Within the EU-funded project MiReCOL (Remediation and Mitigation of CO2 Leakage; project number 608608), a comprehensive review was undertaken of techniques available for the remediation of leakage of CO2 to the near surface environment, here defined as the depth range of typical remediation techniques used by the pollution clean-up industry. The review drew from existing relevant fields of experience such as the remediation of groundwater pollution; the remediation of industrial waste; CO2-EOR, natural gas storage sites; the geothermal energy industry; the construction of dams (as barriers to subsurface fluid flow); pilot scale CCS projects and natural analogues.
