They just had the first stone laying ceremony so that explains the new wave of publications on the project.

They are using a Vanadium flow battery by the company Invinity Energy Systems which is British-Canadian.

I'm a little unsure whether it's a good idea to combine this with a datacenter, I hope the datacenter bubble popping won't jeopardize the whole project.
