The ESS Energy Warehouse

Cleaner, Longer-Duration Storage Changes Everything

Sustainable, scalable and easily transportable energy storage is here. Using food-grade, earth-abundant elements like iron, salt, and water for the electrolyte, our innovative iron flow battery system is changing how the industry deploys energy storage. Now, companies can choose a long-duration battery solution that is not only a viable alternative to lithium-ion batteries – but also comes at a lower cost. Healthy bottom line, healthy environment. That’s what ESS is all about.
