1. 1. Balancing variable renewable electricity generation using combined heat and power plants, large-scale heat pumps, and thermal energy storages in Swedish district heating systems

   Författare :Svante Monie; Magnus Åberg; Annica Nilsson; Joakim Widén; Magnus Wallén; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; District heating systems; Power-to-Heat; Heat pumps; Combined heat and power; Thermal energy storage; Power balance; Variable renewable electricity; Biomass fuel; Engineering Science with specialization in Civil Engineering and Built Environment; Teknisk fysik med inriktning mot byggteknik och byggd miljö;

   Sammanfattning : The global ambitions to hamper the greenhouse effect has led to ambitious targets for increasing renewable energy use. This, in combination with recent years' vast development of wind and solar power, implies that there will be significant amounts of variable renewable electricity (VRE) in future energy systems.

3. 2. Thermodynamic analysis of Stirling engine systems : Applications for combined heat and power

   Författare :Joseph Adhemar Araoz Ramos; Torsten Fransson; Carlos Augusto Santos Silva; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stirling engine; Thermodynamic analysis; Energiteknik; Energy Technology;

   Sammanfattning : Increasing energy demands and environmental problems require innovative systems for electrical and thermal energy production. In this scenario, the development of small scale energy systems has become an interesting alternative to the conventional large scale centralized plants. LÄS MER

4. 3. From Combined Heat and Power to Polygeneration

   Författare :Fredrik Starfelt; Jinyue Yan; Eva Thorin; Umberto Desideri; Mälardalens högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy- and Environmental Engineering; energi- och miljöteknik;

   Sammanfattning : In order to reach targets on reducing greenhouse gas emissions from fossil resources it is necessary to reduce energy losses in production processes. In polygeneration, several processes are combined to complement each other to avoid sub-optimization of the standalone processes. LÄS MER

5. 4. District Heating and CHP : Local Possibilities for Global Climate Change Mitigation

   Författare :Kristina Difs; G. Björn Karlsson; Louise Trygg; Thomas B. Johansson; Linköpings universitet; []
   Nyckelord :District heating; combined heat and power; carbon dioxide emissions; optimisation; energy policies; TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : Global warming, in combination with increasing energy demand and higher energy prices, makes it necessary to change the energy use. To secure the energy supply and to develop sustainable societies, construction of energy-efficient systems is at the same time most vital. LÄS MER

7. 5. Regional Energy Systems with Retrofitted Combined Heat and Power (CHP) Plants

   Författare :Song Han; Yan Jinyue; Thorin Eva; Deng Shiming; Mälardalens högskola; []
   Nyckelord :Combined heat and power; Waste-to-Energy WtE ; Regional energy system; Greenhouse gases GHG ; Retrofitting; Optimization; Kraftvärme; Avfall-till-Energi; Regionala Energisystem; Växthusgaser; Uppgradering; Optimering.; Energy- and Environmental Engineering; energi- och miljöteknik;

   Sammanfattning : Fossil fuel depletion, economic development, urban expansion and climate change present tough challenges to municipal- and regional-scale energy systems. Regional energy system planning, including waste treatment, renewable energy supply, energy efficiency, and climate change, are considered essential to meet these challenges and move toward a sustainable society.
