The problem of using renewables is the intermittency problem. So the power grid needs to be backed up. Now there is an environmentally friendly battery that only uses salt water and iron. Unlike other types of battery, it can be recharged and never lose capacity. It can supply power for up to four hours. 2 to 4 times longer than a lithium battery.
