How do you store tidal energy.. is it easy?

Question

thanks for answering!!

Answer 1

As was mentioned here, damming a basin or estuary will do it, but the environmental impact must be considered. Messing with tidal cycles will alter the environment in the immediate area, no doubt, but as was discovered in Maine and Nova Scotia, in the 60's (after a lengthy and expensive construction investment) damming a channel between two small islands to make a high-velocity current would flood a city (Boston) 200 miles away by increasing the tidal height elsewhere.

Great ideas, but the impacts are costly!

Answer 2

If you have a generator you could convert tidal energy into electricity and store it in batteries.  Essentially capture the water at high tide and once there is a low tide release the water back and gain the energy from the water flowing back out.  Also as tides go in and out they create a current and you can get electricity from putting a generator at the places where the current is the strongest.

Answer 3

Choose  a place where there is big difference between high tide and low tide.  Fill a basin with water during high tide releasing the water through a low head turbine to recover the energy.  

In engineering you use tidal gates which open as the tide rises and close when the tide begins to recede.
