  • Justification of the paper:

    Climate change is one of the greatest and most serious environmental problems of today. To be able stop, or at least slow down the climate changes, it is necessary to reduce the use of fossil fuels and emissions of greenhouse gases. One way of doing this is to replace the fossil fuels with renewable energy and at the same time increase the efficiency of the energy use. One example of a resource efficient way of using energy for heating is district heating which almost exclusively is conducted in a way that generates a low environmental impact. The district heating produced nowadays mostly comes from energy that would otherwise not be useful. Industrial excess heat is one source of energy that can be used within the systems of district heating. District heating systems based on industrial excess heat can save primary energy for district heating companies supplying heat to their heating customers. The use of excess heat is also relevant when it comes to the industrial development at the regional level. Besides the environmental benefits this can also bring economic benefits as well as improved competitiveness of the companies involved.

    This study includes two cases of district heating systems based on excess heat. In both of the cases the development of the district heating systems has been a result of the availability of industrial excess heat from the respective nearby industry. The cases includes interviews with several different relevant respondents representing; the district heating company, the industry providing the excess heat and each municipality in question

    Purpose:

    The purpose of this paper is to investigate how industrial cooperation and mutual exchanges, with a special focus on excess heat, could develop. This is done through a study on the development of district heating in two Swedish communities which both have excess heat based district heating systems.

     

    Research questions

    • What are the main drivers and barriers in the development of excess heat based district heating systems?
    • Which necessary conditions must be provided for excess heat based district heating systems to emerge?

    Theoretical framework:

    The research questions will be analyzed based on the theory of Industrial Symbiosis and have a focus on how industrial collaboration between the district heating companies and the industries arises and develop.

    Results:

    This article will provide knowledge about the development of excess heat based systems of district heating in two different cases.

    Conclusions:

    The results will lead to increased knowledge about the processes behind the development of excess heat based district heating systems, knowledge of the main barriers and drivers behind the development of these types of industrial cooperation’s as well as knowledge of the necessary institutional and organizational conditions which must be provided in order for the industrial cooperation to evolve.
