CCell uses an underwater electrical process, which uses a safe low-voltage current, to convert seawater minerals (mostly calcium carbonate) into limestone rock that forms around a steel structure. This process yields a type of "natural concrete" or rock that can be grown in virtually any shape or size.
The rock grows at a rate of approximately 2.5cm (1") per year around the steel, forming a strong structure similar to reinforced concrete.
With over 500 installations globally, this electrolytic process has been proven over 25 years to significantly accelerate coral growth. Fragments of broken or farmed corals, attached to the structure, can grow up to 5x faster than natural reefs. This technique is the principal method by which the Global Coral Reef Alliance have restored corals over the last 25 years.
The method has been uniquely applied to solving a wide variety of marine and coastal problems including coral reef and fishery habitat restoration, shoreline protection, and erosion control measures.
