DualSub is a revolutionary device that can simultaneously capture both wave energy and wind energy in a single machine. As a result DualSub has both a high per machine power output, and a more consistent output due to the dual energy sources of waves and wind. We forecast that DualSub can be developed to have a 20+ megawatt power output.

DualSub has all the advantages of WaveSub when it comes to harnessing the power of the waves, with excellent efficiency, survivability and maintainability. The wind turbine will be procured from the world’s leading turbine suppliers, so will keep pace with the latest developments in the market.


DualSub fits with the resource available around the globe: a large proportion of potential sites for ocean energy farms have an abundance of both waves and winds. DualSub is the most space and cost efficient way of obtaining maximum energy from a single machine.

As part of an ocean energy farm, DualSub integrates with WaveSub and WindSub devices to accommodate the different spacing needs for these two energy sources, maximising the output of an ocean energy farm
