Long-Duration
Energy Storage That's Safe
ESS Tech, Inc. (ESS) News
Enable resilient, reliable energy today
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.
Make renewable baseload energy possible
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.
Maximize value with flexible storage
Iron flow technology allows for unlimited cycling with zero capacity degradation over a 25-year design life. That enables stacked revenue streams.
Iron flow batteries
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.
