  1. 1. Optimization of an energy system in rural Thailand

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

    Författare :Axel Lund; Mattias Malmberg; [2023]
    Nyckelord :Rural energy; Thailand; Microgrid; Biomass; Solar PV; Sustainable development goals; Minor field study; stand-alone; HOMER pro; Landsbyggdens energi; Thailand; Microgrid; Biomassa; Solceller; Hållbara utvecklingsmål; Minor field study; fristående energi system; HOMER pro;

    Sammanfattning : By 2020, Thailand ensured 100% electricity access to its 72 million inhabitants. This was partly done by promoting off-grid energy systems in rural areas instead of using costly grid extensions. LÄS MER

  3. 2. 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

  4. 3. 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.
