  1. 1. Utredning om lönsamhet av solceller för privata hushåll

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för byggteknik (BY)

    Författare :Abdullah Al-Jadirji; [2024]
    Nyckelord :electricity consumption; electricity production; payback period; investment support; electricity bill; elförbrukning; elproduktion; återbetalningstid; investeringsstöd; elräkning;

    Sammanfattning : År 2015 fastställde FN 17 globala mål för hållbar utveckling. Delmål 7.2, en del av det sjunde målet om hållbar energi för alla, anger att den globala andelen förnybar energi behöver öka för att minska effekterna av fossila bränslen. LÄS MER

  3. 2. Exploring potential E-fuel production pathways for maritime and aviation sectors in France : a techno-economic and environmental assessment

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

    Författare :Mathieu Minaud; [2024]
    Nyckelord :;

    Sammanfattning : The aviation and maritime industries pose significant challenges for decarbonization, having increased activity in the past decade. One promising solution to limit emissions in these sectors is Electrofuels (E-fuel), derived from water electrolysis hydrogen and captured CO2 or nitrogen. LÄS MER

  4. 3. Life Cycle Assessment : a comparison of fossil energy use and climate impact on small scale manufacturing and large scale conventional manufacturing of textile toys

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Energy and Technology

    Författare :Malin Henriksen; [2024]
    Nyckelord :textile toy; LCA; energy use; sustainable production; China; Sri Lanka; cotton production; fossil fuel use; GWP100;

    Sammanfattning : This study conducts a Life Cycle Assessment to compare the environmental impacts, specifically climate impact and fossil fuel use, of textile toys produced in China and Sri Lanka. Through evaluating large-scale industrial production in China against small-scale, handcrafted production in Sri Lanka, it identifies the considerable environmental footprint of cotton production in both scenarios.

  5. 4. FPGA Based Control of Multiple Electric Machines for Marine Propulsion Systems

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Simon Weideskog; [2024]
    Nyckelord :FPGA; Field Oriented Control; BLDC; SVPWM; SMO; Electric Drives; Electric Machines; Sliding Mode Observer; Marine Propulsion; Multiple Machines; Boat Motor; Fältorienterad styrning; marin framdrivning; elektriska drivsystem; elmaskiner; flertal maskiner; båtmotor;

    Sammanfattning : This master thesis addresses the control of electric propulsion motors in a marine context. The focus lies mainly on the implementation of field oriented control (FOC) in a field programmable gate array (FPGA). The hypothesis is that FPGAs provide performance advantages over microcontroller-based control solutions by enabling parallel processing. LÄS MER

  7. 5. 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. LÄS MER
