  2. 1. Life cycle navigation through future energy carriers and propulsion options for the energy transition in shipping

    Author : Fayas Malik Kanchiralla; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; environmental impact; life cycle costing; battery electric; fuel cells; electro-fuel; technical feasibility; economic impact; hydrogen; life cycle assessment; carbon capture; marine fuel; engines; ammonia; carbon abatement cost; shipping; methanol;

    Abstract : The shipping industry's heavy reliance on fossil fuels has a detrimental effect on the global climate, human health, and the natural environment. The shipping sector now relies on the use of cheap and energy-dense heavy fuel oil and is perceived as ‘difficult-to-decarbonize’. READ MORE

  4. 2. Development of Methanol-Reforming Catalysts for Fuel Cell Vehicles

    Author : Johan Agrell; KTH; []
    Keywords : PEM fuel cells; hydrogen; methanol; reforming; oxidation; reaction pathways; carbon monoxide;

    Abstract : Vehicles powered by proton exchange membrane (PEM) fuelcells are approaching commercialisation. Being inherently cleanand efficient sources of power, fuel cells constitute asustainable alternative to internal combustion engines to meetfuture low-emission legislation. READ MORE

  5. 3. Mathematical Modeling of Transport Phenomena in Polymer Electrolyte and Direct Methanol Fuel Cells

    Author : Erik Birgersson; KTH; []
    Keywords : Fuel Cell; DMFC; PEFC; model; visual cell; scale analysis; one-phase; two-phase;

    Abstract : This thesis deals with modeling of two types of fuel cells:the polymer electrolyte fuel cell (PEFC) and the directmethanol fuel cell (DMFC), for which we address four majorissues: a) mass transport limitations; b) water management(PEFC); c) gas management (DMFC); d) thermal management. Four models have been derived and studied for the PEFC,focusing on the cathode. READ MORE

  6. 4. Electrooxidation of glycerol and methanol on gold

    Author : Mikael Valter; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; van der Waals; electrochemistry; methanol; gold; glycerol; DFT;

    Abstract : Burning of fossil fuels leads to excess CO2 in the atmosphere, causing global warming, threatening civilisation and ecosystems worldwide. As a step in making the society fossil-independent, we need to replace oil, coal, and gas in the transportation sector with fuels originating from sustainable energy. READ MORE

  7. 5. Modelling electrooxidation of glycerol and methanol on close-packed transition metal surfaces

    Author : Mikael Valter; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; implicit solvation; gold; Au 111 ; transition metals; biodiesel; electrochemistry; glycerol; DFT; van der Waals; methanol; scaling relations;

    Abstract : Burning fossil fuels leads to excess CO2 in the atmosphere, causing global warming, threatening civilisation and ecosystems worldwide. As a step in making the society fossil-independent, we need to replace oil, coal, and gas in the transportation sector with fuels originating from sustainable energy sources. READ MORE
