GreenCarbon turns domestic agricultural waste into hard-carbon anodes and other advanced carbon materials for lithium-ion and sodium-ion batteries. Its plant-powered approach is designed to reduce reliance on foreign supply chains while permanently storing carbon in energy-storage applications. The company also develops carbon materials for uses beyond batteries, including graphene nanomaterials and construction applications.
CarbionCarbion makes battery-grade graphite from biomass, using abundant waste feedstocks to support domestic manufacturing of a material central to energy infrastructure. The company focuses on strengthening supply-chain independence while offering a more affordable and stable graphite source for customers.
M2Graphite TechnologiesU.S.-owned and based, M2Graphite Technologies began commercial production in 2021 as a domestic manufacturer of synthetic graphite for lithium-ion battery makers. Its Sanborn, New York, center combines production with research and development, and the company says its material is qualified for commercial electric-vehicle and Department of Defense aerospace applications. M2Graphite is also active in efforts to strengthen a North American battery-materials supply chain.SANBORN, NY
AmeriCarbonAmeriCarbon is a Morgantown, West Virginia, company built around a different view of coal: treating it as a source of useful carbon materials rather than simply as fuel. Its patented Eco-Pitch™ process converts American coal and coal waste into a domestic carbon alternative for manufacturers serving commercial, defense, and infrastructure markets.MORGANTOWN, WV
TerrionFrom its Frederick, Maryland plant, Terrion converts American coal into synthetic graphite, building a domestic supply chain for a material the United States currently imports. Its Carbonyx process uses coal culm without new mining and produces spec-grade graphite for demanding energy, defense, nuclear, and industrial applications. Terrion’s first facility is a 26,000-square-foot operation with stated capacity of 1,500 tons per year, with larger-scale production planned.WALKERSVILLE, MD
