Key Points:
- Google is building its first data center in Minnesota, located in Pine Island, powered by 1.9 gigawatts of clean energy including a 300-megawatt iron-air battery from startup Form Energy.
- The project involves 1.4 gigawatts of wind power and 200 megawatts of solar power in partnership with Xcel Energy, with the battery capable of delivering power for 100 hours, making it the largest battery in the world at 30 gigawatt-hours.
- Form Energy’s iron-air battery technology stores energy through rusting and deoxidizing iron, offering lower efficiency than lithium-ion but at significantly lower costs, with storage expected to cost around $20 per kilowatt-hour.
