The SCCS CO2 MultiStore Joint Industry Project provides findings from a study of rocks beneath the UK North Sea, the Captain Sandstone, which has been used by scientists and prospective site operators to predict the performance of a potential CO2 storage formation when the greenhouse gas is injected at two points at the same time over three decades.
The process of storing CO2 captured from power plants and industrial facilities in deep geological formations is called carbon capture and storage (CCS) – a major technological solution for meeting climate change targets. It is anticipated that the study’s conclusions will help build confidence among regulators and investors in the secure containment of CO2 within ‘multiple user’ storage formations.The study’s findings indicate that the secure and permanent storage of carbon dioxide within a single geological storage formation can be optimised by injecting CO2 at more than one point simultaneously.
The work has provided information on how the UK can plan and manage subsurface geological CO2 storage, and design CO2 injection at more than one location by looking at regional-scale performance of an entire geological formation. This is considered a major step in the gradual process of developing the UK’s vast CO2 storage potential.
The findings also suggest that the Captain Sandstone, which lies more than a mile beneath the Moray Firth off northeast Scotland, could securely store at least 360 million t of CO2 in just one sixth of its area when CO2 is injected at a rate of between 6 and 12 million tpy over three decades. As a comparison, 360 million t is the amount of CO2 emitted by Scotland’s energy supply sector over 23 years.
