DOE Backs Princeton NuEnergy’s $110M Closed-Loop Battery Facility

Princeton NuEnergy Inc. (PNE), a U.S.-based advanced battery materials company, has been selected to enter negotiations for a $50 million grant from the U.S. Department of Energy (DOE). The funding will support the development of a domestic closed-loop Cathode-to-Cathode® rejuvenation facility in Commerce, Georgia.

The proposed project represents a total investment of $110 million, comprising the DOE grant and $60 million in company cost sharing. Once operational, the facility is expected to have an annual processing capacity of 3,000 tons and create about 70 permanent manufacturing positions, along with approximately 100 construction jobs.

The facility will use PNE’s proprietary low-temperature plasma-assisted separation (LPAS™) technology to process nickel-based lithium-ion battery manufacturing scrap. Rather than completely breaking down spent cathode materials into individual elements, the company’s direct-recycling technology is designed to preserve and rejuvenate their engineered structure. The recovered cathode active material can then be returned directly to battery manufacturing, supporting a more integrated domestic supply chain.

PNE said the facility could create a closed-loop system capable of returning rejuvenated cathode active material to battery production in approximately seven days. This approach could shorten supply chains, reduce material handling requirements, and improve the efficiency of battery-material recovery.

According to the company, its Cathode-to-Cathode® process can produce rejuvenated cathode active material at a cost approximately 45% lower than comparable virgin material, while avoiding significant damage to the cathode structure. If achieved at commercial scale, the cost advantage could improve the economics of recycling and increase the competitiveness of domestically produced battery materials.

The Commerce facility is also intended to establish a domestic source of battery-grade nickel-manganese-cobalt (NMC) cathode active material. By recovering material from manufacturing scrap and returning it to battery production, the project could reduce dependence on imported battery materials and contribute to U.S. critical-mineral security.

PNE Chief Commercial Officer Joe Fisher described the DOE selection as an important validation of the company’s direct-recycling technology and its potential for commercial-scale deployment. Founder and CEO Dr. Chao Yan also highlighted the support from the DOE’s Office of Critical Minerals and Energy Innovation and Manufacturing Deployment Office.

The Commerce project is expected to serve as a commercial demonstration of PNE’s modular Cathode-to-Cathode® platform. Successful operation could provide a foundation for deploying similar closed-loop recycling facilities near battery manufacturing centers across the United States.

Impact on the Product and Chemical Commodity Prices

The project is likely to have a positive long-term impact on recycled cathode materials and battery-grade NMC feedstocks, as commercial-scale deployment could increase domestic availability and reduce production costs. The claimed 45% cost advantage over virgin material could place downward pressure on demand for newly produced nickel, manganese and cobalt used in cathode manufacturing, particularly as recycling capacity expands. However, the immediate impact on commodity prices should remain limited because the 3,000-ton-per-year facility is relatively small compared with global battery-material consumption and is still at the grant-negotiation stage. Over time, greater recycling could moderate nickel, cobalt and manganese prices by reducing dependence on primary raw materials.
