  1. 1. Biogas Potential in the North of Sweden : Inventory and Techno-Economic Assessment of Substrates for an Increased Biogas Production in Norrbotten

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Alma Fahlén Hammar; [2023]
    Keywords : Biogas; anaerobic digestion; AD; Norrland; bioenergy; fossil-free; chemical engineering; Chemistry; Technology and Engineering;

    Abstract : 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.

  3. 2. Improved prediction of biogas production at Uddebo wastewater treatment plant : Substrate modelling in SIMCA

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Isak Gullman; [2021]
    Keywords : Anaerobic digestion; Biogas; Industrial waste; Modelling; Sewage sludge;

    Abstract : Anaerobic digestion is a complex process, dependent on multiple factors, which can be made more stable and efficient with the help of process models. A more stable process could reduce biogas torching, which increases the amount of renewable energy available for heat- and electricity production and vehicle fuel. READ MORE

  4. 3. Power-to-Gas and zero-emission buses in Uppsala : challenges and Opportunities from a techno-economic perspective

    University essay from SLU/Dept. of Energy and Technology

    Author : Mårten Rosell; [2021]
    Keywords : Power-to-gas; bränsleceller; medicinsk syrgas; modellering; lönsamhet;

    Abstract : This thesis has explored the use of power-to-gas technology as a means to produce hydrogen for fuel cell electric buses. The municipal council of Uppsala are looking at options to electrify the local city and regional bus fleet but have been faced with power capacity constraints on the local electrical grid. READ MORE

  5. 4. Comparison of mesophilic and thermophilic anaerobic sludge digestion at Hammarby Sjöstadsverk MBR pilot plant for wastewater treatment

    University essay from SLU/Department of Molecular Sciences

    Author : Jessica Sellin; [2021]
    Keywords : Anaerobic digestion; sludge; wastewater treatment; thermophilic; mesophilic; stress test;

    Abstract : Anaerobic digestion is a commonly used method for stabilisation of sewage sludge and production of biogas at municipal wastewater treatment plants (WWTPs). The hydraulic retention time for sludge in the digestion reactors is about 16 days at Henriksdal WWTP in Stockholm. READ MORE

  6. 5. Thermophilic anaerobic digestion of municipal wastewater sludges: A pilot scale evaluation with model assistance

    University essay from KTH/Kemiteknik

    Author : Ted Lundwall; [2021]
    Keywords : Thermophilic anaerobic digestion; Pilot; Municipal wastewater; Biogas; ADM1; Termofil rötning; Pilot; Kommunalt avloppsvatten; Biogas; ADM1;

    Abstract : I takt med att städerna växer ökar belastningen på de kommunala avloppsreningsverken. Käppalaförbundet förutspår att antalet anslutna personekvivalenter till Käppalaverket kommer att öka med över 160 % under de kommande tre decennierna. En ökad belastning leder till en större mängd slam som måste behandlas. READ MORE
