  1. 1. Decentralizing electricity generation in Cuba : Implementation of a microgrid in the sugar mil lCarlos Baliño

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

    Författare :Aylin Berber; Cornelia Eriksson; [2023]
    Nyckelord :Microgrid; renewable energy; bagasse; self-sufficiency; Microgrid; förnybar energi; bagass; självförsörjande;

    Sammanfattning : Cuba has a long history of different dependencies and is a country facing many energy challenges, and therefore seeks to diversify its energy sources and reduce its reliance on fossil fuels. The purpose of this degree project is therefore to conceptualize a microgrid based on renewable energy sources for local energy sustainability at the lowest cost possible. LÄS MER

  3. 2. Heterogeneous catalytic reactions studied with transient gas supply and event-averaged ambient pressure x-ray photoelectron spectroscopy

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/NanoLund: Centre for Nanoscience

    Författare :Qianhui Liu; [2022]
    Nyckelord :Ambient pressure x-ray photoelectron spectroscopy; Event-averaging; Pd 100 surface structure oscillation; Physics and Astronomy;

    Sammanfattning : CO oxidation over Pd(100) is studied with ambient pressure x-ray photoelectron spectroscopy (APXPS). Cyclic gas composition pulsing of the CO:O2 ratio, combined with a new method using software based event-averaging by image recognition over many pulses, is used to improve the signal-to-noise ratio substantially.

  4. 3. The influence of geopolitical conflicts on energy dependency : A case study on the effect of the Ukrainian conflicts on gas dependency involving Russia and the European Union

    Master-uppsats, Linköpings universitet/Statsvetenskap

    Författare :Jesse Ottens; [2022]
    Nyckelord :Interdependence geopolitics asymmetry Russia-EU relations natural gas sanctions trade.;

    Sammanfattning : In recent decades the EU has become more dependent on Russia for gas. At the same time, there were several geopolitical conflicts in Ukraine that disrupted gas relations and thus put dependence under pressure. This research aimed to analyse the relationship between geopolitical conflicts and dependency. LÄS MER

  5. 4. Fundamental combustion properties of alternative fuels for energy transition

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

    Författare :Yijing Mao; [2020]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Validation and improvement of chemical kinetic modelling require accurate experimental data. The over goal of the present work is to obtain accurate data by using techniques that have been previously implemented in common flames, e.g. LÄS MER

  7. 5. Development of a modern catalytic system for the production of C3+ aliphatic alcohols by the Fischer-Tropsch method

    Master-uppsats, KTH/Energiteknik

    Författare :Aravind Ganesan; [2019]
    Nyckelord :syngas; Cobalt; Fischer-Tropsch; alcohols; hydrocarbons; syngas; kobolt; Fischer-Tropsch; alkoholer; kolväten;

    Sammanfattning : This thesis deals with converting a mixture of H2 and CO, also referred to as syngas or producer gas, to higher or mixed alcohols and other fuels through a process called Fischer Tropsch Synthesis (FTS). It is a beneficial pathway that minimizes the dependence on oil and similar fossil fuels which contribute to rapid climate change by releasing harmful greenhouse gases. LÄS MER
