Free electricity that turns off half the time and run basically randomly for the other half? Without a battery it’s useless, and you have to pay for that battery. Treating the electric grid as a battery shouldn’t be free. It’s just in this case they found the cost of battery to be greater than the value of the electricity they’re creating.

This island uses water as a battery: https://www.youtube.com/watch?v=eG4Q4kXal_U , when there's a lot of wind spinning the wind turbines, they pump up water up a mountain, and when it's less windy they let the water fall through a hydroelectric plant...

I can't imagine that's true. Spot instances come to mind.

I keep coming back to electrowinning iron. When I search for papers it looks like people have started working on it again in the last ten years. I think it's not particularly high tech. Intermittent tolerant and scalable.
