Let's just assume this works as advertise, at less than 1/10th the cost of lithium-ion. And we can scale it to practically infinity. And available by 2023.

What is left missing in the big picture for 100% clean, and renewable energy? As far as I can tell, Solar and Wind has already achieved cost/Wh lowered than all other form of energy and has a decent roadmap to further drive down the cost by another 50 - 60%.

Or are there some other puzzles we dont know? Or if Iron Battery works, and this will be "it" ?

Abundant, inexpensive storage plus inexpensive renewable electricity would mean one big problem solved. There are still a lot of non-electrical sources of emissions that still need to be addressed:

- Steel production

- Ammonia production

- Organic chemicals production (polymers, lubricants, solvents...)

- Electrification of transport (world car and truck fleet is still 99% combustion powered, and these iron batteries aren't the right kind for mobile usage.)

- Synthetic fuel production for applications that can't use batteries, like rockets and trans-Atlantic passengrer flights.

- Cement production, which currently releases large amounts of CO2 from fossil combustion and from the chemical transformation of limestone.

Storage is the last big scientific puzzle for doing it completely economically, yes. Thereafter it's "just" a matter of political will.

I was under the impression, let say inclusive of Storage, if Clean and Renewable energy are one third of the cost of Coal Nuclear or Gas. Then the incentive and market force will be so great no political will could stop it?
