The Iron Redox Flow Battery (IRFB), also known as Iron Salt Battery (ISB), stores and releases energy through the electrochemical reaction of iron salt. This type of battery belongs to the class of (RFB), which are alternative solutions to (LIB) for stationary applications. The IRFB can achieve up to 70% round trip . In comparison, other long duration storage technologies such as pumped hydro energy storage pr. [pdf]
ESS batteries are the foundation for a decarbonized grid. Iron flow technology allows for unlimited cycling with zero capacity degradation over a 25-year design life. That enables stacked revenue streams. Long-duration energy storage (LDES) is the linchpin of the energy transition, and ESS batteries are purpose-built to enable decarbonization.
That enables stacked revenue streams. Long-duration energy storage (LDES) is the linchpin of the energy transition, and ESS batteries are purpose-built to enable decarbonization. As the first commercial manufacturer of iron flow battery technology, ESS is delivering safe, sustainable, and flexible LDES around the world.
Ours are the greenest, lowest lifecycle cost energy storage systems you can buy. ESS batteries are comprised of earth-abundant iron, salt and water, not hazardous chemicals or costly rare-earth metals, making them environmentally benign to produce and the easiest-to-permit storage technology in the world.
The ESS iron flow battery uses the same electrolyte on both positive and negative sides. And the proton pump maintains the state of charge and battery health. Join Eric Dresselhuys, CEO and Vince Canino, COO of ESS Inc. as they take you on a tour of the ESS factory in Wilsonville, Oregon.
Substantially recyclable or reusable at end-of-life. ESS iron flow batteries reduce the need for fire suppression equipment, secondary containment, or hazmat precautions. ESS systems are substantially recyclable at end-of-life.
In further contrast to lithium-ion, ESS’s safe and sustainable iron flow technology is capable of unlimited cycling without capacity fade over a 25-year design life, delivering significant cost savings and revenue opportunities over the system's lifetime.
