About ESS Tech

ESS Tech makes batteries that store electricity for businesses and utilities. Its products help companies use more renewable energy and avoid power outages. These batteries are designed for long-term, large-scale energy storage needs.

Why ESS Tech Stands Out

ESS Tech uses iron, salt, and water in its batteries, making them more recyclable than many alternatives. Its proprietary “Proton Pump” addresses technical challenges unique to iron flow batteries. The company’s modular designs allow customers to scale storage to fit different project sizes.
