  1. 1. Metals for energy storage : For hydrogen and power generation

    Master-uppsats, Linköpings universitet/Konstruktionsmaterial

    Författare :Oscar Torsteinsrud; Mattias Reijm; [2023]
    Nyckelord :Metals; Energy Storage; Round Trip Efficiency; Aluminum; Boron; Magnesium; Silicon; Zinc;

    Sammanfattning : With an increase in energy demand and a transition from conventional fossil-driven energy generation, the world is facing a major challenge. This transition implies more intermittent energy sources whose reliance varies widely with time. To deal with this challenge, energy storage is one part of the solution. LÄS MER

  3. 2. Fault current injection from Inverter Based Generation in the distribution grid : A case study of distribution grid on the Swedish island of Gotland

    Master-uppsats, Uppsala universitet/Institutionen för elektroteknik

    Författare :Farsad Mansori; [2022]
    Nyckelord :Distribution generator; Inverter-Based Distributed Generation; Inverter Based Generation; DFIG; PSCAD; Distribution grid; Overcurrent protection;

    Sammanfattning : This work proposes recommendations for new guidelines for fault current injection on a distribution grid. These guidelines will help improve the transition towards renewable electrical energy generation. LÄS MER

  4. 3. Coulomb drag in parallel nanowires

    Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Författare :David Dai; [2020]
    Nyckelord :Coulomb drag; nanowire; Physics and Astronomy;

    Sammanfattning : In this project the transport phenomenon Coulomb drag is studied in a 1D system comprised of two nanowires in parallel. Specifically, a driving current across the active wire generated a drag current in the passive wire, and we studied how Coulomb drag influenced both the driving and drag currents. LÄS MER

  5. 4. Ångbesparingsåtgärder för ångsotning i en sodapanna : Effekter på elgenerering och driftparametrar på grund av minskad ångsotningsmängd i en sodapanna

    M1-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Jonathan Norrman; [2018]
    Nyckelord :Sodapanna; ångsotning; beläggningar;

    Sammanfattning : I detta arbete har effekterna av en reducerad sotångsmängd i sodapannan för BillerudKorsnäs bruk i Skärblacka undersökts. Det har undersökts om HISS-sotning vilket minskar mängden sotånga kan driftsättas och vad detta kan få för konsekvenser. LÄS MER

  7. 5. Techno-economic analysis of the Local System Operator concept in a multi-dwelling unit in Sweden : A parametric sizing and optimization of a PV-battery system with EVs equipped with vehicle-to-home application

    Master-uppsats, KTH/Tillämpad termodynamik och kylteknik

    Författare :Joel Mars Bodell; Camilo Tapia Chiriboga; [2018]
    Nyckelord :;

    Sammanfattning : The climate change of the environment raises concerns about the increasing greenhouse gas (GHG) emissions where the energy sector is a large contributor to the emission problems. As the electricity demand rises, due to increased population, urbanisation, and improved lifestyle, expanding the renewable generation can solve the problem of covering the increased electricity demand while decreasing the GHG emissions.
