1. Ammonia as an Absorbent of Carbon Dioxide in Post-Combustion Capture - an Experimental, Technical and Economic Process Evaluation
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
2. Kolets återkomst : Koldioxidavskiljning och lagring i vetenskap och politik
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. Green consumption energy use and carbon dioxide emission
Sammanfattning : The aim of this thesis is to explore the quantitative potential to reduce energy requirements and CO2 emissions through changed patterns of consumption, given unchanged levels of consumption expenditure. The thesis question is analysed using a systems analysis approach which in this case means that life cycle assessment data on energy requirements and CO2 emissions related to household consumption are combined with a financial and behavioural analysis to make sure that the budget constraint is kept and that both the first and second order effects of adopting a green consumption pattern are analysed.

4. Towards Sustainable Shipping: Climate change and other environmental perspectives on carbon-based marine electrofuels and onboard carbon capture
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. Ammonia-Based Post-Combustion Capture of Carbon Dioxide
Sammanfattning : Post-combustion capture of carbon dioxide is one of the measures to reduce emissions of carbon dioxide from large point source emitters. In post-combustion capture the carbon dioxide is absorbed from the flue gas by means of a liquid absorbent. LÄS MER
