My company operates two Jupiter Power owned LFP batteries in the MISO market. Each of them draws .5 - 2MW constantly for the HVAC system. If the cost for sodium batteries is similar to LFP, that alone would be a reason to switch.

I want to replace my Lithium home battery, and what I really want to do it to move to one of the new sodium ion batteries..e.g like the one CATL is supposed to have at some point?<p>Anyone have a good idea when these will be available for consumers?

Keep in mind, we could have had local Na-Ion battery production in the US. The company producing them needed about $5m of bridge loans, with products already sitting in warehouses awaiting the UL certification.<p>This company got sold for scrap.

> Peak Energy is buying its commercial cells via contracts with Chinese suppliers<p>So really just assembly and sales then. I suppose it's a good start and maybe if business takes off they can figure out their own cells.

Its a failure in the U.S. because the bet is on solid state batteries. Personally I won't take the EV plunge until they have those. The only exception for me to not wait would be the 10k BYD car. At that price point and it lasted 3 years i'd be happy.
