The discovery could lead to new low-cost, long duration energy storage systems that can write fossil energy out of the picture by capturing wind and solar power for weeks, months, or even whole seasons.
To provide full day, utility scale energy storage as more wind and solar power enter the grid, a flow battery fits the bill.
I really love that there is so much research, and the associated results flowing back, around all sorts of different approaches to batteries. Without a doubt, grid storage is now the big thing needed for variable power generation technology. Being storage, it can also be located where it is required for use.
