摘要
为解决能源需求与温室气体减排之间的矛盾,采取CO2地质储存方案。地质储存CO2的方法有:非开采煤层储存;含盐贮水层储存;海底储存;地面储存。建立环境效益评价模型,对CO2注入非开采煤层提高煤层气采收率的储存方法进行环境效益评价。结果证明,模型可行,非开采煤层储存CO2的环境效益显著。
To resolve the problem on contradiction between the energy demand and greenhouse gas mitigation, the authors adopted scheme of carbon dioxide underground. There are several methods for CO2 sequestration by geological media： displacement of methane in coal beds, injection in deep salt aquifers and the sea floor storage and ground storage. An assessment model on environmental benefits of the CO2-ECBM technique was set up in this paper. The result proves that this model is feasible, and the environmental benefits are remarkable.
