That translates to $30/kWh which I think is considerably cheaper than the (also explosive) LiSO2 batteries it would be replacing. Of course their costs today are 40x higher or $1200/kWh. They are claiming current energy densities of 1.1kWh/kg of actual built packs which seems high to me (it would imply it's 3% hydrogen by weight). If accurate that blows-away the lithium primary cells they would be replacing. They predict up to 1.8kWh/kg for larger packs.
