| Abstract: |
| The world is now facing a critical challenge: global warming. Addressing this issue requires a collective effort to reduce carbon emissions and achieve carbon neutrality, a goal that has gained international consensus. In recent years, carbon capture, utilization, and storage (CCUS) has emerged as a critical tool in the fight against carbon emissions, and it is presently in a rapid phase of development. Among the various methods incorporated within CCUS technology, CO2 ocean storage shows the most potential. Therefore, understanding its current developmental status is crucial for further advancements in CO2 storage research. This paper provides an overview of the methods and mechanisms of CO2 ocean storage and summarizes the progress made in CO2 marine storage technology at home and abroad. It also outlines the enormous potential for CO2 ocean storage and the benefits of source-sink matching in China. However, it also considers the potential environmental implications for CO2 ocean storage, which could be far from negligible. Finally, the paper points out that it is necessary to promote research on ocean storage technologies, explore the extent of ocean storage capacity, and accelerate carbon emission reduction to achieve carbon neutrality as soon as possible. |
