Wave Energy – Marine Energy Generation Systems Using the Motion of the Waves

Three main technologies covering three different physical principles: converting wave energy into electricity is a challenge to be solved with ingenuity and innovation

The marine energy contained in waves (Wave Energy) comes from the force wind exerts on the surface of the sea, leading to the formation of ripples on the water’s surface. These ripples add up to produce the intermittent surface motion of waves.

This phenomenon is greater on the surface, decreases deeper down, and disappears completely before it reaches deep sea floors. WECs (Wave Energy Converters) capture energy from waves using different physical principles:

Wave Activated Body

The motion that waves exert on a body is taken and transmitted to a system that turns this mechanical energy into electrical energy (turbines or electrical converters).


Involves the use of energy related to breakwater barriers, where the water that touches the barrier is accumulated in a tank and then passed through a hydraulic turbine.

Oscillating Water Column

The intermittent variation of the level of a water column is used, created inside a special chamber connected to the sea, which then compresses an air mass, in turn activating a turbogenerator.

WEC technologies are in the pre-commercial development phase. It’s not yet clear which technology will be most suitable for widespread use in marine energy generation.
