CorPower Ocean is a leading wave energy technology developer utilising forty years of ocean energy research to bring a new class of high-efficiency Wave Energy Converters to market, enabling robust and cost-effective harvesting of electricity from ocean waves. This videos explains the working principle of the CorPower C4 technology.

CorPower Ocean’s wave energy converters harness clean energy from the world’s largest untapped energy source – our oceans. The wave motion is turned into rotation, which is converted into electricity by generators inside the buoy.

With 300kW power rating, the new device is said to represent the world’s most compact wave energy system in relation to power output. The buoy is connected to the seabed using a tensioned mooring system. Novel phase control technology makes the compact devices oscillate in resonance with the incoming waves, strongly amplifying the motion and power capture.

The system has improved survivability in storms, thanks to its inherent transparency to incoming wave energy in long storm waves. The human heart uses stored hydraulic pressure to provide force for the return stroke, thereby only requiring the muscles of the heart to pump in one direction.
In a similar way, our Wave Energy Converters use a pre-tension system to pull the buoy downwards. Wave swells push the buoy upwards, while the stored pressure provides return force to drive the buoy downwards. This results in an equal energy production in both directions and a lightweight system that is naturally transparent to ocean waves (detuned) unless actively controlled.
