I wonder what's the volumetric energy density, historically that has been a bigger issue than gravimetric energy density.

According to their site:

A storage system of 3 m3 can store up to 10,000 kWh of energy

So about 3.33 MWh per cubic meter, 3.33 kWh per liter, or 3.33 Wh per cubic centimeter.

Hmm, if that's correct, that's even higher than liquid hydrogen, which would be really impressive.
