Building a North American electric-vehicle battery supply chain involves more than securing critical minerals. Companies also need specialized manufacturing facilities, significant investment, and regulatory approvals before production can begin. Vancouver-based Graphite One Inc. has taken an important step toward that goal after securing a major environmental permit for its proposed battery-materials factory in Ohio.
The company announced on November 2, 2026, that the Ohio Environmental Protection Agency had approved the air permit for the first phase of its planned US$80 million facility in Conneaut. The project could eventually supply graphite materials used in electric vehicles and energy-storage batteries. However, several financial and construction milestones remain before the facility can begin commercial operations.
A Ten-Year Environmental Permit Moves the Project Forward
Graphite One’s latest announcement centres on a specific regulatory approval rather than a blanket environmental endorsement. The Ohio EPA issued an Air Pollution Permit-to-Install and Operate, identified as P0140891, to Graphite One (Ohio) Inc. The permit became effective on October 27, 2026, and remains valid until October 27, 2036, with the possibility of renewal. This is an important development because Ohio requires qualifying industrial operators to obtain air authorization before installing equipment that produces regulated emissions. The company’s proposed facility has therefore progressed beyond the application stage and secured one of the principal approvals necessary to move toward construction.
The approval also concludes a regulatory process that reached an important milestone in July 2026, when the Ohio EPA accepted Graphite One’s application for detailed technical review. Company executives have described the final air permit as the most demanding environmental approval required for the initial facility. Nevertheless, receiving it does not mean every regulatory requirement has been satisfied. Standard building, construction, and other operating approvals remain outstanding. For local communities and investors, the distinction is significant. The project is now closer to becoming a functioning industrial facility, but construction financing and additional regulatory work must still be completed before the first equipment can be installed and production can begin.
What the Environmental Approval Means for Emissions
The newly approved air permit covers four principal manufacturing areas: agglomeration, carbonization, feeding and blending, and finishing and packaging. Each involves different industrial processes associated with preparing graphite-based materials for battery applications. Graphite One says the proposed facility will incorporate specialized pollution-control equipment, including thermal oxidizers designed to control 98% of volatile organic compounds. Baghouses, which capture airborne particles through filtration systems, are designed to provide 99% particulate-matter control. These figures represent the company’s stated equipment performance targets, not independently measured emissions reductions from an operating plant, because commercial production has not yet started.
The environmental implications extend beyond obtaining the initial authorization. Industrial facilities must continue satisfying applicable regulatory requirements after construction, particularly when operating equipment capable of producing air contaminants. Ohio’s permit-to-install-and-operate framework addresses both the installation and operation of qualifying emissions sources, establishing obligations that continue after a project receives approval. For residents around Conneaut, the actual performance of pollution-control systems will become more meaningful once manufacturing begins. The permit provides regulatory certainty over a major part of the proposed operations, but it should not be interpreted as evidence that the facility will have no environmental impact. Graphite One must still translate its engineering plans into functioning equipment and demonstrate compliance during operation.
What the US$80 Million Factory Would Actually Produce
The first phase of Graphite One’s Ohio development is designed to produce approximately 10,000 tonnes of active anode material annually. These materials are essential components of lithium-ion batteries, including those used in electric vehicles, large-scale electricity storage systems, and other advanced applications. Unlike a conventional automotive assembly plant, the proposed facility would focus on preparing graphite for battery manufacturers rather than producing completed batteries. Its primary activities would include blending, coating, and finishing synthetic graphite-based materials to meet different performance requirements. The US$80 million investment estimate applies specifically to this initial manufacturing phase, and the company has indicated that the figure may change after final engineering is completed.
Graphite One previously outlined a production mix consisting of approximately 4,000 tonnes of energy-storage materials, 3,000 tonnes for fast-charging applications, and another 3,000 tonnes for high-energy-density batteries. Those figures represent an earlier production plan rather than confirmed commercial orders. Different battery applications require different material characteristics, including charging performance, durability, and energy-storage capacity. The company wants to use this flexibility to serve manufacturers across multiple markets instead of relying exclusively on electric-vehicle demand. If commercial operations develop as planned, the initial facility could also establish the foundation for future investments in more advanced graphite manufacturing. However, the scale of that expansion will depend on financing, customer demand, and the successful operation of the first phase.
