Theoretically, about 20% of the wave energy found in the oceans has the potential to meet the world`s electrical energy.
Nearly 18.5 billion kWh / year electricity is can be produced by utilizing one-fifth of Turkey`s coastal wave energy.
Wave Energy Plants turbines can use wave motion, wave pressure or air pressure.These power plants can be established along the coast and on the sea.
WAVE TURBINES
I. System Using Wave Motion
Point Absorbers: It has a sliding structure that moves relative to each other due to wave action. Point Absorber generally likes floating Oceanographic Buoys. They use the rise and fall of the wave at a single point for energy generation. Electromechanical and hydraulic energy converters use the up and down oscillating motion caused by passing waves to generate power.
Reducers: They are multi-part floating structures located parallel to the direction of the waves. The height difference of the waves along the machine causes bending at the points where the parts meet, and this bending is due to hydraulic pumps or other rotators.
II. System Using Wave Pressure ,
The Wave Dropped From Height: It has reservoirs that are filled with incoming waves and cause water pressure like a dam. The water is released and gravity causes it to flow back into the ocean. The energy of the falling water spins the hydro turbines and electricity is generated.
III. System Using Air Pressure ,
Endstops: They lie right angle to the direction of the wave, capturing or reflecting the strength of the wave. These devices are on the shore or by the sea. However, floating versions are also designed for offshore applications. Oscillating water column is a type of endstop that goes under water and keeps the air above. The wave action causes the water column to move up and down like a piston and turbine generate power. These devices generally have power values of 500 kW to 2 MW depending on the device dimensions.
