Wave power harnesses the mechanical energy from ocean waves to generate electricity.
- Special devices, known as wave energy converters (WECs), are placed in the ocean to capture the energy from the waves. These devices are designed to withstand the harsh marine environment and effectively capture the energy of the passing waves.
- As waves travel through the ocean, they cause the WECs to move. There are different types of WECs, but most commonly, they use the up-and-down motion of the waves or the pressure difference between the wave crest and trough.
- The movement of the WECs drives mechanical systems such as pistons, hydraulic cylinders, or oscillating water columns. These mechanical systems, in turn, convert the mechanical energy into rotational energy.
- The rotational energy is then used to drive generators, which produce electricity. The generators can be traditional turbines or other types of electrical generators.
- The electricity generated is fed into the grid for wider distribution to consumers. Alternatively, it can be used for specific localized applications, such as powering desalination plants or offshore platforms.
