That's a weird article. It simultaneously argues that between batteries and snowy 2 there is no clear winner, that snowy 2 is a white elephant and that:
>Hornsdale Power Reserve: $690 per kilowatt-hour of storage capacity. If Snowy Hydro 2 comes in at $10 billion, its cost per kilowatt of power will be $5,000, which is 5.6 times more than Hornsdale. But its cost per kilowatt-hour of storage capacity is much lower no matter if you think $20, $29, or $250 is appropriate.
In other words in terms of storing a large volume of energy, cheaply, at high efficiency, pumped storage blows everything else out of the metaphorical water - between 3x and 34.5x cheaper!
I would say that batteries and large scale pumped storage complement each other. I don't agree that Australia will regret building it.
