    Sammanfattning : In industry today there are increasing demands not only on product performance, but also on environmental performance. In striving to develop high performance environmentally adapted products, optimization of product life is a central issue. LÄS MER

  4. 13. Building Sustainable Batteries : Organic electrodes based on Li- and Na-benzenediacrylate

    Författare :Alina Oltean; Daniel Brandell; Leif Nyholm; Steven Renault; Martin Sjödin; Robert Dominko; Uppsala universitet; []
    Nyckelord :Organic Electrode Materials; Li-ion Batteries; Na-ion Batteries; Calendaring; Recycling Process; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

    Sammanfattning : As possible alternatives to the conventional inorganic Li- or Na-ion battery electrode materials, organic compounds have recently drawn considerable attention. However, major challenges such as poor electronic conductivity, solubility in battery electrolyte or fast capacity decay of the resulting electrochemical cells are some of the reasons that hold these compounds back from becoming commercial solutions in the energy system.

  5. 14. Low-temperature Heating in Existing Swedish Residential Buildings : Toward Sustainable Retrofitting

    Författare :Qian Wang; Sture Holmberg; Natasa Nord; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Retrofitting; Low-temperature heating; Energy efficiency; Sustainability; Swedish residential buildings; Renovering; Lågtemperatursuppvärmning; Energieffektivitet; Hållbarhet; Svenska bostadsbyggnader; Energy Technology; Energiteknik;

    Sammanfattning : As an energy-efficient alternative in cold climate countries such as Sweden, low-temperature heating (LTH) technology has shown promising advantages and shortcuts to contribute to the efficiency of heat supply, as well as to the overall sustainability of building performance. The goal of this thesis is to contribute to the development of methodologies and modeling tools to support sustainable retrofitting in the Swedish housing stock. LÄS MER

  7. 15. System studies of biogas production : comparisons and performance

    Författare :Emma Lindkvist; Magnus Karlsson; Mats Söderström; Maria Johansson; Ola Norrman Eriksson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Biogas has the potential to be part of the transition towards a more sustainable energy system. Biogas is a renewable energy source and can play an important role in modern waste management systems. Biogas production can also help recirculate nutrients back to farmland. LÄS MER
