What are ESS Iron Flow batteries?

ESS iron flow batteries ensure electricity is available when it’s needed despite aging infrastructure, climate impacts, remote locations, or fluctuations in supply and demand. Mitigate renewable intermittency and eliminate the need for fossil fuel plants with up to 12 hours of storage. ESS batteries are the foundation for a decarbonized grid.

What are ESS batteries?

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.

How are ESS batteries made?

ESS’s long-duration batteries are manufactured using iron, salt and water, and offer customers, safe, low-cost and sustainable energy storage.

What is ESS Iron Flow Technology?

Using easy-to-source iron, salt, and water, ESS iron flow technology enables energy security, reliability and resilience. We build flexible storage solutions that allow our customers to meet increasing energy demand without power disruptions and maximize the value potential of excess renewable energy.

Why should you choose ESS batteries?

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.

What is ESS iron flow chemistry?

ESS has developed, tested, validated, and commercialized iron flow technology since 2011. While conventional battery chemistries deliver a 7- to 10-year lifecycle before requiring augmentation, ESS iron flow chemistry delivers 25+ years and unlimited cycling with no capacity fade or degradation.
