中文摘要: 海洋是全球最大、最活跃的碳库，人类活动排放到大气中的二氧化碳约30%由海洋吸收，而海洋储碳周期达数千年，这对缓解并改善全球气候变暖至关重要。利用海洋吸收和封存二氧化碳是实现碳中和目标的重要技术手段。文章定义了海洋碳封存的专业技术范围，总结了海洋碳封存相关的技术方法，分析了当前海洋碳封存的技术发展趋势及国内外先进技术经验，以期为我国加快实现碳中和目标提供管窥之见。
Abstract: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.
