- aeternum 2y agoI'd argue grid scale batteries are sensitive to energy density as a second order effect. Higher energy density -> More EV demand -> Eventual increasing flow of last-generation cheap used cells that can be used in the grid.

Prices have come down to ~$50/kwh in 2025 dollars, lower than Tesla et al even hoped for. This is less than estimates I've seen for major new pumped hydro projects in 2005 dollars (when I did more formal research into energy transition), and it requires no site selection, no complex approvals, no environmental mitigation policies. Grid-scale battery projects are lighting up at scale for the first time throughout the world.
