  1. 6. Techno-economic analysis of large-scale production of e-methanol, via CO2- hydrogenation, in Power-to-X

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Jonathan Ahlbäck Ikonen; [2023]
    Nyckelord :Power-to-X; E-methanol; Hydrogen Production; CO2-hydrogenation; Methanol Synthesis; Decarbonisation; Chemical Engineering; Technology and Engineering;

    Sammanfattning : Global levels of carbon emissions are constantly rising causing irreversible damages to ecosystems. The heavy transport sector and the industrial sector are responsible for large amounts of the emissions on a yearly basis. LÄS MER

  3. 7. Techno-economic analysis of a waste-to-energy system using innovative pyrolysis process

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

    Författare :Hannah Sofie Perrens; [2023]
    Nyckelord :Waste management; pyrolysis; heat and power generation; decentralized energy systems; waste-to-energy;

    Sammanfattning : Waste management is of growing concern with increasing amount of municipal waste generation and the industry standards are becoming stricter due to climate goals and sustainable development. Waste-to-energy (WTE) systems in the form of waste incineration have been promoted as a low-carbon energy source, but nevertheless have high greenhouse gas (GHG) emissions. LÄS MER

  4. 8. 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

  5. 9. Seawater Heat Recovery by the Utilisation of Phase Change Heat of Freezing : Technical feasibility study of a system for District Heating in the city of Helsinki

    Master-uppsats, KTH/Kraft- och värmeteknologi

    Författare :Rakesh Ramesh; [2022]
    Nyckelord :District heating; Seawater; Ice slurry; Aspen Plus; Pressure drop; Fjärrvärme; Havsvatten; Isslurry; Aspen Plus; Tryckfall;

    Sammanfattning : With the Paris agreement calling to limit global warming to 2°C below pre-industrial levels, with further efforts to ensure it stays below 1.5°C, the Finnish government passed the Lakihiilen energiakäytön kieltämisestä (416/2019), i.e. LÄS MER

  7. 10. Electrified Reforming of Biogas to Hydrogen for Industrial Furnaces with Negative Carbon Emissions: A Feasibility Study

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Moa Bertling; Agnes Milstig; [2022]
    Nyckelord :;

    Sammanfattning : The steel industry emits large amounts of carbon dioxide, the main emissions are produced inthe process of heating up steel in industrial furnaces of electric arc furnaces (EAF). The purposeof this project was to propose and evaluate a process of reforming biogas to hydrogen to use asfuel for industrial furnaces and result in carbon neutral or carbon negative emissions.
