How wave energy works


If you are wondering what theoperation of a wave power plantyou are in the right place.

L'wave energyit represents a completely unexplored potential. Of course, there is no lack of calculations and estimates but in practical terms, when it comes to popularity and number of plants, thewave energyit has only a handful of pilot projects. Everyone knows - broadly speaking - that a wind turbine has blades connected to an electric generator, just as a ray of sunlight can be transformed into electricity thanks to a series of silicon panels, but how wave energy works?

In our article "Wave energy "we have seen the various types of systems, today we try to analyze the operating scheme of this technology that is still so little widespread and known.

Waves are the movement of water near the surface of the sea and are formed as a result of the action of the wind. There are many systems capable of exploiting thewave energyto produceelectricity. The two main ones see oscillating water columns or point absorbers.

How energy is produced from waves? The swinging columns
The oscillating water columns are systems that contain a turbine. In this case, the underlying waves work like a pressure piston where the wave motion pushes the air up and down, setting in motion the turbine connected to a generator that produces electricity.

How energy is produced from waves? Point absorbers
Point absorbers are able to capture energy by moving in tune with the waves. This movement can be used to pump water or other liquid through a turbine which, again, is connected to an electricity generator.

This model of operation is the one seen with the Pelamis generator off the coast of Portugal. These generators produce energy consistently but, contrary to many otherswave motion systems,they have a considerable size.
