I'm struggling to understand how this works.

Overnight the energy storage system continues to press against the water in the chamber even after all the steam has condensed, this provides water pressure to continue powering a hydroelectric generator overnight.

How can this be? Heat and pressure are proportional in a gas. If the steam is condensing, it's losing energy before it can work the turbine.

What's the advantage of using water for the turbine instead of steam?

Is this basically a compressed-air energy storage system that's using heat instead of an electric compressor?

I think so, although they also mention springs as another form of energy storage.

Woops, I assumed you were the author without even looking. I should probably direct my questions to the comments of the linked article...
