Technology Comparison and Battery Longevity

For this episode of the Data Center Frontier Show podcast, we sit down with Brian Kennedy, Director of Business Development and Marketing at Natron Energy.

As recounted by Kennedy in the course of our talk, Colin Wessells founded Natron Energy as a Stanford PhD student in 2012. His vision in building the company, which started in a garage in Palo Alto, was to deliver ultra-safe, high-power batteries. 

As stated on the company's website, "After countless hours of development with an ever expanding team of scientists and engineers, Natron now operates a state of the art pilot production line for sodium-ion batteries in Santa Clara, California."

The company notes that most industrial power utilizes decades-old, more environmentally hazardous battery technology such as lead-acid and lithium-ion. 

In contract, Natron says its "revolutionary sodium-ion battery leverages Prussian Blue electrode materials to deliver a high power, high cycle life, completely fire-safe battery solution without toxic materials, rare earth elements, or conflict minerals."

In 2020, Natron became the world’s first sodium-ion battery to achieve a UL 1973 listing for its battery product, and commercial shipments to customers in the data center, forklift, and EV fast-charging markets soon began. 

Natron notes that its technology leverages standard, existing li-ion manufacturing techniques, allowing the company to scale quickly. With U.S. and Western-based supply chain and factory agreements in place, Natron says it saw its manufacturing capacity increase 200x in 2022. 

In the course of the podcast discussion, Natron's Kennedy provides an update on Natron's data center industry doings this year and into next year. Here's a timeline of key points discussed:
