 Marine Energy - Wave, Tidal, Thermal power, Offshore Wind and Thermal Power

Marine energy is any form of renewable energy that is generated through use of the marine environment. Types of marine energy include:

  • Wave energy from the motion of surface ocean waves or
    below-surface pressure
  • Tidal energy from naturally occurring tidal currents
  • Offshore wind from turbines in coastal areas
  • Ocean thermal from the temperature difference between deep and shallow water

Wave Energy
Wave energy is generated by the movement of turbines and devices floating on the ocean surface. Wind blowing across the ocean surface creates waves. The stronger the wind, the higher the wave energy, the greater the potential for the development of electricity.

The west coast of Victoria offers the best potential for the siting of turbines but a significant number of considerations affect the siting and installation of wave energy devices.

Tidal Power
The areas of most significant tidal change in Victoria occur in eastern Victoria where tides of between 2 and 4 metres are experienced. Current tidal generation technology requires tidal variation of 7+ metres restricting application of the technology to the north-west of Australia.

Technically, future potential also exists at the narrow entrances of significantly large bays and inlets such as Port Phillip Bay, Westernport Bay and Corner Inlet. A significant number of considerations would however affect their siting and feasability.
