Molten Carbonate Transformation of the Green House Gas CO₂ to Graphitic Nanomaterials

CO 2 is a highly stable molecule. This stability had been considered an insurmountable barrier to Its transformative removal from its role as a greenhouse case. The C2CNT ® (CO 2 To Carbon Nanomaterial Technology) process breaks through this barrier by using an energetic (high temperature), carbon rich (molten carbonate), transition metal nucleated environment, electrolytically splitting of CO 2 to graphitic carbon nanomaterials (and O 2 ). Built from the same fundamental graphene structure as graphite, which has a geologic lifetime, these nanocarbons can permanently bind the transformed CO 2 to mitigate global warming. Their value arises from the properties of graphene such as high strength and conductivity, solid lubrication, electronic and catalytic activity tuned by distinctive 0D, 1D and 2D morphologies. The value of these nano graphitic carbons arises from the unique properties of graphene such as exceptional strength, high conductivity, solid lubrication, electronic and catalytic activity as modified by their distinctive 0D, 1D and 2D shapes. These nanocarbons are useful in a range of applications in the carbon fiber, polymer, electronic, medical, transportation, steel, cement and power sectors. The C2CNT ® technology received the 2021 Carbon XPRIZE XFactor award for producing the most valuable product from CO 2 . and builds out the C2CNT technology into a Genesis Device ® CCUS (Carbon Capture, Utilization and Storage) plant. A Genesis Device ® CCUS demonstration plant has been built at the in Calgary, and a large-scale Genesis Device ® CCUS plant, the GC3 project, is scheduled in Edmonton, producing 7,500 tonnes of carbon nanotubes transforming the CO 2 emission at the Genessee power plant.
