The Subwave Concept

Ocean waves are a surface phenomenon. If the depth is more than half the wavelength of the waves, the body of water is virtually at rest, no matter what the conditions are on the surface

The Subwave turbines hang freely from buoys at the surface, way below the zone affected by waves. In the stagnant body of water at the depth wave energy will be converted into electrical energy from the buoy motions at the surface.

A large number of interconnected Subwave units can harvest wave energy from wide ocean areas simultaneously. In this way it is possible to produce electrical energy in a magnitude that really matter.

The potential of the oceans

The Subwave units will be deployed and linked together by common offshore service vessels, without any subsea operations.


  • The simple construction of the Subwave turbine leads to a lower price compared to more complicated offshore power solutions.
  • Because the turbines is installed a long way below the waves it is safely out of the way of winter storms. This is a common failure point for previous wave energy ideas.
  • The high costs associated with sub sea maintenance is negated by the fact that the Subwave turbines hang from surface buoys, so it is easily accessible by vessels on the surface.
  • The entirely offshore nature of the Subwave technology means there is no need for any onshore installation.

Floating factories in the northern and southern westerlies (green, yellow and red areas), powered by large Subwave installations, can produce hydrogen from electrolysis of water. This will be a business that technologically will have much in common with the offshore oil and gas industry.
