San Diego Gas & Electric (SDG&E) and Sumitomo Electric (SEI) completed a zero-emissions microgrid pilot project using a vanadium redox flow (VRF) battery.
Microgrids, mini power grids that can operate independently of the larger grid and keep critical facilities powered during emergencies and power shut downs, are becoming more important in states like California that have seen a dramatic increase in wildfires, critical weather events, and other causes. Just last week about 6,000 SDG&E customers were without power due to unknown causes.
Different from more prevalent stacked lithium-ion battery cells, VRF batteries consist of tanks of liquid electrolytes and pumps that charge and discharge electrons to the grid.
Ferro-Alloy Resources Limited (LON:FAR) is developing the giant Balasausqandiq vanadium deposit in Kyzylordinskaya oblast of southern Kazakhstan. The ore at this deposit is unlike that of nearly all other primary vanadium deposits and is capable of being treated by a much lower cost process.
