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.

Energy in the Faroe Islands is produced primarily from imported fossil fuels, with further contributions from hydro and wind power. Oil products are the main energy source, mainly consumed by fishing vessels and sea transport. Electricity is produced by , and , mainly by , which is owned by all the municipalities of the Faroe Islands. The are not connected by power lines with continental Europe, and thus the archipelago can. [pdf]
In the Faroe Islands, energy is produced primarily from hydro and wind power, with oil products being the main energy source. Mostly consumed by fishing vessels and sea transport.
A number of researchers have studied the conversion of the Faroe Islands’ energy system to renewable sources. These studies looked at a single island or more broadly [ 51, 53] and their primary focus was on the techno-economic optimization of the new system.
The Faroe Islands cannot import or export electricity since they are not connected by power lines with continental Europe. Per capita annual consumption of primary energy in the Faroe Islands was 67 MWh in 2011, almost 60% above the comparable consumption in continental Denmark.
“The energy system in the Faroe Islands is an impressive example of how all available energy resources can be integrated into a smart and innovative microgrid,” says Vehkakoski.
Did you know that the Faroe Islands is one of the world’s leading nations in producing sustainable electricity with over 50% of the nation’s electricity deriving from renewable energy sources? There is no shortage of renewable power in the Faroe Islands, due to the ocean currents and tides of the Northeast Atlantic and an abundance of strong wind.
In the case of the Faroe Islands, offshore wind power was not directly evaluated for development preference . However, in narrative analysis offshore technologies were suggested to be preferable to onshore technologies.
