First large-scale U.S.-owned and U.S.-operated advanced electrolyte production facility strengthens Kentucky’s battery supply chain
FRANKFORT, Ky. (Dec. 15, 2025) — Kentucky Governor Andy Beshear today announced that Anthro Energy Inc., an advanced materials and battery technology company, will establish a new manufacturing operation in Louisville, investing more than $42 million and creating 110 full-time, high-quality jobs, along with approximately 390 construction jobs during development.
“Kentucky’s manufacturing sector continues to drive our historic economic momentum,” said Governor Andy Beshear. “We are seeing innovative, high-growth companies like Anthro Energy choose the commonwealth for expansion, bringing well-paying jobs and cutting-edge technologies with them. Our central location, skilled workforce and pro-business environment make Kentucky an ideal home for advanced manufacturing, and this project is a major win for Louisville and the region.”
Anthro Energy’s new Louisville facility will be the company’s first operation in Kentucky and will focus on advanced electrolyte production for next-generation battery systems. The site will become the first large-scale, U.S.-owned and U.S.-operated advanced electrolyte manufacturing facility in the country, supporting domestic supply chain resilience for critical battery materials.
The company has developed a proprietary injectable phase-change electrolyte (IPCE), trademarked Anthro Proteus, designed to improve both energy density and safety across a wide range of battery applications, including consumer electronics, micromobility, defense and automotive technologies. At full capacity, the Louisville facility is expected to produce more than 12,000 metric tons of IPCE annually.
The project will create 110 new full-time positions in Jefferson County, including production manufacturing technicians, process and controls engineers, facility managers, accounting professionals, and maintenance and warehouse technicians, many of which are highly skilled, high-wage roles.
“We’re grateful to have earned the Department of Energy’s approval and are excited to begin scaling production of our advanced electrolytes here in Kentucky,” said Joe Papp, Chief Technology Officer of Anthro Energy and a Kentucky native. “This facility represents a major milestone—not just for Anthro, but for the future of U.S.-based battery manufacturing. Building the first major domestically owned advanced electrolyte facility here helps strengthen our national energy supply chain, and bringing this work back to Kentucky is deeply meaningful to me.”
Beyond manufacturing, Anthro Energy plans to actively engage with the local workforce ecosystem, partnering with organizations such as Kentuckiana Works, Jefferson County Technical College, KY FAME, Fort Campbell, Fort Knox, and KY Valor to support workforce development, training, recruitment and veteran employment initiatives.
Founded in 2021, Anthro Energy is an advanced materials company focused on solving the longstanding tradeoff between energy density and safety in modern batteries. The company delivered its first prototype cells in its founding year and has since established production operations in California, securing key battery certifications and shipping its first commercial products. Anthro Energy remains committed to advancing scalable electrolyte technologies that redefine battery performance across global markets.
Louisville Mayor Craig Greenberg welcomed the investment, noting the city’s strength in advanced manufacturing. “Anthro Energy’s decision to build its first U.S.-owned electrolyte production facility in Louisville reinforces our city’s position as a premier destination for future-focused manufacturing,” Greenberg said. “This project brings more than 100 good-paying jobs to our community and further solidifies Louisville’s leadership in energy innovation.”
Trevor Pawl, CEO of the Louisville Economic Development Alliance, emphasized the project’s national significance. “This investment places Louisville at the intersection of two critical priorities: energy independence and high-tech manufacturing,” Pawl said. “Anthro Energy’s expansion is a major step forward in strengthening the advanced materials and battery supply chain, and we’re excited to support their long-term growth in our community.”
