  1. 11. Potential of local producing bioenergy/biogas from waste in the municipality of Ragunda

    Kandidat-uppsats, Mittuniversitetet/Institutionen för naturvetenskap, design och hållbar utveckling (2023-)

    Författare :Tomás Hayes; [2023]
    Nyckelord :Bioenergy; Biogas; Biomethane; Global Warming Potential; Rural development;

    Sammanfattning : Population growth, climate change and increased global energy demand has led to the search for environment friendly energy sources. Ragunda Municipality’s major producers of Greenhouse Gas (GHG) emissions are transport, agriculture, and work machines. LÄS MER

  3. 12. The Road Towards Liveable Streets - A transformation along Ystadvägen in Malmö

    Master-uppsats, Lunds universitet/Institutionen för arkitektur och byggd miljö

    Författare :My Harrfors; [2023]
    Nyckelord :Sustainable transportation; urban transformation; mobility; street renewal; Arts and Architecture;

    Sammanfattning : In the end of March this year (2023) UN’s Intergovernmental Panel on Climate Change (IPCC) declared humans are to blame for the 1,1-degree global warming of our planet. Furthermore, that the Paris Agreement will fail. LÄS MER

  4. 13. 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

  5. 14. Numerical modeling of airflow on the cathode-side of a bipolar flow plate : How the formed geometry affects the pressure drop and flow distribution in a hydrogen fuel cell

    Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Olivia Johansson; [2023]
    Nyckelord :Performance; Cross-sectional geometry; Computational fluid dynamics;

    Sammanfattning : Climate change and rising temperatures is a well-known problem. To tackle global warming a transition from fossil fuels to renewable and reliable energy sources is necessary. Hydrogen, in fuel cells, is proposed to replace diesel and gasoline in the transport sector. LÄS MER

  7. 15. 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
