Achieving the carbon emission peaking and carbon neutrality goals is a requirement for promoting the green-oriented transition and innovation development of energy. This article focuses on the related energy strategy of clean and efficient coal conversion technologies. It analyzes the overall development trends of patent from the aspects of patents distribution, sources of technology and patent applicants. The regional distribution of patented technologies shows that China plays a significant role in the clean and efficient conversion of coal, not only the major research center but also the target market. Furthermore, the current important research fields in China are revealed by analyzing the composition of patented technologies in the field of coal conversion. Then, this article analyzes the clean and efficient coal conversion technologies in patent related to the National Science and Technology Progress Award in recent years. On these bases, we put forward the suggestion of transforming key patented technologies to productivity, and seizing the opportunities of the Belt and Road Initiative to enhance the international competitiveness of the modern coal chemical industry of China.
