Sammanfattning : Abstract The thesis aims at providing a better understanding of public policy instruments used in policy-making within the energy sector, particularly regarding their role in the change towards an increased use of renewable energy sources for generation of electricity. The research was guided by an underlying assumption that a markedly higher proportion of the energy generated from renewable sources can be considerably enhanced by use of policy instruments that support the development and the market creation of new, renewable energy technologies.

Sammanfattning : The importance of access to modern energy has been well understood by governments and donor agencies in many developing countries, and significant effort has been made in recent years to address energy access challenges. However, despite these efforts, the International Energy Agency (IEA) has predicted that the energy access problem will remain unresolved by 2030. LÄS MER
3. 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
4. Fuel conversion and ash formation interactions : a thermochemical study on lignocellulosic biomass
Sammanfattning : Biomass is considered to be CO2 neutral, and to be able to reduce the dependency on fossil fuels the need for expanded and sustainable biomass feedstock is increasing. Ash-related problems are some of the most important aspects of this increasing use of new biomass assortments in thermal energy conversion systems. LÄS MER
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
