  1. 6. Simulation, Design, and Implementation of a Narrow Linewidth Ytterbium Fiber MOPA System at 1087 nm

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Berkay Efilti; [2023]
    Nyckelord :Applied Physics; Laser Physics; Fiber Lasers; Fiber Amplifiers;

    Sammanfattning : This thesis focuses on simulating, designing, and characterizing a narrow-linewidth continuous-wave (CW) Ytterbium (Yb) master oscillator fiber amplifier (MOFA) system. The primary goal was to achieve a watt-level output at 1087 nm with a narrow 1 GHz linewidth, making the MOFA well-suited for serving as a pump source in Terahertz (THz) generation experiments.

  3. 7. State of Health estimation of battery systems

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Carl Spångberg; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : This study focuses on estimating the state of health (SoH) of a lithium iron phosphate (LFP) battery system, which is crucial for assessing the value and lifespan of new or used batteries in energy storage, grid support, and electric vehicle applications. A proposed method for determining SoH based on comparing useful and nominal useful capacities in Ah and Wh, as well as total and nominal capacity, has been presented. LÄS MER

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

    Författare :Roni Ali; [2023]
    Nyckelord :elektriska transporter; MCS; Mega Watt Charging; elnät; transporter;

    Sammanfattning : Sweden has ambitious climate goals, such as the overarching goal, the 2045 goal. The goal is for Sweden to have zero net emissions of greenhouse gases by 2045 at the latest. In order to achieve the overall climate goal and the interim targets, electrification of society is an important component. LÄS MER

    Nyckelord :European Green Deal; Automobile Industry; Sustainability; Innovation; Electrification; research and development; policy change;

    Sammanfattning : The attitude towards sustainability has vastly changed in the last few years.The European Green Deal(EGD) is a European law package that addresses the climate crisis and aims to transform businesseswithin the European Union towards more sustainable models. LÄS MER

  7. 10. Modelling and Techno-economic Analysis of a Hybrid CSP/PV System using Solid Oxide Electrolyser for Hydrogen Production

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

    Författare :Chuanyin Tang; [2023]
    Nyckelord :Power to Hydrogen; Solid Oxide Electrolyser; CSP; PV; LCOE; LCOH.;

    Sammanfattning : This project proposes a solar-driven hybrid system for electricity generation and hydrogen production, which includes concentrated solar power (CSP), photovoltaic (PV), solid oxide electrolyser (SOEC). Electricity from the CSP and PV provides a continuous 24/7 supply to meet demand-side power consumption.
