  1. 1. Geologisk karaktärisering av den kambriska Faluddensandstenen i Östersjön och dess lämplighet för koldioxidlagring

    Kandidat-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Kaisa Bengtsson; [2023]
    Nyckelord :Koldioxidlagring; djupt liggande akvifer; Faludden; St. Sutarve-2018; CO2-storage; deep saline aquifers; Earth and Environmental Sciences;

    Sammanfattning : The Geological Survey of Sweden (SGU) has spent several years investigating the Swedish bedrock to find suitable bedrock for geological storage of carbon dioxide. Deep saline aquifers are considered to have the greatest potential, and the Cambrian Faludden Sandstone subcropping in the Baltic Sea east of Gotland, shows great potential as a storage aquifer.

  3. 2. Negative CO2 Emissions from Chemical Looping Combustion: Gas Cleaning for CO2 Storage

    Master-uppsats, KTH/Kemiteknik

    Författare :Laura Raud Pettersson; [2022]
    Nyckelord :Chemical Looping Combustion; Flue Gas Treatment; Negative emissions; Biomass; CCS; Linde Hampson; Cryogenic Separation; Kemcyklisk Förbränning; Rökgasrening; Negativa Utsläpp; CCS; Biomassa; Linde Hampson; Kryogen Destillation;

    Sammanfattning : Kemcyklisk förbränning (CLC) involverar en icke komplex separation av den bildade koldioxiden (CO2) efter förbränningen eftersom syret (O2) överförs till bränslet via en syrebärare som cirkulerar mellan luft- och bränslereaktorn. Eftersom O2 separeras effektivt från kvävgasen (N2) i luftreaktorn, erhålls en produkt gas som till majoriteten består av CO2 och vatten (H2O). LÄS MER

  4. 3. A 3D Sub-Surface Characterisation of the Arnager Greensand, South-west Skåne

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Gregory Marcel Davies Jones; [2019]
    Nyckelord :Arnager Greensand; digitization; depth conversion; reservoir; storage potential;

    Sammanfattning :  A surface characterisation of the Arnager Greensand in south Sweden, a deep saline aquifer found to be suitable for geological storage of CO2 or energy storage, was undertaken in this thesis. Vintage seismic reflection data only available as scanned tiff images of the final stacked sections were digitized and processed using modern interpretation software to provide new insights into the morphology of the Arnager Greensand and to analyse the reservoir’s potential as an energy storage unit.

  5. 4. The significance of heterogeneity for spreading of geologically stored carbon dioxide

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Christofer Olofsson; [2011]
    Nyckelord :Storage efficiency; Heterogeneity; Variogram; iTOUGH2; ECO2N; Geological storage; CO2; Saline aquifer; Lagringseffektivitet; Heterogenitet; Variogram; iTOUGH2; ECO2N; Geologisk lagring; CO2; Saltvattenakvifär;

    Sammanfattning : The demand for large scale storage of carbon dioxide (CO2) grows stronger as incentives to reduce greenhouse gas emissions are introduced. Geological storage sites such as depleted oil and gas reservoirs, unminable coal seams and deep saline water-saturated aquifers are a few of many possible geological storage sites. LÄS MER

  7. 5. Impacts on plant communities by elevated CO2 concentration

    L3-uppsats, SLU/Dept. of Environmental Assessment

    Författare :Miia Liisa Persson; [2005]
    Nyckelord :carbon dioxide concentration; plant communities;

    Sammanfattning : Our climate is in change. Carbon dioxide (CO2) levels this high, as the present CO2 concentration (≈370 ppm), have not been seen for the past 420 000 years. LÄS MER
