Pioneering 2GWh Long-Life Sodium-Ion Storage: CATL and Solarpro Partner for Central and Eastern Europe

August 9, 2026

CEEnergynews Central and Eastern Europe

Overview

CATL and Solarpro have announced a strategic agreement to deploy a pioneering 2 Gigawatt-hour (GWh) sodium-ion battery storage system across Central and Eastern Europe (CEE). Leveraging CATL’s long-lifecycle TENER Sodium system, which promises an exceptional 15,000 cycles or 25-30 years of operation, this marks the CEE region’s first large-scale sodium-ion deployment. The initiative is set to significantly enhance regional energy security and accelerate decarbonization efforts.

In Depth

Background

The Central and Eastern European (CEE) region is rapidly advancing its renewable energy transition to fulfill EU decarbonization commitments and bolster energy independence. However, the escalating integration of intermittent solar and wind power introduces substantial challenges in maintaining grid stability and ensuring a consistent, reliable energy supply. Sodium-ion batteries emerge as a compelling alternative to lithium-ion, offering several distinct advantages: lower material costs due to abundant sodium resources, enhanced safety profiles, and superior performance across a wide temperature range, including low-temperature conditions. These attributes position sodium-ion technology as exceptionally promising for the stationary energy storage market. This strategic partnership between CATL and Solarpro is therefore crucial for accelerating renewable energy integration within the CEE region and diversifying its overall energy mix.

Key Findings

CATL, the global leader in battery manufacturing headquartered in China, and Solarpro, the renewable energy division of the Vienna-based Renalfa Solarpro Group, have formalized a strategic agreement to deploy 2 Gigawatt-hours (GWh) of sodium-ion battery storage systems across the Central and Eastern European (CEE) region. This landmark initiative represents the inaugural large-scale implementation of sodium-ion storage technology in CEE, projected to substantially transform the region’s energy infrastructure and accelerate its decarbonization trajectory.

Technical Specifications and Strategic Synergy

At the heart of this deployment is CATL’s advanced ‘TENER Sodium system’. This innovative system is engineered for exceptional longevity, capable of achieving up to 15,000 full charge-discharge cycles. This robust cycling capability translates to an operational lifespan of approximately 25 to 30 years in real-world stationary energy storage applications, representing a significant extension over many conventional battery chemistries. Sodium-ion batteries inherently offer superior cost efficiency compared to lithium-ion counterparts, largely owing to the global abundance of sodium as a raw material and the elimination of expensive, supply-volatile elements such as cobalt and nickel from their chemistry. Moreover, the TENER Sodium technology exhibits stable performance across a wide operational temperature range and incorporates advanced safety characteristics. The synergy between CATL’s cutting-edge battery technology and Solarpro’s deep expertise in developing and operating renewable energy projects across the CEE region, combined with their market insights and robust deployment capabilities, is poised to deliver highly efficient and sustainable energy storage solutions.

Strategic Impact and Future Outlook

The deployment of 2 GWh of sodium-ion battery storage systems is projected to have a transformative impact on the CEE region’s energy infrastructure, substantially improving renewable energy integration and enhancing grid stability. The extended operational lifespan of the TENER Sodium system will not only reduce the initial investment payback period but also significantly lower total life-cycle costs, thereby elevating the economic viability and attractiveness of large-scale energy storage projects. This pioneering implementation is anticipated to serve as a compelling case study, fostering broader adoption of sodium-ion battery technology in other CEE nations and across global markets confronting similar energy transition challenges. The strategic collaboration between CATL and Solarpro is poised to establish a vital model for constructing a sustainable, resilient, and decarbonized energy future.
