Graphite One Advances Ohio Project to Build U.S. Graphite Supply Chain
Graphite One Inc. has moved its planned Active Anode Materials (AAM) facility in Conneaut, Ohio, into a detailed execution phase following the signing of a new engineering contract and the advancement of site development. The company aims to establish a domestic production capacity of 25,000 tonnes of synthetic graphite per year by the fourth quarter of 2028, a move intended to reduce U.S. reliance on foreign graphite imports.
Did You Know? Graphite constitutes approximately 95% of a lithium-ion battery anode by weight, making it a critical component for electric vehicles, grid-scale energy storage, and various defense technologies.
Engineering and Infrastructure Progress
On June 16, 2026, Graphite One finalized an engineering contract with a firm specializing in anode production facilities. This agreement is designed to optimize manufacturing systems and reduce project risk as the company transitions from planning to implementation. According to the company, the engagement focuses on integrating high-temperature processing equipment to ensure the facility meets commercial-scale requirements.
The Conneaut manufacturing site, secured in May 2026 through an agreement with a subsidiary of CN Railway, provides the necessary industrial infrastructure for the project. The location offers direct access to Great Lakes shipping and existing high-capacity electrical service, which the company states will help lower capital intensity and accelerate development timelines.
Phased Development and Economic Impact
Graphite One has outlined a two-phase development strategy for its Ohio facility. The first phase targets the completion of finishing and blending operations by the fourth quarter of 2027, with an initial capacity of 10,000 tonnes per year. The second phase, scheduled for completion in late 2028, involves the installation of graphitization systems to reach the full 25,000-tonne annual capacity.
The project is expected to create 30 to 40 permanent jobs in the Ashtabula County region during the first phase, with an additional 100 to 120 positions anticipated following the Phase 2 expansion. Environmental assessments and permitting for the site are currently underway, with completion projected for the first quarter of 2027.
Strategic Context for Domestic Supply
The push for domestic graphite production comes as demand in North America is projected to surge. Data from S&P Global Mobility indicates that graphite demand for battery applications could grow eleven-fold, rising from approximately 56,000 tonnes in 2023 to more than 620,000 tonnes by 2030. Currently, the United States remains heavily dependent on processed anode materials sourced primarily from China.
Expert Insight: Samantha Carter notes that the move toward vertical integration—linking Alaska-based mining with Ohio-based processing—represents a deliberate strategy to meet the traceability and domestic content requirements mandated by the Inflation Reduction Act. By controlling the supply chain from raw material to finished anode, the company aims to mitigate the risks associated with long-distance ocean imports and address the supply gap identified by industry analysts.
Future Outlook and Potential Next Steps
While the company has established a clear development timeline, the project remains subject to several customary conditions. These include the finalization of lease agreements, the procurement of necessary equipment, and the successful navigation of the regulatory permitting process. Additionally, Graphite One is currently in discussions with U.S. government agencies regarding potential financial support for the construction of the Ohio facility.
If permitting and financing proceed according to the current schedule, the facility could serve as a major domestic supplier for the electric vehicle and energy storage sectors. Future activities may also include the development of battery material recycling operations to further integrate the domestic supply chain.
