Over 99% of injected CO2 will retain after 100 years

This comes from the report 'Deep geological storage of CO₂ offshore UK: containment certainty' from the Department for Business, Energy and Industrial Strategy (BEIS). We urge you to take a look at the full publication, along with its supporting document.

Estimates of containment probabilities for two example sites modelled over 25 years of injection operations and 100 years of post-injection monitoring indicate that more than 99.9% of the injected CO2 will be retained within the storage complex. The two modelled sites are designed to reflect the features of ‘typical’ UK offshore sites, for depleted fields and saline aquifer stores within permitted storage complexes. While the risks will vary on a site-specific basis, the results indicate a very high level of confidence in the long-term security of CO2 containment in typical CCS storage complexes on the UKCS.
