Flywheel storage cost??

[jkim6881]

I am studying renewable engineering at uni..

And found the flywheel storage interesting during my course.

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?

has some figures on p786. Capital cost of flywheels is US$400-800/kWh.
