CO2-DISSOLVED: a Novel Concept Coupling Geological Storage of Dissolved CO2 and Geothermal Heat Recovery – Part 1: Assessment of the Integration of an Innovative Low-cost, Water- based CO2 Capture Technology

Abstract : The CO2-DISSOLVED project evaluates the feasibility of coupling capture and storage in saline aquifer of dissolved CO2 , and geothermal heat recovery. The proposed system basically relies on the integration of a patented water-based in-well CO2 capture facility (Pi-CO2) in a classical low-enthalpy geothermal doublet. The results of this preliminary engineering design study demonstrated that (1) the use of composite materials for the wells casings would be compatible with the injection of the corrosive CO2-rich brine; (2) the housing of the Pi-CO2 system in a separate large diameter well associated with a dedicated CO2 injection line integrated in the doublet injection well is the best option for efficient CO2 capture and dissolution in brine.
