  1. 1. Conceptual design of the next generation gas turbines : Modelling of a hybrid electric mixed turbofan for a trainer aircraft

    University essay from Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Author : Sophia Fisher; Michael Åkerström; [2023]
    Keywords : Hybrid propulsion; mixed turbofan; parallel configuration; performance;

    Abstract : To mitigate climate change, all sectors must contribute their part. Electric propulsion system is a promising approach to reduce emissions from the aviation industry. A major challenge is however the low energy density in today’s battery technology. READ MORE

  2. 2. Dimensionering av krisberedskap för elbilsladdning : en simuleringsstudie om krisberedskap för samhällsviktiga funktioner

    University essay from SLU/Dept. of Energy and Technology

    Author : Linus Christiansen; [2023]
    Keywords : krisberedskap; samhällsviktig verksamhet; personbilstransport; elfordon; elektrifiering;

    Abstract : With the rising number of electric vehicles in the Swedish vehicle fleet in combination with the rising electricity demand in the country, it begs the question. How should the electricity demand from charging of electric vehicles for vital societal functions be managed in a time of crisis without the support from the electric grid? This study focuses on the task of dimensioning reserve power systems for electric vehicle (EV) charging of parking spaces with 10, 20 and 30 cars. READ MORE

  3. 3. Reprocessing and Characterization of Polybenzimidazole for High-Temperature Polymer Electrolyte Membrane Fuel Cells

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Douglas Björkengren; [2023]
    Keywords : polymer electrolyte membrane fuel cells; PEMFC; HTPEMFC; polymer technology; polymer characterization; reprocessing; recycling; polybenzimidazole; PBI; Technology and Engineering;

    Abstract : A reprocessing method of poly(2,2’-(m-phenylene)-5,5’-bibenzimidazole) (PBI) membranes recovered from the production line of High-Temperature Polymer Electrolyte Membrane Fuel Cells (HT-PEMFC) at Blue World Technologies (BWT) has been developed in order to reduce material loss in the production. Redissolution of scrap PBI membranes in poly(phosphoric acid) (PPA) and phosphoric acid (PA) was successful and the subsequent washing procedure produced PBI that could be redissolved in N,N-dimethyl acetamide (DMAc) and suitable for solution casting of new membranes.

  4. 4. Electrical transition of the automotive industry : A case study of a Swedish automotive tool manufacturer

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Oscar Brönmark Riex; Jakob Holm Bjelke; [2023]
    Keywords : Market analysis; Automotive industry; Manufacturing; Powertrain; EV; ICE; Marknadsanalys; Fordonsindustrin; Tillverkning; Powertrain; EV; ICE;

    Abstract : The need for sustainability solutions requires a shift towards renewable energy and less dependence on fossil fuels, exemplified by the EU’s Green Deal targeting zero greenhouse gas emissions by 2055. This shift creates uncertainties in the global economy, and it recently sparked the automotive industry’s move from the internal combustion engine (ICE) to the electric vehicle (EV). READ MORE

  5. 5. Energy demand and biogas production in rural areas : A case study in the Raqayapampa community in Bolivia

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Halvor Solheim Haugen; Noel Arancibia Holm; [2023]
    Keywords : ;

    Abstract : Improved access to energy can greatly improve living standards, and there are correlations between increased access to electricity and higher scores on both the Human Development Index (HDI) and the Educational Development Index (EDI). Increasing access to energy can also help decrease dependability on hazardous fuels and energy sources, such as firewood for cooking. READ MORE
