Europe (CO2CARE)

CO2CARE Research and Development:

  • Well-plugging techniques
  • Factors critical to long-term site safety
  • Monitoring methods for leakage detection
  • Remediation technologies
  • Predictive modeling approaches to help define acceptance criteria
  • Risk management procedures and tools to assess
    post-closure system performance

The CO2CARE project, funded by the European Commission under the Seventh Framework Programme, is a collaboration of more than 20 international partners. The project supports the large-scale demonstration of carbon capture, utilization and storage (CCUS) technology by addressing the research related to carbon dioxide (CO2) storage site abandonment. The project focuses on the abandonment and long-term integrity of wells, reservoir management and prediction from closure to the long-term, and risk management methodologies for long-term safety. It relies on integrated laboratory research, field experiments, and state-of-the-art numerical modeling—all supported by literature review and data derived from real storage sites that represent wide-ranging geological and geographical settings. Delivery of technologies and procedures for abandonment and post-closure safety will help establish the technical criteria necessary to assess whether a site meets the high-level requirements for transfer of responsibility defined by the European Union Directive.

Under the CO2CARE project, developed technologies will be implemented at the Ketzin site 40 miles west of Berlin, and dry-run applications for site abandonment will be developed for hypothetical closure scenarios at Sleipner and K12-B site, in the respective Norwegian and Dutch sectors of the North Sea. Partners from the United States (including Battelle and PNNL), Canada, Japan, and Australia will participate. Data obtained from current and closed sites will add to the field monitoring database and place the results of CO2CARE in a world-wide perspective. Research findings will be presented as best practice guidelines. The dissemination strategy will deliver results to a wide range of international stakeholders and the general public.
