Abstract: In the paper, the present situation of the development of ocean tidal current energy power generation technology and equipment in China is summarized, and compared with the international leading level. Furthermore, our advanced aspects and shortcomings are pointed out. At the same time, the opportunities come from China’s "ocean power" strategy and "carbon peaking and carbon neutrality" strategic objective and the following challenges are analyzed. Moreover, suggestions and opinions on the future development direction of China’s ocean tidal current energy power generation technology and equipment are put forward.
