  1. 1. What is vulnerability to climate change and who are the particularly vulnerable?

    Master-uppsats, Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)

    Författare :Emilie Greve Pobiega; [2024]
    Nyckelord :Earth and Environmental Sciences;

    Sammanfattning : The effects of climate change are resulting in harmful impacts — known as loss and damage — hitting the most vulnerable countries the hardest. At COP27 in Sharm el- Sheikh, a new “loss and damage fund” was agreed upon, creating history within the international climate change policy arena. 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. Optimization of an energy system in rural Thailand

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

    Författare :Axel Lund; Mattias Malmberg; [2023]
    Nyckelord :Rural energy; Thailand; Microgrid; Biomass; Solar PV; Sustainable development goals; Minor field study; stand-alone; HOMER pro; Landsbyggdens energi; Thailand; Microgrid; Biomassa; Solceller; Hållbara utvecklingsmål; Minor field study; fristående energi system; HOMER pro;

    Sammanfattning : By 2020, Thailand ensured 100% electricity access to its 72 million inhabitants. This was partly done by promoting off-grid energy systems in rural areas instead of using costly grid extensions. LÄS MER

  5. 4. Arbetsterapeutiska interventioner i skolan för barn med ADHD- en scoping review

    Magister-uppsats, Jönköping University

    Författare :Sandy Racho El-Homsi; [2023]
    Nyckelord :Arbetsterapi; attention deficit hyperactivity disorder ADHD ; barn; interventioner; skola;

    Sammanfattning : Introduktion: Barn med ADHD upplever svårigheter i miljön de befinner sig i, främst skolan. Skolupplevelsen är utmanande och prestationen är sämre än förväntat. Oförmåga till stillasittande och upprätthålla koncentrationsförmågan medför svårigheter att prestera akademiskt. LÄS MER

  7. 5. Modeling of an Electrolysis System for Techno-Economic Optimization of Hydrogen Production

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

    Författare :Jürgen Köstlbacher; [2023]
    Nyckelord :Hydrogen; Hydrogen Production; Green Hydrogen; LCOH; Electrolysis; PEM; AEL; MILP; Optimization; Techno-Economic Analysis; Cost Optimization; PPA; vätgas; vätgasproduktion; grön vätgas; LCOH; elektrolys; PEM; AEL; MILP; optimering; tekniskekonomisk analys; kostnadsoptimering; PPA;

    Sammanfattning : In face of climate change, Europe and other global actors are in the process of transitioning to carbon-neutral economies, aiming to phase out of fossil fuels and power industries with renewable energies. Hydrogen is going to play a crucial role in the transition, replacing fossil fuels in hard-to-decarbonize industries and acting as energy carrier and energy storage for renewable electricity. LÄS MER
