1. 1. CCU in Scandinavia: an uncertainty analysis regarding the future state of captured carbon in the region.

   Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

   Författare :Marta Gebellí Carrasco; William Melander; [2023]
   Nyckelord :CCU; E-kerosene; Precast concrete; CO2 utilization; Scandinavian region; Defossilization; Technology and Engineering;

   Sammanfattning : The urgent need to mitigate climate change has prompted researchers to investigate novel strategies to reduce greenhouse gas emissions. One promising technology that might ease the way for sustainable and circular economies is carbon capture and utilization (CCU), which not only captures CO2 emissions but also uses them to produce valuable products.

3. 2. Research on the Hydrothermal Conversion of Xylose Catalysed by CO2-H2O into Furfural

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Robert Liao; [2023]
   Nyckelord :;

   Sammanfattning : Agricultural waste treatment and carbon dioxide emissions from fossil fuel combustion have been critical challenges for sustainable development. This work is part of a study on converting straw into biofuels, which involves using xylose as the material, carbon dioxide (CO2) as the catalyst, and water (H2O) and Gamma-Valerolactone (GVL) as the solvent to produce furfural through hydrothermal conversion.

   Sammanfattning : The Paris Agreement aims to limit global warming to 1.5 degrees Celsius, and Sweden has set a goal toreach net-zero emissions by 2045. Carbon Capture and Storage (CCS) is one method that can reducecarbon dioxide emissions. LÄS MER

5. 4. Techno economic assessment of CCUS for a biogas facility in Sweden : Evaluating the economic feasibility for three CCUS concepts

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Tobias Johansson; Markus Knutsson; [2022]
   Nyckelord :CCS; CCU; CCUS; Biogas; Biologic methanation; Negative emissions; TEA; Techno economic assessment.;

   Sammanfattning : Many countries strengthen their commitments to reduce greenhouse gas emissions to limit climate change and meet the Paris Agreement (Masson-Delmotte et al., 2019). Commitments include achieving net-zero emissions or in some cases even negative emissions (Government offices of Sweden, 2020a; United Nations, 2021a). LÄS MER

7. 5. BECCS - Vägen till negativa koldioxidutsläpp

   Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Tova Langels; Sigrid Sylten Wikell; [2022]
   Nyckelord :;

   Sammanfattning : Enligt FN:s klimatpanel IPCC bör den globala uppvärmningen inte överstiga 1,5 ℃ jämfört med förindustriella nivåer, för att förhindra klimatrelaterade risker. De belyser även vikten av att implementera åtgärder för att uppnå negativa koldioxidutsläpp. LÄS MER
