Battery Technology First Vanadium Flow Battery in the Gigawatt-Hour Range

Where wind and solar power are scaled up as quickly as in China, the problem of "intermittency" becomes ever greater. This means that renewable energies can unfortunately only be generated relatively intermittently. You therefore need a lot of powerful energy storage systems.

In the technical debate, the intermittency problem refers to the fact that the sun does not shine 24 hours a day, the wind sometimes dies down and renewable energies can only be generated irregularly. The aim is to solve this problem by means of variable power plants or a large number of energy storage systems. China wants to solve the problem with a niche technology, vanadium redox flow batteries, abbreviated as VRFB. Two important milestones have recently been reached in the People's Republic for this new technology, which has several advantages over energy storage systems using lithium-ion batteries.
