The Tesla Powerwall is (despite it's name) NOT a wall! From the sound of things, this new supercapacitor might be. I can very reasonably imagine there being many orders of magnitude more structure vs things that hang from that structure. I also suspect there may be a slight cost difference between adding some soot to the concrete you were already planning on using vs whatever they put in a Powerwall. I guess my point is there's probably usages for both.
