Why not use pumped storage? What is needed is elevation to overcome the head-deficiency inherent to the equilibrium periods. This is achievable by sacrificing some of the stored water, to pump a smaller amount of water to a higher elevation.
- streety 18y agoA valid point. A similar approach can be taken for solar and wind. Use excess energy to pump water into a higher reservoir which can be released during overcast/still periods. The only difference I can see being that with tidal you know exactly when the next burst of energy will come and how large it will be.
- DaniFong 18y agoPumped storage is quite low capacity and low efficiency for the cost and surface area. 1 kg, that is, 1 liter of water, up 20 meters, is only 200 joules. An apple laptop uses 40 watts: which is that amount every five seconds.
