Could the Next Generation of Batteries Be Based on Iron and Not Lithium?
ESS Inc., a ten-year-old, Oregon-based company has developed a low-cost, iron-flow battery for long-duration energy backup requirements of up to 12 hours per battery pack. Iron-flow batteries combine iron, salt, and a water-based electrolyte to produce reliable electricity storage suitable for utilities and industrial sites where flexible energy capacity is needed.
The battery's four components include two electrodes, the electrolyte and a separator. A pump keeps the electrolyte flowing as charged particles shuffle between the electrodes while the separator prevents a short circuit. Each battery comes packed into a shipping container. These can be daisy-chained to other containers to rapidly expand energy storage for any site. That's why you can see the efficacy of use for utility and large industrial and commercial operations.
Could the Next Generation of Batteries Be Based on Iron and Not Lithium?
ESS has perfected a flow battery that uses water as its electrolyte and can operate as a 12-hour battery backup to solar or wind.
