You seem to be saying you think keeping liquid fuel in tanks does not qualify as storage. If that is what you mean, you will need to explain why you think that, because it makes no sense.

If you mean we have not yet built out as much storage as we will ultimately need, because we anyway haven't enough renewable generating capacity built out yet to charge it from, then yes we know. The solution to that is obviously to continue building out renewable generating capacity, and then storage for the excess.
