基于文献计量的燃煤电厂碳排放研究进展

Research Progress of Carbon Emissions from Coal-Fired Power Plants-Econometric Analysis Based on Bibliometrics

燃煤电厂是全球二氧化碳排放的主要贡献者,燃煤电厂碳排放研究具有学科交叉性的同时又具有系统性和复杂性,关于全面阐述燃煤电厂碳排放的研究进展与不足鲜有报道.为此,本文应用VOS viewer对国内外相关研究进行分析,阐明了燃煤电厂碳排放的研究现状与方法,并对其进行了综述.研究发现:1)对燃煤电厂碳减排计量研究已有了初步进展,但从技术层面减排的研究仍然不足;2)燃煤电厂碳减排研究内容丰富,研究尺度涵盖国家、地区、城市,主要分析各决策单元的能源效率和二氧化碳减排的可行性;同时分别研究了燃煤电厂不同机组的减排效益;3)研究方法包括燃煤电厂的净零排放技术、碳交易、碳税等政策控制或运营管理;4)燃煤电厂碳减排研究多集中于燃烧阶段的计算,而从全生命周期的角度研究较少.文章建议未来可从全生命周期的角度计算碳排放,提高机组燃烧效率的技术,为实现碳中和作贡献.

Coal-fired power plants are a major contributor to global CO 2 emissions.Research on carbon emissions from coal-fired power plants is interdisciplinary yet systematic and complex,Little has been reported on the progress and shortcomings of research to fully describe carbon emissions from coal-fired power plants.To this end,VOS viewer was applied to analyze relevant domestic and international studies to clarify the current status and methods of research on carbon emissions from coal-fired power plants and to review them.The study found that:1)Initial progress has been made in the research on carbon emission reduction measurement for coal-fired power plants,but there is still a lack of research on emission reduction from the technical level.2)The research on carbon emission reduction in coal-fired power plants is rich in content,and the scales of research include countries,regions,and cities to analyze the feasibility of energy efficiency and carbon dioxide emission reduction in each decision-making unit;at the same time,the emission reduction benefits of different units of coal-fired power plants are studied separately.3)Research methods include net-zero emission technologies for coal-fired power plants,carbon trading,carbon taxes,and other policy controls or operational management.4)Carbon emission reduction from coal-fired power plants is mostly calculated from the combustion stage,and less from the perspective of whole life cycle research.In the future,carbon emissions can be calculated from a whole life cycle perspective,and technologies to improve the combustion efficiency of units can be studied to contribute to achieving carbon neutrality.
