  1. 1. Techno-economic and environmental analysis of alternative pathways for urea fertilizer production.

    Master-uppsats, Linköpings universitet/Industriell miljöteknik

    Författare :Wilson Rodriguez; [2023]
    Nyckelord :Urea fertilizer; ammonia; natural gas; biogas; GWP; PE; hydrogen; nitrogen; technologies.;

    Sammanfattning : The increasing global population has placed significant pressure on meeting food demands, leading to the widespread use of fertilizers to enhance crop yields. Urea, being the most used fertilizer globally, has contributed to improved agricultural productivity. LÄS MER

  3. 2. Evaluating electrolyser setups for hydrogen production from offshore wind power : A case study in the Baltic Sea

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

    Författare :Kenzo Franzén; [2023]
    Nyckelord :electrolysis; energy systems modelling; green hydrogen; offshore wind power; power-to-x; electrólisis; energía eólica marina; hidrógeno verde; modelado de sistemas de energía; power-to-x;

    Sammanfattning : As part of the transition towards a fully sustainable energy system, green hydrogen shows great potential to decarbonise several hard-to-abate sectors. To provide the fossil-free electricity required for electrolysis, offshore wind power has emerged as a suggested option. LÄS MER

  4. 3. Characterisation of Ionic Liquid doped Polybenzimidazole Membranes for Application in High-Temperature Proton Exchange Membrane Fuel Cells

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Adam Jacobsson Trönndal; [2023]
    Nyckelord :Fuel cells; Phosphoric acid; Polybenzimidazole; PA-PBI; Ionic liquid; IL; High temperature proton exchange membrane fuel cell; HT-PEMFC; Electrochemical impedance spectroscopy; EIS; IL-PBI; Chemical engineering; Technology and Engineering;

    Sammanfattning : In this study four membranes were tested and evaluated against each other for use in high-temperature proton exchange membrane fuel cell (HT-PEMFC) applications. A phosphoric acid (PA) doped polybenzimidazole (PBI) membrane, was used as a reference as the current state-of-the-art. LÄS MER

  7. 5. Towards low carbon buildings: A case study in Sweden

    Master-uppsats, Lunds universitet/Avdelningen för Energi och byggnadsdesign; Lunds universitet/Institutionen för arkitektur och byggd miljö

    Författare :Huynh Tuan Tran; Victor-Antoine Delorme; [2023]
    Nyckelord :Life cycle assessment; Environmental impact of building materials; Carbon neutrality; Biobased material; Biochar; Cross Laminated Timber; Biogenic carbon; Earth and Environmental Sciences; Technology and Engineering;

    Sammanfattning : This study comprehensively evaluated the global warming potential of an office building in a newly built Scandinavian neighbourhood seeking to reach sustainability. The primary objective of the research was to support the city authorities of Helsingborg by providing valuable insights into actual carbon emissions at the building level and proposing measures to minimize these emissions to achieve climate neutrality by 2030.
