1. 11. Biofuels from Kraft Black Liquor : Pilot-Scale Gasification Development and Techno-Economic Evaluation of Industrially Relevant Biofuel Production Pathways

   Författare :Yawer Jafri; Erik Furusjö; Ilkka Hannula; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biofuels; black liquor; pyrolysis oil; gasification; drop-in; energy systems; techno-economic; Energiteknik; Energy Engineering;

   Sammanfattning : Fuel combustion for transport was responsible for 24% of EU-28 greenhouse gas (GHG) emissions in 2016. Member states are expected to ensure that the share of renewable energy in the transport sector is at least 14% by 2030. Some countries, such as Sweden, have more ambitious targets. LÄS MER

3. 12. Investigation into sustainable energy systems in Nordic municipalities

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

   Sammanfattning : 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.

4. 13. A discrete-event simulation approach to improve efficiency in stump fuel supply chains

   Författare :Anders Eriksson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Current concerns about climate change and fossil fuel dependency have intensified interest in renewable energy and increased demand for sustainable alternatives. Softwood tree stumps could be a very interesting renewable fuel assortment. The stump-root system constitutes about 25% of stem volume. LÄS MER

5. 14. Future District Heating Interactions – Modelling Impacts of Industrial Excess Heat Utilisation and Energy Efficient Buildings

   Författare :Akram Sandvall; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fourth generation district heating; TIMES; waste heat; urban planning.; dynamic energy system modelling; MARKAL; passive houses; low-energy buildings; excess heat;

   Sammanfattning : International goals for climate change mitigation plus energy security targets could be met cost-effectively by interactions between different parts of energy systems. The fourth generation of the district heating systems concept was developed as an attempt to accelerate district heating (DH) systems’ interactions with other energy systems. LÄS MER

7. 15. Decentralization in the electricity system: At the household, community and city levels

   Författare :Verena Heinisch; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Smart city; Storage systems; Power-to-heat; Optimization; Energy system modeling; Photovoltaic; Decentralization; Community energy; Prosumers;

   Sammanfattning : Recent years have seen a rise in the number of implementations of small-scale generation and storage technologies for electricity and heat at different levels in the energy system. This trend towards decentralization of the system is driven by rapid decrease in technology costs, as well as the intentions expressed by various stakeholders to contribute to a carbon-neutral energy system.