Why Graphite One Chose Conneaut, Ohio
The decision to establish the facility in Conneaut reflects the importance of transportation infrastructure, electricity availability, and industrial development costs. In May 2026, Graphite One announced that it had secured access to a site in Ashtabula County through a licence of occupation agreement with Bessemer and Lake Erie Railroad Company, a subsidiary of Canadian National Railway. The property offers connections to rail transportation, access to the Great Lakes shipping corridor, and existing electrical infrastructure, including an on-site substation. Those advantages are particularly relevant to advanced materials manufacturing, where reliable electricity and efficient movement of industrial inputs can influence operating costs and project feasibility.
Conneaut was not the company’s original preferred Ohio location. Graphite One had previously considered a property in Warren but shifted its attention after encountering challenges associated with establishing sufficient electrical infrastructure within the desired construction schedule. The new location also creates the possibility of economic benefits for northeastern Ohio. In June, Graphite One estimated that the initial 10,000-tonne facility could support approximately 30 to 40 permanent manufacturing, technical, and operational jobs, with another 100 to 120 positions potentially created through a second phase. These remain employment projections, not confirmed hires. For a Vancouver-based business, the project also highlights the cross-border nature of industrial investment, with a Canadian railway connection helping support manufacturing operations in the United States.
Federal Financing Interest Could Support a Much Larger Expansion
One of the most significant financial developments surrounding Graphite One is the involvement of the Export-Import Bank of the United States, commonly known as EXIM. The company says the federal institution has issued an amended, non-binding letter of interest indicating potential financing of US$1.4 billion for its Ohio advanced anode materials facility. That support is associated with a much larger, phased manufacturing development rather than simply the initial US$80 million project. Graphite One has outlined a long-term expansion strategy that could increase annual active anode material capacity to 100,000 tonnes, with production capacity added in increments of 25,000 tonnes. Such an expansion would require substantially more equipment, infrastructure, and investment than the opening phase.
The Ohio financing indication forms part of a broader US$2.07 billion package of EXIM letters of interest associated with Graphite One’s proposed American supply chain. That total includes a separate US$670 million indication for the company’s Graphite Creek mining project in Alaska. However, the distinction between financing interest and actual funding is essential. EXIM explains that letters of interest are non-binding indications of its willingness to consider financing, not final loan commitments. Formal approval requires further evaluation, credit review, and satisfaction of applicable requirements. Consequently, Graphite One cannot treat the full US$2.07 billion as money already available for construction. The financing interest demonstrates potential government support, but securing binding commitments remains a major step in turning the company’s ambitions into operating facilities.
The Construction Timeline Has Shifted Toward 2028
Although the environmental permit represents meaningful progress, Graphite One’s latest production schedule also shows how ambitious industrial projects can evolve during development. In July 2026, the company indicated that synthetic anode material production could begin during the fourth quarter of 2027. Its November announcement now targets the completion of the initial Ohio plant and first commercial sales during the fourth quarter of 2028. That represents a roughly one-year change from the earlier production target. The company has not established that a single factor caused the revised timeline, so the change should not automatically be attributed to permitting delays. Financing, engineering, equipment procurement, construction, and customer qualification remain important parts of the overall schedule.
The next major decision is expected by April 2027, when Graphite One anticipates making a final investment decision, arranging an engineering, procurement, and construction contract, and beginning construction. The company must also work within the conditions of its new air permit. Under that authorization, construction must commence within 18 months of October 27, 2026, although one additional 12-month extension may be available. This creates a regulatory deadline alongside the company’s commercial objectives. Even if construction begins as targeted, commercial production will depend on the successful installation, testing, and commissioning of specialized equipment. For investors and prospective customers, the important distinction is that the projected 2028 sales date remains a target rather than a guaranteed outcome.
