Geological storage of CO2 is one of the main components of climate change mitigation strategies. If geostorage is to play a major role in managing emissions, it will be necessary to inject large amount of CO2 into secure geological formations. Prediction of the fate of injected CO2 is necessary to develop and demonstrate the storage technology. Estimating storage capacity, leakage mechanisms and risk assessment need knowledge of various aspects of subsurface CO2 migration.

二氧化碳的地质储存是减缓气候变化战略的主要组成部分之一。如果地质储存要在管理排放方面发挥重要作用，就有必要将大量二氧化碳注入安全的地质构造中。预测注入二氧化碳的命运是开发和示范封存技术的必要条件。估算储存量、泄漏机制和风险评估需要了解地下CO2迁移的各个方面。
