16. Energy Efficiency through Thermal Energy Storage : Possibilities for the Swedish Building Stock
Sammanfattning : The need for heating and cooling in buildings constitutes a considerable part of the total energy use in a country and reducing this need is of outmost importance in order to reach national and international goals for reducing energy use and emissions. One important way of reaching these goals is to increase the proportion of renewable energy used for heating and cooling of buildings. LÄS MER
17. Supermarket refrigeration systems for demand response in smart grids
Sammanfattning : With an increasing share of intermittent renewable energy sources in the electrical grid, the need for adapting the demand to the available supply of electricity becomes increasingly important. Within this thesis, the demand response capacity by supermarket refrigeration systems are investigated and methods for enabling it is developed. LÄS MER
18. 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
19. Norbornadienes for Solar Thermal Energy Storage and New Applications
Sammanfattning : The energy demand worldwide is steadily increasing, therefore it is fundamental to efficiently utilise renewable energy resources. Energy storage technologies are partic- ularly relevant in order to be able to exploit renewable energy resources such as solar energy, since these are typically intermittent and not evenly distributed.

20. Transition pathways for future district heating and cooling systems with thermal energy storage
Sammanfattning : Buildings’ heating and cooling account for more than 20% of the final energy use within the European countries and are dominated by non-renewable resources. Future district energy systems should enable efficient, fossil-free, and economical energy supply at operating temperatures that end users can directly utilize. LÄS MER
