16. Numerical and experimental modelling for wave energy arrays optimization
Sammanfattning : Many wave power conversion devices, especially point-absorbers, do not provide alone the necessary amount of converted electricity to be cost effective, instead they are designed to be deployed in arrays of many units. Such arrays, or parks, can satisfy a large-scale energy demand, reduce the costs of the produced electricity and improve the reliability of the system. LÄS MER
17. Opportunities to broaden biomass feedstocks in thermochemical conversion technologies
Sammanfattning : Global environmental concerns are motivating a growing interest in broadening the biomass feedstock base in several energy sectors, including (i) the domestic heating sector, presently dominated by stem wood combustion, and (ii) biofuel production, presently dominated by edible crops. The objective of this thesis is to investigate new opportunities to broaden the biomass feedstock in thermochemical conversion technologies. LÄS MER
18. Biofuels from Kraft Black Liquor : Pilot-Scale Gasification Development and Techno-Economic Evaluation of Industrially Relevant Biofuel Production Pathways
Sammanfattning : Fuel combustion for transport was responsible for 24% of EU-28 greenhouse gas (GHG) emissions in 2016. Member states are expected to ensure that the share of renewable energy in the transport sector is at least 14% by 2030. Some countries, such as Sweden, have more ambitious targets. LÄS MER
19. Renewable Energy in Energy-Efficient, Low-Pollution Systems
Sammanfattning : Energy use accounts for the dominating fraction of total sulphur dioxide (SO2), nitrogen oxide (NOx), volatile organic compounds (VOCs) and carbon dioxide (CO2) emissions. In this thesis, different strategies for reducing these emissions are evaluated, using a bottom-up approach. The thesis is divided in two parts. LÄS MER
20. Capturing Swedish Industry Transition towards Carbon Neutrality in a National Energy System Model
Sammanfattning : Industry is responsible for approximately 30 % of the total emissions of greenhouse gases, both globally and in Sweden. Given the climate targets set out in the Paris agreement, the industry is facing a challenging future, requiring effective policies to aid the transition. LÄS MER
