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 areas increasingly vulnerable to flooding and property damage.
Existing methods for protecting coastlines, including seawalls, 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 84% on average.
The accelerated growth of reefs using Biorock technology powered by CCell paddles, provides long-term coastal protection and enhances marine habitats. The CCell paddle both harnesses and dampens the energy within waves, with the potential for excess power (not needed by Biorock) to be supplied to local micro-grids.
Coral reefs contribute an estimated £108 billion per year to the global economy and provide a habitat for 25% of all known marine species.
Unfortunately, the world has lost over half of all its coral reefs, with the World Ressources Institute (WRI) estimating that 75% of the those remaining are under threat.
Climate change is increasing the stress on corals, with rising water temperatures and acidity leading 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, usually 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.
In many regions, especially remote islands, implementing solar energy solutions at a large scale can be hindered by a limitation on the amount of land space available. Wave energy can be used in these regions to complement solar technologies, reducing the number of panels and the amount of battery storage required.
