Google Pioneers Clean Energy Data Center In Minnesota With Revolutionary Iron-Air Battery Technology

Google is set to radically transform Minnesota’s energy landscape with its first data center in the state. Strategically located in Pine Island, just an hour southeast of Minneapolis, the facility will be powered by an impressive 1.9 gigawatts of clean energy, including a groundbreaking 300-megawatt iron‐air battery developed by startup Form Energy.

Unprecedented Energy Infrastructure

The project, executed in collaboration with Xcel Energy, will integrate 1.4 gigawatts of wind and 200 megawatts of solar power to sustainably support operations. The centerpiece is Form Energy’s battery, engineered to deliver power at its rated capacity for 100 hours. Boasting an awe-inspiring 30 gigawatt-hours storage capacity, this will be the world’s largest battery, ensuring prolonged clean energy availability and enhancing grid stability during periods of intermittent renewable generation.

Innovative Iron-Air Battery Technology

Form Energy’s approach differs from conventional lithium-ion systems by using iron-air chemistry. The process relies on the oxidation of iron to generate electricity, while charging reverses the reaction by converting rust back into metallic iron and releasing oxygen. Although iron-air batteries operate at lower efficiency rates than lithium-ion alternatives, they offer a significant cost advantage. The company estimates storage costs at roughly $20 per kilowatt-hour, positioning the technology as a practical option for long-duration storage.

Strategic Utility And Regulatory Innovation

Google is also introducing a new utility fee structure in Minnesota designed to accelerate clean energy deployment. The model, often described as a clean transition tariff, allows utilities to adopt emerging renewable technologies while maintaining regulatory compliance and limiting cost impacts on consumers. A similar framework was previously tested in Nevada through cooperation with geothermal energy developer Fervo.

Partnerships And Future Prospects

The project includes collaboration with Great River Energy, which will deploy Form Energy’s first battery installation in Minnesota. That system is expected to store 150 megawatt-hours and deliver up to 1.5 megawatts of power to the grid over a 100-hour duration. Form Energy, which has raised approximately $1.4 billion and operates manufacturing facilities in West Virginia, is positioning itself as a key player in long-duration storage.

Google’s Minnesota data center reflects a broader shift among large technology companies toward pairing renewable generation with large-scale storage. The project aims to strengthen grid reliability while supporting long-term clean energy targets.

EU Agrees On Major Overhaul Of Financial Market Supervision

European Union finance ministers have reached agreement on a sweeping package designed to strengthen oversight of the bloc’s financial markets, in a move aimed at reducing fragmentation and improving the flow of capital across borders.

A Push To Deepen Capital Markets

The Market Integration and Supervision Package, or MISP, would grant the European Securities and Markets Authority direct supervision over major market operators that are currently regulated by national authorities. The reforms are intended to make Europe’s capital markets more integrated, more efficient and better able to channel savings into productive investment.

According to the Irish presidency, the package is meant to help savings and investments move more freely across the European Union, improving access to finance for companies while giving households broader opportunities to earn returns on their savings.

What The Reform Would Change

Under the new framework, ESMA would take direct oversight of key trading venues, clearing houses, securities settlement bodies and crypto-asset service providers. The package would also establish a permanent, independent executive board within the regulator, strengthening its institutional capacity.

Market operators would be able to opt into a new EU-wide operating framework. In parallel, the reforms would seek to make national supervision more consistent and update rules governing trading, transaction completion, investment management and the use of blockchain technology.

Why The Agreement Matters

Supporters of deeper capital markets argue that Europe has long paid a price for regulatory inconsistency. While many rules are harmonised across the bloc, differences in enforcement and supervision have contributed to a patchwork system that can make cross-border investment slower and more costly.

A more integrated framework, proponents say, could lower costs for companies seeking funding and broaden the menu of investment options available to savers and institutional investors alike.

Outstanding Questions Remain

Despite the broad agreement, some important details remain unresolved. Trading venues operated by Deutsche Börse, the company behind the Frankfurt stock exchange, may remain outside ESMA’s direct supervision.

Euronews previously reported that Germany had secured an exemption for Deutsche Börse’s domestically focused trading venues, leaving part of the system under regional supervision. The latest announcement did not clarify whether that arrangement will stand.

A Step Forward For The Savings And Investments Union

Dutch Finance Minister Eelco Heinen welcomed the deal, calling it a major advance for the Capital Markets Union and saying Europe had made more progress in 10 months than in the previous 10 years.

The agreement is an important milestone in the Savings and Investments Union, the EU’s broader effort to channel more of Europeans’ savings into investments that can support growth, innovation and competitiveness across the bloc.
