1. Decarbonising plastics – On the technologies and framings of carbon capture and utilisation
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
2. 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
3. On the Role of Envisioned Futures in Sustainability Transitions
Sammanfattning : Different kinds of representations of the future are often asked for in order to motivate and inspire societal change. These envisioned futures can be based on political or behavioural change, or may visualize technical developmentwhich could help us solve complex societal problems. LÄS MER
4. Future District Heating Interactions – Modelling Impacts of Industrial Excess Heat Utilisation and Energy Efficient Buildings
Sammanfattning : International goals for climate change mitigation plus energy security targets could be met cost-effectively by interactions between different parts of energy systems. The fourth generation of the district heating systems concept was developed as an attempt to accelerate district heating (DH) systems’ interactions with other energy systems. LÄS MER
5. Cost-efficient integration of variable renewable electricity - Variation management and strategic localisation of new demand
Sammanfattning : The aim of this work was to improve our understanding of how wind power and solar photovoltaics (PV) can be integrated into the European electricity system in a cost-efficient manner. For this, a techno-economic, cost-minimising model of the electricity system is refined for a number of case studies. LÄS MER
