Since it’s solid hydrogen I think it’s to be expected, however I didn’t see any information regarding energy losses which I imagine would be quite high when you have those kinds of cooling requirements.
This is why I hate marketing pushes. If they’re a good-faith business, the efficiency needs to be within shooting distance of reasonable against costs. But as we learned from the artificial meat industry (that ultimately admitted we’ve already probably reached lifetime price/quality/scale limits from the methodologies they’re using) brutal honesty doesn’t get you investors.
According to their site:
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.
Edit: Looks like their gravimetric energy density is 3.5kWh/kg
Edit 2: here’s a comparison for batteries

Thats in the ballpark of a year of usage from a household. Neat if true.
