Storage at sea by pumped storage (STEP Maritime) of renewable electricity
Re: Storage at Sea by pumped storage (STEP) of renewable electricity
Do not forget that it is taking sand at the bottom of the sea so the artificial island will be little visible. The larger the diameter, the lower the cost and it is depreciable over 100 years.

Re: Storage at Sea by pumped storage (STEP) of renewable electricity
This is a nice project but I have a hard time figuring out how 2.3 GW wind turbine (offshore load factor 30% -35%?) Could hope to replace 2 nuclear power plants by 7 reactors in total ... of a nuclear power total of 5.5 GW (load factor 80% ... finally in Belgium currently it is much less on nuclear lol) ....
Afterwards, it is enough to multiply the wind turbines and the "holes in the sea" ...
(2 300 MW expected overall capacity in 2020) was proposed early 2013 to the Zeebrugge port committee, replacing the two nuclear power plants of the Doel Nuclear Power Plant and that of Tihange.
Afterwards, it is enough to multiply the wind turbines and the "holes in the sea" ...

Quite ... it's the same calculation as the liquid containers: the bigger it is, the less the cost of the wall needed for the stored volume is important ... the least expensive (geometrically speaking) is the sphere: ratio volume / surface optimum ... but little used because more delicate to manufacture than a cylinder ...
It remains to manage the tightness .... storms, overflows ...
As you talk about depreciation, do you have an idea of the cost of this project?

Re: Storage at Sea by pumped storage (STEP) of renewable electricity
Precisely, with the onslaught of the sea it needs to be even stronger than a classic dam, already substantial and yet installed between 2 mountains at a narrowest chosen location.
Pharaonic enterprise all the same. We already talked about it in 2013 on http://www.futura-sciences.com/magazine ... gie-44259/
If they had thought of the Pharaoh's time instead of wasting their time building these ridiculous pyramids, we might not be there
The question of storage is not really solved yet.

Re: Storage at Sea by pumped storage (STEP) of renewable electricity
Pharaonic enterprise yes but less pharaonic than a pyramid or cathedral anyway ... especially with the current mechanical and energy means ...
Except that when we built the pyramids we did not think profitability (I'm not an Egyptologist but I think not) ... the profitability of the cathedrals was probably searched a little more (but in the long term), in 2 cases the profitability was much less than any current energy investment ... and that's why these projects were made!

Not understood? They built the pyramids STEP-by-STEP, is that the analogy?

Re: Storage at Sea by pumped storage (STEP) of renewable electricity
As for the cost it must not be ruinous because many artificial islands have already been built.

and the delusional project in Dubai:

But it's not without some problems:

Uh! bin not since it does not exist ...
Well ! so it was only to keep a Pharaoh's hold on a docile and believing people who did not have social networks to inform them of their blunders
But OK ! Following human errors, there is only sand and these monuments, it remains tourism as a means of subsistence, as long as the fundamentalists do not come to disrupt this financial scheme.
