Technical FAQs 4

Should flow batteries be produced locally?

7 May 2025: As Europe pushes forward with the clean energy transition, producing flow batteries locally presents a unique opportunity to build a more ethical, sustainable, and transparent energy storage value chain.

Are flow batteries the future of energy storage?

3 April 2025: Our Secretary General, Anthony Price and John Alper – VoltStorage (FBE Member) were recently interviewed on The smarter E podcast about flow batteries. They spoke about how flow batteries are key to unlocking the vast energy storage needed for tomorrow’s electric ecosystem.

What are Belgium's biggest battery storage systems?

Currently, Belgium’s two biggest battery storage systems are a 50MW/100MWh system in Wallonia from French developer Corsica Sole, and a 25MW/100MWh system in Ruien by a Nippon Koei-Aquila Clean Energy joint venture.

Can flow battery technology be used as an alternative to Li-ion?

ENGIE’s energy management system (EMS) will control the batteries as they store energy generated from the onsite solar PV for use in the evenings. Invinity said it, ENGIE and EQUANS hope to use the project to better understand how flow battery technology could be used at such sites as an alternative to Li-ion.
