CATL Debuts World's First Field-Validated Sodium-Ion Storage System in Munich

By TestNeeti Editorial TeamPublished Sunday, 5 July 2026 2 min readSource: Business Insider MarketsArticle 8 of 17

CATL unveiled the TENER Sodium Energy Storage System, the world's first real-world validated sodium-ion energy storage solution, in Munich, Germany, on July 5, 2026. The company said the solution has reached full commercial maturity across technology, production capacity and supply-chain readiness. Cumulative shipments are expected to reach 1 GWh by the end of 2026, with global deliveries beginning in June 2027. Sodium is over 1,000 times more abundant than lithium and offers better extreme-temperature performance, safety and cost potential. Powered by CATL's latest sodium-ion technology, TENER Sodium delivers more than 30 MWh of rated capacity on a fully modular architecture, with each module weighing about 42 tonnes and only 34 units required for a 1 GWh site. Storage durations of 1, 2, 4, 6 and 8 hours are supported.

Background & Context

Sodium-ion batteries use sodium instead of lithium as the charge carrier. Because sodium is far more abundant and widely distributed than lithium, sodium-ion chemistry promises lower cost and reduced supply-chain risk, along with better safety and performance in extreme temperatures, though it has historically offered lower energy density. Battery Energy Storage Systems (BESS) store electricity for later use and are critical for integrating variable renewable energy such as solar and wind into power grids. CATL (Contemporary Amperex Technology Co. Limited) is a leading global battery manufacturer.
