Cost-effective, multi-day energy storage systems that will enable a reliable and fully-renewable electric grid.

The Tough Tech problem we are solving

Renewable energy has reached cost parity with fossil fuels, yet solar and wind falter without sun or wind, exposing grids to weather extremes, outages, and surging demand from electrification and AI. Lithium-ion batteries, despite dramatic price drops, remain too costly for multi-day storage, blocking renewables from becoming the reliable backbone of a secure, affordable energy future.

About our solution

Form Energy delivers cost-effective iron-air batteries that store clean power for 100 hours, transforming grid reliability during prolonged stress. Made from abundant, safe materials like low-cost iron, water, and air, our multi-day storage unlocks renewables' full potential, ensuring a secure, resilient electric grid for a decarbonized world.
