Also sodium batteries are coming to the market at a fraction of the cost.

"We’re matching the performance of [lithium iron phosphate batteries] at roughly 30% lower total cost of ownership for the system." Mukesh Chatter, cofounder and CEO, Alsym Energy

I see this as complementary to other energy storage systems, including sodium ion batteries; each will have its own strengths and weaknesses. I expect energy storage density cost will be the critical parameter here, as this looks best suited to do diurnal storage for solar power systems near out-of-town predictable power consumers like data centers.

Maintenance of the system is my biggest question. Lot of mechanical complexity with ensuring your gas containment, compressors, turbines, etc are all up to spec. This also seems like a system where you want to install the biggest capacity containment you can afford at the onset.

All of that vs lithium/sodium where you can incrementally install batteries and let it operate without much concern. Maybe some heaters if they are installed in especially cold climates.

		Don't even really need notable heaters if you regulate your thermal vents enough.

Sodium batteries will take 15 years to overtake LFPs cost. Stop gargling on hype please.

That seems unlikely since they can use the same factories and the raw material cost is significantly lower.

		It's not panacea. Only lithium vs sodium is cheaper and they can use lower grade graphite which is just slightly cheaper (overall 30% reduction). Rest is same while it's a new manufacturing process. Meanwhile 99.99% production is focused and will be continued focused LFP.
