“A comprehensive agenda to combat climate change” unveiled on Tuesday by New York governor Andrew Cuomo, includes the setting of a state-wide energy storage deployment target of 1,500MW by 2025.

US commercial and industrial (C&I) sector player Advanced Microgrid Solutions (AMS) has been selected by a water authority in California to deliver a 3MWh energy storage system at a facility processing polluted groundwater.

The CEO of Primus Power agrees that at present, lithium battery systems are more bankable than the flow battery energy storage systems of the type his company makes, but asserted that he believes this will change over time.

ESS Inc, among several companies looking to commercialise a flow battery energy storage technology, has netted US$13 million in a Series B funding round from investors that include global chemical company BASF.

German-American system integrator and technology provider Younicos has completed a two-phase operation to upgrade a lead acid energy storage system for lithium batteries, at the 36MW Notrees facility in Texas.
