  1. 1. Techno-economic evaluation of integrated lignocellulosic ethanol production

    Författare :Elisabeth Joelsson; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; distillers dried grain with solubles; biorefinery; modelling; Aspen Plus; biogas; logging residues; spruce; wheat straw; wheat grain; heat; integration; pinch analysis; techno-economic evaluation; first generation; second generation; Ethanol; Lignocellulosic material;

    Sammanfattning : Sweden has claimed that it wants to have a fossil-free vehicle fleet in 2030 as a milestone of its ambitious goal for 2050 to be a country with a sustainable and resource-efficient energy supply without any net GHG emissions. Production of bioethanol from plant materials is one potential method of meeting this goal. LÄS MER

  4. 3. Evaluating the utilisation of industrial excess heat from an energy systems perspective

    Författare :Igor Cruz; Magnus Wallén; Mats Söderström; Maria Johansson; Danica Djuric Ilic; Johanna Mossberg; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial excess heat; Waste heat; Heat recovery; Greenhouse gas emissions;

    Sammanfattning : Sweden aims to achieve climate neutrality by 2045. The need to immediately reduce greenhouse gas emissions in order to achieve climate targets affects industry directly. The pulp and paper sector is responsible for more than 50% of industrial energy use in Sweden. LÄS MER

  5. 4. 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.

  7. 5. 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
