GMG, an Australian-based clean-technology company, develops, manufactures, and sells energy-saving and energy storage solutions enabled by graphene produced via in-house production processes. The company uses its proprietary production process to decompose natural gas (methane) into its natural elements, carbon (graphene), hydrogen, and residual hydrocarbon gases, producing high-quality, low-cost, scalable, "tuneable," and low/no-contaminant graphene suitable for clean technology and other applications.

The Company's primary focus is to de-risk and develop commercial-scale-up capabilities and secure market applications. In the energy savings segment, GMG has initially focused on graphene-enhanced heating, ventilation, and air conditioning (HVAC-R) coatings, which are now being marketed into other applications, including electronic heat sinks, industrial process plants, and data centers. Another product developed by GMG is a graphene lubricant additive aimed at saving liquid fuels, initially for diesel engines.

In the energy storage segment, GMG is collaborating with financial support from the Australian Government to progress research and development and commercialization of graphene-ion batteries. The company has also developed a graphene additive slurry aimed at improving the performance of lithium-ion batteries.

GMG's four critical business objectives are: 1. Produce Graphene and improve/scale cell production processes 2. Build Revenue from Energy Savings Products 3. Develop Next-Generation Battery 4. Develop Supply Chain, Partners & Project Execution Capability
