    CarbFix2: CO2 and H2S mineralization during 3.5 years of continuous injection into basaltic rocks at more than 250 °C 
    Clark, Deirdre; Oelkers, Eric H.; Gunnarsson, Ingvi; Sigfússon, Bergur; Snæbjörnsdóttir, Sandra Ósk; Aradóttir, Edda S.; Gíslason, Sigurður Reynir (Elsevier BV, 2020-06)
    The CarbFix method was upscaled at the Hellisheiði geothermal power plant to inject and mineralize the plant’s CO2 and H2S emissions in June 2014. This approach first captures the gases by their dissolution in water, and the resulting gas-charged water ...

    The chemical composition of rivers and snow affected by the 2014/2015 Bárðarbunga eruption, Iceland 
    Galeczka, Iwona; Sigurdsson, Gunnar; Eiriksdottir, Eydis Salome; Oelkers, Eric H.; Gíslason, Sigurður Reynir (Elsevier BV, 2016-04)
    The 2014/15 Bárðarbunga volcanic eruption was the largest in Iceland for more than 200 years. This eruption released into the atmosphere on average 60,000 tonnes/day of SO2, 30,000 tonnes/day of CO2, and 500 tonnes/day of HCl affecting the chemical ...

    The chemistry and potential reactivity of the CO2-H2S charged injected waters at the basaltic CarbFix2 site, Iceland 
    Clark, Deirdre; Gunnarsson, Ingvi; Aradóttir, Edda S.; Arnarson, Magnús Þ.; Þorgeirsson, Þorsteinn A.; Sigurðardóttir, Sigrún S.; Sigfússon, Bergur; Snæbjörnsdóttir, Sandra Ósk; Oelkers, Eric H.; Gíslason, Sigurður Reynir (Elsevier BV, 2018-07)
    The CarbFix2 project aims to capture and store the CO2 and H2S emissions from the Hellisheiði geothermal power plant in Iceland by underground mineral storage. The gas mixture is captured directly by its dissolution into water at elevated pressure. ...

    The effect of the 2014-15 Bárðarbunga volcanic eruption on chemical denudation rates and the CO2 budget 
    Galeczka, Iwona; Oelkers, Eric H.; Gíslason, Sigurður Reynir (Elsevier BV, 2018-07)
    Chemical denudation rates during the 2014–15 Bárðarbunga eruption, calculated using river chemical fluxes, increased substantially confirming that volcanic activity and its products such as fresh lava, and acidic volatiles accelerates these rates. ...

    Environmental pressure from the 2014–15 eruption of Bárðarbunga volcano, Iceland 
    Gíslason, Sigurður Reynir; Stefansdottir, Gerdur; Pfeffer, Melissa; Barsotti, Sara; Jóhannsson, Th.; Galeczka, Iwona Monika; Bali, Eniko; Sigmarsson, Olgeir; Stefansson, Andri; Keller, Nicole Simone; Sigurðsson, Á.; Bergsson, Bergur H.; Galle, B.; Jacobo, V.C; Arellano, S.; Aiuppa, A.; Jónasdóttir, Elín Björk; Eiríksdóttir, E.S.; Jakobsson, Sigurður; Guðfinnsson, Guðmundur; Halldórsson, Sæmundur Ari; Gunnarsson, H.; Haddadi, B.; Jonsdottir, Ingibjorg; Thordarson, Thorvaldur; Riishuus, Morten; Högnadóttir, Thórdís; Dürig, Tobias; Pedersen, Gro; Höskuldsson, Ármann; Gudmundsson, Magnus Tumi (European Association of Geochemistry, 2015)
    The effusive six months long 2014-2015 Bárðarbunga eruption (31 August-27 February) was the largest in Iceland for more than 200 years, producing 1.6 ± 0.3 km3 of lava. The total SO2 emission was 11 ± 5 Mt, more than the amount emitted from Europe ...

    Experimental observations of CO2-water-basaltic glass interaction in a large column reactor experiment at 50 °C 
    Clark, Deirdre; Galeczka, Iwona M.; Dideriksen, Knud; Voigt, Martin J.; Wolff-Boenisch, Domenik; Gíslason, Sigurður Reynir (Elsevier BV, 2019-10)
    Mineralization of water dissolved carbon dioxide injected into basaltic rocks occurs within two years in field-scale settings. Here we present the results from a CO2-water-basaltic glass laboratory experiment conducted at 50 °C and 80 bar pressure in ...

    Basalts are recognized as one of the major habitats on Earth, harboring diverse and active microbial populations. Inconsistently, this living component is rarely considered in engineering operations carried out in these environments. This includes ...

    Pollution from the 2014–15 Bárðarbunga eruption monitored by snow cores from the Vatnajökull glacier, Iceland 
    Galeczka, Iwona; Eiriksdottir, Eydis Salome; Pálsson, Finnur; Oelkers, Eric; Lutz, Stefanie; Benning, Liane G.; Stefánsson, Andri; Kjartansdóttir, Ríkey; Gunnarsson-Robin, Jóhann; Ono, Shuhei; Ólafsdóttir, Rósa; Jónasdóttir, Elín Björk; Gíslason, Sigurður Reynir (Elsevier BV, 2017-11)
    The chemical composition of Icelandic rain and snow is dominated by marine aerosols, however human and volcanic activity can also affect these compositions. The six month long 2014–15 Bárðarbunga volcanic eruption was the largest in Iceland for more ...

    Rapid CO2 mineralisation into calcite at the CarbFix storage site quantified using calcium isotopes 
    Pogge von Strandmann, Philip A. E.; Burton, Kevin W.; Snæbjörnsdóttir, Sandra Ósk; Sigfússon, Bergur; Aradóttir, Edda S.; Gunnarsson, Ingvi; Alfreðsson, Helgi A.; Mesfin, Kiflom G.; Oelkers, Eric H.; Gíslason, Sigurður Reynir (Springer Science and Business Media LLC, 2019-04-30)
    The engineered removal of atmospheric CO 2 is now considered a key component of mitigating climate warming below 1.5 °C. Mineral carbonation is a potential negative emissions technique that, in the case of Iceland’s CarbFix experiment, precipitates ...
