2. 1. Production planning of CHP plants integrated with bioethanol production and local renewables

   Author : Mahsa Daraei; Eva Thorin; Anders Avelin; Erik Dotzauer; Natasa Nord; Mälardalens högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CHP; Energy systems; Optimization; Polygeneration; Production planning; Renewable resources; Energy- and Environmental Engineering; energi- och miljöteknik;

   Abstract : Production planning of an energy system is dependent on parameters such as energy demand and energy conversion technologies, which are influential in making decisions on operation strategy and optimal performance of the system. In accordance with the European Union energy policy, the share of renewable resources in the energy supply is growing. READ MORE

4. 2. Investigation into sustainable energy systems in Nordic municipalities

   Author : Robert Fischer; Andrea Toffolo; Erik Elfgren; Danica Djuric Ilic; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Renewable energy sources; Nordic municipalities; municipal energy system; electrified transport; biofuels; multi-objective optimization; EnergyPLAN; Energiteknik; Energy Engineering;

   Abstract : Municipal energy systems in Nordic environments face multiple challenges: the cold climate, large-scale industries, a high share of electric heating and long distances drive energy consumption. While actions on the demand side minimize energy use, decarbonization efforts in mining, industries, the heating and the transport sector can increase the consumption of electricity and biofuels.

5. 3. Energy and Environmental Factors in Food and Beverage Production Systems : An Analysis of Tomatoes, Whisky, and Beer

   Author : Daniel Danevad; Karl Hillman; Ola Eriksson; Hanna Tuomisto; Högskolan i Gävle; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; environmental systems analysis; waste management; import; local resources; food production; beverage production; circularity; Hållbar stadsutveckling; Sustainable Urban Development;

   Abstract : Given the anticipated global population of approximately 10 billion by 2050, the task of ensuring adequate sustenance for all within the constraints of Earth's limited resources presents a significant challenge. The production of food and beverages demands considerable energy investment, as well as other essential resources such as water and nutrients. READ MORE

6. 4. A Gap in the Grid : Attempts to introduce natural gas in Sweden 1967-1991

   Author : Anna Åberg; Arne Kaijser; Per Högselius; Erland Mårald; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; natural gas; energy policy; infrastructure planning; history of technology; Sweden; Northern Europe; risk; project planning; Denmark; Norway; Soviet Union; Germany; energy systems; energy history; fossil fuels;

   Abstract : This thesis follows the process of introducing natural gas in Sweden and the construction of a Northern European gas grid from 1967 to 1991. Natural gas is a relatively unnoticed fuel in Sweden today, but this relative anonymity stands in contrast to an extensive historical activity that has taken place behind the scenes of Swedish energy policy.

7. 5. Prospects for Bioenergy in Europe - Supply, Demand and Trade

   Author : Karin Ericsson; Miljö- och energisystem; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiforskning; Energy research; biofuel trade; perennial energy crops; co-firing; bioenergy policy; biomass production cost; potential biomass supply; Bioenergy; Europe;

   Abstract : Renewable energy sources (RES), such as biomass, can be used to address two important issues in Europe: climate change and energy security. If biomass is produced sustainably and used efficiently, bioenergy contributes very little to CO2 emissions. READ MORE
