The process coats and protects heat exchange surfaces from corrosion (successfully passed up to 20,000 hours of salt sea spray corrosion testing) while improving the corroded thermal conductivity and increasing the heat transfer rate by leveraging the physics of GMG Graphene, resulting in an efficiency improvement and a potential power reduction.About GMG: GMG is an Australian based clean-technology company which develops, makes and sells energy saving and energy storage solutions, enabled by graphene manufactured via in house production process. GMG uses its own proprietary production process to decompose natural gas (i.e. methane) into its natural elements, carbon (as graphene), hydrogen and some residual hydrocarbon gases. This process produces high quality, low cost, scalable, 'tuneable' and low/no contaminant graphene suitable for use in clean-technology and other applications.The Company's present 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 (&#34;HVAC-R&#34;) coating (or energy-saving coating) which is now being marketed into other applications including electronic heat sinks, industrial process plants and data centres. Another product GMG has developed is the graphene lubricant additive focused on saving liquid fuels initially for diesel engines.In the energy storage segment, GMG and the University of Queensland are working collaboratively with financial support from the Australian Government to progress R&amp;D and commercialization of graphene aluminium-ion batteries (&#34;G+AI Batteries&#34;). GMG has also developed a graphene additive slurry that is aimed at improving the performance of lithium-ion batteries.GMG's 4 critical business objectives are:1. Produce Graphene and improve/scale cell production processes2. Build Revenue from Energy Savings Products3. Develop Next-Generation Battery4.
