  1. 1. A Techno-Economic Case Study of the Implementation of Hydrogen Technology in Connection to a CHP Plant

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Kristina Häggström Wedding; Amanda Kander; [2023]
    Keywords : Hydrogen Technology; Electrolyzer; Fuel Cell; Ancillary Services; Electricity Markets; Power Balancing; Balancing Markets; Power to Gas; Power to Power; Combined Heat and Power; District Heat; Heat Utilization; Flexibility; Optimization; Technology and Engineering;

    Abstract : With climate change as the main driving force, the energy system is currently undergoing changes. Both the share of renewable resources used to produce electricity and the overall electrification is increasing. A way to handle the resulting challenges from more intermittent electricity production is by the implementation hydrogen technology. READ MORE

  3. 2. Linking the selectivity of varying surface phases of a real palladium catalyst toward specific methane oxidation pathways with Ambient Pressure X-ray Photoelectron Spectroscopy

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Author : Ulrike Küst; [2023]
    Keywords : APXPS; catalysis; palladium; methane; Physics and Astronomy;

    Abstract : The study of heterogeneous catalysis, especially within methane oxidation, is of high importance in order to more efficiently remove unburned methane from bio-fuel exhausts. This is relevant as bio-fuel engines will replace those driven by fossil fuels in the coming decades. READ MORE

  4. 3. Development of characteristics for electric hydrofoils

    University essay from KTH/Kemiteknik

    Author : Afzaal Bhalli; Carl Fransson; Max Wessman; Sophia Ihrfelt; [2023]
    Keywords : Bränslecell; Batteri; Hybridsystem; Snabbladddning; Bärplansbåt;

    Abstract : Denna rapport belyser två olika perspektiv på hur man skulle kunna lösa problemet med att elektrifiera bärplansbåtar. En tillämpning av bränslecell hybrid som kommer ge upphov till ökad räckvidd samt applikationen av ett snabbladdningssystem för minskad laddningstid vid kortare sträckor. READ MORE

  5. 4. Gas in Scattering Media Absorption Spectroscopy in Large Geometries: Towards Monitoring Oxygen in Adult Lungs

    University essay from Lunds universitet/Förbränningsfysik; Lunds universitet/Fysiska institutionen

    Author : Anna Brandt; [2022]
    Keywords : Physics and Astronomy;

    Abstract : GAs in Scattering Media Absorption Spectroscopy (GASMAS) is a technique to study free gas inside strongly scattering bulk-materials. GASMAS is successful in safely measuring oxygen in lungs of neonates, with low-power tuneable diode-laser spectroscopy at 760 nm. READ MORE

  6. 5. Modellering och simulering av ett robust och resilient biogassystem för ökad försörjningstrygghet

    University essay from SLU/Dept. of Energy and Technology
