  2. 1. Fuel Cells and Biogas

    Author : Lars Hedström; Per Alvfors; Peter Lund; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; air bleed; biogas; carbon dioxide; carbon monoxide; current distribution; dilution; efficiency; energy conversion; energy systems; experimental; fuel cell; fuel cell systems; PEFC; poisoning; reformate; SOFC; Chemical energy engineering; Kemisk energiteknik;

    Abstract : This thesis concerns biogas-operated fuel cells. Fuel cell technology may contribute to more efficient energy use, reduce emissions and also perhaps revolutionize current energy systems. The technology is, however, still immature and has not yet been implemented as dominant in any application or niche market. READ MORE

    Abstract : I kölvattnet av klimatkrisen har det blivit allt tydligare att det fossilbaserade transportsystemet måste genomgå en global omvandling. Många alternativ för förnyelsebara drivmedel har föreslagits, alla omgivna av föreställningar om hur dessa tekniker kommer att bidra till en bättre framtid. READ MORE

  7. 5. Combined Energy Systems Applied to Productive Sectors: The Case of Dairy Farms in Central Bolivia

    Author : Johnny Villarroel-Schneider; Anders Malmquist; Andrew R. Martin; Monica Odlare; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bolivia; polygeneration; trigeneration; productive sector; dairy; biogas; electricity; refrigeration; multiservice; performance; techno-economic; Bolivia; poligeneración; trigeneración; sector productivo; lechería; biogás; electricidad; refrigeración; multiservicio; eficiencia; tecno-económico; Energiteknik; Energy Technology;

    Abstract : Most energy solutions in developing countries focus primarily on solving domestic energy demands of their growing populations without due consideration of sustainable development. On the other hand, in most of these countries, a segment of energy users that has not received enough attention from governments and institutions regarding appropriate energy solutions is the productive sector.
