Form Energy has raised $750 million to expand manufacturing of batteries designed to deliver power for as long as 100 hours.

The financing comes as the company moves to supply large-scale energy storage to customers including Google and Crusoe. Form Energy said the new capital will support manufacturing expansion and delivery of its long-duration battery systems.

Storage that can operate across several days is intended for grid applications where power must be available for longer than the duration typically covered by short-term batteries. The company’s fundraising is a significant bet on demand for that category of infrastructure.

The funding and customer details were reported by TechCrunch on August 12, 2026. The report did not, in the source information available to AddisMizan, specify a timetable for the manufacturing expansion or disclose all terms of the financing.
