  1. 1. Numerical modeling of airflow on the cathode-side of a bipolar flow plate : How the formed geometry affects the pressure drop and flow distribution in a hydrogen fuel cell

    Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Olivia Johansson; [2023]
    Nyckelord :Performance; Cross-sectional geometry; Computational fluid dynamics;

    Sammanfattning : Climate change and rising temperatures is a well-known problem. To tackle global warming a transition from fossil fuels to renewable and reliable energy sources is necessary. Hydrogen, in fuel cells, is proposed to replace diesel and gasoline in the transport sector. LÄS MER

  3. 2. Research on the Hydrothermal Conversion of Xylose Catalysed by CO2-H2O into Furfural

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

    Författare :Robert Liao; [2023]
    Nyckelord :;

    Sammanfattning : Agricultural waste treatment and carbon dioxide emissions from fossil fuel combustion have been critical challenges for sustainable development. This work is part of a study on converting straw into biofuels, which involves using xylose as the material, carbon dioxide (CO2) as the catalyst, and water (H2O) and Gamma-Valerolactone (GVL) as the solvent to produce furfural through hydrothermal conversion.

    Sammanfattning : The automotive industry is a highly competitive market where companies from all over the world are active. Customers and laws place high demands on this ever-changing industry. LÄS MER

  5. 4. Chemical Kinetic Modeling of the Combustion of NH3/H2 and NH3/syngas Fuel Mixtures Using a Large Amount of Experimental Data

    Master-uppsats, Lunds universitet/Kemiska institutionen

    Författare :Andras Szanthoffer; [2022]
    Nyckelord :Ammonia combustion; Detailed chemical kinetic mechanisms; Quantitative mechanism comparison; Local sensitivity analysis; Chemical Physics; Chemistry;

    Sammanfattning : Nowadays, due to the global climate change, it is extremely important to find alternative fuels to reduce the utilization of fossil fuels and the emission of air pollutants such as carbon dioxide (CO2), hydrocarbon pollutants, and soot. Ammonia (NH3) is a promising carbon free fuel candidate that can store and transport renewable hydrogen (H2) energy. LÄS MER

  7. 5. SAVINGS OF MATERIAL RESOURCES AND CARBON EMISSIONS WHEN CONVERTING FOSSIL FUEL CAR TO ELECTRIC : A CASE STUDY FOR SWEDEN

    Master-uppsats, KTH/Integrated Transport Research Lab, ITRL; KTH/Elkraftteknik

    Författare :Daniel Hiller; [2022]
    Nyckelord :LCA; carbon emissions; material resources; fossil fuel vehicles; battery electric vehicles; carculator; Sweden; LCA; Kohlenstoffemissionen; Materialressourcen; Fahrzeuge mit fossilen Brennstoffen; batterieelektrische Fahrzeuge; carculator; Schweden;

    Sammanfattning : Transportation in Sweden currently accounts for one-third of domestic GHG emissions. Thereof more than 90 % are allocated to road traffic with passenger cars being the largest contributor. Hence, the Swedish government adopted stringent climate policies to cut transport emissionsby 70 % (compared to 2010) latest until 2030. LÄS MER
