1. 11. Assessment of existing and potential developments of district-heating systems

   Författare :Elsa Fahlén; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biofuel; external costs; combined heat and power; socio-economic cost-effectiveness; district heating; ExternE; social costs; MARTES; bio transport fuel; biomass gasification;

   Sammanfattning : District heating (DH) may play an important role for achieving the EU goal of a secure, competitive and sustainable energy supply. DH benefits from the possibilities of utilising local resources such as municipal solid waste and other low-quality fuels, as well as low-cost waste heat from industries and from combined heat and power plants (CHP).

   Sammanfattning : Climate concerns and energy security issues have in recent years triggered the interest in biofuels for transport. This has resulted in governmental and intergovernmental targets that, if implemented, will lead to an unprecedented growth in biofuel production. LÄS MER

4. 13. Realise the Potential! : Cost Effective and Energy Efficient District Heating in European Urban Areas

   Författare :Urban Persson; Sven Werner; Louise Trygg; Högskolan i Halmstad; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; District heating; energy efficiency; distribution capital cost; heat density; plot ratio; excess heat recovery; sequential energy supply; heat utilisation; effective width;

   Sammanfattning : The Member States of EU27 need to accelerate the integration of energy efficient technology solutions to reach the 20% energy efficiency target set for 2020. At current pace, projections indicate that only half of expected primary energy reductions will be reached. LÄS MER

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

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

   Sammanfattning : 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. LÄS MER

7. 15. Simulating conditions for combined heat and power in the Swedish district heating sector

   Författare :David Knutsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; System analysis; Combined heat and power; Tradable green certificates; District heating; Tradable emission permits;

   Sammanfattning : The most important issues in the European energy sector today are how toincrease competitiveness on the energy markets, reduce both CO2 emissions anddependence on imported fuels. These issues are also important aspects of Swedish energypolicy. In Sweden, the district heating (DH) sector has commonly been used to achieveSwedish energy policy goals. LÄS MER
