我国CO2捕集与封存的技术路线探讨

地球温暖化问题已引起全球的密切关注，CO2是促成地球温暖化的主要因素。为了缓解地球温室效应，将大气温室气体浓度稳定在一个安全的水平上，必须减少CO2排放。CO2捕集与封存（CCS）是一种新型岩土工程，具有规模大、潜力大、成本较低、技术成熟度较高、与化石能源结构相容性好等特点，被认为可能具有较高减排贡献度，能够降低综合减排成本和减缓能源结构转变带来的经济冲击。国外已投入了很大的研发资金并且制定了研发路线。中国的研究才刚刚起步，尚未制定开发路线。根据大量调查分析，提出了中国中长期CCS研发技术路线。

Discussion on technical roadmap of CO2 capture and storage in China

Global warming has aroused a close attention all over the world. Emission of CO2, as a major greenhouse gas, must be reduced for the purpose of stabilizing the concentration of CO2 at a safe level. CO2 capture and storage (CCS), a new kind of geotechnical engineering, is a potential cost-effective and fossil energy-compatible technology, which is considered to play a significant role in global emission control and be helpful in reducing the total greenhouse gas control cost and mitigating the economic impact caused by the drastic transformation of energy structure. Industrialized countries have drawn up CCS R&;D roadmap. CCS research is just getting started in China and the R&;D roadmap has not been drawn up. A mid-long term R&;D technical roadmap of CCS in China is presented based on authors’ investigations and analyses.
