Graphite One (GPH.V) said the Ohio Environmental Protection Agency has begun a technical review of the company's planned active anode materials (AAM) facility in the state.
The review comes after the agency determined that Graphite One's air permit application for the planned facility was complete.
The facility is designed to produce synthetic AAM, a material used in lithium-ion batteries for electric vehicles, grid-scale energy storage, and other applications. The initial phase is expected to produce 10,000 tonnes per year, increasing to 25,000 tonnes per year, a statement added.
Synthetic AAM production is expected to start at the Ohio facility in the fourth quarter of 2027, with natural graphite production at Graphite Creek targeted for 2029.
The planned Graphite Creek project in Alaska and Ohio AAM facility are designed to establish the first fully integrated domestic US graphite supply chain, the company said.
