Exactly. Sentences like "COULD store rather a lot of energy." are simple 
hand-wavey nonsense,.

The UK to be fully 'renewable' for example would need to store the sort 
of energy  found in half a dozen medium sized strategic nuclear bombs.

However you do that, its damned risky - hydrogen - spinning flywheels - 
hydro dams, batteries.

In fact the safest  energy store capable of doing it is a set of 
uranium/plutonium fuel rods. And then you don't need any renewable shit 
at all.

Simples!

their spears on the ground and talk of honor. Those who leap high the 
battle dance and dream of glory … The good of dead warriors, Mother, is 
that they are dead.
