It's a cool idea, but unfortunately their brochure has no details. It's just there to get you to fill out the contact form.

One of the few numbers I could find on their site was:

> Our standard frame 200MWh battery requires about 5 he (12 acres) of land to be built.

They also refer to it as a "20MW/200MWh" plant.

That is a rather large amount of land, which more concerningly to me means a huge amount of equipment to get to that 200MWh, which would hint at very very high cost. I wonder how cheap they can get it.
