As learned from EnergyTrend，CATL held its 2026 new energy storage product launch event in Munich, Germany on June 22, officially unveiling the TENER Sodium-ion Energy Storage System (CATL TENER Sodium).
CATL disclosed that deliveries of the TENER Sodium-ion Energy Storage System will kick off in the Chinese market in September 2026, with full-year shipments projected to hit 1 GWh for 2026. Global deliveries are scheduled to commence in June 2027.
Built on CATL’s exclusive platform engineered for sodium-ion batteries, the TENER Sodium system caters to diverse energy storage duration requirements ranging from 1-hour, 2-hour, 4-hour, 6-hour to 8-hour applications. Each cabinet of the system weighs less than 42 tons, and a 1 GWh energy storage facility can be assembled with merely 34 units.
Industry insiders widely agree that the release of concrete mass delivery timelines and volume targets marks CATL’s official entry into the GWh-scale commercialization phase for sodium-ion energy storage.
Prior to this launch, around the SNEC exhibition in Shanghai earlier this year, CATL had already shared core specifications and mass production roadmaps for its sodium-ion energy storage system. However, the official announcement of the product’s official name and full suite of system innovations took place exclusively at this Munich launch in Germany.
On May 17, CATL inked a 60 GWh strategic cooperation agreement for sodium-ion battery energy storage with HyperStrong. To date, this stands as the world’s largest single sodium energy storage order by capacity.
Driven by advancing sodium-ion technologies and completed production capacity preparations, numerous energy storage enterprises have acquired the capability for large-scale sodium-ion manufacturing. As the energy storage market embarks on sodium-ion adoption, competition among leading manufacturers has intensified.
Taking CATL as an example, its dedicated sodium-ion production line at the Fuding manufacturing base has been successfully commissioned with full mass-production capacity. At present, major industry players are accelerating mass production, product deliveries and real-world deployment of sodium-ion energy storage solutions, aligned with their proprietary technical routes and capacity plans. The sector is gradually evolving into a landscape featuring differentiated competition.
