PHENOGY was founded based on the principles of dedication, experience and ingenuity.
PHENOGY moves the energy ecosystem forward – giving businesses control over the energy that drives them. Founded in 2019 and headquartered in Root near Lucerne, Switzerland, we develop battery energy storage systems built on sodium-ion technology.
At the center are solutions for our customers: storage systems that optimize local energy use. By storing self-generated solar power, for instance, or absorbing costly demand peaks. During a power outage or supply shortfall, they keep critical operations running. That spans commercial businesses and industrial parks to sites with particularly high requirements, such as hospitals or data centers.
Sodium-ion battery storage tolerates a much wider temperature range than conventional lithium-ion batteries. It's also generally considered less prone to thermal runaway in research – an advantage confirmed repeatedly in independent studies.
The technology also has advantages over conventional storage systems from a political standpoint. Sodium is available worldwide – unlike lithium and cobalt, whose supply chains are concentrated in a handful of countries and exposed to export restrictions, trade conflicts, or blocked shipping routes.
In 2025, PHENOGY brought Europe's first large-scale sodium-ion storage system online in Bremen – proof that our technology works in practice. Our ambition now: to grow, step by step, from a startup into a global energy storage provider.
We believe this: without control over your own energy supply, you lose independence – as a company, a region, a society. Our offer: storage systems that make your energy supply more resilient and more independent.

Our Strategy
Fueled by carbon, humankind has developed faster than ever in the last two centuries. We pioneered industry. We invented mobility. We created communication technology. Blinded by the success, we forgot the fundamentals of our existence: our habitat and each other. Now’s the time for a shift.
Our Purpose
We foster prosperity for people and our planet, ensuring true growth and a dignified livelihood for all.
Our Mission
PHENOGY catalyzes the creation of sustainable energy storage solutions that are equally affordable, available, safe, and reliable to transform user’s behavior into circular economy.
Our Vision
We energize the future.
Sustainably.
Our Manifesto
What is our plan for a better tomorrow? What drives us as people? As a company? As innovators in sustainable energy storage solutions? As a guiding post, we have written a manifesto that reflects our purpose. If you are keen to understand what's behind PHENOGY, take your time to watch the video.
The United Nations' sustainability agenda is an important source of inspiration for us. As a team, we're guided in particular by the following goals.
We want to help improve access to clean energy.
We're working on innovations for a resilient, future-ready energy infrastructure.
We want to help businesses and public institutions use energy more efficiently.
We build on widely available raw materials as a basis for more responsible production.
We want to help reduce reliance on fossil-generated power – and with it, harmful climate emissions.
