Power from the Pulse of the Sea

While solar and wind dominate the renewable energy conversation, the ocean has remained largely untapped. Yet waves hold a dense, consistent energy potential—one that doesn’t fade with the sun or stall with calm skies.

CorPower Ocean, a Swedish-based company, has developed a technology to harness that resource with precision and resilience. Their latest device, the C4 Wave Energy Converter, captures the vertical motion of ocean waves and turns it into usable electricity.

How It Works

The C4 system operates using a point absorber design: a buoy that moves up and down with waves. What makes it different is its WaveSpring technology and adaptive control system. When conditions are ideal, the device "tunes" itself to the frequency of incoming waves to maximize energy absorption. In extreme weather, it detunes to protect itself ensuring both efficiency and durability.

A cascade gearbox inside the unit converts the buoy’s movement into rotational energy, which is then turned into power. Anchored by a seabed-friendly system called UMACK, it’s designed to be both robust and minimally invasive to marine environments.

Key Features

• Adaptive Control: Automatically adjusts to sea conditions for optimal performance.

• WaveSpring Motion Amplifier: Boosts the natural motion of the buoy, improving energy capture.

• Composite Construction: Lightweight, corrosion-resistant materials reduce lifecycle costs.

• Scalable Arrays: Multiple units can be linked into "CorPacks" to serve entire coastal regions.

Tested at Sea

CorPower’s C4 device has undergone real-world testing off the coast of Portugal, where it withstood waves over 18 meters and delivered peak power outputs of 600 kW.

This kind of resilience, paired with its modular design, positions the technology as a viable energy source for coastal nations looking to diversify their grids.
