The ocean is the largest and most active carbon reservoir in the world. Through ocean-atmosphere exchange and the photosynthesis of marine plants, the uptake of carbon dioxide (CO2) by the ocean is much greater than that by soil and vegetation on terrestrial areas. This is essential to mitigate and ameliorate today's global warming which is caused by rising atmospheric CO2 concentration. Therefore, to achieve the goal of "carbon neutrality" around the country, it is an effective approach to sequester CO2 in the ocean. This paper summarizes the technical application scope and methods of ocean carbon sequestration. By analyzing correlative patents in the world, the development trend and the advanced experiences of ocean carbon sequestration are studied. This study also provides some suggestions for the future development of ocean carbon sequestration technologies.
