  1. 1. Greenhouse gas emissions and energy efficiency of various renewable energy pathways in the truck industry : An LCA and energy efficiency analysis on fuel production for and manufacturing of 40 tonne heavy trucks in Sweden

    Master-uppsats, Linköpings universitet/Institutionen för tema; Linköpings universitet/Filosofiska fakulteten

    Författare :Jacob Axell; [2023]
    Nyckelord :Hydrogen; Sweden; 40-tonne haulage truck; LCA; Wind energy; Bio fuel; Energy efficiency; CO2 emissions;

    Sammanfattning : This study focuses on assessing the greenhouse gas emissions and energy efficiency of 40-tonne haulage trucks in fuel production and manufacturing in a Swedish context. The aim was to provide accurate greenhouse gas accounting and evaluate the contribution to mitigating climate change. LÄS MER

  3. 2. Finding ways to develop a sustainable bioeconomy: The case of industrial cassava in Colombia : Environmental impact and food security insights from a combined life cycle assessment and interview study

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

    Författare :Isabel Nilsson Alarcón; [2023]
    Nyckelord :industrial cassava; food security; land use; climate change; biodiversity loss; sustainable bioeconomy; Life Cycle Assessment LCA ; Colombia; industriell kassava; tryggad livsmedelsförsörjning; markanvändning; klimatförändring; minskad biodiversitet; hållbar bioekonomi; livscykelanalys LCA ; Colombia;

    Sammanfattning : Cassava has been identified as a potential key crop for a sustainable bioeconomy in Colombia.However, the bioeconomy is not inherently sustainable, and neither is producing cassava,which makes research on it crucial. Increasing biomass circularity could be key for increasingthe cassava industry’s sustainability performance. LÄS MER

  4. 3. 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

  5. 4. Klimatpåverkan och energianvändning vid tillämpning av bio-CCS och bio-CCU från biogasanläggningar

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Energy and Technology

    Författare :Emelie Wallman; [2022]
    Nyckelord :livscykelanalys; koldioxid; biometan; power to gas; biologisk metanisering; katalytisk metanisering; elektrolys;

    Sammanfattning : To mitigate the human-induced climate change, Sweden has adopted a climate policy framework that states a net-zero emissions of greenhouse gases by the year of 2045 and thereafter negative emissions. To achieve this goal extensive emission mitigation alongside supplementary measures are required. LÄS MER

  7. 5. Climate impact of bioH2 production from biogas using CO2 mineralization for carbon capture and storage

    Kandidat-uppsats, SLU/Dept. of Energy and Technology

    Författare :Hera Harðardóttir; [2022]
    Nyckelord :carbon capture and storage; carbon dioxide mineralization; biohydrogen production; global warming potential; greenhouse gases;

    Sammanfattning : Carbon dioxide (CO2) concentrations in the atmosphere are increasing and are now higher than they have ever been, mostly because of CO2 released from burning fossil fuels for energy. Global energy demand will continue to rise in the future, resulting in increased carbon emissions. LÄS MER
