  1. 21. 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

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Olivia Johansson; [2023]
    Keywords : Performance; Cross-sectional geometry; Computational fluid dynamics;

    Abstract : 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. READ MORE

  3. 22. Offshore Hydrogen Production and Storage for Wave Energy Application : A Techno-Economic Assessment for a Japanese Context

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Keywords : Hydrogen; Green Hydrogen; Hydrogen Storage; Hydrogen Production; Wave Energy; Offshore Hydrogen; Levelized Cost of Hydrogen; Vätgas; Grön vätgas; Vätgaslager; Vätgasproduktion; Vågkraft; Havsbaserad vätgas iv;

    Abstract : There is a well-established market for hydrogen, mainly for refining purposes, producing chemicals, and producing fertilizers. Today, almost all hydrogen is sourced from fossil fuels, with less than 1% of hydrogen sourced from renewable sources. READ MORE

  4. 23. Scaling and optimisation of Hydrogengeneration in correlation with Wind parkenergy production : Involving the development of a tool for case simulation

    University essay from Umeå universitet/Institutionen för fysik

    Author : Ida Kindlund; [2023]
    Keywords : Reversible Hydogen generation; Simlation; Planning and optimisation;

    Abstract : In the global transition from fossil fuels to renewable energy sources, hydrogen is predicted to play a large role. It is particularly interesting in areas where batteries and electrification are not viable options, as well as stabilisation of power deliverance from volatile, green energy production. READ MORE

  5. 24. Future-competing battery chemistries for large-scale energy storage

    University essay from KTH/Kemiteknik
