A framework agreement for the deployment of 2GWh of iron electrolyte flow batteries has been signed between manufacturer ESS Inc and SB Energy, the clean energy arm of Japanese telecoms giant Softbank.
Flow batteries have so far, failed to live up to the disruptive potential they promise, a new report says, but authors Alex Eller and William Tokash at Navigant Research have identified 12 leading vendors in the nascent field, based on metrics of strategy and execution.
ESS Inc, US maker of the only flow battery that uses a battery chemistry based on iron and saltwater electrolytes, is making its first incursion into the Brazilian energy storage market.
