Partnership Targets First Sodium-Ion Storage Project in Central and Eastern Europe
CATL and Solarpro Technology AD have signed a strategic cooperation agreement for 2 GWh of sodium-ion battery systems. The deal marks a notable step forward for next-generation storage technology and the push for more resilient energy infrastructure across Eastern Europe.
The partnership will use sodium-ion technology's unique strengths — particularly its strong low-temperature performance and extended cycle life — to develop tailored storage solutions for various applications throughout Central and Eastern Europe. The companies plan to commission the region's first sodium-ion energy storage project.
Regional Expertise Meets Global Innovation
Solarpro brings strong regional know-how, with a solid track record in turnkey project delivery, system integration, and long-term O&M across Eastern Europe's renewable energy sector. For CATL, the collaboration offers valuable insight into local market dynamics, operational challenges, and emerging use cases for its sodium-ion technology.
CATL, a global leader in sodium-ion battery innovation backed by advanced R&D, system design, and field validation capabilities, will work with Solarpro to refine storage solutions optimized for the region's climate conditions, grid requirements, and evolving energy landscape. The goal is to accelerate large-scale adoption of sodium-ion technology in Eastern Europe.
What Executives Said
Krasen Mateev, CEO of Solarpro Holding, said: "We see strong potential for sodium-ion deployment in Lithuania and other Eastern European markets given its clear advantages in low-temperature performance and long cycle life. We look forward to working with CATL to further optimize these solutions and identify the most suitable application scenarios."
Amanda Xu, CTO of ESS and President of ESS Europe at CATL, said: "The efficient teamwork between the two teams has revealed great potential. We look forward to the successful implementation of the first sodium-ion battery project in Central and Eastern Europe."
Building on Existing Partnership
The new agreement builds on an existing relationship between the two companies. In May 2026, CATL and Solarpro successfully connected a 602 MWh large-scale battery storage project to Bulgaria's national power grid, increasing the country's total energy storage capacity by 10%.
