Summary
Switzerland is building a massive redox flow battery in Laufenburg (canton of Aargau) with over 2.1 GWh storage capacity and 1.2 GW power output, comparable to the output of the Leibstadt nuclear power plant. The underground battery, being built by FlexBase, aims to address Europe's energy storage challenges by stabilizing the grid when renewable sources like solar and wind are intermittent. The project can release power in milliseconds, positioning it as a critical infrastructure piece for Europe's energy transition.

· 3 pulledFlexBase is building a giant redox flow battery project in the canton of Aargau, with plans for more than 2.1 GWh of storage and more than 1.2 GW of power output in its final form
The point is not simply to build a record-breaking battery. The bigger question is how Europe keeps the lights on when solar panels and wind turbines produce power on nature's schedule, not ours.
Switzerland's giant underground battery could reshape Europe's power grid with 1.2 GW released in milliseconds.
