浅议C02地质封存的潜在风险

随着气候的不断变暖，全球开始寻找减缓气候变暖的技术及措施，在所有减排技术中，CCS技术贡献达20％以上。CCS技术虽是有效减排CO2和提高石油、天然气等能源采收率的技术手段，但目前该技术尚处于发展阶段，还存在一些潜在的风险问题，捕集、运输、封存三个环节都存在CO2泄露的风险，泄露将污染地下水、影响动植物甚至人类，还有可能诱发地震等。主要研究了CCS技术的地质封存环节C02泄露存在的潜在风险，分析了地质封存的CO2泄漏的方式及危害，并提出了可采取的应对措施。

A Discussion about Potential Risks of Geological Storage of CO2

With the increasing global warming, the whole world has been looking for me tecnnology ana measures to mitigate the climate change. Of all the emission reduction technologies, the CCS technology makes 20% of the contribution. Though it could effectively reduce the carbon dioxide emission and increase the the oil and natural gas, the CCS technology has yet fully developed. There is the CO2 leakag recovery efficiency of e risk during its cap- ture, transport and storage, which would lead to groundwater pollution. The leakage would also be harmful to the plant, the animal and even the human being. It could induce the earthquake. In this article, we mainly discusses about the CO2 leakage risk of the CCS technology during the geological storage stage, including the ways and harm of the leakage. The countermeasures are proposed.
