Ladies and Gentlemen,
the matt 'n' fionn plan for storing renewable energy
is as follows.
Take one windfarm on a hill somewhere,
or one underwater tidal current farm.
When electricity production is high,
and consumer demand is low, like at night....
Switch the power to raising water, like in turlough hill

except this time the energy used to raise the water is renewable.
A coastal tidal current generator like the davis energy turbine,www.bluenergy.com , could also be used purely in conjunction with a mechanical pump, with no electrical generator attached, to pump water up into a reservoir on a cliff, ready for release down onto a turbine just above sea level.
remember you can use either the route by which you generate electrical power, to run the pump, or physically connect the moving parts of the windmill or undersea mill to the pump.
this is the much talked about battery, that renewable energy has required to become effecient and effective.
best regards
Fionn

Grand Coulee stores water in the Grand Coulee by pumping it up from Lake Roosevelt (the lake behind the dam). The pumps can also operate in reverse (i.e. as generators), providing peak generation capability. My point being the idea is not new.
Yes, your idea makes sense as a power storage system. You still need a place to create a reservoir, and deal with the people displaced by the lake you create. I've also heard of plans to use abandoned mine shafts and/or oil wells: pump air into the (sealed) cavern during off-peak hours, then allow the air to flow through generation turbines during peak loads.

I do like the idea applied to green power generators, eliminating the cost and maintainence of batteries.

They then sell the power back to the New England utilities the very next day when the value of the MWh is much higher. I understand that their round trip efficiciency is better than 90%.
The power being transferred is somewhere in the GW (1000MW, or 1 000 000 kW) range.

But energy storage in the potential energy of water needs quite significant quantities of water, and apart from salt water, most of the world needs it more for drinking and food production than for making light bulbs glow...

Its been around a long time, not sure if they actually use it or how effective it is ( remember it from a summer student work term a long time ago)
