  1. 1. Skalningseffekter av medelstora pölbränder i syrereducerad miljö

    Kandidat-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Tim Hemel; Philip Frenander; [2024]
    Nyckelord :Sökord: syrereducerad atmosfär; medelstora pölbränder; skalningseffekter. Key words: hypoxic air; oxygen reduced atmosphere; medium pool fire; scaling effects; LOC; yields.; Technology and Engineering;

    Sammanfattning : This bachelor's thesis focuses on how scaling the pool diameter affects flammable liquids in an oxygen reduction system (ORS). This topic in the study of pool fire behavior in hypoxic air has been only lightly discussed in previous literature. Therefore, the goal of this thesis work is to further broaden the understanding of hypoxic air. LÄS MER

  3. 2. Navigating Sustainability : A case study exploring alternative energy sources for maritime shipping

    Master-uppsats, KTH/Industriell ekonomi och organisation (Inst.)

    Författare :Simon Nordenskiöld; [2024]
    Nyckelord :Maritime shipping; Alternative energy sources; Alternative fuels; Hydrogen-based fuels; Sustainable shipping; Electrofuels; Electro-methanol; Liquid Hydrogen; Electro-ammonia; Sails; Wind; Technological Innovation System; Sjöfart; Alternativa energikällor; Alternativa bränslen; Vätebaseradebränslen; Hållbar sjöfart; Elektrobränslen; Elektrometanol; Flytande väte; Elektroammoniak; Segel; Vind; Technological Innovation Systems;

    Sammanfattning : This master thesis studies alternative energy sources for maritime shipping in Sweden. With current climate goals, and a need for change, the maritime sector currently undergoes intense transitions. For shipping companies to lower their carbon footprint, the need to replace non decarbonised fuels is hence critical. LÄS MER

  4. 3. Exploring potential E-fuel production pathways for maritime and aviation sectors in France : a techno-economic and environmental assessment

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

    Författare :Mathieu Minaud; [2024]
    Nyckelord :;

    Sammanfattning : The aviation and maritime industries pose significant challenges for decarbonization, having increased activity in the past decade. One promising solution to limit emissions in these sectors is Electrofuels (E-fuel), derived from water electrolysis hydrogen and captured CO2 or nitrogen. LÄS MER

  5. 4. Analysis of fatty acids in fatty acid-based herbicides by gas chromatography

    Master-uppsats, Lunds universitet/Kemiska institutionen

    Författare :Mohamad Abd Elwadood; [2023]
    Nyckelord :Analytical Chemistry; Fatty Acids; Gas Chromatography; Green Herbicides; Retention Index; Flame Ionization Detector; Mass Spectrometry; Supercritical Carbon Dioxide Extraction.; Chemistry;

    Sammanfattning : Fatty acids-based herbicides are considered to be a green alternative to synthesized weed control products. However, the environmentally sustainable effect of those herbicides needs more investigation to be confirmed. LÄS MER

  7. 5. Fuel Transition for Gas Turbines : In a Changing European Energy Landscape

    Master-uppsats, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Lovisa Langerak; [2023]
    Nyckelord :energy technology; gas turbine; energy transition; Europe; green fuels; hydrogen; ammonia; biofuels; energiteknik; gasturbin; energiomställning; Europa; gröna bränslen; vätgas; ammoniak; biobränslen;

    Sammanfattning : The transition to renewable energy sources is vital to mitigate global warming and achieve the climate targets set by the EU. The availability of natural gas in Europe is challenged due to the Russian invasion of Ukraine, leading to a shift towards fossil-free alternatives. LÄS MER
