Low-carbon composite energy system concept map
Recently, the joint research teams of the Shanghai Research Institute of the Chinese Academy of Sciences and the Shanghai University of Science and Technology have made progress in the research of low-carbon development strategies for coal chemical industry, and constructed a low-carbon composite energy system in which nuclear energy/renewable energy and coal resources are coupled to deal with coal-rich countries. The large-scale reduction of global carbon dioxide presents an innovative solution.
The distinctive features of the low-carbon composite energy system and its system integration are the effective coupling of low-carbon energy and traditional carbon-containing energy, and the integration of corresponding CO2 emission reduction and conversion and utilization technologies to achieve low-carbon and high-efficiency production capacity from the system perspective. Provide CO2 emission reduction at the same time as supply, provide solutions for low-carbon and high-efficiency utilization of coal.
The research team centered on the idea of system integration of 'low-carbon composite energy system', focused on the characteristics of carbon-rich and hydrogen-depleted coal in the chemical utilization process, and produced fuels and chemicals through a low-carbon energy hydrogen production technology coupled with coal gasification process to achieve a coal chemical process. The carbon-hydrogen balance eliminates the direct carbon emission source of traditional coal chemical industry—water gas shifting process, greatly improves the energy efficiency and carbon efficiency of coal utilization process, and significantly reduces carbon emissions. Economic analysis shows that low-carbon composite energy system will be Under the background of the decline of low-carbon energy prices and the collection of carbon taxes in the future, it is highly competitive. Scenario analysis and research found that the adoption of this system integration will bring significant carbon emission reduction effects.
