Abstract
The CO2-DISSOLVED project (2013-1016) aimed at evaluating the techno-economic feasibility of capture and storage in a saline aquifer of dissolved CO2, coupled with geothermal heat recovery through a standard doublet system. This project mainly investigated: (1) the hydro-geochemical behavior of the injected CO2 plume in the aquifer, relying on reactive transport modeling, lab experiment and on-site measurements; (2) the integration of a breakthrough CO2 capture technology with major environmental and economic benefits; (3) the assessment of the economic viability on a bioethanol refinery test-case. All the results obtained confirmed the viability of the concept, which was proved to be potentially applicable to several areas in France, Germany, and the USA. The recently launched second phase of the project now aims at preparing the ground for a future industrial pilot.
