FlexBase to Launch Europe's Largest Redox Flow Battery in Switzerland by 2029
FlexBase is developing a redox flow battery facility in Laufenburg, Switzerland, aiming for a 2.1 GWh capacity by 2029. This initiative addresses the challenge of renewable energy surplus, enabling storage and distribution when demand peaks, essential for stabilizing both Swiss and European energy grids.
FlexBase is constructing a technological center in Laufenburg, Switzerland, featuring a redox flow battery projected to have a capacity exceeding 2.1 GWh. This capacity could support approximately 210,000 households for 24 hours, contingent on performance validation.
The project involves a 27-meter deep excavation across over 40,000 m², incorporating offices, laboratories, and an AI data center. The battery uses a non-flammable, non-explosive electrolyte consisting of about 75% water.
Planned operational dates are from 2025 to 2028, with commissioning set for 2029, creating around 300 jobs. This facility aims to manage the discrepancies between renewable energy production and demand, contributing to the European energy storage landscape, which includes 2,356 projects with a total of 97.26 GW expected by 2030.
