Fun fact, that is why PR uses 160 Wh/Kg as its current "best in class". The Northvolt release is a bit cagey on what they actually have today for sale but it seems like they are going into production so that is a good thing. "Whole house" energy store (think PowerWall types of products) are getting good traction and grid scale batteries have changed some folks minds about what is "good enough" (you don't care if it is maximally dense if you can spread it out over an acre or three). So I would expect them to push for this sort of application first. The current market need for large local battery store for EV chargers is apparently one of the limiting factors in deploying new chargers, delivering spot excess demand can be provided by either onsite diesel generators (like some rest areas in California are doing now) or a battery bank. The latter is preferable for energy efficiency and maintenance reasons.
