Peter E. Braun, CEO and Co-FounderThe technology leader will alter the future of energy systems by enabling independence in supply and operations through domestic sourcing, manufacturing and big energy data. This comes from PHENOGY’s conviction that energy should be decentralized – across industries, infrastructure, and commerce, and truly integrated – from sourcing to manufacturing to operations.
This vision has manifested in its sodium-ion systems, which are built with safety, scalability, cost-efficiency, transparency, and long lifecycle performance. The company offers a credible alternative to lithium-ion batteries with a minimized eco-footprint and maximized supply chain resilience.
Sodium-ion chemistry harnesses a naturally abundant, thermally stable element, addressing thermal volatility, one of energy storage’s most critical challenges. PHENOGY systems are fire safe, making them ideal for extreme conditions and mission-critical sites like hospitals, data centers, as well as military and civil infrastructure.
Game-changer by design
While many technologies disrupt, PHENOGY’s approach is to integrate. Its modular technology platform was designed for interoperability, connecting seamlessly to existing grids and microgrids, with the benefit to avoid costly upgrades, e.g. for EV charging-infrastructure. Its intelligent system management ensures smooth, dependable operation across all applications, including peak shaving, renewable balancing, and backup during grid downtime.
PHENOGY’s innovation extends beyond engineering. The company collaborates with leading research institutions and technology partners to keep its systems secure, scalable, and future-ready. Whether supporting public utilities, industrial hubs, or smart cities chasing carbon neutrality and resilience, PHENOGY adapts quickly, proving that collaboration is the fastest route to future-proof energy supply.
Resilience has become the new reliability as news of climate volatility and fragile grids increases. PHENOGY’s sodium-ion platforms act as silent guardians, keeping hospitals, data centers, and water treatment plants running when everything fails. Ai-driven energy data analytics coupled with intelligent systems management enable rapid, real-time response, and efficient operations. In addition, its modularity adds redundancy to maintain critical services even in high-risk or high-demand zones.
PHENOGY’s systems are infrastructure insurance, built to protect what matters most when the unexpected strikes.
Circular by Design
At PHENOGY, sustainability forms the blueprint. The company uses sodium, an abundant and environmentally friendly element, to reduce reliance on scarce and politically sensitive resources. Each battery system design aims for circularity.
Even the production process reflects that ethos. Unlike traditional lithium-ion systems, PHENOGY’s batteries contain no toxic heavy metals, simplifying recycling and minimizing environmental impact. From cell structure to control electronics, every design decision aligns with a circular, eco-conscious energy ecosystem.
PHENOGY’s promise came to life in Bremen, Germany, with the commissioning of Europe’s first large-scale sodium-ion battery energy storage system in 2025. Serving the industrial grid applications such as EV hyper-charging, the Bremen installation demonstrated measurable improvements in power consumption, significant CO₂ reductions, and increased renewable energy use. It became a benchmark for sustainable infrastructure, showing how local energy independence can look in the real world.
As nations accelerate toward electrification and decarbonization, PHENOGY reminds us that innovation must go hand in hand with responsibility. Its sodium-ion technology proves that the next generation of energy systems can be safe, sustainable, and accessible for industries and humanity.
