Network café Dynamic Tidal Power
Description
Dynamic Tidal Power.
DTP works with a water level difference of several metres. We generate that height difference by applying Newton's second law (K = m*a), but 'the other way round', so that we convert the acceleration already present in tides, into a force, namely the difference in pressure of the resulting height difference on either side of the very long dam. This dam lies transverse to the sea amidst a tidal current oscillating parallel to the shore. A (simple) video about DTP can be seen on the website of the POWER consortium (www.powerdtp.nl).
Seen from the air, the whole thing looks a bit like the Delta Works, but with dams that are not parallel to the coast but perpendicular to it and with a totally different purpose: namely, large-scale tidal power generation (5 to 10 GW per dam). Two such dams, spaced about 125 km apart, each generate such power, but do so (due to the phase difference between the tides over that distance) with about 90 degrees of phase difference, so that the whole produces an almost constant power.
Between 2 and 3 thousand turbines will be installed per dam, with a capacity of 3 MW (designed by Nijhuis Pumps).
The overall construction of such a dam has been drawn by major Chinese engineering firms (including those responsible for building the Three Gorges Dam).
