  1. 1. Future-competing battery chemistries for large-scale energy storage

    University essay from KTH/Kemiteknik

    Author : Erik Adolfsson; [2023]
    Keywords : Battery energy storage systems; Nickel-hydrogen battery; Zinc-bromide flow battery; Iron-air battery; Large-scale applications; Batterier för energilagringssystem; Nickel-vätgasbatteri; Zink-brom flödesbatteri; Järn-luftbatteri; Storskaliga användningsområden;

    Abstract : ’Netto-noll utsläpp’ i EU vid 2050 är ett av målen för att påskynda övergången från fossila bränslen till mer förnyelsebara och hållbara alternativ. Detta har däremot introducerat mer turbulens på elnäten. READ MORE

  3. 2. Energy flows and potential energy development strategies in RoRo ports: A study based on the Port of Trelleborg

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Gabriele Gonzales; [2023]
    Keywords : RoRo Ports; Energy Flows; Energy Development; Energy Strategies; Renewable Energy; Ports; Energy Hub; Energy Storage; Hydrogen; Technology and Engineering;

    Abstract : The recent push for decarbonization in the maritime sector presents an opportunity for ports to strengthen their position as energy hubs. This work studies the existing energy flows in the Port of Trelleborg, one of Europe's biggest roll-on, roll-off ports, and proposes some energy-related development strategies. READ MORE

  4. 3. Resonant overvoltages caused by transformer energization and saturation : Two EMT case studies conducted using models of the grid in Stockholm and an off-shore wind farm

    University essay from Uppsala universitet/Elektricitetslära

    Author : Gustav Sundberg; [2021]
    Keywords : Resonant overvoltages; Resonance frequency; Parallel resonance; EMT studies; Transformer saturation; Off-shore wind power; Inrush current; Sympathetic Inrush; Resonanta överspänningar; Resonansfrekvens; Parallellresonans; EMT-studier; Magnetiseringsström; Havsbaserad vindkraft;

    Abstract : This thesis investigates the impact of resonant overvoltages and their origin. Series and parallel resonances are present in any electrical grid. The frequency of which this resonance occurs is called resonance frequency. READ MORE

  5. 4. Centrifugal Turbopumps - Flow Physics and Modelling

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Carl Eriksson; Hampus Henåker; [2021]
    Keywords : Centrifugal Pumps; Rocket Science; Turbopumps; Two-Zone Model; Impeller; Vaneless Diffuser; Vaned Diffuser; Technology and Engineering;

    Abstract : Choices made in the early stages of a design process are crucial. They dictate many of the limitations and freedoms the designer has in later stages of the design. Informed decisions are therefore crucial at this stage. READ MORE

  6. 5. Development of a 2D Optimal Path Simulation for Ship-to-Shore Cranes : Safe Trajectories within Interchangeable Obstalce Environments

    University essay from Linköpings universitet/Fordonssystem

    Author : Rickard Green; [2020]
    Keywords : Optimal Path; Control; Control theory; Obstacle; Safe trajectories; LiU; ISY; Reglerteknik;

    Abstract : The most advanced ports as of writing of this report are at least somewhat autonomous. Whether discussing the transporters between crane and stack (temporary storage) or cranes, the ports are shifting into a completely autonomous system. This ultimate goal presents a challenge in regards to unloading and loading cargo ships in the harbour. READ MORE
