  1. 1. Comparative Analysis of On-site vs Off-site green-Hydrogen Value Chain Scenarios to cover projected Aviation demand : A case for Toulouse Blagnac Airport in France

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

    Författare :Stathis Alexandrou; [2023]
    Nyckelord :Hydrogen Production; Value Chain Analysis; Levelized Cost of Hydrogen Production LCOH ; Hydrogen for Aviation; France; Toulouse Airport; Analys av vätgasens värdekedja; kostnader för vätgasens försörjningskedja; LCOH; flytande vätgas; vätgas för luftfarten; Frankrike; Toulouse Airport; ;

    Sammanfattning : Amidst the efforts to mitigate the energy-related carbon emissions of human activities and pursuing a net-zero future by 2050, the aviation sector, as part of a wider group of hard-to-decarbonize sectors is responsible for 12% of all the transportation emissions globally. Green Hydrogen as a zero-emissions alternative fuel from water and renewable energy serves as a prime candidate to replace conventional aviation fuels and lead the way towards carbon-free flights.

  3. 2. Investigation of fuel and water injection in gas turbine combustion : Evaluate the methodologies available in Star CCM+ for modeling of water injection in simplified combustor using liquid and gas fuels

    Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Sanger Shinwari; [2023]
    Nyckelord :Diesel and Methane fuel combustion; FGM combustion model; Lagrangian multiphase modelling; Inert Stream; Water injection; STAR CCM ;

    Sammanfattning : The negative impact of gas turbine emissions on the environment and human health is a growing concern. Recent studies suggest injecting water into the combustion process effectively reduces emissions and increases power output. However, this approach presents new challenges that need to be thoroughly investigated. LÄS MER

  4. 3. TECHNO-ECONOMIC ANALYSIS OF THE HYDROGEN SUPPLY CHAIN : A CASE STUDY OF THE SWEDISH INDUSTRY

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

    Författare :Jan Lukas Dautel; [2023]

    Sammanfattning : The European Energy system is currently transitioning towards a reduced use of fossil fuels and increasing use of renewable energy. Hydrogen as energy carrier for renewable electricity has a potential to play a significant role in this transition. LÄS MER

  5. 4. Design of a State-Of-The-Art Test Facility for Rocket Engines

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Akash Raja Meghavath; [2022]
    Nyckelord :Rocket architectures; oxidizer feed system; layout plan; safety precautions safety standards; test bed stand; static tests;

    Sammanfattning : The development of innovative propulsion systems requires testing in suitable facilities that reveal the efficacy of design models and allow for design refinement. The qualification process starts from ground tests and ends in vacuum chambers. LÄS MER

  7. 5. Ethylene to Liquid Hydrocarbons by Heterogeneously Catalyzed Oligomerization on ZSM-5

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Fysikalisk kemi

    Författare :Gustav Halldén; [2022]
    Nyckelord :ethylene; ethane; oligomerization; catalyst; heterogeneous catalysis ZSM-5; zeolite;

    Sammanfattning : The aim is to produce aliphatic liquid hydrocarbons using heterogeneous ethylene oligomerization. Thiscould potentially produce renewable synthetic fuels. Heterogeneous catalysis has some advantages overhomogeneous catalysis regarding some sustainability aspects. LÄS MER
