University of Iceland

Partner Description

The HASKOLI ISLANDS (University of Iceland, (UI)) is the largest teaching and research institute in Iceland with about 12,500 students thereof 3,500 graduate students. The Institute of Earth Sciences (IES) is an academic research institute hosted within the Science Institute, University of Iceland and comprises 28 faculty members, 6 technicians, 16 research scientists and about 60 PhD and master’s students. The Aquatic Geochemistry Group of IES leads the University of Iceland part in the S4CE project. This group is currently working on CO2 and H2S capture from geothermal power plants and its storage in basaltic rocks, thermodynamic and kinetic laboratory experimental studies of mineral‐fluid‐gas interactions and natural analogue studies for carbon storage in basaltic rocks.

Role in the Project

The Aquatic Geochemistry laboratory is equipped with the state-of-the-art equipment for measuring and interpreting laboratory rate experiments, and natural fluid chemistry. This includes specialised equipment for field sampling at high and ambient temperature and pressure, high and low temperature and pressure mixed-flow laboratory reactors, high pressure 2.5 m long titanium plug flow reactor, multi-collector ICP/MS, simultaneous ICP-OES, ion- and gas-chromatographs, microprobe, SEM and a Fourier Transform Infrared spectrometer.

Main tasks of UI in the S4CE project are in: WP‐7 Natural analogues, WP-4 Laboratory experiments of CO2-gas host rock reactivity using di-water and seawater, WP-5 Carbon injection and chemical monitoring at the CarbFix2 site before and after injection in collaboration with Reykjavík Energy (OR) and SU. Finally, UI will participate in work packages WP 9, Economic Impact Study and WP-10, Transfer of knowledge.


Research professor Sigurdur Reynir Gislason is a geochemist with over 30 years’ experience studying and managing field and laboratory water‐rock‐gas-interaction projects. He is the vice president of the European Association of Geochemistry and the Chair of the Scientific Steering Committee of CarbFix, an international initiative to store carbon in basaltic rocks.

Professor Andri Stefánsson is a geochemist and the vice president of the geology department (UI) with over 15 years’ experience in studying physio-chemical and molecular properties of fluids including thermodynamics of aqueous species and gases in hydrothermal fluids.

Assistant Professor Gabrielle Stockmann is a geochemist with over 10 years’ experience in the field of geochemistry and kinetics of water – rock – gas interactions.

PhD student Deirdre Clark is working on characterisation of the water and gas at the CarbFix2 site before and after CO2-H2S-gas mixture injection.

Laboratory manager Rikey Kjartansdottir a geochemist and expert in laboratory measurements and field sampling of natural waters and gases in all its forms.

Martin Voigt recently completed his PhD related to aqueous geochemistry, including the use of REEs in calcite as paleo-proxies and the behavior of isotopes during basalt-seawater interactions at mid-ocean ridgesin in Toulouse. His current work focuses mainly on low-temperature basalt-seawater interactions, looking at both natural ocean-floor processes and the fate of added CO2 to such systems (as part of the CarbFix2 project).
