US startup Unigrid has begun commercial-scale international shipping of its proprietary NCO sodium ion cells, making it the first battery company outside China to export sodium ion technology at scale, according to the company.
The move was made possible by crucial transportation certifications and Unigrid’s cost-efficient foundry production model. This approach makes it possible to scale up quickly without the capital burden of building your own factory. It also eliminates the risk of starting a new greenfield facility or delaying commercialization.
The San Diego-based company announced in October 2025 that it had increased its global production capacity tenfold, to 100 MWh per year, with a target of 1 GWh by 2026. Unigrid relies on Asian production facilities for most of the production, citing that local factories are often underutilized and only operate part-time.
