I’ve seen a couple of videos about the relative strengths and weaknesses of different battery technologies but don’t know anything about flow batteries. Mostly interested in whether sodium-ion would be better than flow batteries for grid storage. That video claims sodium-ion batteries are projected to have $52/kWh production cost in 2025 based on various industry projections (timestamp 30:47) with a speculative $40/kWh in 2030.
Are you saying sodium-ion won’t replace lithium-ion even for grid storage, and why?
Those projected numbers seem to just be made up, extrapolated from graphs and hopes by consultants rather than based on proper techno-economic analysis.
I don’t expect Na-ion to be cheaper than Li-ion. The disadvantages seem to outweigh lower material costs.
