1. 1. 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

3. 2. 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

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

5. 4. 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

7. 5. Climate impact of hydrogen as fuel for the heavy road transportation : A time-dependent life cycle methodology based assessment

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

   Författare :Madeleine Stolpe; [2021]
   Nyckelord :hydrogen production; steam methane reforming; carbon capture and storage; waterelectrolysis; heavy trucks;

   Sammanfattning : Currently, the transportation sector stands for one third of all greenhouse gas emissions in Sweden. Hydrogen (H2) could contribute to a decarbonized transportation sector since water is the only direct emission from a fuel cell electric vehicle. LÄS MER
