Abstract: It has been regarded as a necessary technical route for retrofitting carbon capture, utilization and storage（CCUS） to coal-fired power plants, which will mitigate CO2 emission to satisfy the requirement of 2℃ targets. As coal electricity dominates China’s electricity energy system, it is of great significance to evaluate the technical feasibility of implementing retrofitting CCUS to existing coal-fired power plants. In this paper, an evaluation method for retrofitting CCUS to coal-fired power plants at the enterprise level was developed, the main evaluation basis and core parameters were proposed. And with the actual operation situation of coal-fired power plants in former Shenhua Group as the sample, the suitability evaluation for retrofitting full chain CCUS to coal-fired power plants was finished. The results show that about 55.89 trillion watt capacity of coal-fired power units（77% of the total installed capacity） in former Shenhua Group have the foundations to add carbon capture equipment, in which about 44.14 trillion watt capacity（about 79% of the total installed capacity） are feasible for CCUS retrofits（only considering geological storage options of CO2-EOR and CO2-EWR）. In summary, about 60% of the total installed capacity in former Shenhua Group is feasible of deploying the CCUS retrofits. This research builds a solid foundation to policy-decision makers and enterprise managers on the large-scale development of CCUS technologies at nation land enterprises scale in the future.
