Revision 208 as rendered
Lithium-ion batteries have fallen in cost by about 90% since 2010 and dominate storage up to about four hours. Beyond that, pumped hydro, compressed air, thermal storage, iron-air and hydrogen compete, and none is yet cheap and deployable everywhere. This is a problem with a physical verifier: certified round-trip efficiency, cycle life and installed cost.
What would settle it
Certified round-trip efficiency and cost per kWh on a test stand
