Google Commits $1B to Form Energy’s 100-Hour Iron-Air Battery for Minnesota Data Center:

Google is investing roughly $1 billion in a groundbreaking long-duration battery system from startup Form Energy to power a new data center in Minnesota. The price tag was first reported by The Information.

The project will combine wind, solar, and Form Energy’s iron-air battery technology, which can continuously deliver 300 megawatts of electricity for up to 100 hours. The system functions by drawing in oxygen to rust iron inside its cells — a chemical reaction that releases electrons and generates electricity. This long-duration storage solution will help stabilize energy supply from 1.4 gigawatts of wind power and 200 megawatts of solar power connected to the facility.

Form Energy has spent years developing the technology and recently established a manufacturing facility in West Virginia to scale production. However, it had not secured a major customer until finalizing this landmark agreement with Google.

With the deal in place, CEO Mateo Jaramillo said the company is now working to raise an additional $500 million. According to PitchBook, Form Energy has raised $1.4 billion to date and is planning a public listing next year.

The partnership represents a significant step forward for long-duration energy storage, particularly as data centers seek reliable clean power solutions at scale.
