Carbon nanotubes (CNTs) derived from CO2 offer promising solutions for reducing the carbon footprint across multiple applications, including batteries, polymers, buckypapers, and plasma systems. The production of conventional cement, metals, and plastics generates over 2 gigatonnes of emissions each year. Replacing these materials with strong, lightweight CNT composites is capable of delivering equivalent strength with less material, thereby decreasing emissions. Electrolyzing 4 tonnes of waste yields 1 tonne of CNTs, potentially offsetting hundreds of tonnes of emissions through material substitution. Polymers such as epoxies and thermoplastics, when reinforced with CO2-derived CNTs, improved tensile strength and conductivity. These composites require less plastic, reducing both waste and greenhouse gas footprint. Buckypapers—thin sheets made from GNCs (graphene nanocarbons) like CNTs—can now be produced directly with CO2 as the reactant from molten electrolysis. A unique property of these CNTs from CO2 is their ability to induce intense plasma driven by microwave in air. The plasma enables rapid CNT purification, performing up to 100 times faster, using 10 times less power, and achieving greater purity than conventional plasma methods. Advancements in transition metal nucleation electrolysis in molten carbonate enable high-yield, high-purity CNT production. This CO2 mitigation technology offers several advantages:

Carbon nanotubes (CNTs) derived from CO2 offer promising solutions for reducing the carbon footprint across multiple applications, including batteries, polymers, buckypapers, and plasma systems. The production of conventional cement, metals, and plastics generates over 2 gigatonnes of emissions each year. Replacing these materials with strong, lightweight CNT composites is capable of delivering equivalent strength with less material, thereby decreasing emissions. Electrolyzing 4 tonnes of waste yields 1 tonne of CNTs, potentially offsetting hundreds of tonnes of emissions through material substitution.
