While most long-term energy storage (LDES) technologies are still in their early stages, power batteries have already had significant commercial success due to their long lifespan, excellent recyclability and low fire risk.
In one of the largest developments in this area, the Sacramento Municipal Utility District (SMUD), the sixth largest community-owned electric service provider in the U.S., has partnered with iron flow battery specialist ESS Tech, Inc. to supply up to 200 batteries. MW/ 2 GWh of long-term energy storage systems for iron flow.
As the partnership closed in 2022, the project reached another milestone last week with the approval of a $10 million grant from the California Energy Commission. The funding will be used to develop an eight-hour, 3.6 MW iron flow battery project, which is expected to lay the foundation for future large-scale battery deployments and manufacturing at energy centers in Sacramento.
The project aims to demonstrate the capability and reliability of iron flow battery technology in supporting grid distribution and transmission systems as SMUD transitions to a carbon-free energy portfolio by 2030.
Founded in 2011, ESS produces iron flow batteries using commonly available materials such as iron, salt and water. The batteries are designed for applications requiring up to twelve hours of flexible energy capacity and are used in utility-scale renewable energy installations, remote solar microgrids and storage, load shifting and peak shaving of solar energy, as well as other ancillary network services.
