Anthro Energy will invest $42 million in a Louisville electrolyte manufacturing facility, creating 110 jobs and strengthening U.S. battery supply chains.
Louisville Mayor Craig Greenberg has announced a significant new investment that further strengthens the city’s position as a growing hub for advanced manufacturing and energy innovation. Anthro Energy, Inc., a next-generation battery technology company, has selected Louisville as the location for its first large-scale, U.S.-owned and operated advanced electrolyte manufacturing facility. The project represents an investment of approximately $42 million and is expected to create 110 permanent, full-time jobs, in addition to supporting around 390 construction jobs during the buildout phase.
Mayor Greenberg highlighted the strategic importance of the project for the city’s economic future. He emphasized that Anthro Energy’s decision reflects Louisville’s attractiveness as a destination for forward-looking manufacturers and technology-driven companies. According to the Mayor, the new facility will bring more than 100 high-quality, well-paying jobs to the local economy while reinforcing Louisville’s leadership in advanced energy solutions and modern manufacturing industries.
The planned facility will mark Anthro Energy’s first operation in the Commonwealth of Kentucky and will focus on the production of advanced battery electrolytes. Central to the operation is the company’s proprietary injectable phase change electrolyte (IPCE), marketed under the trademark Anthro Proteus™. This innovative technology is designed to address long-standing challenges in battery performance by balancing energy density and safety. The electrolyte can be adapted for a wide range of applications, including consumer electronics, micromobility solutions, defense systems, and automotive technologies. Once fully operational, the Louisville plant is expected to produce more than 12,000 metric tons of IPCE annually.
The 110 new permanent positions generated by the project will span a variety of highly skilled roles. These include production manufacturing technicians, process and control engineers, facility management staff, accounting professionals, as well as maintenance and warehouse technicians. Collectively, these positions are expected to offer competitive wages and benefits, contributing to long-term workforce development in the region.
Trevor Pawl, CEO of the Louisville Economic Development Alliance, noted that the investment places Louisville at the intersection of two critical national priorities: strengthening domestic energy independence and expanding high-tech manufacturing capacity. He described Anthro Energy’s expansion as a milestone in the city’s evolution into a center for advanced materials and battery supply chain innovation, particularly in the South End of Louisville.
Beyond the manufacturing operation itself, Anthro Energy plans to actively engage with the local community. The company intends to build partnerships across Louisville and Jefferson County to support workforce development, education, and recruitment. Planned collaborations include organizations such as Kentuckiana Works, Jefferson County Technical College, KY FAME, U.S. Army Fort Knox, Fort Campbell, and KY Valor, among others.
Joe Papp, Chief Technology Officer of Anthro Energy and a Kentucky native, expressed personal pride in bringing the company’s advanced electrolyte production to the state. He stated that the Louisville facility will represent the first major U.S.-owned and U.S.-operated advanced electrolyte production site, helping establish a resilient domestic supply chain for critical battery materials while enabling the next generation of energy technologies.
Founded in 2021, Anthro Energy focuses on advanced materials that overcome traditional trade-offs between battery safety and energy density. The company delivered its first prototype cells to customers in its founding year, later establishing a production facility in California, securing key battery certifications, and shipping its first commercial products. Today, Anthro continues to pursue scalable, transformative electrolyte technologies for global markets.
To support the project, the Kentucky Economic Development Finance Authority (KEDFA) preliminarily approved a 10-year incentive agreement under the Kentucky Business Investment program. The agreement may provide up to $2 million in tax incentives, based on the company meeting targets related to job creation and an average hourly wage of $39.32, including benefits. Additional incentives of up to $340,000 were approved through the Kentucky Enterprise Initiative Act, allowing the company to recover eligible sales and use taxes on construction and equipment costs. Anthro Energy may also access further state and local grants, workforce services, recruitment assistance, and customized training programs to support its long-term growth in Louisville.
