16. Design, modelling and operation of a 100 kW chemical-looping combustor for solid fuels
Sammanfattning : With the increasing threat of global warming, technologies for efficient capture and storage of the greenhouse gas CO2 are sought after. Chemical-looping combustion is a novel CO2 capture technology that can be applied when burning gaseous, liquid or solid fuels. LÄS MER
17. Conceptual Gas Turbine Modelling for Oxy-fuel Power Cycles
Sammanfattning : The electricity consumption in the world is growing at an ever increasing rate. Today's electricity generation is highly dependent on combustion of fossil fuel. This leads to emissions of carbon dioxide into the atmosphere. Increased atmospheric CO2 concentration results in higher average surface temperature and climate change. LÄS MER
18. Excess heat utilisation in oil refineries - CCS and algae-based biofuels
Sammanfattning : The main objective of this thesis is to investigate two different concepts for CO2 mitigation, from a system perspective, in relation to the oil refining industry: CO2 capture and storage; and algae-based biofuels. For all these processes, process integration with an oil refinery is assumed. LÄS MER
19. Arctic Ocean benthic foraminifera preservation and Mg/Ca ratios : Implications for bottom water palaeothermometry
Sammanfattning : Reconstructions of Arctic Ocean palaeotemperatures are needed to disentangle natural variability from anthropogenic changes and understand the role of ocean heat transport in forcing or providing feedbacks on Arctic climate change. Despite known complications with calcareous microfossil preservation in Arctic Ocean sediments, calcareous benthic foraminifera can be common in interglacial sequences. LÄS MER
20. Life cycle navigation through future energy carriers and propulsion options for the energy transition in shipping
Sammanfattning : The shipping industry's heavy reliance on fossil fuels has a detrimental effect on the global climate, human health, and the natural environment. The shipping sector now relies on the use of cheap and energy-dense heavy fuel oil and is perceived as ‘difficult-to-decarbonize’. LÄS MER
