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： Energy storage is one of the important supporting technologies to achieve the “dual carbon” goals, and it is an important means to stabilize renewable energy fluctuations and reduce the impact of large-scale new energy access on the power grid. At present, the competition of global energy resources is becoming increasingly fierce, and China is also facing significant changes in the adjustment of energy structure. To implement the energy strategy of “four revolutions and one cooperation” in the new era, and to realize the “14th Five-Year Plan” as well as the “Long-range Objectives Through the Year 2035”, China needs to build a new system of energy structure with Chinese characteristics, driven by “clean, low-carbon, safe and efficient” energy resources. Achieving the complementary integration of clean energy and fossil energy is the key to building a new “clean, low-carbon, safe and efficient” energy system. The development of large-scale energy storage technology is not only a necessary measure for the low-carbon and clean power system, but also a powerful means to seize the strategic commanding heights of the international energy technology and ensure national energy security.

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.
