A H2020 funded research project

The CarbFix2 project builds on the success of the CarbFix process. The CarbFix2 goal is to move the demonstrated CarbFix technology from the demonstration phase, to a general and economically viable complete CCS chain that can be used through Europe, and throughout the world. 

Towards this goal CarbFix2 will extend the original CarbFix approach from the demonstration stage in one location to implementation under more diverse conditions, with special emphasis on the sea-bed. Because the methods employed to fix CO2 in the bedrock crave both water and basaltic rock, scientists now have focused on the ocean floor. There, extensive field of basalt can be found and, naturally, lots of water. To significantly lower the cost of CCS, major effort in CarbFix2 is focused on optimising the capture and storage of impure CO2, using a novel water-based technique, providing an added value to CCS. By meeting these goals, the CarbFix2 project can increase the safety, and geographical and economical applicability of CCS.

The Partners


Reykjavik Energy, Iceland - the project co-ordinator

Reykjavík Energy (Orkuveita Reykjavíkur, OR) is a public utility company providing electricity, geothermal water for heating, and cold water for consumption and firefighting. OR‘s principal owner is the City of Reykjavík, and it provides its services through three subsidiaries; Veitur Utilities, ON Power, and Reykjavík Fibre Network, The group harnesses hot water from geothermal fields in Reykjavík and operates geothermal plants at Hellisheidi and Nesjavellir where electricity and hot water is generated.

OR has since 2007 been involved in development, testing and demonstration of a full CCS cycle at one of its power plants, through the CarbFix project, which has since then been extended to industrial scale.

CNRS, France

CNRS, France. The Centre national de la recherche scientifique is a government‐funded research organization, under the administrative authority of France's Ministry of Research. It involves 25,000 permanent employees  and 7,000 temporary workers, making it the largest fundamental science agency in Europe. Research in the CarbFix2 project will be performed by the Experimental Geochemistry group of the GET laboratory (CNRS UMR 5563) located in Toulouse. The laboratory is equipped with the state‐of‐the‐art equipment for measuring and interpreting rate experiments and is renowned for its high quality experimental and theoretical studies on mineral‐fluid interactions, and its high scientific productivity. CNRS is one of the founding members of the CarbFix project.


University of Iceland

As one of the founding members of the CarbFix project, the University of Iceland is the largest teaching and research institute in Iceland with about 12,500 students of which 3,500 are graduate students. The Institute of Earth Sciences is an academic research institute hosted within the Science Institute, University of Iceland and comprises of about 30 teaching and research faculty members, 12 Nordic research and postdoctoral fellows, and about 50 graduate students. 

Research within the CarbFix2 project is performed by the Aquatic Geochemistry Group of IES, who is currently monitoring CO2 and H2S capture from geothermal power plants and its storage in basaltic rocks, conducting thermodynamic and kinetic laboratory experimental studies of mineral‐fluid‐gas interactions and researching natural analogues for carbon storage in basaltic rocks. The geochemistry laboratory is equipped with the state‐of‐the‐art equipment for measuring and interpreting laboratory rate experiments as well as analysing the natural fluid chemistry


Climeworks, Switzerland

Climeworks AG (CW) was founded in 2009 as ­a Spin‐off Company from ETH Zurich and is registered as a public limited company (AG) in Zurich, Switzerland. CW provides solutions for efficiently capturing CO2 out of ambient air (“direct air capture”, DAC). Onsite DAC plants from CW offer a competitive and environmentally friendly CO2 supply to its customers. The two main advantages of CW products are the location independency, a DAC plant does not need any point source of COemissions like flue gas streams since atmospheric air is available nearly everywhere, and the energy supply, which can largely be covered by low‐temperature heat that is often available as waste heat.


AMPHOS21, Spain

AMPHOS21 Consulting S.L. (A21) provides scientific and technical consultancy services addressing a range of environmental issues, mainly associated with the management and disposal of hazardous wastes, contaminated groundwater and soils as well as environmental planning and management. The main output is the expert advice to national geological agencies and regulators, along with industrial innovation. AMPHOS 21 counts on a team of more than 40 highly qualified professional specialized in scientific and technical disciplines related to geosciences, climate change and waste and energy geological storage.

AMPHOS21 is leader in innovative solutions of modelling of underground storage processes, both physical and geochemical. AMPHOS21 was also involved in the CarbFix project, seed of the actual CarbFix2 project.

The Work Packages

The CarbFix2 project consists of the following work packages (WP):

WP1 Project Management

- lead by Reykjavík Energy

WP2 Air Capture using waste heat

Focusing on the Direct Air Capture pilot plant at Hellisheidi; the commission of the plant, the operation, and the results of the pilot project - lead by Climeworks

WP3 On shore injection

Focusing on the activities at the Hellisheidi site, including building a reactive transport model of the site, conducting a tracer test, and monitoring the fate of the injected gases.

- lead by University of Iceland and Amphos21

WP4 Off Shore injection

Focusing on the first steps towards injection on CO2 using seawater, including lab work on CO2-basalt-seawater interaction, and doing a site characterisation including performing a tracer test at a possible on shore site where CO2-charged seawater could potentially be injected in the future. - lead by CNRS

WP5 Economic/feasibility analysis of the entire CCS cycle

- lead by Reykjavík Energy

WP6 Dissemination and public engagement

- lead by Reykjavík Energy
