How is CCell Different?

Its curved asymmetric shape delivers a step-change in performance in three ways:
CCell with large wave


CCell's curvature channels the wave energy towards a strong central core, amplifying the power extracted from the waves while protecting the device against extremes. more..

CCell with feather


CCell's curved structure is naturally strong (just like the shell of an egg), making the device 25x lighter for the same strength. more..

CCell with Streamlines


CCell is designed for simplicity, with a modular approach that makes it quick and easy to manufacture, deliver and assemble onsite. more..


CCell has the highest known power to weight ratio of any wave energy device. In trials effective width ratios in excess of 130% have been measured.

This power arises from the flexible curved guides of the CCell paddle that focus the incoming waves towards a strong central core, driving the paddle forward and backward. Similarly, CCell’s convex shoreward face cuts smoothly through the water, reducing energy dissipation from this face. This motion is consequently converted into electrical power.

A distinguishing feature of CCell is the smooth transition of energy from the waves to the paddle, which reduces turbulent losses and slamming loads. The device also has remarkable survivability in extreme waves, with excess energy smoothly channelled over the device.


CCell has the highest known power to weight ratio of any wave-energy device.

A curved structure is naturally stiffer than the flat equivalent for the same width, with 90% less material required to achieve the same overall stiffness.

The device is predominantly made from glass fibre composites, which is light weight and highly durable in the marine environment.


The sea is a complex environment, so it is essential that the system works reliably, with minimal maintenance and attention.

Working closely with manufacturers and marine contractors we continually strive to simplify manufacturing, installation and maintenance activities. The device itself consists of ten parts, a simple electronic control system.

Innovate construction techniques allow the majority of the paddle to be made locally, reducing transportation costs, while supporting local industry.
