  1. 1. Electrification of Last-Mile Transport : A Study of Charging Infrastructure and Collaborative Business Model

    Master-uppsats, KTH/Energiteknik

    Författare :Elin Johansson; Marcus Rostmark; [2022]
    Nyckelord :Electrification; electric vehicles; last-mile; charging infrastructure; risk analysis; collaborative business models; Elektrifiering; elfordon; sista milen; laddinfrastruktur; riskanalys; kollaborativ affärsmodell;

    Sammanfattning : Electrification of the transport sector is an important step in reducing the global greenhouse gas (GHG) emissions. Compared to traditional internal combustion engine vehicles (ICEVs), electric vehicles (EVs) produce no tail-pipe emissions and could be coupled with responsible energy production from renewable energy sources to reduce coupled emissions of their operation.

  2. 2. The Optimal Bidding Strategy of a Wind-Biogas-Hydrogen Hybrid System

    Magister-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Xudong Liu; [2022]
    Nyckelord :bidding strategy; wind; biogas; hydrogen; hybrid system; two-price settlement;

    Sammanfattning : The growing penetration of variable renewable energy has brought all-round challenges to the current power system, no matter for the grid infrastructure, market design or the power producers. The positive and negative externalities caused by the market participators are to be finer priced and a significant amount of flexibility is to be added to the system, in order to counter these problems and facilitate energy transition.

  3. 3. X-Ray Fluorescence of Metal Halide Perovskites

    Kandidat-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Författare :Samuel Narciso Silva; [2022]
    Nyckelord :Perovskite; X-ray; Fluorescence; Python; PyMCA; Synchrotron radiation; Physics and Astronomy;

    Sammanfattning : This thesis has the aim to provide a framework for analyzing X-ray fluorescence (XRF) data obtained from German Electron-Synchrotron Group (DESY). The theoretical analysis shows that XRF competes with Auger emission, and works mainly for elements with high atomic number. Here, incident X-rays of 13. LÄS MER

  4. 4. Energibehovet i Skåne - En analys av klimat- och energistrategin med LEAP

    Magister-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Tobias Frolov; [2022]
    Nyckelord :Energy demand; Carbon dioxide emissions; Climate analysis; Modelling; Earth and Environmental Sciences;

    Sammanfattning : Climate change is one of the great challenges of our time and requires adaptation on many levels of society, including a transition to renewable energy sources. There is a goal to achieve a fossil-free and climate-neutral Scania by 2030, which puts pressure on the energy system which must also meet rising energy demands. LÄS MER

  5. 5. Optimization of Infrastructure Investment for Decarbonization of Public Buses Through Electricity and Hydrogen : The Case Study of Umeå

    Master-uppsats, KTH/Energiteknik
