1. 26. Plan and Reality : Municipal Energy Plans and Development of Local Energy Systems

   Författare :Jenny Stenlund Nilsson Ivner; Anders Mårtensson; Bengt Johansson; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; municipal energy planning; energy management; energy systems; systems; renewable energy; energy conservation; municipality; local authority; Environmental engineering; Miljöteknik;

   Sammanfattning : Enligt lagen om kommunal energiplanering ska varje svensk kommun ha en energiplan för tillförsel för tillförsel och användning av energi. Huruvida energiplanering är ett bra sätt att styra det kommunala energisystemet är dock omdebatterat. LÄS MER

3. 27. On the road to climate neutral Swedish transportation: Energy system modelling to support the transition at national, regional, and local levels

   Författare :Jonas Forsberg; Anna Krook-Riekkola; Andrea Toffolo; Åsa Lindman; Hannah E. Daly; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy transition; Energy system modelling; TIMES-City; TIMES-Sweden; Transportation; Decarbonisation; Climate mitigation; Energiteknik; Energy Engineering;

   Sammanfattning : Transportation is a critical pillar of modern society. Over the past decades, growth in mobility of people and goods have been both enabled by and dependent upon fossil fuels. Strong action is needed to break this dependence in order to reduce CO2. LÄS MER

4. 28. Renewable Energy in Energy-Efficient, Low-Pollution Systems

   Författare :Bengt Johansson; Miljö- och energisystem; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hydrogen; ethanol; methanol; rape methyl ester; biomass; renewable energy; cogeneration; energy efficiency; scenarios; air pollution; carbon dioxide; Environmental technology; pollution control; Miljöteknik; kontroll av utsläpp;

   Sammanfattning : Energy use accounts for the dominating fraction of total sulphur dioxide (SO2), nitrogen oxide (NOx), volatile organic compounds (VOCs) and carbon dioxide (CO2) emissions. In this thesis, different strategies for reducing these emissions are evaluated, using a bottom-up approach. The thesis is divided in two parts. LÄS MER

5. 29. Supermarket refrigeration systems for demand response in smart grids

   Författare :Tommie Månsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Supermarket; Demand-side management; Smart-Grid; Energy efficiency; Food retail; Demandresponse; Thermal modelling; Refrigerated Display Cabinet; Renewable energy;

   Sammanfattning : With an increasing share of intermittent renewable energy sources in the electrical grid, the need for adapting the demand to the available supply of electricity becomes increasingly important. Within this thesis, the demand response capacity by supermarket refrigeration systems are investigated and methods for enabling it is developed. LÄS MER
