Energy Storage Systems careers

At ESS, we develop products to improve the future of power. This future includes the ESS energy management system, an extremely affordable and environmentally friendly battery system that minimizes electricity expenditures while providing the facility-wide backup power needed to coast through power outages.

What’s a Flow Battery?
A flow battery is an easily rechargeable system that stores its electrolyte—the material that provides energy—as a liquid in external tanks. Unlike typical batteries that are packaged as fixed cells or modules, a flow battery allows the battery’s power (the rate of electricity flow) to be decoupled from the battery’s capacity (the total amount of energy held). As a result, users are free to tune the battery’s specifications to their specific needs.
