  1. 1. Egenproduktion av elektricitet via ett bränslecellsfordon på ett mikrobryggeri i Mellansverige : Analys av kostnader och systemverkningsgrad

    Kandidat-uppsats, Högskolan i Gävle/Energisystem och byggnadsteknik

    Författare :Lovisa Dahl; Matilda Hibner; [2023]
    Nyckelord :Electricity generation; brewery; availability of electricity; electrolysis; hydrogen; fuel cell.; Elproduktion; bryggeri; eltillgänglighet; elektrolys; vätgas; bränslecell.;

    Sammanfattning : För att uppnå de globala målen för hållbar utveckling krävs en omställning i dagensenergisystem, där fossila resurser bör ersättas med förnybara energikällor såsom soloch vindkraft. Då dessa energikällor har en intermittent energiproduktion, krävsenergilager för att de ska kunna ta över som huvudsakliga energikällor. LÄS MER

  3. 2. Life Cycle Assessment of Electric Road Systems - Climate impact in comparison with battery electric vehicles, biogas vehicles and fuel cell electric vehicles

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Miljö- och energisystem

    Författare :Ebba Söderström; Emanuel Bengtsson; [2022]
    Nyckelord :Electric road systems; Elonroad; life cycle assessment; rail; feed-in station; pick-up; on-board charger; climate impact; global warming potential; articulated lorry; lower medium car; bus; Technology and Engineering;

    Sammanfattning : One third of Sweden's total annual greenhouse gas emissions originate from the transport sector today and great changes are thus needed in order to reach the net zero emission target by 2045. One of the most important measures discussed is an increased electrification of the transport sector and a solution with potential to contribute to this transition is electric road systems (ERS), where vehicles are charged dynamically.

    Sammanfattning : Fuel Cell Hybrid Electric vehicles are hybrid vehicles that consist of both fuel cells and batteries as energy conversion systems. The Energy Management System plays an important role in the operation of the fuel cell hybrid system, as it helps in reducing the hydrogen consumption of the system. LÄS MER

  7. 5. The Swedish energy system and the role of hydrogen : a modelling study of the energy and transport sector

    Master-uppsats, KTH/Energi och klimatstudier, ECS

    Författare :Adrian Lefvert; [2018]
    Nyckelord :;

    Sammanfattning : In light of the ongoing climate change dilemma, and the consequences that a failure to reduce the greenhouse gas emissions to a stable level will most likely induce, there is an overwhelming consensus among scientists and political leaders that actions are necessary to ensure that adaptation and mitigation options are secured. The European Union, as well as the Swedish government, agrees with the Intergovernmental Panel on Climate Change and the United Nations Conference of Parties that a reduction of the fossil fuel dependency is essential.
