It is a fact that sea water continuous to flow in two direction one is perpendicular to the shore and one is parallel to the shore. Dynamic tidal power uses the parallel flow to sea water to produce the electricity. It is most complicate and least sturdy type of tidal power production and it is still in theoretical form no practical work has been done yet. Dynamic tidal power plant is a 30 KM long ‘’T’’ like barrage perpendicular to the shore.
The red section shows the high water tide and blue section the low water tide.
Working of dynamic tidal power
It work just like the tidal barrage the only difference is that the tidal barrage work works with flow perpendicular to the shore and dynamic tidal power works with parallel flow. When the water tide shift the direction after every 12 hour then water start to build up on one side of the wall. When water reached specific height, gates of the barrage is open and water start to flow through the tunnels and make the turbine rotate and the whole process result in the production of clean electricity.
Advantages of dynamic tidal power
- A single unit can produce from 8 to 15 GW power
- Because of its T shape it can produce electricity in any direction of water flow
- It is most reliable that other renewable sources
- It is more efficient than other tidal power types
- It is safer for marine life than tidal barrage
- As head required is lower than the head required for the tidal barrage so it can be installed at low head places where tidal barrage can be installed
Disadvantages of dynamic tidal power
- Its biggest disadvantage is that it is still not tested
- Building a 30 km long barrage need high initial cost
- Although they are less harmful than other tidal but still 30km long barrage can create many problems for marine life
