CATL Launches TENER Sodium: A Groundbreaking Sodium-Ion Energy Storage Solution

On June 22, 2026, in Munich, Germany, CATL officially introduced its innovative energy storage system, TENER Sodium. This revolutionary sodium-ion solution stands out as the world's first energy storage system validated in real-world conditions, ushering in a new era of sodium-based energy storage technologies. CATL’s commitment to advancing global energy independence through sustainable and economically viable energy solutions is embodied in this launch.

Achieving Commercial Viability

The TENER Sodium system represents a significant milestone, achieving full commercial maturity across its technology, production capabilities, and supply chain readiness. CATL anticipates that cumulative shipments will reach 1 GWh by the end of 2026, with global distributions set to commence in June 2027.

William Wu, Director of CATL’s Energy Storage Technology Center, emphasized the company's mission to utilize abundant natural resources available across continents to fulfill the energy needs of the world's population, estimated at eight billion people. This approach not only advocates for the use of sodium but also introduces an additional layer of safety and longevity in battery life.

Reinventing Energy Storage

As renewable energy sources grow and the demand for electricity escalates, driven by advancements in artificial intelligence, energy storage technology is evolving from a supplementary role to a critical infrastructure element within the global power framework. Traditional lithium-based energy storage systems, however, face challenges due to limited supplies and price volatility. In contrast, sodium reserves vastly outnumber those of lithium, offering a reliable alternative that ensures enhanced performance and safety in extreme conditions.

Amanda Xu, CTO of ESS and President of ESS Europe at CATL, pointed out that the energy storage industry is moving beyond just scaling up. Today's success hinges on creating long-term value for customers. The TENER Sodium system embodies this vision, featuring a fully modular architecture with a nominal capacity of over 30 MWh. This design simplifies the deployment of projects, with each module weighing approximately 42 tons. For a 1 GWh installation, only 34 such modules are required, signifying a remarkable reduction in logistical challenges.

Advantages of Modular Architecture

CATL’s innovative platform caters explicitly to sodium-ion systems, enhancing flexibility and maintenance:

• - Easier Project Deployment: The streamlined modular concept allows for swift project rollout, minimizing installation time.
• - Flexible Configuration: Customers can adjust energy storage schedules from 1 to 8 hours based on project requirements.
• - Lower Maintenance Costs: Rapid isolation and replacement of faulty modules improve station availability while lowering operational expenses.

Groundbreaking Features

The platform for the TENER Sodium system introduces several advanced features designed for enhanced performance:
1. Voltage Regulation: Featuring a Bi-DC voltage regulation system, the TENER Sodium can automatically boost low voltage levels, enhancing the overall system's efficiency by nearly 2%. This translates to millions of additional kilowatt-hours produced annually.
2. Battery Management System (BMS): The proprietary BMS captures the unique voltage decline of sodium technology, allowing for precise tracking of charge states while also offering a 20% overcharge tolerance compared to lithium-ion batteries.
3. Reduced Auxiliary Power Consumption: The unique upper vent design drastically reduces heat production, leading to a 30% decrease in energy usage compared to traditional systems.
4. Low-Noise Operation: Maintaining a noise level of just 65 decibels permits installations near load centers, addressing community concerns typically associated with energy facilities.

Future-Proofing Energy Solutions

The adaptability of the TENER Sodium system positions it favorably amidst the volatility of lithium prices. It can co-locate sodium-ion and lithium-ion batteries without requiring alterations to existing infrastructures, offering customers significant operational flexibility.

With a decade of research backing this innovation, CATL is poised to drive the sodium-ion technology forward after investing approximately €1.2 billion in R&D since 2016. The company has accumulated over 1,600 patents, showcasing its commitment to safety, profitability, and reliability in the emerging sector of sodium-ion energy solutions.

As the energy landscape continues to evolve, CATL's TENER Sodium system signifies the convergence of sodium and lithium technologies to form a robust foundation for the future of global energy infrastructure. As TENER Sodium gears up for global deployment, its impact will resonate within the industry, advancing the transition to sustainable energy solutions worldwide.
