Overview

Google is set to deploy the world's largest iron-air battery system in Pine Island, Minnesota, as part of its efforts to achieve 24/7 carbon-free energy. The 300 MW / 30 GWh multi-day storage system, developed by Form Energy, will be integrated with 1.6 GW of new renewable energy sources, including 1,400 MW of wind and 200 MW of solar. This initiative is part of a regulatory framework known as the 'Clean Energy Accelerator,' which allows Google to manage deployment costs without affecting residential energy rates.
