Kemiwatt develops an innovative technology of redox flow batteries for the world market of stationary energy storage. A typical application is the storage of renewable energy (solar, wind), either off-grid for micro/mini-grid, or for grid services (load-shifting, peak-shaving, investment deferral...).

Because they store energy in liquids, redox flow batteries can store many hours of production at their rated power and have extremely long lifetimes (10+ years).

Kemiwatt's specific chemistry, with organic molecules in non-corrosive alkaline aqueous solutions, leads to a simple, robust system, that can work steadily for years with little maintenance.
