Energy Center™
Scalable MWh or GWh energy storage for utility, IPP, and commercial customers
Unlimited cycling with no capacity degradation
ESS Tech, Inc.’s (ESS’) patented electrode design and control system allow the Energy Center to operate at high efficiency over an unlimited number of deep charge and discharge cycles with no degradation or capacity fade.
Flexible, modular design created for utility-scale applications
The Energy Center units can be configured to deliver customized power and discharge durations, maximizing project flexibility, and delivering the lowest operational cost to owners.
25-year operating design life
ESS products are engineered for a 25-year design life with minimal annual operations & maintenance (O&M) requirements.
Easy deployment and operation
The Energy Center’s benign iron electrochemistry make it safe and easy to permit and site. The environmentally-friendly chemistry also enables standard, lower cost components for construction.
ESS Energy Center beyond six hours
ESS has worked closely with leading engineering firms to deliver a design-build approach that enables systems to be tailored to meet any project size with a configurable range of power and energy capacities starting at 145 kW DC for 8 hours with capability to offer extended energy durations. The Energy Center can also be upgraded by adding electrolyte to increase energy capacity and discharge duration, maximizing project flexibility and delivering the lowest operational costs to owners.
Long-duration iron flow battery
Our cutting-edge technology offers up to 8 hours of continuous discharge at rated power, making it a reliable solution for utility-scale applications. With a flexible and modular design, our batteries can be tailored to meet specific energy storage needs. Rest assured, our batteries are engineered to eliminate the risk of thermal runaway and meet the highest safety standards with an IEEE-693 Seismic High rating, NFPA 855 certification, and compliance with the California Fire Code CIFC 1207.
Our batteries are designed for longevity, boasting a 25-year lifespan. They are not only safe and sustainable but also guarantee consistent power and energy output regardless of the duty cycle. With low operation and maintenance costs, our batteries offer cost-effective energy storage solutions. Additionally, our streamlined permitting process ensures a hassle-free installation with no hidden liabilities, thanks to our simplified hazmat compliance plan requirements.
Easy to site, install and operate
The Energy Center’s environmentally benign chemistry – comprised of iron, salt and water – make this solution one of the easiest to deploy and maintain.
- Easy to site and permit.
- No risk of thermal runaway delivers safe, reliable operation.
- Standard components enable service and repair.
- Safe operations and low O&M cost.
Flexible, configurable and upgradable
Energy systems and markets are evolving rapidly. The ESS Energy Center is designed with flexibility in mind to adjust to changing needs over the 25-year operating design life.
Power (rate of electricity flow) and capacity (total amount of energy stored) operate independently, providing the flexibility to serve multiple use cases simultaneously. When it’s time to upgrade, simply add electrolyte to increase energy capacity and discharge duration.
Supports environmental, social, governance (ESG) goals
ESS technology is safe and sustainable with the lowest lifecycle carbon footprint of any storage technology available today and enabling the use of clean, renewable energy 24/7.
