1. Biogas in Sweden - Opportunities and challenges from a systems perspective
Sammanfattning : Addressing today’s challenges of reducing our dependence on fossil fuels and related emissions of greenhouse gases requires measures such as increased energy efficiency and replacement of fossil energy carriers with renewable ones. Biogas is one of the fastest growing renewable energy sources in the world and the overarching purpose of the research presented in this doctoral thesis is to explore the prospects of an increased production and utilization of biogas in a Swedish context.

2. Techno-economic assessment of wind energy for renewable hydrogen production in Sweden
Sammanfattning : Wind energy deployment has been growing globally. The resource is expected to play an important role in achieving economic and environmental sustainability - depending on its level of availability, economics, and policy. Sweden has committed to have 20 TWh/year production of onshore wind energy in the national electricity sector by the year 2020. LÄS MER
3. Partial CO2 capture to facilitate cost-efficient deployment of carbon capture and storage in process industries - Deliberations on process design, heat integration, and carbon allocation
Sammanfattning : Climate change requires that all energy-related sectors reduce drastically their greenhouse gas (GHG) emissions, at a global rate of 1–2 GtCO2 per year, starting now. Process industries, such as the iron and steel, cement, petrochemical, and oil-refining industries, are inherently carbon-intensive, and carbon capture and storage (CCS) is one of the few options available to achieve the required deep reductions in carbon dioxide (CO2) emissions.

4. Pathways to deep decarbonisation of carbon-intensive industry in the European Union - Techno-economic assessments of key technologies and measures
Sammanfattning : By Year 2050, the EU has committed itself to reducing greenhouse gas emissions by 80%–95%relative to the levels in 1990, so as to contribute to global efforts to limit the long-term globalaverage temperature increase to.... LÄS MER
5. Low-temperature based thermal micro-grids: operation and performance assessments
Sammanfattning : Energy use in the urban environment is vital for the proper functioning of our society, and in particular, comfort heating –or cooling– is a central element of our energy system often taken for granted. Within this context, district energy systems and especially, district heating (DH) systems must evolve to adapt to the upcoming decades-long transition towards a sustainable energy system. LÄS MER
