Form Energy has raised $750.0M in a Series G round, a substantial infusion for a company that has spent years pushing a niche but critical piece of the clean energy puzzle: multi-day storage. The funding arrives as utilities and grid operators wrestle with how to keep the lights on when wind and solar generation dip for days at a stretch.
The Massachusetts-based firm builds cost-effective batteries designed to discharge power over extended periods, a capability that sets it apart from the four-hour lithium-ion systems dominating the market. With manufacturing facilities in West Virginia, Pennsylvania, and California, the company is scaling up production to meet what it sees as growing demand for grid resilience. The round’s backers weren’t disclosed, but the size suggests confidence in a technology that has moved from pilot projects to commercial deployment.
