Dense means they have a good size to kw/h ratio. If it's too low, nobody will install them. Space is a premium after all.

  Space in the cities is premium. Space in rural areas is not. I really don't think space is the problem, mass producing maybe, but otherwise have a big powerbank in every basement and you are done.

    > have a big powerbank in every basement and you are done. Especially in the case of flooding, Fukushima style.

      Flooding destroys alsl batteries obviously, but the slightly important difference to Fukoshima is, a saltwater batterie does not contaminate the area.

      Besides that most areas aren't in the risk of flooding, there is litte preventing you to water proof your batteries to the point that submerging them into water has no ill effects. The housing of the batteries usually is water-proof anyway. Just look at all the Teslas driving through deep water. Oil tanks for heating are a huge problem with flooding though, as they tend to leak oil into the environment.

    This is right. For grid connected storage, two things matter: 10-year total cost, and durability. At least a 30-year design life. (Well, reliability matters too: that 's implicit.) Volume and mass are just whatever they are. They don't matter.
