WaveSub is a class-leading wave energy converter that can generate high levels of consistent, low cost power. WaveSub benefits from all the generic advantages of our platform technology and has its own unique advantages when it comes to harnessing wave energy.

Powerful and Efficient

WaveSub has a unique orbital energy capture mechanism – directly and efficiently harnessing the subsurface orbital energy flow of the waves. Each energy capture float can capture over 1.5 megawatts of power, and each WaveSub device has multiple floats, leading to significant multi megawatt power output per machine. With the rated power of the first commercial generation starting at 4.5MW, increasing to circa 10MW in future generations, WaveSub is the only WEC with a power output and cost profile that is comparable to modern wind turbines.

WaveSub can survive storms by retracting the float securely against the base deep underwater, well beneath the harsh conditions on the sea surface.

Tested Technology

WaveSub has been tested at quarter scale at the marine test site FaBTest in Cornwall, UK. WaveSub demonstrated its ability to generate grid compatible electricity from the waves. The quarter scale test also demonstrated the many practical advantages of our platform technology, proving straightforward transportation, installation and maintenance on-site without needing any specialist vessels.

Alongside the sea testing the performance of WaveSub has been further improved with 1000’s of hours of computational simulations and a tank testing program equivalent to several months of non-stop testing.
