  1. 6. Potential of local producing bioenergy/biogas from waste in the municipality of Ragunda

    Kandidat-uppsats, Mittuniversitetet/Institutionen för naturvetenskap, design och hållbar utveckling (2023-)

    Författare :Tomás Hayes; [2023]
    Nyckelord :Bioenergy; Biogas; Biomethane; Global Warming Potential; Rural development;

    Sammanfattning : Population growth, climate change and increased global energy demand has led to the search for environment friendly energy sources. Ragunda Municipality’s major producers of Greenhouse Gas (GHG) emissions are transport, agriculture, and work machines. LÄS MER

  3. 7. Production and analysis of novel disulfide variants of Subtilisin Carlsberg

    Master-uppsats, Linköpings universitet/Kemi

    Författare :Anton Elfstrand; [2023]
    Nyckelord :Subtilisin Carlsberg; Disulfide; Protein Engineering; Kinetic Stability;

    Sammanfattning : Protein engineering has been used to alter the stability of proteins for several decades withmuch success, one approach being to introduce two cysteine residues that together form adisulfide bridge. The disulfide bridge can increase the Gibbs free energy of the transitionstate, thus increasing energy difference between the folded state and the unfolding transitionstate, leading to increased kinetic stability of the protein.

  4. 8. A changing energy security environment – a review of alternative energy carriers for light duty vehicles

    Master-uppsats, Försvarshögskolan

    Författare :Julia Nilsson; [2023]
    Nyckelord :Supply chain; Logistic; Energy security; Light duty vehicle;

    Sammanfattning :   The increasing energy demand and its impact on the climate around the world has evoked several sectors´ efforts in order to develop and implement sustainable technologies. Political incentives and companies go toward great changes when it comes to reduction of energy sources from fossil-origins in order to reduce greenhouse gas emissions and achievement of energy security.

  5. 9. An Environmental (LCA) and economic assessment (LCC) of on-farm and centralized alternatives for biogas production for two Swedish farms in Götene

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Abdelali Ouakrim; [2023]
    Nyckelord :Life cycle assessment; LCA; life cycle costing; LCC; biogas; animal manure; biogas production; co-digestion;

    Sammanfattning : Biogas production through anaerobic digestion is an important part towards the achievement of a bio-based and circular economy in Sweden. In fact, Swedish government proposed a strategy suggesting that biogas production should be increased from 2 TWh today to 7 TWh by 2030. LÄS MER

  7. 10. Biogas Potential in the North of Sweden : Inventory and Techno-Economic Assessment of Substrates for an Increased Biogas Production in Norrbotten

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Alma Fahlén Hammar; [2023]
    Nyckelord :Biogas; anaerobic digestion; AD; Norrland; bioenergy; fossil-free; chemical engineering; Chemistry; Technology and Engineering;

    Sammanfattning : Great investments are planned in the north of Sweden the coming years, not the least in the county of Norrbotten where the projects collectively are referred to as the green transition due to the focus on fossil-free techniques. But to be able to secure a sustainable energy supply and reach the goal set by the member states of the European Union of a carbon dioxide neutral union in 2050 the production of alternative energy sources needs to intensify.
