> - li-ion energy storage is great for same day fluctuations(storage measured in hours), less so for longer. Other energy storage tech platforms have different economic properties leading to more sensible deployments (the other end of the spectrum is making hydrogen gas via electrolyzer to then convert back via fuel cell - best for storage measured in months)

For the steel making part of this, the idea is to replace coal with hydrogen gas in the iron to steel process, so making hydrogen gas of the electricity is the actual wanted output and not just a way to store energy.
