ESS is betting the world is ready for a billion-dollar battery disrupter


Canary Media’s take is that ESS stands to capitalize on a few trends in the clean energy market:

  • The rapid adoption of wind and solar makes storing electricity for later use more valuable.
  • Lithium-ion batteries, the current market leader for new grid storage, have notable downsides that include fire risk, supply-chain concerns and operational limitations.
  • The Biden administration says it’s time for an American manufacturing revival and unprecedented investment in grid infrastructure.

The Iron-Flow Battery is built to withstand extreme conditionsESS is betting the world is ready for a billion-dollar battery disrupter


This ESS system running in the 115-degree heat of Nevada proves the point. No need for HVAC cooling, zero risk of fire, and no sunscreen necessary. Our long-duration iron flow batteries do just fine under extreme conditions, performing well from -5°C to +50°C (23° to 122° F).

Why a seasoned energy executive sees a bright future in long-duration energy storage from ESS

Eric Dresselhuys isn’t new to the energy space. In fact, he was creating technology that electric utilities could use to make their grids smarter before the words “smart grid” were well known. 

Dresselhuys sees great growth for long-duration storage, which he defines as energy storage technology that can take energy, most likely produced by renewable sources like wind and solar, and store it for a very long time, well beyond the understood and accepted maximum of 4 hours that lithium-ion technology is used for.
