CATL and Intilion Target 3 GWh Sodium-Ion Storage in Europe
CATL and Intilion have signed an agreement to develop up to 3 GWh of sodium-ion battery storage projects in German-speaking Europe over the next five years. This collaboration expands their existing partnership into sodium-ion technology. CATL's technology offers high efficiency and long cycle life, with benefits for environmental impact and noise emissions.
A collaboration has been formed between Chinese battery manufacturer CATL and German energy storage system integrator Intilion, aimed at the joint development of sodium-ion battery energy storage projects with a capacity of up to 3 GWh. These projects are slated for German-speaking Europe, specifically the DACH region (Germany, Austria, and Switzerland), over the next five years.
The announcement was made by Intilion CEO Hubertus Jakobi on October 9, marking an expansion of their established cooperation to include an additional battery chemistry. Intilion, a company based in Paderborn and part of Germany's HOPPECKE Group, specializes in integrating battery technologies into utility-scale, commercial, and industrial storage systems, offering services such as engineering, software, commissioning, and maintenance.
The 3 GWh figure represents a development target. CATL's sodium-ion technology, such as the TENER Sodium energy storage system, boasts a round-trip efficiency exceeding 96.5% and a lifespan of over 15,000 charge-discharge cycles. Capacity retention remains above 90% at low temperatures, with TENER Sodium specifications indicating over 92% retention at -20 C. The modular TENER Sodium system, unveiled in June 2026, offers more than 30 MWh per standardized energy block and supports storage durations ranging from one to eight hours.
Jakobi highlighted the advantages of sodium-ion technology, including reduced environmental impacts associated with raw material extraction and lower noise emissions at storage sites. This partnership follows other European sodium-ion collaborations, including one with Dutch energy technology supplier Alfen for 5 GWh and a 60 GWh agreement with Chinese integrator HyperStrong. CATL anticipates shipping 1 GWh of sodium-ion storage in 2026, with international deliveries scheduled to commence in June 2027. This agreement strengthens both companies' positions in the European energy storage market.
