So Aquion makes saltwater hybrid batteries for residential and larger applications, but their 2.2 - 25kWh batteries retails for something like $420-520/kWh. Well today they claim they can get down to $200/kWh wholesale in as little as 2 years. Pretty sick to think about a 26kWh maintenance-free home battery for a little over $5k in the very near future. Logic dictates that these will quickly then fall to $100/kWh or less. What the hell happens then? Stringing together three 10kWh versions of this(redundancy) for $3k and you can easily go off grid for good in sunnier parts of the world. Aquion cuts cost reduction target by eight years At what point will Tesla Energy expand into similar battery chemistries that may be more suitable for residential applications? I'd love to see what Elon could do to the price of this kind of stationary battery tech.
