Google has announced its support for a large-scale 30 GWh iron-air battery storage project in partnership with Form Energy, aiming to strengthen clean energy supply for its growing AI data center operations. The initiative reflects the company’s long-term commitment to carbon-free energy and sustainable infrastructure.
The project will deploy a 300 MW battery system capable of delivering long-duration energy storage of up to 100 hours. This makes it one of the largest battery storage deployments focused on ensuring continuous and reliable power for high-energy computing facilities.
Form Energy’s iron-air battery technology uses a unique process often described as reversible rusting, where iron reacts with oxygen to generate electricity and reverses the process during charging. This approach is considered more cost-effective for long-duration storage compared to conventional lithium-ion batteries.
The energy storage system is expected to help Google manage the increasing electricity demand driven by artificial intelligence, cloud computing, and data processing infrastructure. Long-duration storage is becoming critical as tech companies seek uninterrupted renewable power.
This partnership also highlights the growing role of advanced battery technologies in supporting renewable energy integration. Large storage systems like these can help balance power grids by storing excess renewable energy and supplying it when needed.
With this development, Google continues to expand its clean energy investments while supporting next-generation battery innovation. The project also demonstrates how energy storage will play a key role in powering future AI-driven digital infrastructure.
