TOMI Environmental Solutions and Carbonium Core announced a definitive agreement to merge, aiming to secure domestic supply chains for nuclear-grade graphite and critical defense materials. The merger, signed on June 29, 2026, combines TOMI's decontamination technology with Carbonium's coal-to-graphite conversion capabilities. This strategic move addresses U.S. reliance on foreign imports, particularly from Russia and China, for essential strategic materials.
Strategic Merger Details
The merger is driven by the need to onshore the production of ultra-high-purity graphite, a critical component for 4th-generation nuclear reactors and defense applications. Carbonium Core is developing technology to convert low-grade coal into nuclear-grade graphite, licensed from Oak Ridge National Laboratory (ORNL). The U.S. Department of Energy, through its Hydrocarbon and Geothermal Energy Office (HGEO), sponsors ORNL's coal-to-production projects to mitigate supply chain vulnerabilities.
Production and Pilot Testing
Carbonium has transitioned from lab-scale R&D to pilot-scale testing at its facility in Oneida, Tennessee. The pilot phase focuses on validating the conversion process under realistic conditions, optimizing protocols, and ensuring reproducibility. Following successful pilot testing, the company plans to move to full-scale commercial production, which will involve high-volume automation and stringent quality assurance systems.
Defense and Energy Applications
The combined company targets the production of graphite for Small Module Reactors (SMRs) and defense applications, including fighter aircraft, submarines, and artillery. Graphite serves as a neutron moderator and protective coating in nuclear reactors, ensuring safety and integrity. The merger aligns with national priorities to reduce dependency on foreign sources and strengthen domestic manufacturing capabilities.
Leadership and Market Outlook
Dr. Halden Shane, CEO of TOMI Environmental Solutions, emphasized the synergies between the two companies, highlighting the potential to produce graphene and lithium for biosecurity applications. Tennessee Senators Ken Yager and Jessie Seal expressed support for the project, citing economic growth and job creation opportunities in the region. The merger positions TOMI and Carbonium to capitalize on the growing demand for reliable, carbon-free energy driven by AI and electrification trends.
