  2. 1. Electrochemical reduction of protons and organic molecules in hydrogen technologies : Liquid Organic Hydrogen carrier and Hydrogen Evolution

    Author : Hamid Ghorbani Shiraz; Magnus Berggren; Xavier Crispin; Ola Wendt; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hydrogen Storage; LOHC; Hydrogen Evolution; Electrocatalyst;

    Abstract : In accordance with preventable actions to mitigate the effect of climate change in the modern societal applications, renewable energy is an unavoidable and decisive factor in the energy industry. The energy sources that offer non-depleted and environment-friendly pathways for the energy sector are in focus. READ MORE

  4. 2. Hydrogen generation from dimethyl ether by autothermal reforming

    Author : Marita Nilsson; Lars Pettersson; Ann Cornell; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; autothermal reforming; auxiliary power unit; dimethyl ether; fuel cell; hydrogen; palladium; reforming catalyst; temperature-programmed reduction; truck idling; X-ray diffraction; zinc; Chemical engineering; Kemiteknik;

    Abstract : Heavy-duty trucks are in idle operation during long periods of time, providing the vehicles with electricity via the alternator at standstill. Idling trucks contribute to large amounts of emissions and high fuel consumption as a result of the low efficiency from fuel to electricity. READ MORE

    Abstract : Heavy-duty trucks are in idle operation during long periods of time, providing the vehicles with electricity via the alternator at standstill. Idling trucks contribute to large amounts of emissions and high fuel consumption as a result of the low efficiency from fuel to electricity. READ MORE

  6. 4. Hydrogen, an Energy Carrier of the Future

    Author : Christian Hulteberg; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical technology and engineering; Catalysts; Aerosols; Gasification; Hydrogen; Systems; Kemiteknik och kemisk teknologi;

    Abstract : The climate is changing, something that many scientists correlate to increased emissions of greenhouse gases. The effluent that is considered to have the highest impact on global warming is carbon dioxide, when effect and quantity are taken into account. READ MORE
