  1. 1. Improving energy security for individual households during outages : A simulation study for households in Sweden

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Fasta tillståndets fysik

    Författare :Amelie Bennich; [2019]
    Nyckelord :Off-grid; Energy security; Solar power; Energy storage; Outage;

    Sammanfattning : In this study, it was investigated how individual households could manage security of supply during an outage by installing a local energy system that could operate independently from the electricity grid. By installing local renewable off-grid energy systems, households could guarantee an uninterrupted supply of energy even during an outage on the electricity grid, while also increasing their energy autonomy during normal circumstances.

  2. 2. Resilience-enhancement through Renewable Energy Microgrid Systems in rural El Salvador

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Fasta tillståndets fysik; Uppsala universitet/Fasta tillståndets fysik

    Författare :Mathias Alarcón; Robin Landau; [2019]
    Nyckelord :Resilience; El Salvador; Central America; Renewable Energy; Microgrid; Optimization; HOMER; PV;

    Sammanfattning : This Master thesis investigates how Renewable Energy Microgrid Systems (REMS) can enhance resilience for a rural grid-connected community in El Salvador. The study examines the optimally resilient design of a grid-connected PV-Wind-Battery hybrid energy system. LÄS MER

  3. 3. GIS-Based approach to estimate the energy requirements of the post-harvest activities in Souss-Massa basin in Morocco

    Master-uppsats, KTH/Energiteknik; KTH/Energiteknik

    Författare :Francesco Agostini Fantini; Javier Izaguirre Carbonell; [2019]
    Nyckelord :;

    Sammanfattning : Over the last decades the Moroccan agriculture has passed through a complete transformation: due to the low workforce cost and its favourable climate, the sector has attracted the attentions of national and foreign investment and thus has expanded rapidly. Among the different productions, tomatoes proved to be one of the most profitable, generating 4. LÄS MER

  4. 4. Iron-Based Dye-Sensitized Solar Cells - From Theory to Working Solar Cell

    Master-uppsats, Lunds universitet/Centrum för analys och syntes

    Författare :Linnea Lindh; [2019]
    Nyckelord :Dye-sensitized solar cells; Grätzel cells; solar cells of the future; solar cells of tomorrow; spectroscopy; time-resolved spectroscopy; materials chemistry; materialkemi; Chemistry;

    Sammanfattning : In the hunt for fossile-free energy-harvesting techniques, solar cells constitute one of the most promising techniques. Today, silicon-based solar cells are the dominant technique on the market but even the Silicon solar cell has limitations which means that there is a motivation for developing new solutions. LÄS MER

  5. 5. HYDROGEN-FIRED GAS TURBINE FOR POWER GENERATION WITH EXHAUST GAS RECIRCULATION : Emission and economic evaluation of pure hydrogen compare to natural gas

    Master-uppsats, Mälardalens högskola/Framtidens energi; Mälardalens högskola/Framtidens energi

    Författare :Nemir Gibrael; Hamse Hassan; [2019]
    Nyckelord :harmful emission; natural gas; fuel reforming process; hydrogen fired gas turbine; exhaust gas recirculation; techno-economic analysis;

    Sammanfattning : The member states of European Union aim to promote the reduction of harmful emissions. Emissions from combustion processes cause effects on human health and pose environmental issues, for example by increasing greenhouse effect. LÄS MER
