Types of Wave Energy Conversion Systems
There are different types of wave energy conversion systems, including:
- Point Absorbers: These systems use buoyant devices that move up and down with the wave motion, driving a power take-off system to generate electricity.
- Attenuators: These systems consist of multiple connected segments that move with the waves, generating electricity through hydraulic or mechanical systems.
- Overtopping Devices: These systems use wave action to fill a reservoir, and the stored water is released through turbines to generate electricity.
