   Sammanfattning : The project Austerland Energi at the eastern tip of the island of Gotland called Östergarnslandet was started as a response to the larger project Omställning Gotland funded by the Swedish government as an effort for a pilot project to convert to renewable energy to reach zero CO2-emissions for the country in 2045. The current plan for the Austerland energy system is a solar PV and wind production base with energy storage in the form of batteries and hydrogen which also can be used as vehicle fuel. LÄS MER

3. 2. Lagerkrafter och friktionsförluster i svänghjulssystem

   Sammanfattning : Reliable energy storage systems are necessary in modern sustainable societies. Storing energy in a spinning flywheel is an old technology which is further investigated in this project. LÄS MER

4. 3. A mechanical analysis of a flywheel as an energy storage system

   Kandidat-uppsats, Uppsala universitet/Institutionen för materialvetenskap

   Författare :Filip Brunmark; Louie Sterin; Yafet Suleman; Groucho Zimmermann; [2021]
   Nyckelord :Energy storage; sustainable energy; mechanics; Energilagring; hållbar energi; mekanik;

   Sammanfattning : This report is a theoretical analysis of high inertia flywheels. Four different flywheel shapes are studied and essential parameters for designing flywheels with optimal energy storage capabilities are discussed. This was done by compiling theoretical findings and presenting these in a way relevant for energy storage applications. LÄS MER

5. 4. Analysis Of A Wave Power System With Passive And Active Rectification

   Master-uppsats, Uppsala universitet/Institutionen för elektroteknik

   Författare :Ferdus Wahid; [2020]
   Nyckelord :WEC; Optimal damping coefficient; Power smoothing; Passive rectifier; Active rectifier; Buck converter; Bi-directional DC-DC converter; Flywheel; Battery; Bi-directional voltage source converter; Voltage source inverter;

   Sammanfattning : Wave energy converter (WEC) harnesses energy from the ocean to produce electrical power. The electrical power produced by the WEC is fluctuating and is not maximized as well, due to the varying ocean conditions. As a consequence, without any intermediate power conversion stage, the output power from the WEC can not be fed into the grid. LÄS MER

7. 5. Techno-economic analysis of integrating renewable electricity and electricity storage in Åland by 2030 : Overview of the current energy situation and definition of four possible environmentally friendly pathways

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

   Författare :Dario Nikzad; [2019]
   Nyckelord :Islanded energy system; renewable energy; electricity storage; energy system modelling;

   Sammanfattning : The study focuses on the possible positive impacts derived from implementing innovative energy solutions to the Åland energy system by 2030. Four scenarios are formulated in order to determine feasible solutions in economic and technological terms. LÄS MER
