Long-Duration
Energy Storage That's Safe
ESS Inc. News
Accelerates Renewables
Long-duration storage is critical to create a decarbonized grid powered by renewable energy. ESS solutions, available now, enable the growing penetration of renewables and can deliver clean energy 24/7.
Stabilizes the Grid
Flexible capacity enables the time shifting of intermittent renewables from supply peaks to demand peaks, balancing load and transforming the grid.
Iron Flow Batteries
The right technology at the right time

Lowest Cost (LCOS)
By combining easy-to-scale technology with low-cost chemistry, ESS delivers the lowest cost across 6-12 hours of storage.
Optimal Performance
Fast response time, unlimited cycle life and no capacity degradation over a 25-year design life delivers operational flexibility.
Environmentally Sustainable
ESS batteries are safe, water-based, non-hazardous, fully recyclable and have a low carbon footprint. Use of earth-abundant resources ensures sustainable production too.
