I had the same thought reading the article, but after some thought, I doubt it.

Grid transmission can be as low as 0.5% per 100 miles already. Batteries lose about 10% of the energy by storing it, that leaves you with needing to go at least 2000 miles in order to make up the battery loss difference, plus needing the energy to move the batteries physically.

Perhaps stretch out a flow battery with a pair of pipelines? http://en.wikipedia.org/wiki/Flow_battery

We could repurpose those oil pipelines we no longer need. :-)

Float them down a river.

True. They float plenty of coal on the rivers here in Pittsburgh
