Building on the success of the earlier demonstration started in 2015, Sumitomo Electric deployed a larger 51MWh Vanadium Redox Flow Battery system at the Minami-Hayakita Substation, playing a crucial role in Hokkaido Electric Power Network's initiative to integrate 162MW of new wind power capacity into the grid.
Why is vanadium a problem?
However, as the grid becomes increasingly dominated by renewables, more and more flow batteries will be needed to provide long-duration storage. Demand for vanadium will grow, and that will be a problem. “Vanadium is found around the world but in dilute amounts, and extracting it is difficult,” says Rodby.
What is the Y axis of Vanadium prices?
Vanadium prices and corresponding electrolyte prices from 1980 through 2021. The left-hand Y axis measures the market price of vanadium pentoxide, a common source of vanadium sold on the global market. The right-hand Y axis translates those prices into prices for vanadium-based electrolytes for flow batteries.
Why does Hokkaido need a storage battery system?
However, due to the limited capacity of Hokkaido's power grids, the region faced challenges in controlling the variable output of renewable generation. To address this issue, HEPCO introduced a large-scale storage battery system at the Minami-Hayakita Substation.
Why do energy storage devices need to be able to store electricity?
And because there can be hours and even days with no wind, for example, some energy storage devices must be able to store a large amount of electricity for a long time.
