Calcifying organisms in changing shallow and deep marine environments

Egilsdottir, Hronn (University of Iceland, School of Engineering and Natural Sciences, Faculty of Earth Sciences, 2017-02-08)

Anthropogenic CO2 emissions, which are resulting in ocean acidification and a decrease in the saturation state for calcium carbonate (Ω), are a particular threat to calcifying marine biota. The aim of this thesis is to fill important knowledge gaps ...
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 ...
Why do RuO2 electrodes catalyze electrochemical CO2 reduction to methanol rather than methane or perhaps neither of those?

Tayyebi, Ebrahim; Hussain, Javed; Skulason, Egill (Royal Society of Chemistry (RSC), 2020-09-21)

The electrochemical CO2reduction reaction (CO2RR) on RuO2and RuO2-based electrodes has been shown experimentally to produce high yields of methanol, formic acid and/or hydrogen while methane formation is not detected. This CO2RR selectivity on RuO2is ...
