11. The potential of industrial hemp (Cannabis sativa L.) for biogas production
Sammanfattning : Biofuels are currently produced from agricultural crops, and an increasing use of crops for this application is expected in the EU in the years to come. The dominating crops cultivated in the EU for biofuel production today have a relatively large environmental impact. LÄS MER
12. Land-Use and Climate Effects of Bioenergy: Carbon balances of Swedish forest bioenergy systems – and – Geospatial biomass supply-and-demand matching for Europe
Sammanfattning : In order to keep global warming below 2 degrees Celsius, greenhouse gas emissions have to be drastically reduced. Bioenergy can play a role in climate change mitigation by substituting for energy from fossil fuels; however, biomass is a limited resource associated with emissions from land use and land-use change.

13. Regional Energy Systems with Retrofitted Combined Heat and Power (CHP) Plants
Sammanfattning : Fossil fuel depletion, economic development, urban expansion and climate change present tough challenges to municipal- and regional-scale energy systems. Regional energy system planning, including waste treatment, renewable energy supply, energy efficiency, and climate change, are considered essential to meet these challenges and move toward a sustainable society.

14. Numerical Simulation of Combustion and Gasification of Biomass Particles
Sammanfattning : In this thesis, a numerical approach is adopted to study biomass thermochemical conversion. Detailed physical and chemical processes involved in the thermochemical conversion of biomass are considered. LÄS MER
15. An agent-based approach to supply side modeling of agricultural and power systems
Sammanfattning : This thesis deals with the modeling of economic systems in the context of agricultural and power systems, and some aspects of the difference between the standard economics equilibrium approach and the agent-based approach. We model the supply side, where agents make decisions on what to produce or in what to invest. LÄS MER
