  1. 1. District heating system analysis and challenges within the urban transformation of Kiruna

    Author : Mattias Vesterlund; Jan Dahl; Henrik Saxen; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; District heating; analysis; optimization; design; heat production; Energy Engineering; Energiteknik;

    Abstract : There is currently an ongoing urban transformation in a small Swedish town named Kiruna, it is located in the very north of Sweden well above the Arctic Circle in a sub-arctic climate. Large part of the town will be relocated due to the ground deformation that is caused by the progressing iron ore mining activity and it is affecting all infrastructures of the town. READ MORE

  2. 2. Ion Beam Analysis of First Wall Materials Exposed to Plasma in Fusion Devices

    Author : Per Petersson; Göran Possnert; Anders Hallén; Marek Rubel; Eduardo C. Alves; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ion beam analysis; Microbeam; Plasma wall interaction; Deuterium; Beryllium; Carbon fibre composites; Divertor; Nuclear reaction analysis; Helium-3; Plasma physics with fusion; Plasmafysik med fusion; Ion Physics; Jonfysik;

    Abstract : One major step needed for fusion to become a reliable energy source is the development of materials for the extreme conditions (high temperature, radioactivity and erosion) caused by hot plasmas. The main goal of the present study is to use and optimise ion beam methods (lateral resolution and sensitivity) to characterise the distribution of hydrogen isotopes that act as fuel. READ MORE

    Abstract : Several aspects make today’s transport system non-sustainable: • Production, transport and combustion of fossil fuels lead to global and local environmental problems. • Oil dependency in the transport sector may lead to economical and political instability. READ MORE

  4. 4. Cooperation in local electricity markets : modelling of technical measures

    Author : Maria Andersson; Björn Karlsson; Curt Björk; Tomas Larsson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy system; System cost; Electricity market; Co-operation; Demand-side management; Energy efficiency; Shadow prices;

    Abstract : This thesis presents a system analysis for co-operation in local electricity markets including distributors and customers. The purpose of co-operation is to minimise the system cost of local markets by introducing system measures, such as end-use measures and municipal co-generation plants. READ MORE

  5. 5. On optimization modeling of industrial energy systems at plant level : development of the decision-making tool "MIND"

    Author : Mehrdad Heidari Tari; Björn Kjellström; Linköpings universitet; []
    Keywords : ;

    Abstract : Strategic decisions regarding industrial energy systems should ideally involve the entire plant. Complexity in most industrial systems makes it difficult to gain good insight into how well such systems work. This depends on the number of existing and possible choices. READ MORE
