Will The Cost of Grid-Scale Energy Storage Drop (like a stone) . . . ?

That’s what SmartGridNews.com contends:

 

The variability of renewable energy makes it hard to keep the grid stable. We could solve that if we had large batteries. However, grid-scale energy storage rarely pencils out – it is too expensive for all but the most high-value applications.

That may be changing soon. One new battery company, EOS, claims it will soon sell batteries for $200-$250 per kilowatt hour. EOS says that figure may soon drop to $160 per kWh.
