    Sammanfattning : The direct variable costs for heat and electricity production based on solid biomass fuel combustion is approximately 3-5 times lower than the costs in a fossil fuel-oil based boiler in Sweden. In addition waste derived biomass fuels are typically much cheaper than biomass not classified as waste. LÄS MER

    Sammanfattning : The effects of greenhouse gas net emissions on global warming, stricter legislation on waste handling, and the pursuit of ever cheaper heat- and power production are all important factors driving the introduction of complex fuels in incineration plants. However - without fundamental knowledge regarding ash transformation, corrosion control, and materials selection – this introduction of potentially economically and environmentally beneficial fuels, might instead cause economic loss and environmentally adverse effects.

  5. 4. European Energy Policy in Transition: Critical Aspects of Emissions Trading

    Författare :Markus Wråke; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Energy policy; climate policy; carbon dioxide; climate change; emissions trading; EU ETS; efficiency; distributional effects; closures; new entrants; electricity; allocation; auctions; carbon leakage; competitiveness; peat; radiative forcing;

    Sammanfattning : The overarching theme of the thesis is European energy and climate policy, with a particular focus on the role of emissions trading. The thesis consists of eight papers. Paper 1 outlines the origins and characteristics of the European Union’s Emissions Trading System (EU ETS), launched in January 2005. LÄS MER

  7. 5. Gasification-based Biorefinery for Mechanical Pulp Mills

    Författare :Jie He; Per Engstrand; Wennan Zhang; Olof Björkqvist; Christoph Pfeifer; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gasification; Mechanical Pulping; Biofuels; Power Generation; Biomass Residues; ASPEN Plus;

    Sammanfattning : The modern concept of “biorefinery” is dominantly based on chemical pulp mills to create more value than cellulose pulp fibres, and energy from the dissolved lignins and hemicelluloses. This concept is characterized by the conversion of biomass into various bio-based products. LÄS MER
