This is great to see but LFP cells are already so cheap this will likely be more of an incremental improvement than a fundamental reshaping of the economics of grid scale storage.

Average costs of a new utility scale system are around $125/kWh of which $75/kWh is equipment of which $40/kWh is the LFP cells. [1] This brings cell cost down by over 50% to $19/kWh [2] but that only reduces equipment costs by a bit over 25% and total capital costs by 17%.

Height 216mm

Apparently dimensions for the lithium cell were designed based on constraints: maritime transport weight limits (50t), 1500V max system voltage ceiling, 20-foot container (turn key system - image https://www.ess-news.com/2025/04/16/hithium-unveils-587-ah-c... ).

I assume the Sodium cells are heavier but they chose the same cell size for physical backwards compatibility.

Where have I seen this writing style before...
