CCUS technology is crucial for coal power plants in China to maintain existing production structure and achieve near-zero carbon emissions under the dominance of coal in the current energy structure. Government incentives play a significant role in promoting investment in CCUS technology, with a subsidy ratio exceeding 0.33 encouraging immediate investment in coal-fired plants.
Carbon capture, carbon utilization and storage (CCUS) technology is an important potential technical support for coal power plants to maintain existing production structure while simultaneously achieving near-zero carbon emissions with the current energy structure in China being dominated by coal. However, CCUS technology is still at the early demonstration stage, and there are many uncertainties in the carbon trading market, technology and policy incentives that the traditional method is no longer able to handle. Based on the binomial tree real option model, this paper establishes a CCUS technology investment evaluation model that incorporates the uncertainties with carbon price, government subsidy, technological progress and carbon dioxide utilization ratios into the model, and investigates the influence of government incentive on CCUS technology investment in two scenarios in China. The numerical results in case study show that (1) If the subsidy is too low, no matter how high the lower limit of carbon price is set, enterprises will not invest. (2) When the proportion of government subsidy exceeds 0.33, a specific and accurate minimum carbon price is given to promote coal-fired plants immediate investment in CCUS technology based on the model. (3) Only the government subsidies cannot stimulate CCUS investment at this demonstration stage. These findings provide a reference for public policy decision-making and promotes the development and large-scale deployment of CCUS technology in China. [GRAPHICS] .
