Anthro Energy, a next-generation battery technology company, announced plans to build the first large-scale, US-owned and operated advanced electrolyte manufacturing facility in Louisville, Kentucky, a move set to reshape America’s battery supply chain.

 

The Louisville site, located in the city’s South End, will be transformed into a 25 GWh manufacturing hub, producing 12,000 metric tons annually of Anthro Proteus, the company’s patented advanced polymer electrolyte. The material is critical for next-generation lithium-ion batteries, boosting safety, energy density, and compatibility with technologies like silicon anodes and high-voltage cathodes.

 

“As a Kentucky native, I'm especially proud to bring this project home,” said Joe Papp, Chief Technology Officer of Anthro Energy. “This facility represents more than innovation; it represents a commitment to building advanced energy solutions on American soil, with American talent. By onshoring critical battery-supply-chain infrastructure, we're strengthening both our national security and our industrial base. We look forward to contributing to Kentucky's leadership in the advanced battery economy and ensuring that this essential technology is built here at home, where it belongs.”

 

Governor Andy Beshear hailed the move as a major win for the state. “Anthro Energy's investment is a win for Louisville and a win for Kentucky,” he said. “We're proud to support a company that's bringing innovation, opportunity, and momentum to the Commonwealth.”

 

The project is backed by federal and state support, including a $24.9 million grant from the US Department of Energy and $18.4 million in investment tax credits from the Inflation Reduction Act’s 48C Qualifying Advanced Energy Project Tax Credit program. Additional local incentives exceed $3 million, spanning grants and tax breaks from the Kentucky Cabinet for Economic Development, KEDFA, and the Kentucky Enterprise Initiative Act.

 

At full scale, the Louisville facility will generate over 110 full-time jobs and support more than 390 construction roles, focusing on skilled manufacturing, engineering, and operations. Anthro is also investing over $1 million in workforce development.

 

“This project puts Louisville at the center of two national priorities: energy independence and high-tech manufacturing,” said Trevor Pawl, CEO of the Louisville Economic Development Alliance. “Anthro's investment marks a major step forward in our city's evolution as a hub for advanced materials and battery supply chain innovation. We're excited to welcome them to the South End and look forward to supporting their growth in Louisville.”

 

The Louisville plant complements Anthro’s Alameda, California headquarters, which will continue to handle R&D and pilot-scale operations, expanding the company’s national footprint while boosting domestic electrolyte production.

 

“Anthro's decision to build its first US-owned electrolyte production facility right here in Louisville once again shows our city is the best place to do business and is the epicenter of future-focused manufacturing,” said Louisville Mayor Craig Greenberg. “This investment adds more than 100 good-paying jobs to our local economy and cements Louisville's leadership in energy and advanced manufacturing.”
