Tidal Power

Sammanfattning: Tidal power is a relatively new area within renewable energy with great potential in some areas of the world. One of the companies working with this is Minesto, and they have developed a technology called Deep Green that uses a kite that is attached to the seabed to generate electricity. The purpose of this project is to research technologies for production of electricity from tides and under water streams and also to describe the Deep Green technology, compare it to other technologies and propose some suggestions to the current solution. The study is separated into two parts and begins with a research faze on Minesto and other companies that have projects within tidal energy. The other section is a modelling faze where models that describe the Deep Greens movement are made. Forces that the system is exposed to are also calculated for further dimensioning of the components. The research revealed that Minesto has some advantages in comparison to the other companies that were looked at. The largest ones were that Deep Green can produce electricity effectively at low water speeds and that the power plants are relatively light. The Modelling showed that the wing moves closer to the seabed at higher water speeds and that some of the components in the system are over dimensioned and could be designed to be lighter.
