Abstract： Promoting the regional demonstration of energy technology for carbon peak and carbon neutrality (referred to as “dual carbon”) is an important part of the Chinese Academy of Sciences’ action plan to support the “dual carbon” goals. This study discusses the significance of carrying out the comprehensive demonstration of “dual carbon” technology from the two dimensions of “technology integration demonstration” and “typical regional demonstration”. Besides, based on the existing research layout in the energy field of the Chinese Academy of Sciences, the idea and four mainlines are proposed for the Chinese Academy of Sciences to promote “multi-energy integration”, which are clean and efficient utilization and coupling substitution of fossil energy, multi-energy complementation and large-scale application of non-fossil energy, industrial low-carbon and zero-carbon process reengineering, and digital intelligent integration optimization, namely. Finally, combined with the work of the Dalian Institute of Chemical Physics, this study discusses the background, goals, and technical routes of the comprehensive demonstration of multi-energy fusion technology in Northern Shaanxi, Liaoning Province, and Shandong Province, respectively for researchers and decision makers.

Abstract： This study first analyzes the driving factors of China’s realization of the “dual carbon” goals from the two aspects of necessity and urgency, and proposes that to achieve the “dual carbon” goals, China shall reshape the energy structure and related industrial systems in a scientific and orderly manner, in which technology innovation plays a crucial leading role. Then, based on the long-term research and deveopment in the energy field of the Chinese Academy of Sciences, the scientific and technological development path to lead the realization of the “dual carbon” goals with the concept of “multi-energy system integration” is proposed, and the connotation of the “multi-energy system integration” concept is elaborated into four technology development paths, including clean and efficient utilization and coupling substitution of fossil energy, multi-energy complementation and large-scale application of non-fossil energy, industrial low-carbon, and zero-carbon process reengineering,and digital, intelligent and multi-energy integration. Finally, suggestions are put forward to promote the implementation of the “multi-energy integration” technology development path.

Abstract： Scientific and technological innovation plays key supporting and leading roles to achieve “carbon peaking and carbon neutrality” goals (referred to as “dual carbon”). It is necessary to make sustained efforts in the three aspects, namely energy structure adjustment, energy consumption, and carbon sequestration, and build a novel multi-energy-integrated energy production and utilization system based on hydrogen energy, energy storage, and methanol, in which the main lines are clean and efficient utilization of fossil energy, large-scale utilization and complementation of clean energy, low-carbon reconstruction of industrial processes, and intelligent multi-energy integration of building and transportation. In 2022, the Chinese Academy of Sciences has launched the scientific and technological action plan to support dual carbon goals. By implementing eight major actions including strategic research, cross-innovation of basic frontiers, breakthroughs in key technologies, comprehensive demonstration of new technologies and other scientific and technological innovation, deploying talent team building, international cooperation, improvement of innovation system capabilities, and popular science and dissemination actions, the action plan is to provide vigorous scientific and technological support for China’s carbon peaking and carbon neutrality goals.

Abstract： Petrochemical industry has been evolved in China for decades as the domestic economics and markets develop. Lack of oil reserves, together with the rapid increase of the demand of liquid fuel and chemicals, leads to the risky and uncontrollable supply of the oil feedstock and meantime hinders the optimization of the structure of China’s chemical products. Coal to chemicals, after more than 30 years’ research and development, is becoming an effective and significant approach to produce basic chemicals such as olefins and aromatics. In view of the relatively abundant coal reserves in China, it is essential to develop coal chemical industries, which can be considered as a complement to petrochemical industries at either the strategical level to produce olefins, aromatics, and ethanol, or at the technical level to directly co-feed methanol with naphtha or toluene for on-purpose production. This opens a potential way for the coordinated development of coal chemical and petrochemical industries in China.

Abstract： Energy is the material basis for the survival and development of a country. Sustainable high-quality development of the economic society with the green transformation of energy resources is a long-term and tough task. The construction of clean, lowcarbon, safe and highly efficient energy system is an important strategic goal putting forward by the government for the future energy development of China, while technological innovation is the key to such goal. Based on the analysis of Chinese energy development status, major problems and great challenges, combining with global energy development trends, this study proposed a new idea on the development strategy of energy technology of China, the main line of which is the clean and efficient use of fossil resources and coupling substitution, multi-energy complementarity and scale application of clean energy, and the low-carbon multi-energy strategic integration.
