    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 ...

    Catchment export of base cations: improved mineral dissolution kinetics influence the role of water transit time 
    Erlandsson Lampa, Martin; Sverdrup, Harald Ulrik; Bishop, Kevin H.; Belyazid, Salim; Ameli, Ali; Köhler, Stephan J. (Copernicus GmbH, 2020-06-03)
    Soil mineral weathering is one of the major sources of base cations (BC), which play a dual role in forest ecosystems: they function as plant nutrients and buffer against the acidification of catchment runoff. On a long-term basis, soil weathering rates ...

    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. ...

    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 ...

    Uterine leiomyomas are common benign tumors of the myometrium. We performed a meta-analysis of two genome-wide association studies of leiomyoma in European women (16,595 cases and 523,330 controls), uncovering 21 variants at 16 loci that associate with ...
