristics of oxy-combustion power plants were also considered. Finally, a sensitivity analysis for parameters such as coal sample, coal price, air separation unit price, flue gas treatment unit price, CO 2 capture efficiency, as well as the air excess factor was conducted. The results revealed that: (1) because the oxy-combustion technique has advantages in thermal efficiency, desulfurization efficiency and denitration efficiency, oxy-combustion power plants will reach the economic properties of conventional air fired power plants if, (a) the CO 2 emission is taxed and the high purity CO 2 product can be sold, or (b) there are some policy preferences in financing and coal price for oxy-combustion power plants, or (c) the power consumption and cost of air separation units and flue gas treatment units can be reduced; (2) from subcritical plants to supercritical and finally ultra-supercritical plants, the economics are improving, regardless of whether they are conventional air fired power plants or oxy-combustion power plants.oxy-combustion, CO 2 emission control, techno-economics, sensitivity analysis, CO 2 tax, CO 2 sale, cost of electricity Citation:Xiong J, Zhao H B, Zheng C G.

“…A power plant adopting this type of CO 2 capturing technology utilizes oxygen and circulated flue gas as oxidant to burn fuel [13]. CO 2 gas can be directly captured since the flue gas consists of only CO 2 and steam.…”
