  1. 11. Collaborative development of resource efficient district heating in Sweden

    Författare :Sofia Persson; Olof Hjelm; Sara Gustafsson; Mikael Ottosson; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : An increased recovery of excess heat from industrial processes and thermal power generation could significantly reduce energy demands. Industrial excess heat-based district heating systems are generally considered resource efficient because they reduce the use of fossil fuels and the emissions of greenhouse gases. LÄS MER

  2. 12. Utilisation of Excess Heat Towards a Circular Economy : Implications of interorganisational collaborations and strategic planning

    Författare :Sofia Päivärinne; Olof Hjelm; Sara Gustafsson; Jenny Ivner; Kes McCormik; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : In order to significantly lower the environmental impact from human activities, numerous efforts and approaches related to the transformation of human activities have developed during the last decades. Examples of such efforts are policies and strategies at different levels, some with a top-down approach focusing on extensive institutional changes, and some with a bottom-up approach focusing on industrial actors and industry-led activities.

  3. 13. Municipal Energy Planning : Scope and Method Development

    Författare :Jenny Stenlund Nilsson Ivner; Olof Hjelm; Lena Neij; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy planning; energy systems; environmental assessment; decision-making; participation; Other industrial engineering and economics; Övrig industriell teknik och ekonomi;

    Sammanfattning : Swedish municipalities are required to produce a municipal energy plan for their energy supply and use. Whether energy planning is suitable to manage local energy systems, however, is subject to debate. This thesis maps municipal energy planning: the scopes of energy plans and whether goals stated in energy plans are fulfilled. LÄS MER
