"Exploring the use of Iron" "Limited by Nickel" "Limited by Nickel": This is just lithium ion battery storage, it is plainly obvious. "Exploring the use of Iron": using LFP (which will be 200-230 wh/kg in production later this year) "Added some sulphur": great, but you're wayyyy behind the current state of the art research in Li-S. That cost is appropriate for maybe a day or two of storage. Months between seasons? That's ridiculous, even if we had a dirt-cheap 200 wh/kg sodium ion battery which COULD probably hit 6$/kg, unlike their unnamed/unspecified techs they are "looking into". Likely it is since every other battery buzzword was notched in this article. The use case, providing more energy in the summer, is covered with solar + couple day grid storage and existing nuclear or gas turbine for load leveling. What we need is to install as much wind and solar as possible to immediately eliminate coal, then add storage and more wind/solar as needed to start eating away at gas turbine. Nuclear should stick around for long-term load levelling until batteries become dirt dirt dirt cheap. This article is so poorly written that it might as well be unintentional FUD.
