- Sodium-ion home battery storage is emerging as an alternative to dominant lithium-ion systems.
- UNIGRID's Na+Casa battery is being installed in Europe, with U.S. installations expected by late 2026.
- The battery offers a 25-year lifespan, matching typical rooftop solar systems.
- It eliminates thermal propagation risks for enhanced safety and operates in extreme temperatures (-40°F to 140°F).
- With 9.25 kWh capacity, it's compatible with hybrid inverters and competitively priced against lithium-ion.
- Sodium-ion advantages include abundant materials, lower cost, and avoidance of critical mineral supply chains.
- UNIGRID plans to scale production from 200 MWh/year to 2 GWh/year by 2027 via Asian partnerships.
- Sodium-ion suits stationary storage due to lower energy density, making it less ideal for EVs.
