Regarding [1], the article quotes production costs of USD 50/MWh for renewables, and USD 100/MWh for coal (graph 3).

You/[1] is saying that with storage costs of USD 150,000 per MWh, renewables can be competitive? It doesn't compute, unless I misunderstand something.

I think that $150000 per MWh buys you a storage system you can use more than once, rather than being the cost per usage of the storage system. After a few years, the amortized cost drops below coal generation.

Just from your numbers, it sounds like it's a good deal as long as you need to (grid) store less than 1/3 of your generated/consumed energy.

There's a factor of 1000 there.

150,000$ / 3,000 charge cycles (~8.3 years) = 50$/MWh = 0.05c/kWh.

Batteries last longer than one cycle...
