Alfen and CATL Reach 5 GWh Sodium-Ion Battery Storage Partnership in Europe

Alfen N.V., a leading European energy solutions provider, and Contemporary Amperex Technology Co., Limited (CATL), the world's largest battery manufacturer, today announced their collaboration to deploy 5 GWh of CATL's advanced sodium-ion battery energy storage systems across Europe. This brings the two companies' long-standing partnership to a new level, opening a new chapter of diversified, technology-driven development supporting Europe's energy transition. 

Since the start of their collaboration, Alfen and CATL have worked closely on lithium-ion energy storage projects. Back in 2023, the two parties began a long-term battery supply partnership, which was expanded in 2024 to accommodate Alfen's growing demand for energy storage deployment in Europe. 

"Sodium-ion is the next step in how we think about energy storage - more diversified, resilient, and built for where the market is heading. This step with CATL puts us ahead of that curve and we're looking forward to continuing this partnership."

- Michael Colijn, CEO, Alfen

"We are excited to partner with Alfen, one of our key strategic partners, to accelerate the deployment of next-generation energy storage technologies across Europe. With their superior safety performance and lifecycle sustainability advantages, sodium-ion batteries will deliver unique value to European customers and support the region's transition to a cleaner, more resilient energy future."

-Tan Libin, Chief Customer Officer & Co-President of Sales and Marketing, CATL

This initiative establishes forward-looking cooperation on next-generation, low-cost energy storage solutions, and the opening of new business opportunities beyond traditional lithium-ion battery storage supply.

It enables Alfen to diversify its battery material portfolio, optimise the cost structure of its energy storage products, strengthen resilience against lithium price volatility, enhancing its competitiveness in mid-to-large scale European project tenders.

Joint deployment of sodium-ion projects with Alfen allows CATL to accumulate localised European grid application experience for sodium batteries, optimize product adaptation to European grid codes, and accelerate the global scaling of sodium-ion energy storage shipments.

The two companies will jointly accelerate the large-scale adoption of sodium-ion energy storage across Europe and support the continent's energy transition and renewable integration, opening a new era in cross-border clean-energy collaboration.