The Alaska Graphite Project Remains a Major Part of the Strategy
Graphite One’s ambitions extend beyond the manufacturing plant in Ohio. The company is also developing the Graphite Creek project near Nome, Alaska, where it hopes to establish a major source of domestically mined natural graphite. The U.S. Geological Survey has identified Graphite Creek as the largest known graphite deposit in the United States, giving it considerable strategic importance. Graphite One’s proposed supply chain would eventually connect mining and processing operations in Alaska with advanced graphite manufacturing in Ohio. Materials could move through the Port of Nome before entering the company’s broader production network. The company has also discussed the possibility of adding recycling operations to recover graphite and other materials from used batteries.
However, developing the Alaska mine is a separate undertaking with its own regulatory, financial, and construction requirements. Graphite One currently targets mine construction beginning in 2028, followed by production in 2030. That timetable is later than the planned commencement of synthetic graphite anode material sales in Ohio, meaning the initial factory would not depend on the Alaska mine already being operational. The company has specifically described its development strategy as allowing Ohio production to advance independently of Graphite Creek. This approach could generate revenue before the mining operation begins, while still preserving the longer-term goal of an integrated American graphite supply chain. Achieving that vision will require the successful development of both projects rather than the Ohio plant alone.
America’s Dependence on Imported Graphite Raises the Stakes
Graphite One is pursuing its expansion at a time when American policymakers and manufacturers are increasingly concerned about dependence on imported critical minerals. According to the U.S. Geological Survey’s 2026 Mineral Commodity Summaries, the United States produced no natural graphite domestically during 2025. American companies consumed an estimated 71,000 tonnes of natural graphite while importing approximately 79,000 tonnes. China accounted for roughly 46% of American natural graphite imports during the 2021–2024 period, followed by several other suppliers, including Canada. These figures concern natural graphite rather than all finished battery anode materials, but they illustrate the country’s substantial dependence on overseas sources of an important industrial input.
The global supply picture is even more concentrated when processing is considered. The International Energy Agency’s 2026 Global Critical Minerals Outlook identifies China as responsible for more than 90% of global graphite refining, reinforcing concerns about supply-chain vulnerabilities. Graphite is particularly important because it forms the active material in the anodes of many lithium-ion batteries. Greater domestic manufacturing capacity could give American automakers and energy-storage companies additional sourcing options while reducing exposure to international trade disruptions. Nevertheless, establishing a competitive alternative requires more than simply constructing a factory. Manufacturers must secure suitable raw materials, control energy and production costs, maintain consistent quality, and demonstrate that their products can compete with established overseas suppliers.
Customer Testing Will Be Another Major Test of the Project’s Success
Graphite One has already started engaging potential customers, an important step in establishing the commercial viability of its proposed facility. In May 2026, the company reported delivering commercial-grade anode material samples, including quantities of up to 20 kilograms, to three major electric-vehicle manufacturers and three battery companies. Those companies were conducting specification testing to evaluate the materials. The November announcement also confirmed that Graphite One had provided samples to prospective American battery and energy-storage customers for testing and qualification. While these developments indicate commercial interest, providing samples does not guarantee future purchases. Battery manufacturers must establish that materials meet performance and quality requirements before committing to long-term supply arrangements.
The next challenge will be converting that interest into commercial relationships capable of supporting sustained production. Graphite One previously disclosed discussions about potential binding offtake agreements, but those discussions should not be confused with completed contracts. For the Vancouver-based business, success could demonstrate how a Canadian-headquartered company can participate in the expansion of American critical-mineral manufacturing while maintaining connections to the broader North American industrial economy. For Conneaut, the potential benefits include manufacturing investment, skilled employment, and additional industrial activity. The environmental approval represents tangible progress, but the decisive milestones remain ahead: securing financing, completing construction, qualifying products with customers, and delivering the first commercial shipments. Until those steps are achieved, the US$80 million factory remains a promising industrial development rather than an operating business.
