Grid Storage Winners Part 1: Assessing The Major Technologies

Only when all three technologies are considered do we see the full spectrum of storage requirements being met. Lithium-ion’s limitations are balanced by pumped hydro storage, just as pumped hydro storage’s challenges are balance by lithium-ion. But redox flow batteries fill up all of the gaps and more.
