CHARGING STATION WITH LAND-INDEPENDENT SUBSEA TURBINES

Abstract

Due to the use of fossil fuels, some worrisome problems such as environmental pollution and the extinction of living things have emerged in the world. To find solutions to these, interest in renewable energy sources has increased. In our country, studies are carried out on renewable energy systems and usage of this kind of energy is increasing. Thus, foreign dependencies of our country will be prevented. When we look at the renewable energy research in our country, it is seen that applications related to solar energy, wind energy, and tidal energy are mostly carried out. To obtain energy from the sun, the sun is expected. To obtain energy from wind, there must be wind. To obtain energy from the tide, the sea level must rise. The study is research aimed at meeting the electricity needs of electric marine vehicles independently from land. The subsea turbine obtains electrical energy by converting the flow energy under the sea into rotational energy. The energy taken from under the sea is obtained uninterruptedly at all hours of the day. Although subsea turbines are structurally similar to wind turbines, they differ in many aspects. It has been determined that the energy taken from the turbine, one of which has a subsea current velocity between 2 m/s and 3 m/s, is approximately four times more annual power than the energy taken from an equivalent wind turbine. At the same time, the density of water is 800 times higher than the density of air, and the water flow rate is much lower. This study aims to establish a land-independent power plant, to place a subsea turbine at a depth of 25-30 meters and to charge the battery systems installed on the sea surface by obtaining electrical energy with the least loss from undersea currents through the turbine. Electric marine vehicles, including unmanned sea vehicles, will be able to supply the necessary electrical energy at these stations. There are stations established for the generation of electricity with subsea turbines only for supplying electricity to the land. However, land-independent stations are not yet available in the literature and in practice.
