Form Energy
Developer of iron-air batteries for ultra-long-duration (100+ hour) grid energy storage, aimed at multi-day backup power rather than the 2-4 hour discharge window of conventional lithium-ion systems. Form Energy signed a landmark agreement with Meta in April 2026 reserving up to 1 gigawatt (100 gigawatt-hours) of its iron-air storage capacity to help power Meta's data center networks, as AI data center operators increasingly turn to battery energy storage systems (BESS) to manage power surges and grid resilience amid multi-year utility interconnection wait times.
