To strengthen its energy sector and realize the carbon peaking and carbon neutrality goals,China needs to accelerate the construction of a modern energy system,transform its energy development mode,and improve its energy production support capabilities.The integration and complementarity of multiple energy sources is an effective concept and scheme to solve the separation of energy subsystems,optimize the energy pattern,and improve the efficiency of clean energy utilization.Based on the analysis of the existing modes of multi-energy integration,this study summarizes the development status and bottlenecks of multi-energy integration in China and the development trend of multi-energy integration in other countries.Considering existing models,a new multi-energy integration model that integrates energy conversion,complementarity,reuse,and zero-carbon production is proposed to achieve the clean and efficient utilization of energy.To promote the planning,construction,and practice of multi-energy integration in China,we further propose a basic development path and the following suggestions:(1)formulating a medium-and long-term plan to support multi-energy integration based on resource endowment,(2)accelerating the breakthroughs in key core technologies for multi-energy integration to improve the reliability of equipment,(3)strengthening the training of talents related to multi-energy integration,and(4)optimizing the structure of the multi-energy integration industrial chain.
