La empresa ha compartido con pv magazine que prevé iniciar durante el verano de 2026 sus primeros proyectos piloto tanto de celdas como de sistemas de almacenamiento completos.
Why it matters: Stop waiting for a 'lithium killer' to lower your equipment costs; domestic sodium-ion won't hit the channel at scale until your current project warranties are halfway through their life.
Let’s address the 2028 elephant in the room. While Bihar Batteries aiming for a sodium-ion (Na-ion) pilot line in the Basque Country is a win for European strategic autonomy, a four-year lead time in the battery world is roughly equivalent to a century. By the time those first Spanish cells roll off the line, the LFP (Lithium Iron Phosphate) market—currently being crushed by Chinese overcapacity—will have likely hit price floors we can't even imagine today.
The Practical Limits of the Sodium Swap
For a solar developer in Germany or a residential installer in the Netherlands, Na-ion is the "promise of tomorrow" that keeps getting pushed back. The technical upside is undeniable: better performance in sub-zero temperatures and zero reliance on the volatile lithium-cobalt-nickel triad. However, the market signal here is mixed. CATL and HiNa are already putting Na-ion into small EVs and stationary packs in Asia. A European pilot starting its journey in 2027 risks being a boutique solution for government-mandated "Made in EU" projects rather than a competitive alternative for cost-sensitive commercial proposals.
Bottom line: We’ve seen these manufacturing roadmaps before. Until you can actually order a pallet of these for a project in Seville or Berlin, treat sodium-ion as a fascinating hedge against future lithium spikes, not a current procurement strategy.
