Batteries can balance the inappropriate timing of green supply that but most speakers seemed to judge this to be uneconomic in most cases as yet. All the same, energy storage will eventually add value to PV and wind packages because they will be time coordinated to loads. Electrovaya promoted its "non-toxic, safe" lithium-ion battery based on a proprietary ceramic separator saying its higher price is justified where intensive use exploits the excellent cycle life (not in cars) and safety. It has bought the Evonic Daimler gigafactory in Germany. See the IDTechEx battery reports such as, Lithium-ion Batteries 2016-2026 and specifically chasing non-flammable, load-bearing and higher energy density forms: Solid-State and Polymer Batteries 2017-2027and Advanced and Post-Lithium Batteries 2016-2026.
