GMG secures EPA approval milestone for THERMAL-XR® ENHANCE as US commercialisation advances

Graphene Manufacturing Group CEO Craig Nicol joined Steve Darling from Proactive to provide an update on the company’s commercialisation progress, highlighting a major regulatory milestone for its THERMAL-XR® ENHANCE graphene coating product. GMG announced it has received and accepted the United States Environmental Protection Agency’s consent notice approval conditions under the Pre-Manufacture Notice (PMN) process, clearing an important step toward full market entry in the United States. The EPA consent notice represents a significant achievement for GMG, as the PMN program is designed to ensure the safety and environmental suitability of new chemical substances introduced into the U.S. market. With this approval milestone in place, THERMAL-XR® ENHANCE is positioned to offer meaningful energy savings and enhanced corrosion resistance for U.S. consumers and commercial users across a range of industrial and building applications. Nicol explained that, upon receipt of the fully signed consent notice from the EPA—expected early in the new year—the first commercial shipment of THERMAL-XR® ENHANCE will be sent to Nu-Calgon. The product will be distributed and resold under the name “Nu-Calgon CoolWorx® powered by GMG Graphene,” marking GMG’s initial commercial rollout of the technology in the U.S. market. Beyond coatings, Nicol also provided an update on GMG’s Graphene Aluminium-Ion (G+AI) Battery technology, which is being developed in collaboration with the University of Queensland under a Joint Development Agreement with Rio Tinto, one of the world’s largest mining and metals companies. The project is also supported by the Battery Innovation Center of Indiana in the United States, strengthening the development and validation framework for the technology. GMG reported that, at its current stage of development, the G+AI Battery demonstrates performance characteristics comparable to high-power Lithium Titanate Oxide (LTO) batteries, which typically sell at premium prices of up to US$1,500 per kilowatt-hour. Importantly, GMG believes its graphene-based battery can be manufactured at a substantially lower cost, enabling pricing below that of LTO batteries. In 2025, global sales of LTO batteries reached approximately US$5.6 billion, underscoring the scale of the addressable market. Looking ahead, GMG management believes continued optimization of the cathode, anode, electrolyte, and overall component weight could enable the G+AI Battery to achieve energy densities of more than 150 Wh/kg when charged in one hour, and over 75 Wh/kg with ultra-fast six-minute charging. The company sees these performance targets as key drivers for future commercial competitiveness across a wide range of global energy storage applications. #GrapheneManufacturingGroup #CraigNicol #THERMALXR #GLubricant #REACHapproval #HVACR #CleanTech #GrapheneTechnology #EnergyEfficiency #SustainableTech #NuCalgon #SprayAcademy #EPAapproval #EuropeanMarket #ProactiveInvestors
