Carnegie MoorPower generates clean energy from ocean waves

This is an interesting case study where energy generated by the movement of ocean waves is stored in batteries for later use.

In this case, we are dealing with a small-scale prototype, but it is fully functional, and both its operation and the results it achieves can be extrapolated to much larger-scale applications.

“We went through a thorough market scanning process, and they came out on top, meeting our technical requirement, with the ability to integrate within our MoorPower Technology.”

How does the system work?

The Moorpower modules are mounted on the deck of a floating asset (e.g. fish-feeding barge, or in this case, a scaled demonstrator). Each module is connected to the seabed via a taught mooring line which is terminated on the module’s drum, connected to the main shaft and generator. This allows to capture and convert the relative motions of the barge into electrical energy.

Carnegiece uses an epic power bidirectional DC/DC converter as part of the solution.

Faced with the challenge of converting marine energy into storable and usable electric energy, the company Carnegie Clean Energy trusted our EPC 3k5 648i bidirectional DC/DC converter solution.

Epic Power converters are capable of detecting when a motor powered by a drive is regenerating energy and storing it in any type of battery. In this particular case, the drives are 600Vdc, and the batteries are 48V, but we can adapt to any drive and any battery.

This function is widely used in other regenerative applications such as elevators or systems with high kinetic energy.

Once this energy is stored and not wasted, you can use it for whatever you need, including powering the same motor from which you recovered it, thereby developing super-efficient systems.

The batteries used for this specific case are Polarium SLB48-050-124-2, which have a capacity of 50Ah.
