Introduction. A flow battery is a fully rechargeable electrical energy storage device where fluids containing the active materials are pumped through a cell, promoting reduction/oxidation on both sides of an ion-exchange membrane, resulting in an electrical potential. In a battery without bulk flow of the electrolyte, the electro-active
When the technology is scaled up, MWG expects large-scale electricity storage from wind or solar power, for multiple days, could be achieved for about $20-$25 per kilowatt-hour, compared to the $100-$175 cost for an equivalent lithium-ion battery system. Kevin Clemens is an engineering consultant who has worked on automotive and
