We started with a radical idea. Shouldn’t energy storage be safe, highly scalable, long-lasting and economical at the same time? That’s why we developed an advanced flow battery and energy storages based on it. Integrated with the power grid, our energy storages make it ready for the maximum renewable penetration with the minimum fossil-fueled power plants.


We’re on a mission to help generation companies and grid operators do their jobs without sacrificing environment-friendliness and economy.
