About the Catalogue

The CO2 Storage Resource Catalogue is an independent assessment of the maturity of geologic CO2 storage evaluations worldwide

The 30 countries evaluated in the CO2 Storage Resource Catalogue so far represent three cycles of a six-year public resource provided by OGCI. The countries currently covered are:

Section 4.3 of the 2022 report describes the updates made in Cycle 3 of the CO2 Storage Resource Catalogue and released in March 2022.

The methodology developed by Storegga closely follows the definitions of the Storage Resource Management Scheme (SRMS). The evaluated geologic formations are assigned to different SRMS maturity classes following the methodology summarised in the classification flowchart and report.

The SRMS is a project-based classification scheme. The majority of resource evaluations included in the Catalogue are not project-based and hence non-commercial categories of the SRMS scheme are dominant. This result highlights the critical need for the CCUS industry to describe the project-specific requirements (infrastructure, number of penetrations) to deliver a specific resource.

The goal of the CO2 Storage Resource Catalogue is to become the global repository for all future storage resource assessments. To submit your published resource, please use this form.
