24GW / 35.8M registered UK vehicles (June 2014)

= 670W

670W/12V = 55A

I'm going to say that the average capacity of a 12V automotive starter battery is 55Ah. So there is a sufficient number of car batteries out there to power your 24GW for an hour.

I'm not suggesting this as a practical solution but people seem to think it it ludicrously far fetched to imagine manufacturing vast quantities of batteries to provide grid scale storage but no-one blinks an eye that there are at least 35 Million car batteries sitting around out there.  Imagine how impossible it would have seemed once that we would have the resources to manufacture hundreds of millions of precision engineered internal combustion engines or even dig enough asphalt and gravel out of the sand to build a worldwide network of paved roads.
