Abstract: In the context of global carbon neutrality, the world's major economies have successively issued carbon neutrality strategies and actively promoted the research and development of clean energy technologies. Based on the clean energy database of the International Energy Agency, this paper conducts research and analysis from five dimensions: technology field, technology maturity, importance of net zero emissions, major technology countries and technology leaders in different fields, in order to explore the key R&D areas and technology leadership of clean energy technology. nation. The research findings: (1) The ten key R&D areas of clean energy technology in the context of global carbon neutrality are identified. (2) The technology leaders in different fields of construction, energy transition, transportation, CO2 infrastructure and industry are sorted out. (3) Locked in the areas of advantages and disadvantages of my country's clean energy technology. On this basis, combined with the development status of clean energy technology in my country, policy recommendations are put forward from the perspectives of R&D layout, R&D model, and international cooperation. The research results provide reference and enlightenment for my country's clean energy technology research and development layout and science and technology policy formulation.
