  1. 21. Optimization of battery pack assembly of second life cells to reduce costs

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

    Författare :Akash Prasad Chowdry; [2022]
    Nyckelord :Batteries; second life cells; active cell balancing; lossless cell balancing; off-grid solar; solar home systems; Batterier; second life cells; aktiv cellbalansering; förlustfri cellbalansering; solceller utanför nätet; solcellssystem för hemmabruk.;

    Sammanfattning : Batteries account for 50% of the overall cost of solar home systems (SHS). The battery packs degrade over time and when they reach 70% state of health (SOH), the whole SHS is discarded. In the predominantly rural off-grid context, battery replacements are expensive and impractical. The customers are often dozens of km away from any sales point. LÄS MER

  3. 22. Waste Heat Driven Membrane Distillation Integrated with Stirling Engine

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

    Författare :Jonatan Talåsen; Niklas Bergman Larsson; [2022]
    Nyckelord :Carnot batteries; Stirling engine; Azelio AB; Scarab Development; Thermal Energy Storage TES; Membrane Distillation; Air Gap Membrane Distillation; Waste heat integration; Water scarcity; Power on demand; Sustainability; Carnotbatterier; Stirlingmotor; Azelio AB; Scarab Development; Termisk Energi lagring TES; Membrandestillation; Air Gap Membrane Distillation; Spillvärmesintegration; Vattenbrist; Ström på begäran; Hållbarhet;

    Sammanfattning : In this thesis, the potential to purify water utilizing waste heat from a unit which stores thermal energy and converts it to electricity is studied. The unit, called TES.POD, is developed by Azelio AB and is in this thesis used as a heat source to drive an air gap membrane distillation (AGMD) unit developed by Scarab Development AB. LÄS MER

  4. 23. Analysis of Off-grid Energy Systems for Small Villages at Three Different Locations

    Master-uppsats, Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet

    Författare :HARDY THOMAS; Dimal Varkey Alex; [2022]
    Nyckelord :Off-grid system; Renewable Sources; Photovoltaic system; Wind Mill; Nairobi; Simris.;

    Sammanfattning : The development of new communities to facilitate the growing population isan ongoing trend, with locations outside the city limits so as to have morearea and less pollution. The main need in isolated communities is to secureenergy demand, which is normally done with power supply from the maingrid, which will require new transmission lines and transformer installation,among other things.

  5. 24. Can batteries be useful in industrialelectricity systems?

    Master-uppsats, Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet

    Författare :Jamal Abo Warda; [2022]
    Nyckelord :Batteries; photovoltaic systems; off-grid battery work; maximum load; working time transfer.;

    Sammanfattning : This study provides an analysis of the benefits of adding solar PV and batteries to industries, both examing the grid-connected and off-grid cases.The electricity demand of 28 companies in Falkenberg, Sweden, whose industries require high voltages for electricity, were studied.

  7. 25. Energy efficiency measures in a typical Swedish single-family building from the 1960s

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Byggteknik och byggd miljö

    Författare :Emanuel Larsson; Raffaello Ljungqvist Baldesi; [2022]
    Nyckelord :energy system; building; energy efficiency measures; storage; solar panels; electricity demand; heating demand; insulation;

    Sammanfattning : Many buildings built in the 1960s are inefficient when it comes to their energy use. A lot of them are also in need of renovating. Therefore, this project is aiming to investigate five different scenarios where the decrease in electricity demand is in focus. LÄS MER
