The 'FlexBase' project aims to stabilize the Swiss and European grids by storing renewable energy. A Swiss firm is constructing the world's most powerful redox-flow battery in Laufenburg, Aargau. The battery installation is housed in a 27-metre-deep pit, longer than two football.
Self-contained and incredibly easy to deploy, they use proven vanadium redox flow technology to store energy in an aqueous solution that never degrades, even under continuous maximum power and depth of discharge cycling. Our technology is non-flammable, and requires little.
At the heart of this landmark project is a hybrid energy storage system integrating vanadium flow batteries (VFBs) with lithium iron phosphate (LFP) batteries-demonstrating the growing strategic importance of vanadium flow battery technology in large-scale, grid-support applications.
Unlike conventional batteries storing energy in solid electrodes, vanadium redox flow batteries use liquid electrolytes separated by membranes. This unique architecture enables: Australian households using these systems report 92% round-trip efficiency - crucial for maximizing solar.
CoolTec provides a comprehensive thermal management solution for the Netherlands 2MWh energy storage system, featuring a 20kW high-capacity liquid cooling unit combined with a 1. 5kW HVAC piping system, successfully addressing Europe's stringent climate conditions and grid.
Regulatory compliance: Building codes and standards, such as NFPA 855, reference UL 9540 as the system-level requirement. Market access: Without UL 1973, a system cannot be sold into many markets in North America.
