Outline
The ecological, environmental, and social issues caused by greenhouse gas emissions, mainly CO2, are receiving increasing attentions and concerns from human beings. At present, the carbon sequestration technology using flue gas from thermal power plants as CO2 source is still in the pilot and industrial development stage, but there is no standardized methodology and accounting method for carbon reduction benefits of the carbon sequestration process. Combining the industrialization practice of the first domestic “CCUS Technology Research and Demonstration Project for Carbon Dioxide Chemical Chain Mineralization Utilization in Thermal Power Plants” constructed and operated by a power plant, the carbon emission reduction benefits of the CCUS technology pathway for chemical chain mineralization utilization were calculated and evaluated using the life cycle assessment (LCA) carbon emission factor method. The annual CO2 processing capacity of the above demonstration project is 1 364.56 tons, which can achieve a net reduction of 708.12 tons of CO2, reaching a net emission reduction rate of 52%. By scaling up the annual processing capacity of demonstration project to 100 000 tons, the net reduction rate of CO2 emission in the project can be increased to 76%. The research method has broad prospects for carbon reduction applications and can provide technical support for China to achieve carbon neutrality goals.
