How it works- CorPower Ocean Wave Energy Converters

CorPower Ocean Wave Energy Converters

The video explains how CorPower Ocean’s wave energy converters harness clean energy from ocean waves, one of the largest untapped renewable sources. The technology uses a heaving buoy inspired by the human heart’s pumping principle, based on 40 years of hydrodynamic research. This results in a lightweight, low-cost design optimized for high energy generation and durability in harsh ocean conditions.

Key Technological Features

• Energy Conversion: Wave energy is converted into rotational motion inside the buoy, which is then transformed into electricity by internal generators.

• Phase Control Technology: A novel system allows the buoy to be tuned or detuned depending on sea conditions:

  • In regular sea states, the buoy is tuned to amplify wave motion (e.g., a 1-meter wave is amplified to 3 meters), increasing efficiency.
  • In storm conditions, the buoy is detuned to become transparent to waves, protecting the system from damage. This is similar to how wind turbines pitch their blades to avoid overspeeding.

Product Specifications and Deployment

• Each wave energy converter measures 9 meters in diameter and 19 meters in height.
• Each unit has a 300 kW power rating.
• Units are anchored to the seabed using a tensioned mooring system with a tidal regulator.
• Multiple units can be deployed in large arrays or wave farms, capable of generating hundreds of megawatts, sufficient to power hundreds of thousands of homes.
