1. 1. Investigating the dynamics between the developing Nordic hydrogen market and the electricity system under uncertainty

   Master-uppsats, KTH/Energiteknik

   Författare :Timon Renzelmann; [2024]
   Nyckelord :energy modelling; energy storage; global sensitivity analysis; hydrogen; Method of Morris; Nordics; OSeMOSYS; uncertainty analysis; energimodellering; energilagring; global känslighetsanalys; vätgas; Morris-metoden; Nordiska länder; OSeMOSYS; osäkerhetsanalys;

   Sammanfattning : The potential of hydrogen as a clean energy carrier is hotly debated, but it promises to significantly contribute to a sustainable energy future. Hydrogen can replace fossil fuels in carbon-intensive industries, heavy transport and aviation, and support a renewable energysystem by acting as energy storage to balance intermittent supply.

3. 2. Solar Photovoltaic Thermal Collectors and Ground Source Heat Pumps for Commercial Buildings : Case study in Sweden

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

   Författare :Doris Dijak; Elin Torstensson; [2023]
   Nyckelord :Ground Source Heat Pump; Photovoltaic Thermal Collectors; Borehole Thermal Energy Storage; Free Cooling.; Bergvärmepumpssystem; Termiska Solceller; Borrhålsbaserade Termiska Energilager; Frikyla.;

   Sammanfattning : In order to reduce emissions from the building sector, which stands for than a fifth of the global energy consumption today, efficient and fossil free heating and cooling systems are of importance. This study investigates the combination of solar photovoltaic thermal collectors and ground source heat pump systems in order to regenerate energy to the ground in combination with free cooling.

4. 3. Optimization of Thermal Comfort on Electric Buses : A Comprehensive Study on Passenger Satisfaction in Stockholm, Sweden

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

   Författare :Ellinor Hambraeus; Maxwell Minotta Cuervo; [2023]
   Nyckelord :Electric bus; Bus temperature; Thermal comfort; Energy efficiency; Predicted Mean Vote; Equivalent temperature v; Elbuss; busstemperatur; termisk komfort; energieffektivisering; Predicted Mean Vote; Ekvivalent temperatur vii;

   Sammanfattning : The transition towards electrification in the bus sector is necessary to achieve the global climate goals and has gained significant traction in recent years. However, there are critical challenges associated with this transition, one of them being the absence of excess heat that traditional combustion engines provided to warm the bus cabin. LÄS MER

5. 4. Pathways towards universal access to electricity in West Africa : Case study of Mali and Senegal

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

   Författare :Vittorio Bozzo; [2023]
   Nyckelord :Universal electricity access; Senegal; Mali; OnSSET; GIS; PV mini-grid; Universell tillgång till el; Senegal; Mali; OnSSET; GIS; PV mininät;

   Sammanfattning : Despite the vast solar potential in both Mali and Senegal, the electricity access in both countries remains one of the lowest in the world. The main problem is represented by the disparity between rural and urban settlements. In Senegal, the electricity access for rural areas was lower than 50%, while in Mali was around 35%. LÄS MER
