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

    Energy densities

    Edit: Looks like their gravimetric energy density is 3.5kWh/kg

    Edit 2: here’s a comparison for batteries

      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.
