Natron Energy to build a battery gigafactory in Valais

American start-up Natron Energy is developing an innovative electric battery technology that will be manufactured in Valais.

Natron Energy Prussian blue
Natron Energy is developing a unique battery technology using Prussian blue, a less expensive, more durable, more efficient and more environmentally friendly solution than traditional batteries.

Based at the Energypolis Campus in Sion, Natron Energy is a spin-off from Stanford University (California) whose technology extends the life of batteries, considerably reduces the risk of fire or explosion and is environmentally friendly.

With more than sixty employees spread between Santa Clara and Sion, the company has initiated a small-scale commercialization of its first batteries for American data centers.

Concurrently, Natron Energy is actively preparing the construction of its first manufacturing plant in Sion, with the support of the canton of Valais, the NanoDimension Fund and Lonza.

The most significant factory project in the energy transition field

With a budget of more than CHF 100 million, Natron Energy's Valais plant represents the largest plant project related to the energy transition in French-speaking Switzerland for the coming years.

After securing the necessary plots of land, Natron is now selecting the real estate developer for this plant, which should be up and running within two years, and initially create about 50 jobs.

"The creation of a Natron Energy plant is primarily the result of the American company's collaboration with Lonza in Visp. The Swiss group will produce the Prussian blue needed to manufacture Natron's electrodes. Estimated at more than CHF 100 million [...], the investment in the Sion manufacturing facility is intended to create the production tool for all Natron electrodes," explains Colin Wessells, founder of Natron.
