21. Heat demand profiles of buildings' energy conservation measures and their impact on renewable and resource efficient district heating systems
Sammanfattning : Increased energy performance of the building stock of European Union is seen as an important measure towards mitigating climate change, increasing resource utilisation efficiency and energy supply security. Whether to improve the supply-side, the demand-side or both is an open issue. LÄS MER
22. Fine particle emissions and slag formation in fixed-bed biomass combustion : aspects of fuel engineering
Sammanfattning : There is a consensus worldwide that the share of renewable energy sources should be increased to mitigate climate change. The strive to increase the renewable energy fraction can partly be met by an increased utilization of different biomass feedstocks. LÄS MER
23. Chemistry and Process Design of Integrated Removal of Nitrogen and Sulfur oxides in Pressurized Flue Gas Systems
Sammanfattning : Carbon capture and storage is vital to reach the climate goals to limit the increase in the global temperature. Among the carbon capture technologies, oxy-fuel and chemical looping combustion produce a stream mainly containing carbon dioxide (CO2) and water but also contaminants such as nitrogen oxides (NOx) and sulfur oxides (SOx).

24. Urban Building Energy Modeling for Retrofit Scenarios : Development, Calibration, Validation and Implementation for Swedish Residential Buildings
Sammanfattning : The necessity for an accelerated transition of urban energy systems and, in particular, the building sector toward energy efficiency and carbon neutrality poses new challenges to planning and retrofitting existing buildings. To cope with these challenges, so-called urban building energy models (UBEMs) have been introduced for quantifying the energy demand in the building sector, identifying the hot spots of energy use and suggesting scenarios for retrofitting the buildings.

25. Bio-SNG from Thermal Gasification - Process Synthesis, Integration and Performance
Sammanfattning : Biomethane or synthetic natural gas (Bio-SNG) produced from gasified renewable woody biomass is a promising option for replacing fossil natural gas. The complete interchangeability with natural gas in all its conventional applications such as in the power generation, transportation and chemical industry sector is of particular interest. LÄS MER
