  1. 11. Techno-economic Comparison of Three Electrified Hydrogen Production Technologies in The Context of Sweden

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

    Författare :Pingping Tao; [2023]
    Nyckelord :ESMR; Water Electrolysis; LCOH; Grid; Decentralized; Sensitivity; Wind; PV;

    Sammanfattning : Hydrogen, as a dense energy carrier with low carbon footprint, will play an important role in energy transition. It only produces water after reaction which is totally environment friendly. There are many different technologies for hydrogen production. LÄS MER

  3. 12. Assessing the Benefits of Fossil-Free Gas Turbines in Distribution Networks : A Case Study in Västerås

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

    Författare :Fredrik Hansell; Axel Vällfors; [2023]
    Nyckelord :Gas turbine; power system stability; balancing markets; hydrogen; eMethanol; Gasturbin; kraftsystemstabilitet; balansmarknader; vätgas; e-metanol;

    Sammanfattning : As the share of weather-dependent renewable electricity production increases, the demand for power system flexibility grows. In the Swedish power system, gas turbines have historically been utilised for back-up power generation. LÄS MER

  4. 13. 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

  5. 14. Optimization of a two-step anaerobic treatment of wastewater from the Pulp and Paper Industry

    Master-uppsats, KTH/Industriell bioteknologi

    Författare :Sara Bard; [2022]
    Nyckelord :Wastewater treatment; biogas; methane; pulp and paper mill wastewater; wood raw material; anaerobic treatment; sulphate reduction; UAPB reactor; Vattenrening; biogas; metan; processvatten från pappers- och massaindustrin; träråvara; anaerob rening; sulfatreduktion; UAPB reaktor;

    Sammanfattning : Under de senaste 30 åren så har antalet massa- och pappersbruk minskat medan den totala produktionen av massa och papper har ökat. En högre produktion per bruk tillsammans med en hårdare miljölagstiftning, sätter ett högre tryck på vattenreningen på varje bruk. 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
