It seems to be in line with regular LiFePO4 batteries. Wikipedia is claiming 325 Wh/L^2 for Lithium iron phosphate batteries. This seems to be more about the inverter technology, which I guess is what is different here compared to a bunch of LiFePO4 cells in a box. There's a quote in the article about the inverters allowing them to get the "best footprint in the industry", so I'm guessing they managed to get the inverters down to about 45 litres in volume (or less).
