Form Energy Raises $750M for Grid Batteries
Form Energy raised $750M for multi-day grid batteries, one of the largest climate-tech financings in the recent window.
Long-duration energy storage is becoming more important as grids absorb renewables, electrification and data-centre demand.
What happened
Form Energy raised a $750M Series G. The company develops multi-day grid batteries designed to store electricity for much longer periods than typical lithium-ion systems.
The size of the round makes it one of the strongest climate-tech financing signals in the current window.
Why it matters
Grid reliability is becoming a constraint on both climate goals and AI infrastructure. Data centres need huge amounts of reliable power, while renewables need storage that can cover longer gaps in wind or solar generation.
Form Energy is attacking that infrastructure layer. Its technology is not just about cleaner electricity; it is about making a more electrified economy actually work.
The bigger picture
Climate tech and AI infrastructure are increasingly linked. The more compute the world builds, the more important power, storage and grid resilience become. Long-duration batteries sit directly inside that pressure point.
