  1. 1. 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

  3. 2. Investigating the dynamics between the developing Nordic hydrogen market and the electricity system under uncertainty

    Master-uppsats, KTH/Energiteknik

    Författare :Timon Renzelmann; [2024]
    Nyckelord :energy modelling; energy storage; global sensitivity analysis; hydrogen; Method of Morris; Nordics; OSeMOSYS; uncertainty analysis; energimodellering; energilagring; global känslighetsanalys; vätgas; Morris-metoden; Nordiska länder; OSeMOSYS; osäkerhetsanalys;

    Sammanfattning : The potential of hydrogen as a clean energy carrier is hotly debated, but it promises to significantly contribute to a sustainable energy future. Hydrogen can replace fossil fuels in carbon-intensive industries, heavy transport and aviation, and support a renewable energysystem by acting as energy storage to balance intermittent supply.

  4. 3. TECHNOLOGICAL ASSESSMENT OF HYDROGEN (FUTURE SCENARIOS: SOCIOLOGICAL, ENVIRONMENTAL, ECONOMIC, AND ENERGETIC ASPECTS)

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Arturo Martínez Lozano; [2023-03-08]
    Nyckelord :;

    Sammanfattning : Nowadays, the term energy transition is coming into vogue, as many countries are adopting the climate change agenda across the world to achieve sustainable development goals and change from nonrenewable energies to those coming from inexhaustible energy sources, that are more efficient and less polluting. Power-to-hydrogen is an auspicious solution for storing variable renewable energies. LÄS MER

  5. 4. Integrating Waste Heat from Hydrogen Production Into District Heating

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Fawzi Kayali; [2023]
    Nyckelord :Hydrogen; Electrolysis; Waste Heat Recovery; Combined Heat and Power Plant; District Heating; Simulation; Sustainable Heating Systems; Technology and Engineering;

    Sammanfattning : The aim of this research is to explore the feasibility of the integration of waste heat from electrolyzers within a Combined Heat and Power (CHP) plant and district heating (DH) network and suggest a practical setup for integration. With the escalating emphasis on the development of green hydrogen through electrolysis powered by renewable energy, a substantial amount of waste heat is generated, typically left unused. LÄS MER

  7. 5. Jämförelse mellan energilagringstekniker, samt dimensionering av batterier och vätgaslagring i off-grid system med solceller : En mjuk multikriterieanalys, samt skapandet av ett dimensioneringsverktyg som tillämpas på befintliga verksamheter

    Master-uppsats, Linköpings universitet/Energisystem

    Författare :Vendela Stenholm; Sara Sjödin; [2023]
    Nyckelord :;

    Sammanfattning : Elsystemet måste vara i balans mellan den el som produceras och den el som konsumeras, i varje sekund året om, för att undvika effektbrist. Risken för obalans i elsystemet ökar dock, delvis på grund av en ökad andel förnybar och intermittent elproduktion. LÄS MER
