The underground disposal of carbon dioxide

Underground disposal of carbon dioxide is an option for reducing carbon dioxide emissions. This project demonstrated the feasibility and practicality of underground disposal, and concluded that it is a technically feasible option, although generally too costly under current market conditions. It identified that most European storage capacity is located under the North Sea, at depths of 800 m or more.

The study estimated the quantity and quality of available carbon dioxide from various types of power station, and assessed methods for gas separation and compression. It then evaluated the potential amount of storage capacity available underground for each of the European Union countries and Norway, both on-shore and offshore. The study then identified requirements to ensure safety and stability, and constructed a simulation model of the recovery and disposal of carbon dioxide and possible opportunities for carbon dioxide injection to be used for enhancing hydrocarbon recovery. Finally, a techno-economic model was developed to establish and evaluate costs associated with collection and disposal of carbon dioxide. The study demonstrated the feasibility and practicality of carbon dioxide disposal underground. To separate the carbon dioxide from the power station flue gas is the most costly part of the whole process. Storage could be in deep porous and permeable reservoir rocks, where the free carbon dioxide would be in a dense, supercritical phase at depths of around 800 m or more. Shallow sub-surface storage is impractical. The study identified that approximately 800 GTm of carbon dioxide storage capacity is available in the European Union and Norway. Most of this is located under the North Sea. If, however, carbon dioxide storage can be combined with enhanced oil recovery, then cost credits from the sale of recovered oil could totally defray the costs of carbon dioxide recovery at power stations.
