Sodium-ion Battery storage is moving closer to large-scale deployment in Europe. HD Advanced Technologies GmbH and PHENOGY AG have launched a broad partnership to speed up production, installation, and service for stationary battery energy storage systems. At the same time, both companies are preparing a joint venture to develop and manufacture sodium-ion battery cells in Europe.
This collaboration brings together PHENOGY’s sodium-ion cell chemistry and system design with HEIDELBERG’s industrial manufacturing and printing expertise. As a result, the partners aim to build a European technology and industry platform that supports energy sovereignty, local value creation, and faster market rollout.
Sodium-ion battery storage partnership targets European scale
PHENOGY AG, based in Root near Lucerne, and HD Advanced Technologies, a wholly owned subsidiary of Heidelberger Druckmaschinen AG, signed two closely linked agreements. First, HD Advanced Technologies will manufacture complete PHENOGY energy storage systems. Second, both companies will lay the foundation for a joint venture focused on sodium-ion battery cells.
Together, these agreements cover a large part of the value chain. They include cell chemistry, cell design, system design, industrial production, rollout, installation, service, and maintenance. Therefore, the partnership creates a more integrated path from research to commercial deployment.
How HDAT will expand sodium-ion battery storage production
Under a long-term framework supply agreement, HD Advanced Technologies will handle industrial production of cabinets, containers, and related system products for PHENOGY. The company will also support procurement, electronics manufacturing, final assembly, rollout, installation, service, and maintenance.
Initially, production will take place in Germany for the European market. Later, the partners plan to expand manufacturing into the United States for North America. This step-by-step model should help PHENOGY scale supply while keeping operations close to regional customers.
Moreover, HD Advanced Technologies will use local supply chains and its industrialization expertise to support efficient production. This approach matters because battery buyers often need reliable delivery, service support, and clear quality standards. By managing the full production chain, HDAT can help PHENOGY bring systems to market faster.
Sodium-ion battery storage joint venture will focus on cells
The planned joint venture will focus on developing and industrially manufacturing sodium-ion battery cells. PHENOGY will contribute its cell chemistry and cell design. HEIDELBERG will add a specialized printing process that supports advanced battery production.
Because both partners bring complementary strengths, they can cover the full development cycle. That cycle includes research, engineering, pilot work, and industrial-scale manufacturing. In addition, the structure can support new cell formats with specific design and performance requirements.
The companies said the joint venture will target applications with high demands. These include critical infrastructure, defense, and mobility. As a result, the platform will not only serve stationary energy storage but also support specialized markets that need durable and high-performance battery solutions.
Why sodium-ion battery storage matters for Europe
Sodium-ion battery storage offers clear strategic value for Europe. The technology does not require lithium or cobalt. Instead, it relies on widely available raw materials. Therefore, it supports more resilient supply chains and strengthens long-term supply security.
For Europe, that matters at a time when governments and industries want more control over energy technology. This partnership directly addresses that goal. It connects local manufacturing with regional system deployment and future cell production. Consequently, it can help reduce dependence on non-European supply chains.
The partnership also supports Europe’s broader push for decentralized and resilient power systems. Stationary battery storage plays a growing role in balancing grids, supporting renewable energy, and improving energy reliability. With local production capacity, customers can gain faster access to battery systems designed for European needs.
Company roles in the sodium-ion battery storage platform
HD Advanced Technologies combines industrial capabilities in defense, security, and energy. As part of HEIDELBERG, it builds on established manufacturing, integration, and systems expertise. That background makes it well suited to industrialize complex energy systems at scale.
PHENOGY, founded in 2019, develops battery energy storage systems based on sodium-ion technology. The company employs more than 60 people across Switzerland, Germany, the United States, and Singapore. It also works with select Fraunhofer Institutes and the University of South Carolina. This network strengthens its research and development base.
Thanks to this collaboration, PHENOGY can focus more strongly on advancing its cell chemistry and system design. Meanwhile, HD Advanced Technologies can drive series production and operational scaling. In short, each partner can concentrate on its core strength while building a shared industrial platform.
Sodium-ion battery storage supports energy sovereignty
The HD Advanced Technologies and PHENOGY partnership sets a clear direction for battery development in 2026. It links technology development with industrial execution. It also combines local manufacturing, battery expertise, and long-term scaling plans.
Most importantly, the agreement gives Europe a stronger route to sodium-ion battery storage deployment. The manufacturing deal supports faster delivery of energy storage systems. Meanwhile, the planned joint venture supports future cell production within Europe. Together, these steps create a practical platform for regional battery growth.
As demand for stationary storage rises, partnerships like this can play a central role in building secure and scalable energy infrastructure. With production starting in Germany, expansion planned for North America, and cell development under preparation, HDAT and PHENOGY are positioning sodium-ion battery storage as a serious industrial priority for 2026 and beyond.
