  2. 21. Lignocellulosic Ethanol Production Potential and Regional Transportation Fuel Demand

    Author : Lilia Daianova; Jinyue Yan; Louise Trygg; Mälardalens högskola; []
    Keywords : Agricultural by-products; Straw; Bioethanol; Transport system; Greenhouse gases GHG ; Polygeneration system; Combined Heat and Power CHP ; Mixed Integer Programming MIP .; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : Road traffic dominates in domestic Swedish transportation and is highly dependent on fossil fuels, petrol and diesel. Currently, the use of renewable fuels in transportation accounts for less than 6% of the total energy use in transport. READ MORE

  4. 22. District Heating Sensitivity to Heat Demand Reductions and Electricity Market Dynamics

    Author : Magnus Åberg; Ewa Wäckelgård; Dag Henning; Joakim Widén; Louise Trygg; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk fysik; Engineering Science;

    Abstract : Sweden and the rest of the EU member states have to reduce primary energy use andemissions of CO2, and increase the use of renewable energy sources according to the EUclimate change package “20-20-20”. To do this, the energy systems need to use less fossilfuel and to utilise energy resources more efficiently. READ MORE

  5. 23. Biobased Combined Heat and Power Production in Sweden – Opportunities for and Challenges to Sustainability from the Plant Operator Perspective

    Author : Malin Pettersson; Miljö- och energisystem; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; District heating; Biobased economy; Decarbonisation; Combined heat and power plant; Sustainability;

    Abstract : Although combined heat and power (CHP) production in Sweden is already largely decarbonised, this technology has further potential to alleviate pressing environmental concerns. Today, biobased CHP plants connected to district heating (DH) grids dominate the Swedish residential heating sector. READ MORE

  6. 24. Heat transfer in falling film evaporation of black liquor - Experiments and theory

    Author : Miriam Johansson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; evaporator; black liquor; falling film; kraft pulp mill; Heat transfer; evaporation; viscosity; correlations; experimental; non-Newtonian;

    Abstract : Pulp and paper industry uses a large part of the total amount of energy in industry in Sweden. The evaporation plant has the major energy demand in the kraft pulp mill, which is the dominant type of chemical pulp mill. Previous studies have shown potential to decrease the live steam demand for the pulp process, e.g. READ MORE

  7. 25. Externally fired gas turbine cycle based on biomass gasification gas as fuel

    Author : Fabiola Baina Veizaga; Torsten Fransson; Lasse Rosendhal; KTH; []
    Keywords : Externally fired micro gas turbine; heat transfer; combustion of biomass derived gas; micro combined heat and power; Energiteknik; Energy Technology;

    Abstract : Energy services are essential for the development of societies, reduce poverty, and improve the living standards of inhabitants. The conventional routes to provide energy services employ fossil fuels. However, this involves environmental and availability concerns. READ MORE
