  1. 11. Bio-LNG and CO2 liquefaction investment for a biomethane plant with an output of 350 Nm3/h : A techno-economic-environmental analysis

    Master-uppsats, Högskolan i Gävle/Energisystem och byggnadsteknik

    Författare :Lars-Julian Vernersson; [2022]
    Nyckelord :Biomethane liquefaction; Carbon dioxide liquefaction; Biogas upgrading; Liquefaction economy; Biomethane life cycle assessment; Biomethane greenhouse gas saving potential; Biomethane emission factor.;

    Sammanfattning : Stricter requirements from the European Union and the German government regarding the utilization of renewable and sustainable fuels for transportation, power, and heat production are currently in effect. This has led to that heavy transportation companies are looking for a more sustainable alternative to liquefied natural gas, such as liquefied biomethane. LÄS MER

  3. 12. Assessing pathways for Net zero emissions in a recycled paper mill

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

    Författare :Laura Marcela Lopez Bonilla; [2022]
    Nyckelord :decarbonisation; net zero emissions; carbon capture and storage; hydrogen; electrification; recycled paper.; avkarbonisering; nettonollutsläpp; avskiljning och lagring av koldioxid; väte; elektrifiering; returpapper.;

    Sammanfattning : It is known that the decarbonization of our economy is crucial for our quest to mitigate climate change and build a sustainable society. Governments are reviewing strategies to eliminate, or at least minimize, the release of carbon emissions into the atmosphere. LÄS MER

  4. 13. Nanoscale characterisation of model Ni-Mo catalyst active phases

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Centrum för analys och syntes

    Författare :Jonas Elmroth Nordlander; [2022]
    Nyckelord :Ni-Mo catalysts; Hydrodeoxygenation; TEM; PXRD; Materials chemistry; Chemistry;

    Sammanfattning : An important stepping stone in transitioning from a fossil-fuel based transportation system is the production of bio-fuels such as bio-oils. For bio-oils to be commercially viable, catalytic upgrading via hydrodeoxygenation is required, typically using Ni-Mo oxide or sulfide catalysts. LÄS MER

  5. 14. Bio versus Mineral Hydraulic Oil in Forklifts : Life Cycle Assessment with Different Waste Scenarios and a Market Analysis

    Master-uppsats, Linköpings universitet/Industriell miljöteknik

    Författare :Maja Hägesten Nilsson; Albin Kylbrink; [2022]
    Nyckelord :;

    Sammanfattning : Hydraulic oils are today most often based on mineral oil and thus eventuate in environmental and climate impacts during all its life cycle phases, but there are bio-based alternatives. Hy- draulic oils are widely used in forklifts, and the use of forklifts is increasing due to logistics within e-commerce. LÄS MER

  7. 15. 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
