CATL has inked a significant 2 GWh deal with Central and Eastern Europe’s Solarpro to develop the region’s first large-scale sodium-ion battery energy storage project, using advanced technology tailored for harsh winter climates.
- 2 GWh sodium-ion battery project to launch later this year.
- System offers up to 15,000 cycles and 25-30 years lifespan.
- Designed for cold climates, retaining 92% capacity at -20°C.
What happened
CATL has signed a deal with Solarpro, a prominent renewable energy firm in Central and Eastern Europe, to jointly develop a pioneering 2 GWh sodium-ion battery energy storage system in the region. This project will utilize CATL’s proprietary Tener Sodium technology, which has been designed for durability and efficiency under extreme weather conditions.
The initiative marks the region’s first large-scale deployment of sodium-ion energy storage, scheduled to begin later this year. This follows previous collaborations where CATL and Solarpro delivered high-capacity lithium battery systems to Bulgaria’s power grid, boosting its energy storage capacity substantially.
Why it matters
The project represents a strategic advancement in energy storage technology for Central and Eastern Europe, a region facing challenging winter environments. CATL’s sodium-ion system offers longevity with up to 15,000 charge cycles and a lifespan of 25 to 30 years, addressing the need for sustainable and reliable grid storage solutions.
Furthermore, the system’s exceptional low-temperature performance, maintaining 92% capacity at -20°C, makes it highly suitable for countries like Lithuania where extreme cold is common. This reliability under harsh conditions can enhance grid stability and support the region’s renewable energy integration goals.
What to watch next
Observers should track the project’s rollout and operational performance once deployed later this year, as it could set a precedent for the adoption of sodium-ion battery technology in similarly cold climates worldwide. Success here may encourage broader use of sodium-ion systems as a complement or alternative to traditional lithium-ion batteries in large-scale storage.
Additionally, the ongoing partnership between CATL and Solarpro may lead to further innovations and expansions in energy storage capacity within Central and Eastern Europe, potentially accelerating the region’s transition to cleaner and more resilient energy infrastructure.
