【摘要】 碳捕集与封存(CCS)技术已被广泛地认为是一种潜力巨大、可供选择的CO2减排手段。据预测,其减排贡献将从2020年占总减排量的3%上升至2030年的10%,并在2050年将达到20%左右,成为CO2减排份额最大的单项技术。本文介绍了CCS的主要技术环节(捕集、运输、封存)、封存地类型和目前国际上开展的主要CCS示范项目及发展趋势。同时特别探讨了海底封存CO2的可行性、封存潜力以及我国在海底封存CO2方面的研究进展和发展前景。更多还原

【Abstract】 Carbon capture and storage(CCS) has been widely recognized as one of the most potential options to mitigate carbon emission to eventually stabilize carbon dioxide(CO2) concentration in the atmosphere.CCS is an important carbon dioxide emissions abatement technology in the move towards a clean energy future and will contribute to the least-cost route of emissions abatement.According to International Energy Agency(IEA),in the 450ppm scenario,CCS abatement contribution has to grow from 3% of the global abatement portfolio in 2020 to 10% in 2030 and finally reach 19% in 2050,when it will become the largest single technology in the portfolio.Three parts of CCS,which are carbon capture,transport and storage are analyzed in this paper.Especially the feasibility,storage capacity and prospect of marine CCS are discussed.更多还原
