Freen OÜ is launching its latest generation of sodium-ion battery storage systems. The Freen-BSH and Freen-BSL products are developed and produced in Estonia.
The high-voltage BSH model, and low-voltage BSL are scalable; designed for homeowners, farmers, and other commercial and industrial users; and can power off-grid systems, be combined with solar; and be used to reduce peak loads.
Freen, which sells €230 ($268)/kWh lithium-ion storage systems, said its sodium-ion batteries start at €330/kWh.
The manufacturer says the BSH product has a capacity of 10.08 kWh per module, operates at a nominal 575 V, and has a voltage range of 385 V to 760 V. Maximum discharge current is 8.75 A, according to Freen, and up to 10 modules can be connected in parallel, increasing capacity up to 100.8 kWh.

I wonder why Sodium storage is more costly than Lithium? Is this an early stage thing? Or what are the other advantages of sodium if more costly at this stage?
Prices seem a bit strange given Sodium-ion is supposed to be 10% the cost of Lithium-ion to manufacture.
