Phenogy will present a scalable sodium-ion storage system for commercial and industrial applications at The smarter E Europe 2026 trade show in Munich.

Swiss energy storage provider Phenogy, headquartered in Root in the canton of Lucerne, will present its new PHENOGY 1.1 storage system at The smarter E Europe 2026 trade show in Munich. The company will showcase the air-cooled sodium-ion battery at booth C3.514, targeting commercial and industrial users.

According to Phenogy, the modular storage system was developed for applications such as peak load management, self-consumption optimization, microgrids, emergency power supply, charging infrastructure for electric vehicles, and energy trading. The company sees a growing demand for storage solutions that offer not only electricity storage but also digital connectivity and flexible deployment options.

Phenogy 1.1 is part of the “Series 1” product family and represents the cabinet-based variant of a scalable storage platform. According to the company, this platform ranges from compact systems to large-scale container-based storage solutions. The modular design is intended to allow operators to adapt storage capacity to different site requirements.

The company notes that battery storage systems are increasingly taking on additional roles in decentralized energy systems. In addition to balancing electricity supply and demand, they are intended to enhance supply reliability, support local value creation, and enable digital control functions.

Technologically, Phenogy relies on sodium-ion cells. According to the company, this battery technology offers high thermal stability and reduces the risk of overheating and thermal runaway. The system integrates the battery, cooling unit, and inverter into a single enclosure. This is intended to simplify planning and installation.

Regarding operation, the company highlights the temperature resistance of sodium-ion technology. The cells are less sensitive to extreme temperatures than other battery types, thereby enabling stable performance even under demanding conditions. The air-cooled system features a comparatively simple architecture, which can reduce maintenance requirements.

Peter E. Braun, CEO and co-founder of Phenogy, sees the role of battery storage in the energy system as evolving. In the future, storage systems will need to do more than just store electricity; they must also support resilience, energy sovereignty, and integration into networked infrastructures, Braun explained in a company press release.

With its presentation at The smarter E Europe, Phenogy says it is underscoring its focus on decentralized energy systems. The company is relying on a combination of modular design, sodium-ion technology, and digital system integration.
