Dynamic Tidal Power

Dynamic Tidal Power (DTP) defines a new concept to exploit the power of tidal waves. Existing tidal energy concepts apply either the given vertical tidal range or the given horizontal tidal stream velocity to generate electricity. By contrast, Dynamic Tidal Power additionally considers and exploits the acceleration of tidal streams.

The typical infrastructure fitting for DTP is a very long solid T-shaped dam built out perpendicularly to a shoreline amidst oscillating, and hence accelerating, tidal streams. This dam creates a pair of tidal waves on either side, that together generate a hydraulic head pushing against the dam. This hydraulic head can be used to generate electricity by making openings in the solid dam and installing efficient bi-directional turbines. The total capacity of the dam (installed GW) turns out to grow exponentially with the dam length, a good reason to plan very long dams (20 to 100 km).

In practical terms, the infrastructure required to generate dynamic tidal power is directly building on centuries of experience as shown by the Dutch Delta Protection Project with its long barriers constructed in deep water using sophisticated floating caissons. Because dynamic tidal power doesn't require a very high natural tidal range, more sites are suitable for this form of tidal energy generation. The energy that could potentially be generated in this way is about 10 gigawatts (GW) for a 50 km long dam.
