ESS Inc. has received UL1973 certification for the battery modules in its utility and industrial flow battery energy storage systems.

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.

Recently announced deals and partnerships in the California and Australia markets are a taste of the future ahead, ESS Inc has claimed.

Our series of energy storage industry leader interviews at RE+ 2022 continues with iron flow battery company ESS Inc.

A flow battery supply deal will accelerate a California municipal utility’s decarbonisation while derisking that process.

Malaysia-based Reservoir Link has signed a memorandum of understanding (MOU) with an unnamed US-based ‘Iron Flow Long Duration Energy Storage provider’, while ESS Inc tells Energy-Storage.news it is ‘actively exploring’ opportunities in Reservoir Link’s markets.

Increasingly, microgrids often lean on battery storage as a key component, replacing or reducing reliance on diesel and other fossil fuels.

ESS Inc has recognised revenues for the first time since publicly listing, while closing in on a 750MWh targeted annual production capacity.

Iron flow battery company ESS Inc continues to await recognition of revenues, but has “strong confidence” in its trajectory towards profitability.

ESS Inc’s long-duration iron electrolyte flow battery energy storage solution will be deployed in a demonstration and test project in Oregon by utility company Portland General Electric.
