  1. 1. 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.

  3. 2. Performance Analysis of CO2 Heat Pumps in Different Applications

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

    Author : Jaykumar Thanggavelu; [2022]
    Keywords : CO2 Heat pump; COP; District heating; commercial buildings; residential buildings; field measurement data; Propane; Ammonia; R-134a; CO2 Värmepump; COP; Fjärrvärme; kommersiella byggnader; bostadshus; fältmätningsdata; Propan; Ammoniak; R-134a;

    Abstract : This study focuses on researching the performance of CO2 heat pumps in different real-time applications and in some studies, it compares the performance to synthetic and other natural refrigerants based on heat pump data provided from buildings. The research on the performance of the CO2 heat pump is performed based on Sweden's climatic conditions. READ MORE

  4. 3. Transient Flow Simulations in Exhaust After Treatment Systems

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : John Walder; [2020]
    Keywords : Computational Fluid Dynamics; exhaust after treatment system; ammonia mixing;

    Abstract : The exhaust after treatment system is responsible for removing particulates and contaminants from the exhaust gases. The flow entering the SCR, a catalyst utilizing ammonia to reduce NOx emissions, was studied. The quality and distribution of flow entering the SCR plays an important role in the efficiency of the systems. READ MORE

  5. 4. Analysis of Negative Emission Ammonia Fertilizer (urea) Process

    University essay from KTH/Energiprocesser

    Author : Lucio Rodrigo Alejo Vargas; [2020]
    Keywords : Negative emissions; ammonia fertilizer; CO2 capture; process modelling and simulation; biogas; Negativa utsläpp; ammoniak gödsel; CO2-avskiljning; processmodellering och simulering; biogas;

    Abstract : As the world population keeps increasing, ammonia-based fertilizers like urea are essential to provide food security. However, the current fertilizer industry is based on fossil fuel feedstock (mainly natural gas), making the production process CO2 emission-intensive. READ MORE

  6. 5. CFD Simulation of Urea Evaporation in STAR-CCM+

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Oscar Ottosson; [2019]
    Keywords : Urea; AdBlue; SCR; Solid Deposit; NOx; nitrogen oxides; CFD; speedup; spray simulation; UWS; diesel after-treatment; STAR-CCM ; AVL Fire; Scania; Sweden; NXPS; LiU; DOE; Urea; AdBlue; SCR; Klump; NOx; kvävedioxider CFD; uppsnabbning; spray simulering; UWS; efterbehandling av diesel-motor; STAR-CCM ; AVL Fire; Scania; Sverige; NXPS; LiU; DOE;

    Abstract : Diesel engines produce large amounts of nitrogen oxides (NOX) while running. Nitrogen oxides are highly toxic and also contribute towards the formation of tropospheric ozone. READ MORE
