Overview
Form Energy develops and commercializes iron-air multi-day energy storage systems designed for roughly 100-hour duration. On August 12, 2026 the company announced a $750 million Series G led by T. Rowe Price (also Series F lead), bringing total equity raised to over $2 billion. New investors include Sequoia Capital, Janus Henderson, Franklin Templeton, and PEAK6; returning investors include Coatue, Energy Impact Partners, Breakthrough Energy Ventures, TPG Rise Climate, and GE Vernova. Proceeds fund manufacturing scale-up in Weirton, West Virginia and commercial deployments. Company-disclosed backlog grew from about 20 GWh to 80 GWh in 2026, including projects with Xcel Energy, Google, Crusoe, and FuturEnergy Ireland.
Why Form Energy is interesting
August 2026 Series G ($750M, >$2B total equity) led by T. Rowe Price with Sequoia joining and Coatue/EIP returning — capital for Weirton manufacturing and commercial deployments after backlog jumped ~20→80 GWh.
Product & use cases
Multi-day iron-air battery systems for grid-scale energy storage, optimized for long-duration firming rather than short-duration peaking.
- Utility multi-day renewable firming
- Hyperscale / industrial backup across multi-day outages or renewable lulls
- Grid reliability where gas peakers are the expensive alternative

Competitive landscape
Edge: Chemistry and product aimed at ~100-hour duration with contracted GWh backlog and a U.S. factory ramp — late-stage capital is for manufacturing and deployments, not lab R&D.
Form competes for firm multi-day capacity dollars. Winning requires offtake, interconnection, and manufacturing yield — not only cycle-life slides versus lithium.
-
Fluence / Tesla Megapack-class BESS adjacent
Lithium-ion short-to-medium duration; different procurement unit and use case.
-
Base Power adjacent
Residential virtual power plant; hours at the home edge, not multi-day utility iron-air.
-
Gas peakers incumbent
Traditional firming resource; carbon and fuel-price exposure.
