粤港澳大湾区岸碳入海发展策略探析

Analysis of the development strategy for carbon dioxide offshore storage in the Guangdong-Hong Kong-Macao Greater Bay Area

岸碳入海是区别于陆地二氧化碳地质封存的一种碳封存途径。岸碳入海国际可借鉴经验较少、中国国内尚无先例。背负中国推进“双碳”目标、实现绿色发展先行地的使命,经济发达且临海的粤港澳大湾区具有率先发展岸碳入海的优越条件,但存在项目周期长、技术尚未成熟的挑战,有较大的商业风险和安全风险。粤港澳大湾区发展岸碳入海建议按照“统一规划、技术先行、示范摸索、集群发展”的策略进行;科学统筹项目执行;政府层面给予项目配套支持政策;相关企业与区域内具备CCUS领先技术的国有企业合作,共同搭建商业模式,并根据发展状况进行商业模式的迭代更新,以期为中国实现碳中和目标探出一条新路。

Carbon dioxide offshore storage is a kind of carbon storage pathway which is different from the geological storage of carbon dioxide on land,and there are fewer international references and no domestic precedents for carbon dioxide offshore storage.With the mission of promoting the“dual carbon goals”and realizing green development in China,the Guangdong-Hong Kong-Macao Greater Bay Area,which is economically developed and adjacent to the sea,has the advantageous conditions to take the lead in developing carbon dioxide offshore storage,but there are such challenges as long project cycle,immature technology,greater commercial and safety risks.The development of carbon dioxide offshore storage in the region is recommended to be carried out according to the strategy of“unified planning,technology first,demonstration&exploration,and cluster development”,with scientific coordination of project implementation,governmental supporting policies,cooperation between enterprises with leading CCUS technologies in the region,and joint construction of business models.It is expected to updated iteratively in accordance with development conditions so as to explore a new approach to achieving carbon neutrality goal in China.
