With climate change storms are becoming more frequent and ferocious, leading to the accelerated erosion of coastlines. This leaves many coastal communities and low lying area increasingly vulnerable to flooding and property damage.
Existing methods for protecting coastlines, including sea-walls, revetments and dykes, are expensive, use a lot of concrete and rarely look good. By contrast, coral reefs are a natural and sustainable solution, which are known to reduce wave heights by over 70%.
The accelerated growth of reefs, using Biorock technology powered by CCell paddles, provides long-term coastal protection and enhances marine habitats. The CCell paddles both harness and dampen the energy within waves, with excess power (not needed by Biorock) being sold to the local grid, which helps the system pay for itself.
Coral reefs contribute an estimated £108 billion pa to the global economy and provide a habitat for 25% of all known marine species.
The world has lost nearly half of all its coral reefs, with the World Ressources Institute (WRI) estimating that over 60% of the remaining coral reefs are under threat.
Climate change is increasing the stress on corals, with rising water temperatures and acidity lead to coral bleaching and ultimately to their death.
BioRock is a proven technique for both repairing existing corals and building new reefs. The technology uses a small electrical current to extract minerals (mostly calcium carbonate) within the sea water to form rock (often called biological concrete) around a steel wire frames placed on the seabed.
Electricity is the backbone of any modern society, but remote coastal locations often struggle to obtain power, often because of the high costs of importing fuel to power their generators. Across many islands, electricity is 3-4 times more expensive than the power available in developed countries like the UK or USA.
