Transforming the grid to be reliable, resilient, and fully renewable

The electric grid now faces a challenge: how to manage the multi-day variability of renewable energy without sacrificing reliability or cost. We are developing a multi-day energy storage technology that will enable the grid to run on low-cost renewables year-round. Our pioneering battery technology will reshape the global electric system and give it new form.

Battery Storage Technology

Our first commercial product is an iron-air battery capable of storing electricity for 100 hours at system costs competitive with legacy power plants. Made from iron, one of the most abundant minerals on Earth, this front-of-the-meter battery will enable a cost-effective, renewable energy grid year-round.


Grid Modeling Toolkit

Formware™ is our next generation investment and operational model for power grids.  It has the ability to optimize over multi-year, hourly resolution data sets to capture real-world weather variability, resulting in more reliable and cost effective designs for renewables-driven power systems.
