How Smart EV Charging Will Help Promote Renewable Power Generation

Wallbox

The proportion of grid electricity generated by renewables such as wind and solar energy fluctuates depending on how hard the wind is blowing or how strong the sun is shining. This can lead to a huge variation in the grid power available, which can be a problem for power companies. How EVs can help balance the grid.

Harvard team demonstrates new metal-free organic–inorganic aqueous flow battery; potential breakthrough for low-cost grid-scale storage

Green Car Congress

In a paper in Nature , they suggest that the use of such redox-active organic molecules instead of redox-active metals represents a new and promising direction for realizing massive electrical energy storage at greatly reduced cost. You could theoretically put this on any node on the grid.
