Our Technology

Using advanced engineering to grow beautiful reefs.


Wave power has an energy density more than 800 times that of wind, which we efficiently harness using the CCell-Wave paddle. With the highest known power to weight ratio of any wave energy device, our wave-energy converter consists of a composite paddle hinged at the seabed that drives a hydraulic system to generate electricity.

CCell-Wave has a simple and sturdy design, inspired by nature. The curve of our paddle is naturally strong and able to withstand extreme conditions, while composite materials make the paddle light-weight and durable. It was even tested in Cozumel during hurricane season. The paddle is adaptable and through minor adjustments during manufacture, it is optimised for the prevailing site conditions adjacent to the growing reef.

Smart Power Management

After CCell-Wave has captured energy it must be dispersed over the reef. To extract calcium carbonate from seawater with electrolysis, the voltage applied to the steel reef structure must be between 1.2 and 4 volts. Any less and electrolysis can not take place, any more and the rock being formed becomes spongy and less suitable for coral growth. The power CCell-Wave can capture will also vary day-by-day depending on weather and tidal conditions.

The Smart Power Management (SPM) continually optimizes the power output, controlling the distribution of power across the reef and matching supply with demand to grow strong limestone rock at maximum rates at all times.

Artificial Reefs

Reefs act as natural barriers to erosion by causing waves to break out at sea, taking away up to 97% of their energy before they hit the shore.

This works to prevent coastal erosion and promote a healthy beach by knocking out the large waves which tend to remove sand from beaches while allowing the small waves to deposit sand onto the beach.

The CCell system works by passing a safe low-voltage current through a steel structure. Seawater minerals (mostly calcium carbonate) are drawn to the structure, forming strong limestone rock around it. This fast process grows rock at approximately 2.5cm (1") per year and has been used at almost 500 sites around the world.

Accelerating coral growth

Building on over 25 years of research, this process has been shown to accelerate coral growth: fragments of broken or farmed corals attached to the structure can grow faster than on natural reefs. This method of reef-creation has been applied to solving a wide variety of marine and coastal problems, including coral reef and fishery habitat restoration, shoreline protection, and erosion control measures.

Our partners at the Living Reefs Foundation have been researching the effects of our electrolysis technology on the growth of young corals, intending to optimise this process.
