Main tasks and deliverables (GB)




We greatfully acknowledge the support and funding of the project from the Region Centre - Val de Loire


Main tasks

The project is composed of four main components: i) Coordination, ii) Inventory of CO2-DISSOLVED-compatible sites in the CVL Region, iii) Case studies and iv) Dissemination.

A description of the main tasks and the partners involved is given in the table below



Partners involved

i) Coordination

1. Coordination

Ensure the smooth running of the project

Lead - BRGM

ii) Inventory of CO2-DISSOLVED-compatible sites in the CVL Region

2. Data collection and formatting: geothermal potential in the CVL Region

Collect and format data on geothermal potential in the CVL Region to feed into the Geographical Information System (GIS) that will serve to map the data and create a synthesis. More specifically, this task will: (1) undertake an inventory of available data (paper and digital), (2) assess deep geothermal potential at the scale of the CVL Region, and (3) produce harmonized digital documents that will feed into the GIS (T4).



3. Extraction and formatting of IREP* data on local industrial CO2 emitters

Extract and format data to be used to identify and characterize industrial sites emitting CO2 in the CVL Region.

* IREP: Registre des Emissions Polluantes (National Pollutant Emission Register)

Lead - BRGM

4. Preparation of presentation materials for local industrial CO2 emitters

Gather information together into a single presentation on a future pilot project to demonstrate the CO2-DISSOLVED concept. The presentation will be targeted towards industrial manufacturers, but will also be made available to the CVL Region for use if they so wish. It will highlight the advantages of the technology and propose an envisaged framework for future deployment. Its purpose is to prospect for industrial partners and demonstrate the advantages of getting involved upstream in a pre-feasibility study that the project team would undertake for two given sites (T12).

Lead – Laurent Jammes




5. Establishing contacts and meetings with the local industrial CO2 emitters identified in T3

Establish contacts with the industrial CO2 emitters catalogued during the survey (T3) and with sites having a geothermal potential >‘low’ (as defined in T2). Organize site visits and collect additional data needed for T6.

Lead – CCI



6. Summarizing data collected from the industrial contacts and integration into the database

Complement the ‘industrial’ database, already containing public IREP* data (T3), with data collected from the industrial contacts visited (T5). The aim is i) to better characterize the signal of CO2 emissions in the atmosphere (constant/continuous flow, presence of emission peaks, periods of no emissions, etc.) and ii) assess the possibilities of utilization of the geothermal energy recovered directly by the industrial processing and/or to supply a heating/cooling network.

7. Create a GEOCO2 GIS (Geographical Information System)

Create the final deliverable of the first part of the project dedicated to assessing the potential of applying the CO2-DISSOLVED concept in the CVL Region, namely an interactive GIS (Geographical Information System) that allows viewing all data acquired and formatted (T2, T3, T6) displayed on a regional cartographic background.

Lead - BRGM

iii) Case studies

8. Selection of two case studies

Based on the results from T2, T3 and T6, and from the industrial contacts visited (T5), select the two most potentially interesting sites where the CO2-DISSOLVED concept can be applied, and carry out a pre-feasibility study (T9-12).

Lead – BRGM



9. Summary of local geological, hydrogeological and geochemical data

Undertake an interpretation and summary of the geological, hydrogeological and geochemical data, at local scale, available for the two selected sites.

Lead - BRGM

10. Digital simulations and pre-sizing of installations

Undertake digital simulations of the possible scenarios for applying the CO2-DISSOLVED technology to the two industrial CO2-emitting case studies selected in T8. Calculations will be made to assess the capacities of the geothermal reservoir that will serve the double purpose of supplying geothermal energy and storing CO2 in dissolved form. After the simulations are done, a pre-sizing/scaling study will be made of the installations/fittings.

Lead – BRGM


11. Economic study

Assess the economic profitability of the two case studies according to various hypotheses (scenarios), and analyse the sensitivity of the results in view of the main sources of incertitude. This study will check the economic interest of combining two subsurface technologies, geothermal and storage of dissolved CO2, notably by the pooling of certain CAPEX (Capital Expenditure).

Lead – Laurent Jammes

12. Outcomes of the two case studies

Conduct a summary of the results of the two selected case studies and present the findings in the form of reports and presentations to the industrial partners involved.

Lead – BRGM

iv) Dissemination

13. Science culture activities

Undertake communication and dissemination activities around the project GEOCO2.
