Flywheel Storage Cost: What is the Average?

[jkim6881]

I am studying renewable engineering at uni..

And found the flywheel storage interesting.

I did my own research and found out that it is expensive to implement this technique.

However, all the articles describe the cost as expensive, not with specific figure ($)

So, I wonder what is the average cost to implement this system? can you please link the site?

I found plenty of references just by searching on Google for 'flywheel cost per kwh'.

Maybe give that a try.
