Carbon Upcycling Technologies is at an early stage of developing a process that sequesters carbon from CO2 in the form of a modified graphene product. The process itself requires a concentrated CO2 stream(such as the waste gas from coal fired power generation facilities refineries and other processing plants)as well as another solid carbon feedstock such as graphite or coal. Active carbon sites are generated on the solid carbon feedstock by repeatedly breaking molecular bonds on the solid. The active carbon reacts with the gaseous CO2 molecule.
