6. Tidal Range
Tidal range, the vertical difference between high and low tides, is a critical factor determining the potential for tidal energy generation. As a key parameter influencing the economic and technical feasibility of harnessing marine energy, it directly dictates the amount of energy that can be extracted from tidal currents or impounded water. Therefore, tidal range stands as a fundamental consideration when evaluating the viability of employing tidal energy technologies as components of power from replenished origins.
- Tidal Barrages
Tidal barrages, dam-like structures built across estuaries, capitalize on tidal range by impounding water during high tide and releasing it through turbines during low tide. The greater the tidal range, the larger the head difference across the barrage, and the more electricity can be generated. La Rance Tidal Power Station in France, for example, exploits a significant tidal range in the Rance Estuary to produce power. The efficiency of tidal barrages is heavily reliant on substantial differences in water level, limiting their applicability to regions with limited fluctuations.
- Tidal Stream Generators
Tidal stream generators, similar to underwater wind turbines, harness the kinetic energy of tidal currents. While tidal range does not directly influence the energy capture of these generators, it often correlates with stronger tidal currents. Areas with large tidal ranges tend to exhibit faster tidal currents as water is forced through constricted channels, creating favorable conditions for deploying stream generators. The Pentland Firth in Scotland, known for its strong tidal currents resulting from a constricted channel, is a site for stream generator projects.
