  1. 1. 3D CFD Simulations of Hydrogen Engine Combustion

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Hao Liu; [2023]
    Keywords : Technology and Engineering;

    Abstract : With the trend of decarbonization, the transport sector is exploring possibilities of fossil fuel free solutions. Hydrogen can be a potential fuel for future engine applications. In this work, the concept of H2 HPDI is investigated, where a pilot diesel injection ignites the hydrogen jet. READ MORE

  3. 2. Life Cycle Assessment of Electric Road Systems - Climate impact in comparison with battery electric vehicles, biogas vehicles and fuel cell electric vehicles

    University essay from Lunds universitet/Miljö- och energisystem

    Author : Ebba Söderström; Emanuel Bengtsson; [2022]
    Keywords : Electric road systems; Elonroad; life cycle assessment; rail; feed-in station; pick-up; on-board charger; climate impact; global warming potential; articulated lorry; lower medium car; bus; Technology and Engineering;

    Abstract : One third of Sweden's total annual greenhouse gas emissions originate from the transport sector today and great changes are thus needed in order to reach the net zero emission target by 2045. One of the most important measures discussed is an increased electrification of the transport sector and a solution with potential to contribute to this transition is electric road systems (ERS), where vehicles are charged dynamically.

  4. 3. Strategies for regional deployment of hydrogen infrastructure : The case of North Rhine-Westphalia, Germany

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

    Author : Roberto Di Molfetta; [2022]
    Keywords : Hydrogen; Infrastructure rollout; Supply chain pathways; Mobility; Hydrogen buses.;

    Abstract : In response to the growing urge towards decarbonisation, more and more initiatives have been set to reduce and/or compensate the level of CO2 (carbon dioxide) emitted by human activities, which is one of the main responsible of the incumbent threats of “global warming” and “climate change”. “Climate neutrality by 2050” has become a decisive topic for political agendas worldwide and, against that background, the hydrogen economy can play a significant role.
