  3. 3. Green consumption energy use and carbon dioxide emission

    Detta är en avhandling från Umeå : Kulturgeografi

    Författare :Eva Alfredsson; Umeå universitet.; [2002]
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Social and economic geography; Energy consumption; Carbon dioxide emission; Energy intensity; Carbon intensity; Life cycle assessment; Consumption patterns; Lifestyles; Systems analysis; Microsimulation modelling; Demography; Sustainability; Rebound effects; Substitution effects; Kulturgeografi; SOCIAL SCIENCES Business and economics Human geography; economic geography Human geography; SAMHÄLLSVETENSKAP Ekonomi Kulturgeografi; ekonomisk geografi Kulturgeografi; Social and Economic Geography; kulturgeografi;

    Sammanfattning : The aim of this thesis is to explore the quantitative potential to reduce energy requirements and CO2 emissions through changed patterns of consumption, given unchanged levels of consumption expenditure. The thesis question is analysed using a systems analysis approach which in this case means that life cycle assessment data on energy requirements and CO2 emissions related to household consumption are combined with a financial and behavioural analysis to make sure that the budget constraint is kept and that both the first and second order effects of adopting a green consumption pattern are analysed.

  4. 4. On direct hydrogen fuel cell vehicles modelling and demonstration

    Detta är en avhandling från Stockholm : KTH

    Författare :Kristina Haraldsson; KTH.; [2005]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical engineering; direct hydrogen; Proton Exchange Membrane; PEM; fuel cell; fuel cell vehicle; fuel cell hybrid vehicles; on-board hydrogen storage; Kemiteknik; TECHNOLOGY Chemical engineering; TEKNIKVETENSKAP Kemiteknik;

    Sammanfattning : In this thesis, direct hydrogen Proton Exchange Membrane (PEM) fuel cell systems in vehicles are investigated through modelling, field tests and public acceptance surveys.A computer model of a 50 kW PEM fuel cell system was developed. The fuel cell system efficiency is approximately 50% between 10 and 45% of the rated power. LÄS MER
