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 ...
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 ...
