Pumped energy transfer station

It can be interesting (ecologically speaking and financially); if you lift the water with a wind turbine.

to see, maybe exploiting the energy of this wind turbine would be more profitable (strictly financially)

I allow myself a quote:

Photovoltaic solar energy can also provide solutions in terms of water pumping. Indeed our company installs in sites where the EDF network does not exist, water pumping systems, either over the sun, or in battery storage. Photovoltaics offer a real energy alternative,

It is a (very) small company.

Why not just parallel a turbine to generate current and a ram pump.
You need power, you run the generator.
You do not need it, you go up a part with the minimum of econological cost ...

trufou said that he had available 2 water reservoirs, with 10 m of elevation, with a capacity of 1000 m3.
He did not say that a major watercourse passed through there ...
If it were, it would not need to go up the descended water, with a turbine running on EDF electricity. He would have put a turbine on the passage of the descending water.
So no "ram pump".
Because a ram needs the passage of a lot of lost water (for engine operation), to bring up a little useful water.
So goes the reality of things.

For my part, I am already against the principle of its application. In addition, it would surprise me if its installation is energy efficient so that it is feasible: because of the losses.
Only thing to do: use the difference in level to make only electricity.

I have a question: how do your two tanks fill up ?! Because if the one upstream fills up naturally, then you have to explain to me why you want to raise your water from the bottom to the top. Let it rain, my boy! It will be much more ecological and much more economical for you: hence ecological !!

Now it will be up to you to manage your body of water. Eh yes!! There is no economy in overconsumption, but only in its good management. Overconsumption to try to fuck those who allow you to live today is not necessarily the panacea for all your ills.
Respect is also a way to live well, in harmony with oneself, but also with others !!

hello, sorry for my delay, but the computer was crashed , aaaaah progress!
there is interest in my email .... thank you very much
indeed I have 2 hill reservoirs, which fill only with the flow of winter water
I have heard of this method of storing energy by emptying and filling artificial reservoirs: its name is:
"pumped energy transfer station" and it is necessary to use a
"reversible turbine pump unit"
this method is used by edf and in many other countries. (see various website)
its efficiency is around 70 / 100. and it is true that we use energy to produce other energy, but edf does it itself. however, we produce by this system more clean energy than we consume maybe in my case it is not profitable but it is an idea like any other, and I lack information to know it
here is my idea, but I'm not sure it suits you
please
