  1. 1. Techno-Economic Assessment of High-Temperature H2O/CO2 : Co-Electrolysis in Solid Oxide Electrolysers for Syngas Production

    Master-uppsats, KTH/Kemiteknik

    Författare :Shivani Ramprasad Jambur; [2022]
    Nyckelord :Co-electrolysis; Power-to-X; Process modeling; Green Syngas; Solid-Oxide Electrolyser;

    Sammanfattning : High-temperature Co-electrolysis of H2O and CO2 in a solid-oxide electrolyser (Co-SOE) for syngas production is a high-efficiency renewable electricity conversion and storage method part of the Power-to-X technologies. Syngas, a mixture of H2, CO and CO2, is a critical building block to make several chemical and synthesis fuels. LÄS MER

  3. 2. Techno economic assessment of CCUS for a biogas facility in Sweden : Evaluating the economic feasibility for three CCUS concepts

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Tobias Johansson; Markus Knutsson; [2022]
    Nyckelord :CCS; CCU; CCUS; Biogas; Biologic methanation; Negative emissions; TEA; Techno economic assessment.;

    Sammanfattning : Many countries strengthen their commitments to reduce greenhouse gas emissions to limit climate change and meet the Paris Agreement (Masson-Delmotte et al., 2019). Commitments include achieving net-zero emissions or in some cases even negative emissions (Government offices of Sweden, 2020a; United Nations, 2021a). LÄS MER

  4. 3. 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

    Sammanfattning : حظيت البدائل المتجددة باهتمام كبير في ظل انخفاض موارد الوقود الاحفوري المتاحة وزيادة المتطلبات البيئية. ان انتاج المواد الكيميائية والوقود المتجدد من خلال استغلال الكتلة الحيوية يقدم طريقا واعدا لدفع هذا التحول الى الامام. LÄS MER

  7. 5. System concept for small-scale biological methanation using electrolysis and trickle bed reactor : with the aim of upgrading biogas to vehicle fuel quality

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

    Författare :Gustav Larsson; [2021]
    Nyckelord :biological methanation; biogas upgrade; methane; small-scale methanation;

    Sammanfattning : In the present study, the concept of a biological H2 methanation (BHM) system was created for four cases of scale which are determined by electrolyser scale. The system design is aimed to upgrade existing biogas to vehicle fuel quality, with a concentration of CH4 above 95% and H2S removal. The cases of scale and type of electrolyser are: 4. LÄS MER
