alt Hacker NewsI'm not convinced we'll ever see mass deployments of batteries to homes, not because of the fossil fuel lobby but because of the economies of scale from installing grid sized batteries at strategic points in the transmission network.
In California grid scale batteries have capital costs of around $125/kWh to $155/kWh while a home battery might be 20x that including installation.

It’s already happening as I write this. An enormous amount of capital and labor are already deployed to find ways to get batteries into people’s homes, and growth is accelerating.
That's because home battery providers aren't competing on price yet. The market is still small, the risks are high and they need to figure things out.
Once the early adopters run out they will have to start competing on price to make sales. There's no justification for a home battery when they charge 10k for 10kwh as they do now - only early adopters and government subsidies getting it over the line.
IMO home batteries should be a relatively easy install in principle, it's just still in that early expensive phase.
