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.


CCell has the ability to generate power from both its forwards and backwards motions. Its hydrodynamically efficient, curved design increases the system's power output, with effective width ratios in excess of 130% 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. CCell's curved design, like the shell of an egg, is structurally efficient, with 90% less material required to achieve the same overall stiffness.

The paddle benefits from extra weight savings by incorporating composite material into the design. The structure is predominantly made from glass fibre composites, which is lightweight 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 and a simple electronic control system.

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