1. 1. Development of an Accelerated Test Method for Compressed Natural Gas Fuel System Robustness against Contamination

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Författare :Elias Aretorn; [2023]
   Nyckelord :CNG; Natural Gas; Heavy-Duty Vehicles; Fuel System; Contamination; Cleanliness; Accelerated Testing; Experimental Setup; Pressure Regulator;

   Sammanfattning : A key factor for driving the shift towards sustainable transportation systems is alternative fuels, where compressed natural gas (CNG) is a beneficial alternative to the conventional fossil fuels with respect to greenhouse gas emissions. A fuel system is needed for heavy-duty natural gas vehicles, in order to transport the highly pressurized gas from the fuel tanks to the internal combustion engine. LÄS MER

   Författare :Lucas Chaubier; [2022]
   Nyckelord :;

   Sammanfattning : In the United Kingdom, 85% of households rely on natural gas for space/water heating and cooking. On average, the yearly demand for one household for providing heat from natural gas is 13300 kWh. LÄS MER

5. 4. Simulation of decarbonization objectives for the district heating system in the Helsinki metropolitan area

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Yijie Su; [2021]
   Nyckelord :District heating; CO2 emission; Decarbonization goal; Helsinki metropolitan area; EnergyPRO; Fjärrvärme; CO2-utsläpp; Dekarboniseringsmål; Helsingfors storstadsområde; EnergyPRO;

   Sammanfattning : District heating (DH) is of great significance for the Nordic countries due to the high heat demand especially in the winter. In Finland, 40% of heat was generated by fossil fuels in DH system, and DH sector emits 10% of the total emissions. The Finnish government aims to achieve carbon neutrality as the national goal by 2035. LÄS MER
