Development of CCUS Technology in the Context of Carbon Neutrality and Assessment of the Potential for Offshore Storage in Guangdong Province

Abstract

[Introduction] Carbon capture, utilization and storage (CCUS) is one of the key technologies for achieving carbon neutrality. The coastal area of Guangdong Province is a potential area for offshore CO2 storage projects in China. Understanding the development status of CCUS technology in the context of carbon neutrality and analyzing the offshore CO2 storage potential in the coastal area of Guangdong Province are conducive to provide the basis for large-scale CCUS projects, especially the offshore storage projects in the future in China. [Method] The technical routes and development trends of all aspects of CCUS were summarized. The offshore geological storage potential of CO2 in the Pearl River Mouth Basin and the Beibu Gulf Basin off the coast of Guangdong Province was discussed. The problems of offshore CO2 storage in China were summarized, and relevant suggestions were put forward. [Result] In recent years, China has made significant progress in CCUS technology, but some key technologies in transportation and storage has been still at the R&D demonstration stage. The Pearl River Mouth Basin and the Beibu Gulf Basin have enormous geological storage potential of CO2 and an excellent matching relationship with large CO2 emission sources in the coastal area of Guangdong Province, making it an ideal locations for offshore CO2 storage projects. However, offshore CO2 storage still faces problems such as immature technology, high storage costs, uncertain environmental impacts, and inadequate policy and regulation frameworks in China. It is necessary to focus on technological development, promoting cluster projects, and improving policies and relevant regulations to advance the development of offshore CO2 storage. [Conclusion] In the future, China should strengthen research, development and promotion of CCUS, especially the offshore storage technology, to promote the progress of carbon neutrality.
