The whole article is misleading. Hydro and geothermal are the only mentioned "flexible" substitutes for storage because this is a hit piece written by the old guard. "Flexible" is code for coal and gas plants that are currently fired up on demand already. C'mon now, use a little critical thinking and some follow the money. There isn't enough hydro and geothermal installed base to handle the load of the night time / non-windy day use cases.
