Long-Duration Energy Storage
Accelerating clean, safe, and low-cost energy storage
2020 was a hard year for everyone on the planet, and many operations, including ours, spent time shuttered and operating at significantly reduced manufacturing capacity. We spent 2020 further refining our technology platform, investing in the expansion and automation of our plant to support 2 GWh of battery module production for our Energy WarehouseTM and Energy CenterTM solutions.
Additionally, we have made improvements to our electrolyte management system that allows us to greatly increase the energy density of our batteries. This breakthrough enables us to dramatically reduce the cost of the iron-flow battery for long-duration applications behind and in front of the meter.
In 2020, we were selected for many exciting projects that address our customers’ growing needs for long-duration energy storage solutions that are cost-effective, clean and sustainable, with the smallest environmental impact.
We are hiring, our factory is ramping back to full capacity, we are shipping products again, and are ready to further scale to meet the demands of the rapidly growing long-duration energy storage market.
The ESS Inc. battery has the lowest environmental impact and the lowest LCOS
Download our summary of the Life-Cycle Analysis Study
In an independent assessment conducted at the University of California-Irvine, scientists evaluated the cradle-to-gate environmental impact of three different flow battery types. Iron-flow batteries proved to be the cleanest technology compared to batteries using vanadium and zinc. They’re also significantly less harmful to the environment over their entire life cycle compared to lithium-ion batteries.
ESS Inc. contributes to groundbreaking energy storage study
CA needs 45+ GW of long-duration storage to meet climate targets
ESS was part of a select group of CESA members to contribute to the ground-breaking Long-Duration Energy Storage for California’s Clean, Reliable Grid study demonstrating that “flow batteries have been tested to show little to no degradation over their long lifetime – up to 25 years,” and “can operate at high temperature with high round trip efficiency.” The report also highlighted that significant procurement activities for long-duration storage need to happen before 2025 to ensure that California has a sufficient pipeline of long-duration storage projects to meet future grid needs.
