A little Its a little disheartening that current Lithium-Ion battery storage is at ~$350/kWh and is only projected to hit ~$150/kWh in 2050 [0].

Either the government report you cite is overly pessimistic, or bloomberg is overly optimistic: https://about.bnef.com/blog/battery-pack-prices-fall-as-mark...

$350/kWh is still ridiculously cheap. You could build a good off-grid battery system for $7000 or so, which for many people would pay itself off in a few years.
