Under a cent for each time you store a kwh

This is present rather than future. But if the present is this cheap that means ‘Solar is great but what about storage’ arguments have an answer. And also to a large extent ‘What about climate change’.
What am I missing? Are batteries now really that cheap? I the west there will be different regulations, insurance etc. But do they really double the price of batteries? And if so is 2 cent a kilowatt hour still not cheap?
I did a notebook here taking Irish wholesale electricity prices and at this price a battery that is supposed to last 20 yeas could pay for itself in 2 yeas or less [https://colab.research.google.com/drive/18GBsxsUkDPJQ_N9dgwgIxi3qTPo6YfTb?usp=sharing](https://colab.research.google.com/drive/18GBsxsUkDPJQ_N9dgwgIxi3qTPo6YfTb?usp=sharing)
Then again it’s China…
Plus it’s still not a sustainable solution in the long run. Current battery tech relies on non-renewable raw materials like lithium. Not to mention how much land area is needed for these things.
More like a stop gap until we figure out something better.
Seems like LFP is a bit wasted here. Energy storage would be a prime use case for Sodium batteries. Much cheaper to produce.
