Main tasks, deliverables, and milestones

The CO2-DISSOLVED project proposes to assess the feasibility of a novel CO2 capture strategy in deep saline aquifers, combining injection of dissolved CO2 and recovery of the geothermal heat from the extracted brine.  This alternative to standard supercritical CO2 injection has several benefits including risk reduction and mineralization potential.  However, there are also limitations and an evaluative comparison of this dissolved injection versus standard capture and supercritical phase injection is warranted.  This proposal focuses on the capture and separation of CO2 from low tonnage emission sources (ca. 10-150kt/yr) with local storage for sequestration. The main technical points covered by the scientific and technical program focus on:

  • An innovative CO2 capture and dissolution technology (Task 1),
  • The efficiency of the coupled injection/geothermal heat extraction system (Task 2),
  • Monitoring and risk assessment (Task 3).

The results produced in these three main tasks will be used as input data for the final integration (Task 4) where application to selected test-cases (one in France, one in Germany) will allow us to conclude on the technical-economic feasibility of the whole storage concept.

The following table (click to enlarge) summarizes the deliverables to be produced in the project and their updated status (done/available, in progress, not started). Please notice that according to the patnership agreement and to a request from the ANR, all the reports will remain confidential until the end of the project. By the end of January 2016, all these documents will become accessible to the public through this website or on request to the authors.
