The domestic manufacturing capabilities of US flow battery providers ESS Inc and Stryten Energy have been celebrated by senior state politicians in Oregon and Georgia respectively.
Iron-saltwater flow battery company ESS Inc looks set to deploy by far its largest project to-date, a 50MW/500MWh system at a renewables hub from German energy firm LEAG, with potential for more.
ESS Inc ended 2022 with nearly 800MWh of annual production capacity for its iron flow battery, although had a relatively poor last financial quarter with just US$15,000 in revenue.
