CCell Renewables Partners with Vicor to Power New Coral Reef Growth

CCell Renewables is a marine natural science company that aims to restore and plant newcoral reefto curb coastal erosion and improve marine ecosystems. More than 70% of the world’s coastlines are eroding, 200 million people worldwide depend on the protection provided by coral reefs, and communities and livelihoods are at risk in many habitats around the world, new data shows.

The CCell reef planting system is based on the electrolysis of seawater, depositing calcium carbonate (limestone) on a large steel frame with anodes and cathodes (electrodes), giving new reefs early structure. This technology is a revolutionary breakthrough, it takes only 5 years to produce an incredible, solid limestone on which corals can grow, instead of hundreds of years. In addition, CCell uses renewable energy sources such as solar, wind and wave energy to power coral reef cultivation systems.

The output voltage of all these renewable energy sources varies widely depending on environmental conditions, which is a major problem in the electrolysis process. The limestone structures in which coral polyps grow must grow at optimal rates, be free of impurities, and have a strong molecular structure. The electrolysis process has to be precise, too slow and nothing will grow; too fast and the limestone can’t sustain. Therefore, distribution networks must be able to adapt widely to extremely challenging environments and operate with a high degree of controllability and accuracy.

Considering the wide variation in input voltage specifications and the need to tightly regulate the potential difference (electric field) between electrodes within the “ideal range” of 1.2V to 4V, and drive a precisely calculated current through seawater. Therefore, Vicor recommends its factorial power architecture (FPA).

By decomposing the DC-DC function into two modules, the PRM regulator and the VTM current multiplier, the regulation and conversion of the distribution network can be optimized.

The PRM buck-boost regulator operates over a wide input voltage and uses a zero-voltage switching (ZVS) topology to achieve very high efficiency and power density. In addition, PRMs can be easily paralleled for higher power. The VTM is a fixed ratio (unregulated) resonant converter with very high current density. The PRM works closely with the VTM, with the PRM tightly regulating the voltage required by the reef, while the VTM handles the step-down switching and the current supplied to the electrodes.

“This complex and unique application has many continuously changing variables that require precise measurement and control to accelerate reef growth,” said Will Bateman, CEO of CCell. “With Vicor’s FPA, we now have a high-performance design. , believe it will greatly improve ecosystems and communities across the planet.”

CCell has always been committed to growing coral reefs around the world and is currently preparing a new 200-meter reef in Mexico.
