Maximize value from renewable investments

Unlike typical batteries that are packaged as fixed cells or modules, a flow battery allows the power (the rate of electricity flow) to be decoupled from the capacity (the total amount of energy held). As a result, users have the flexibility to use the battery for a variety of use cases simultaneously on a project.

Smooth wind and solar intermittency

The ESS Tech, Inc. (ESS) patented electrode design and control system allow the Energy Warehouse to operate at high efficiency over an unlimited number of deep charge and discharge cycles with no degradation or capacity fade. ESS products are engineered for a 25-year design life with minimal annual operations & maintenance (O&M) requirements.

Increase resiliency and energy security

Build a more resilient grid with energy storage and fortify the protection of critical infrastructure.

ESS Energy Warehouse: storage simplified

The Energy Warehouse delivers commercial and industrial scale energy storage without the challenges associated with other battery technologies.

The containerized, fully-integrated design of our long-duration energy storage system ensures seamless installation and operation. With the ability to provide extended storage capabilities, our solution offers unparalleled reliability and efficiency for your energy needs. Enjoy the added benefit of a black start option (DC), allowing for quick and efficient power restoration in case of emergencies. Boasting a long life of over 20,000 cycles and requiring minimal maintenance, our system guarantees longevity and cost-effectiveness.

Our solution is not only flexible and scalable but also caters to a wide range of use cases, making it a versatile and adaptable choice for any energy storage requirements. Utilizing an environmentally safe and sustainable electrolyte composed of iron, salt, and water, we prioritize eco-friendly practices without compromising on performance. Say goodbye to the need for cooling or air conditioning with our energy storage system, reducing energy consumption and operating costs. Streamline the permitting process with our ETL certified system to UL 9540 standards, ensuring a smooth and hassle-free installation experience.

Cleaner technology

Made with earth-abundant elements like iron and salt, iron-flow batteries are a far more sustainable alternative to zinc, vanadium or lithium-ion technologies.

Premier technology

ESS technology is field-tested and assessed by Munich Re, who underwrites our 10-year battery module performance warranties.

Easier installation and operation

The Energy Warehouse reduces or eliminates the need for hazmat permits for transport, HVAC, fire suppression and end of life disposal planning.

Flexibility to meet any need

Gain the flexibility to shift between charge and discharge and rate of storage as needed for efficient energy management.
