In the desert, there are not many.
raymon compared to the area occupied by roadblocks, I "just" wanted to point out that that of stations would be far from negligible.
As for the mountainous deserts, we have few in France ...

I do not know if we can really climb so high on rails, but saw the images .... going to divide by 3, 66000 m².

Except that we have only 70 x 4 * 734 = 205 520 tons, which is about the 1 / 4 th of the mass required for a storage capacity of 2664 MWh.
In the diagram on page 5, we see a shuttle descending "empty".
The example given by Ares probably uses 70 shuttles of 4 wagons (or 70 wagons?), But 1400 "masses" which are loaded / unloaded from the wagons.
The storage area of these masses is 1400 * 3 * 15 = 63000m²
We come back to a surface of the order of 65000 m² per station.

2 football fields;)
Attention, 15 km² = 15 000 000 m² and not 15 000 m²

Yes.
In the end, for a storage of 333x8 MWh, two stations of 65000 m² each are required.
In any case, we arrive at a density of 150 000 tonnes per occupied hectare of the same order of magnitude as a hydroelectric dam.
