Unlike traditional hydroelectric systems, river current technologies use submerged turbines that work with the existing flow of water. The Murray-Darling Basin, Australia’s largest river system, offers particularly exciting potential for these systems, with several pilot projects already demonstrating impressive results in various locations.
These systems are especially valuable in remote communities along major waterways, where they can provide reliable power while maintaining river ecosystem health. The technology typically consists of horizontal or vertical axis turbines, carefully positioned to capture optimal flow rates while allowing fish passage and sediment transport to continue naturally.
Recent innovations in turbine design have significantly improved efficiency, with some systems capable of generating power in water speeds as low as 0.5 metres per second. This makes them suitable for many of Australia’s inland waterways, including sections of the Murrumbidgee and Lachlan Rivers.
The environmental impact is minimal compared to traditional hydropower, as these systems work within the natural river environment. They’re particularly effective during wet seasons when river flows are strongest, providing a complementary power source to solar and wind energy systems.
Maintenance requirements are relatively low, with modern designs featuring self-cleaning mechanisms to handle debris and protective systems to prevent damage during flood events. This makes them an increasingly attractive option for sustainable energy generation in riverside communities.
Tidal Energy Systems
Australia’s vast coastline presents an extraordinary opportunity for harnessing tidal energy, with numerous locations offering ideal conditions for power generation. The Bass Strait, between mainland Australia and Tasmania, stands out as a prime location with its powerful tidal currents reaching speeds of up to 3 meters per second.
Several pilot projects along the northern coast have demonstrated the incredible potential of tidal energy systems. In the Kimberley region of Western Australia, where tidal ranges can exceed 11 meters, studies indicate that tidal power could generate enough electricity to support multiple coastal communities.
The technology works by capturing the kinetic energy of moving water during both incoming and outgoing tides. Modern tidal turbines, similar in appearance to underwater windmills, can operate efficiently in various depth conditions along Australia’s continental shelf. These systems are particularly attractive because they provide predictable power generation patterns, unlike some other renewable energy sources.
Recent assessments suggest that Australia could harness up to 200 terawatt-hours of tidal energy annually. The greatest potential lies in areas such as the Torres Strait, Darwin Harbour, and King Sound, where natural features amplify tidal flows.
