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.
