1. 1. Kolets återkomst : Koldioxidavskiljning och lagring i vetenskap och politik

   Författare :Anders Hansson; Jonas Anshelm; Mats Westermark; Alf Hornborg; Linköpings universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Carbon capture; carbon storage; coal power; CCS; energy politics; climate politics; scenario; ecological modernization; Koldioxidavskiljning; koldioxidlagring; kolkraft; CCS; ekologisk modernisering; energipolitik; klimatpolitik; scenario; Technology and social change; Teknik och social förändring;

   Sammanfattning : I denna avhandling studeras en ny teknik för att hantera växthuseffekten. Den nya tekniken heter koldioxidavskiljning och lagring (CCS) och granskades av FN:s klimatpanel 2005 och tillskrevs då möjligheterna att stå för 15-55% av alla CO2-reducering fram till 2100 och detta till en 30% lägre kostnad än vad som annars vore möjligt.

3. 2. Ammonia as an Absorbent of Carbon Dioxide in Post-Combustion Capture - an Experimental, Technical and Economic Process Evaluation

   Författare :Henrik Jilvero; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cost of capture; carbon dioxide; carbon capture; power plant; ammonia; process simulations;

   Sammanfattning : Carbon capture and storage is vital to facilitating the transition from our current fossil fuel-based energy system to a sustainable energy system. The concept of post-combustion capture is based on the selective chemical absorption of carbon dioxide (CO2). LÄS MER

4. 3. Towards Sustainable Shipping: Climate change and other environmental perspectives on carbon-based marine electrofuels and onboard carbon capture

   Författare :Elin Malmgren; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; liquefied natural gas; power-to-X; methanol; power-to-gas; carbon capture and utilization; thematic analysis; Marine renewable energy; onboard carbon capture; marine fuels; LCA; shipping; electrofuels;

   Sammanfattning : The global, local, and regional environment is under pressure from human activity. Shipping is a human activity causing emissions to air, water, and soil, which has direct and indirect effects on the environment. LÄS MER

5. 4. Precipitating Amine Absorption Systems for Carbon Capture

   Författare :Hanna Karlsson; Avdelningen för kemiteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CO2 capture; Non-aqueous; AMP; Solubility; Heat of absorption;

   Sammanfattning : Carbon capture using amine-based absorption is an established technology for the separation of gaseous CO2. It is used in the upgrading of gaseous fuels, and it has also been suggested that it could play a crucial role in the mitigation of climate change through post-combustion carbon capture and sequestration (CCS), and by creating carbon sinks through bioenergy CCS.

7. 5. Decarbonising plastics – On the technologies and framings of carbon capture and utilisation

   Författare :Ellen Palm; Miljö- och energisystem; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Plastics; Carbon capture and utilisation; Carbon circularity; Industrial decarbonisation; Climate mitigation; Interdisciplinarity;

   Sammanfattning : Plastics consist of fossil fuels, from both a feedstock and energy perspective and thus need to decarbonise. This thesis maps and explores the framings and technologies that surround plastics decarbonisation and the potential mitigation pathway of carbon capture and utilisation. Here, three of the main findings are presented. LÄS MER
