Thermal battery manufacturer Antora is growing rapidly to meet the demand for its products (The Mercury News, subscription).

What’s going on: This month, the company announced the completion of a two-building expansion of its San Jose, California, manufacturing campus, “a move that enabled [it] to more than double its space.”

• The firm, which makes energy storage technology that converts low-cost electricity into always-on heat and power, is “seeing unprecedented demand” for its technology, Antora Chief Operating Officer Justin Briggs told the news outlet. “Industrial electrification, data centers. We are really focused on data center expansion.”
• Antora now has over 100,000 square feet of manufacturing and operations space, up from just over 50,000.

Why it’s important: The energy stored in Antora’s thermal batteries “can be delivered 24/7 to manufacturers as affordable, reliable energy,” the NAM wrote in an original article in May 2025.

• “It’s a solution that is both modular and scalable, capable of serving small and large manufacturers alike.”

More online, faster: “We’ve already shipped gigawatt-hours of storage to industry in the Midwest, with more going out the factory door every day,” said Antora Co-Founder and Chief Commercial Officer David Bierman about the new expansion.

• “This expansion means that we can get major projects online faster—enabling the speed to power that this moment requires.”

The NAM’s view: “Antora’s batteries are manufactured in the U.S. and are a prime example of how we can avoid dependence on China for critical minerals,” said NAM Vice President of Domestic Policy Chris Phalen.

• “The company’s expansion is good news for the U.S., our energy and national security and our allies.”
