    摘要:

    人类活动造成的CO2排放是全球气候变暖面临的主要挑战之一。CO2封存有望成为全世界减少碳排放份额最大的单项技术。海洋碳捕获、利用和封存(OCCUS)可以在较短时间内提供最大的碳封存能力,与其他地质封存方法相比更加安全有效。而且,多相态形式的CO2(气态、液态、固态和水合物)可以在海洋纵深尺度上实现直接注入。海洋碳封存是一项发展潜力巨大、优势明显的新兴碳封存技术,是实现大规模碳减排的重要措施之一,具有广阔的应用前景。因此,笔者等系统地阐述了海洋CO2直接注入、封存(OCS)的基本原理、技术现状、监测与评估,以及环境方面的影响,并对高效CO2注入技术,CO2泄漏的检测、防范与补救技术,以及海洋碳封存的生态后效等方面进行了展望。

    Abstract:

    The increase in anthropogenic CO2 concentration is one of the main challenges of the mankind. CO2 sequestration is expected to become one of the world's most significant technologies for reducing carbon emissions. Among the sequestration methods, Oceanic Carbon Capture, Usage, and Storage (OCCUS) offers the highest capacity for storage in a shorter period and is safer in terms of CO2 retention compared to geological sequestration methods. CO2 can be injected into oceans at various depths and forms (phases), including liquid, solid, gas, and supercritical. Marine carbon sequestration is an emerging carbon sequestration technology with excellent development potential and known advantages. It is one of the essential measures to achieve large-scale carbon emission reduction and has broad application prospects. Therefore, this paper systematically focuses on the basic principles, technical status, monitoring and evaluation, and environmental impacts of Ocean CO2 Direct Injection and Storage (OCS). Moreover, we elaborate on the efficient ways of implementing CO2 injection, CO2 leakage detection, prevention and remediation technology, and ecological aftereffect of ocean carbon sequestration.
