Life Cycle Analysis of the ESS Inc. Iron Flow Battery
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
Further Beyond 4 Hours: Revisiting Long-Duration Storage
Key Findings in Further Beyond 4 Hours Include:
- Long-duration storage is now commonly viewed as having a delivery time of at least four hours, and the need for it is growing.
- Renewable energy self-consumption is seen as the most promising application for long-duration storage. But many other applications, from backup power to short-term operating reserves, were also cited, highlighting the potential for revenue stacking.
- The most promising technology for long-duration storage is flow batteries and the key criterion for selecting a given asset is cost, particularly the level of capital expenditure required.
Beyond 4 Hours: The Transition to a More Flexible, Valuable, Long-Duration Storage Asset
Key Findings in Beyond Four Hours Include:
- Smart storage purchasers are beginning to look beyond capital expense to more effective measures of lifetime cost and flexibility.
- Long-duration storage’s capability to seamlessly integrate energy and power applications.
- Long-duration storage’s ability to provide substantial flexibility in dealing with ever-changing regulatory and legislative landscapes, not to mention commercial volatility.

In this white paper, you’ll learn how the EW™ leads competitive technologies in low cost per kWh and unlimited deep cycles, as well as with an environmentally friendly electrolyte, 20-plus year system life, turnkey installation and fast electrical response time.
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.
