Google's Iron Battery Powers Minnesota Data Center
25 Feb
Summary
- A new Google data center in Minnesota will use a massive 300-megawatt battery.
- The battery utilizes Form Energy's innovative, low-cost iron-air technology.
- This project is backed by 1.9 gigawatts of clean power generation.
Google is set to launch its inaugural data center in Minnesota, located in Pine Island. This facility will operate on 1.9 gigawatts of clean energy, notably incorporating a groundbreaking 300-megawatt battery system developed by Form Energy.
The battery employs Form Energy's cost-effective iron-air technology, a departure from conventional lithium-ion. This system stores energy through the rusting and deoxidizing of iron, offering a significantly cheaper alternative despite lower efficiency. The battery is designed to deliver its rated power for an extended 100-hour duration.
This large-scale battery aims to "firm" renewable energy sources, ensuring consistent power delivery even during intermittent periods. Google's initiative also introduces a unique utility fee structure in Minnesota, designed to facilitate the adoption of clean technologies.
