    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 ...

    Corrosion Behaviour of Materials in Simulated High-Temperature Geothermal Environments 
    Þórhallsson, Andri Ísak (University of Iceland, School of Engineering and Natural Sciences, Faculty of Industrial Eng., Mechanical Eng. and Computer Science, 2022-05-11)
    High enthalpy geothermal fluid utilization has a potential for growth for green and sustainable energy production. Geothermal energy production is often limited by the corrosive nature of the geofluids utilized. For successful, safe and economic ...

    Fluid-rock interaction and H2S and CO2 mineralization in geothermal systems: experiments and geochemical modeling 
    Přikryl, Jan (University of Iceland, School of Engineering and Natural Sciences, Faculty of Earth Sciences, 2018-05)
    Fluid-rock interaction is an important process in nature, and in many industrial fields. Fluid-rock interaction can be utilized to sequester industrial gases like CO2 and H2S in porous rocks of geothermal systems. The gases are re-injected, together ...

    Mineral storage of carbon in basaltic rocks 
    Snæbjörnsdóttir, Sandra Ósk (University of Iceland, School of Engineering and Natural Sciences, Faculty of Earth Sciences, 2017-04-19)
    In-situ carbonation of basaltic rocks could provide a carbon storage solution for the long term. Permanence is essential for the success and public acceptance of carbon storage. The aim of this study was twofold, to evaluate and make a first estimate ...

    Mineral storage of carbon in basaltic rocks at elevated temperatures. A field and experimental study. 
    Clark, Deirdre (University of Iceland, School of Engineering and Natural Sciences, Faculty of Earth Sciences, 2019-10-23)
    The reduction of carbon dioxide (CO2) emissions in the atmosphere is currently one of the main challenges facing humanity. One solution is carbon capture from concentrated sources and directly from the atmosphere, and long term storage in rocks. Basaltic ...

    Modelling CO2 hydrogenation reaction on Pt functionalized UiO-67 Metal-Organic Frameworks 
    Pulumati, Sri Harsha (University of Iceland, School of Engineering and Natural Sciences, Faculty of Industrial Eng., Mechanical Eng. and Computer Science, 2024-02)
    Converting CO2 into value-added products via hydrogenation is of interest due to its potential to reduce and reuse excess atmospheric CO2 and deal with global warming. Metal-organic frameworks (MOFs) are of great interest in this conversion process due ...
