21. Fluidized bed plants for heat and power production in future energy systems
Sammanfattning : Fluidized bed (FB) plants are used for heat and power production in several energy systems around the world, with particular importance in systems using large shares of renewable solid fuel, e.g., biomass. LÄS MER
22. Carbon in Boreal Streams : Isotopic Tracing of Terrestrial Sources
Sammanfattning : The boreal biome comprises vast areas of coniferous forests, dotted with millions of peatlands. Plants harbouring these ecosystems fix CO2 from the atmosphere, which is later incorporated into the vegetation biomass and subsequently buried in soils. LÄS MER
23. Climate Impact and Energy Balance of Emerging Biorefinery Systems
Sammanfattning : Use of fossil fuels is the main contributor to anthropogenic emissions of greenhouse gases (GHG). Biorefineries, which are facilities that produce a set of valuable products from biomass, have been suggested as alternatives to fossil refineries, for the production of fuels, chemicals and materials.

24. A Methodology for Identifying Transformation Pathways for Industrial Process Clusters: Toward Increased Energy Efficiency and Renewable Feedstock
Sammanfattning : The European process industry is facing major challenges. Modern, large-scale production facilities in other parts of the world are often more efficient. Furthermore, limited access to inexpensive shale gas from North America has led to an additional disadvantage for the European industry. LÄS MER
25. Climate impacts of woody biomass use for heat and power production in Sweden
Sammanfattning : Global warming is a result of human-induced greenhouse gas emissions, primarily from fossil fuel use, but also from land use changes. To mitigate climate change, fossil fuel-based energy systems need to be replaced with alternative energy sources. LÄS MER
