    Sammanfattning : In face of climate change, Europe and other global actors are in the process of transitioning to carbon-neutral economies, aiming to phase out of fossil fuels and power industries with renewable energies. Hydrogen is going to play a crucial role in the transition, replacing fossil fuels in hard-to-decarbonize industries and acting as energy carrier and energy storage for renewable electricity.

  3. 2. The effect of ambient lighting combined with EVA warning on driver reaction

    Master-uppsats, Linköpings universitet/Kommunikations- och transportsystem; Linköpings universitet/Tekniska fakulteten

    Författare :Petr Ondomisi; [2023]
    Nyckelord :Ambient lighting; EVA warning message; emergency vehicle; driving simulator experiment; driver behaviour;

    Sammanfattning : Emergency vehicles are at increased traffic risk due to legal exemptions like speeding or running red lights during emergencies. These exemptions can cause delays and complications in their response. LÄS MER

    Sammanfattning : There has recently been an increased interest in hydrogen, both as a solution for seasonal energy storage but also for implementations in various industries and as fuel for vehicles. The transition to a society less dependent on fossil fuels highlights the need for new solutions where hydrogen is predicted to play a key role. LÄS MER

  5. 4. System concept for small-scale biological methanation using electrolysis and trickle bed reactor : with the aim of upgrading biogas to vehicle fuel quality

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Energy and Technology

    Författare :Gustav Larsson; [2021]
    Nyckelord :biological methanation; biogas upgrade; methane; small-scale methanation;

    Sammanfattning : In the present study, the concept of a biological H2 methanation (BHM) system was created for four cases of scale which are determined by electrolyser scale. The system design is aimed to upgrade existing biogas to vehicle fuel quality, with a concentration of CH4 above 95% and H2S removal. The cases of scale and type of electrolyser are: 4. LÄS MER
