  1. 1. Biomass in a Sustainable Energy System

    Författare :Pål Börjesson; Miljö- och energisystem; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; kontroll av utsläpp; Miljöteknik; pollution control; Environmental technology; economic valuation; environmental impact; carbon dioxide; Biomass; energy efficiency; Energiforskning; Energy research;

    Sammanfattning : The increased use of biomass for energy is as a key strategy in reducing carbon dioxide (CO2) emission, which represents the largest anthropogenic contribution to the greenhouse effect. In this thesis, aspects of an increase in the utilisation of biomass in the Swedish energy system are treated. LÄS MER

  3. 2. Renewable Energy in Energy-Efficient, Low-Pollution Systems

    Författare :Bengt Johansson; Miljö- och energisystem; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hydrogen; ethanol; methanol; rape methyl ester; biomass; renewable energy; cogeneration; energy efficiency; scenarios; air pollution; carbon dioxide; Environmental technology; pollution control; Miljöteknik; kontroll av utsläpp;

    Sammanfattning : Energy use accounts for the dominating fraction of total sulphur dioxide (SO2), nitrogen oxide (NOx), volatile organic compounds (VOCs) and carbon dioxide (CO2) emissions. In this thesis, different strategies for reducing these emissions are evaluated, using a bottom-up approach. The thesis is divided in two parts. LÄS MER

  4. 3. Corporate and city GHG inventories : Impact on global CO2 emissionswhen considering electricity and CHP-based district heating

    Författare :Lena Nordenstam; Björn Karlsson; Louise Ödlund; Danica Djuric Ilic; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : One initiative to reduce greenhouse gas (GHG) emissions involves developing standards for GHG inventories. Companies and cities (regions) can use GHG inventories to compile and report their GHG emissions. LÄS MER

  5. 4. Economic growth, energy consumption and CO2 emissions in Sweden 1800-2000

    Författare :Astrid Kander; Ekonomisk-historiska institutionen; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; energy intensity; Environmental Kuznets Curve; relative price analyses; standard calculations; technical change; structural changes; energy quality factors; consumers surplus; Social and economic history; forest management; CO2 intensity; Ekonomisk och social historia;

    Sammanfattning : Large transformations of technologies have occurred in the Swedish economy during the last two centuries, resulting in higher income, better quality of products and changing composition of GDP. An agrarian society has given way to an industrial society and lately to a post-industrial phase. LÄS MER

  7. 5. Speeding up the Atmosphere : Experimental oxidation studies of ambient and laboratory aerosols using a flow reactor

    Författare :Erik Ahlberg; MERGE: ModElling the Regional and Global Earth system; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Secondary organic aerosols; oxidation flow reactor; volatile organic compounds; climate;

    Sammanfattning : Apart from gases, the air we breath consist of tiny, so called, aerosol particles. A cubic metre of air in a relatively clean environment can consist of several billion aerosol particles. The impact of these particles on human health and on climate is significant. LÄS MER
