Long-Duration Energy Storage

The answer to grid instability is not a quick fix – it’s long-duration storage

The difficulties plaguing the grid that left millions of people without power in early 2021 have not gone away. In fact, the Electric Reliability Council of Texas, which manages the Texas grid, reported in July that there had already been 1,280 unplanned summer outages.

The latest ESS white paper, Grid Stability in the Age of Fire and Ice: How environmentally sustainable, long-duration energy storage is starting to firm a shaky grid, explains why our long-duration iron flow battery that uses safe, earth-abundant and recyclable materials is best positioned to drive market growth in renewables, stabilize the grid, and address climate change in the years ahead.
