  1. 16. Key Performance Indicators for the monitoring of large-scale battery storage systems

    Master-uppsats, KTH/Energiteknik

    Författare :Emeric Brun; [2019]
    Nyckelord :;

    Sammanfattning : In the context of the fight against climate change, the electricity sector is experiencing a complete renewal. Power grids are undergoing a transformation from centralized and unidirectional systems to multilevel and more integrated networks with, among others, the insertion of intermittent Renewable Energy Sources (RES) on the production side and with the emergence of new consumer behaviors on the demand side.

    Sammanfattning : Climate change is one of humanities greatest challenges; the greenhouse gases in the atmosphere are still increasing. There is not one solution that will fix this problem several different products, raw material and technologies are required to take the steps towards a renewable society. LÄS MER

  4. 18. Modelling of Biomass Pyrolysis with Ex-situ Catalytic Upgrading for Bio-crude Production

    Master-uppsats, KTH/Materialvetenskap

    Författare :Febryana Nugrahany; [2018]
    Nyckelord :ex-situ catalytic upgrading; slow pyrolysis; screw reactor; fixed bed catalytic reactor; process design;

    Sammanfattning : This study presents a techno-economic assessment of slow pyrolysis of pine sawdust continued by ex-situ catalytic upgrading. The overall process consists of six sections: feed drying, pyrolysis, vapor filtration, ex-situ catalytic upgrading, vapor quenching, and combustion of permanent gas. LÄS MER

  5. 19. Concentrated Solar Thermal Plant for Future Fuels Production : Process Modeling and Techno-economic Analysis of Syngasoline, Syndiesel, Ethanol and Methanol Production Using Thermochemical Cycle based on Metal Oxide

    Master-uppsats, KTH/Kraft- och värmeteknologi

    Författare :Philipe Gunawan Gan; [2018]
    Nyckelord :;

    Sammanfattning : Concentrated Solar Thermal technology (CST) is a very promising renewable energy technology and has a broad range of use. Conventionally, CST systems are mostly used for power generation according to the Rankine cycle and thus often referred to as Concentrated Solar Power (CSP). LÄS MER

  7. 20. Kombinerad uppvärmning av fastighet och kylning av isplan : Fallstudie med termisk analys av Innertavle bygdegård

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Mattias Strandberg; [2018]
    Nyckelord :Geotermisk energi; Bergvärme; Markvärme; Energisystem; Värmepump; Isplan; Uppvärmning; Kylning; Borrhålslängd; Markvärmesimulering;

    Sammanfattning : Med en ökande energiåtgång i världen krävs en omställning av energisystemet, med energieffektiva lösningar så att all energi används till sin fulla potential. Urbaniseringen har inneburit ett fokus på städer med stora system för samproduktion, menäven i mindre samhällen är hållbara energilösningar en viktig del i samhällsplaneringen. LÄS MER
