    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för kemi - Ångström

    Författare :Jennifer Andersson; [2022]
    Nyckelord :Relining; Epoxy; District heating; Corrosion; BPA; Glass-transition temperature; Relining; Rörinfodring; Fjärrvärmesystem; Livstidsförlängning; Korrosion; Rost; Epoxi; BPA; Tvärbundna polymerer; Sorption; Diffusion; Glasomvandlingstemperatur; Joniska transportvägar; Friktionsfaktor;

    Sammanfattning : Degradation of steel pipes in district heating systems is often a result of corrosion processes. To maintain the power in the systems the pipes gets replaced when they have been worn-out, resulting in high cost and long service time due to excavation. LÄS MER

  3. 12. Techno-Economic Assessment of High-Temperature H2O/CO2 : Co-Electrolysis in Solid Oxide Electrolysers for Syngas Production

    Master-uppsats, KTH/Kemiteknik

    Författare :Shivani Ramprasad Jambur; [2022]
    Nyckelord :Co-electrolysis; Power-to-X; Process modeling; Green Syngas; Solid-Oxide Electrolyser;

    Sammanfattning : High-temperature Co-electrolysis of H2O and CO2 in a solid-oxide electrolyser (Co-SOE) for syngas production is a high-efficiency renewable electricity conversion and storage method part of the Power-to-X technologies. Syngas, a mixture of H2, CO and CO2, is a critical building block to make several chemical and synthesis fuels. LÄS MER

    Sammanfattning : The ocean has tremendous potential in terms of energy generation, and wave energy is especially promising. However, wave energy technology is still non-commercial. LÄS MER

  7. 15. Need for Speed(y) Conversion to a Low-Emission Vehicle Fleet : The Incidence of the Swedish Feebate Tax in the Presence of the Impending EU CO2 Emission Standards

    Master-uppsats, Uppsala universitet/Nationalekonomiska institutionen

    Författare :Michaela Dagher; [2022]
    Nyckelord :feebate tax; tax incidence; BonusMalus; vehicle fleet;

    Sammanfattning : In 2014, the European Union and its members agreed to reduce carbon dioxide emissions by 40 percent before 2030. The Bonus-Malus, a feebate tax scheme, was introduced in Sweden in 2018 in the hopes that it would result in lower carbon dioxide emission from Sweden’s transport sector. LÄS MER
