Storage: The Best Renewable Energy Integration Strategy?

Don't count out the vanadium redox battery (VRB). VRB Power is out of business but the technology was picked up by a larger company with deeper pockets - which any emerging technology absolutely needs. Utility-Savings for more details. So you can recommend the technology again.

Regarding "cheap" storage media, don't forget the poor round-trip efficiency of molten salt and the true costs of trying to site pumped hydro and CAES. Environmental concerns and the very specific locational requirements make pumped hydro and CAES very iffy. And include the round trip efficiency of CAES - including the need to burn natural gas - and distributed advanced batteries like NAS and VRB make sense. The price will come down with economies of scale.
