1. Increasing Energy Efficiency in Electric Trains Operation : Driver Advisory Systems and Energy Storage
Sammanfattning : Electric traction is the most efficient traction system in the railway transportation. However, due to the expensive infrastructure and high power demand from the grid, the share of electric trains in the railway transportation is still lower than other trains. LÄS MER
2. Energy transition in transportation : Applying TIMES-based energy system optimisation models to sub-national levels
Sammanfattning : Transportation is embedded in the fabric of society and a key enabler of socio-economic development, but it is also a major source of carbon dioxide (CO2) and local air pollution (AP). Cities collectively account for around three quarters of total energy-related CO2 emissions, and the negative health impacts from local APs are most felt in dense urban environments. LÄS MER
3. Designing Energy-Sensitive Interactions : Conceptualising Energy from the Perspective of Electric Cars
Sammanfattning : As technology is increasingly used in mobile settings, energy and battery management is becoming a part of everyday life. Many have experienced how quickly a battery can be depleted in a smartphone, laptop or electric cars, sometimes causing much distress. LÄS MER
4. Decentralization in energy systems - Low-carbon technologies and sector coupling on the household, community and city scales
Sammanfattning : The number of installations of distributed energy technologies, such as solar photovoltaic (PV) and battery systems, has increased dramatically in recent decades. The required transition towards a decarbonized energy system entails electrification of the different sectors. LÄS MER
5. Natural resources and sustainable energy : Growth rates and resource flows for low-carbon systems
Sammanfattning : Large-scale deployment of low-carbon energy technologies is important for counteracting anthropogenic climate change and achieving universal energy access. This thesis explores potential growth rates of technologies necessary to reach a more sustainable global energy system, the material and energy flows required to commission these technologies, and potential future availability of the required resources.
