Long-Duration
Energy Storage That's Safe
Accelerates Renewables
Long-duration storage is critical to grow renewable energy above 25% grid utilization. ESS solutions, available now, enable increased renewables penetration.
Stabilizes the Grid
Flexible capacity enables the time shifting of intermittent renewables from supply peaks to demand peaks, balancing load and transforming the grid.
Enables Distributed Generation
Distributed generation using microgrids and VPPs is fundamental to a cleaner, safer, and more resilient grid. Long-duration storage deployed globally enables this.
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 4-12 hours of storage.
Optimal Performance
Fast response time, unlimited cycle life and no capacity degradation over a 25-year operating life delivers operational flexibility.
Environmentally Sustainable
ESS batteries are safe, water-based, non-hazardous, and fully recyclable. Use of abundant resources ensures sustainable production too.
