Table 3 An overview of the energy requirements, gross CO2 production increase, captured CO2 and CO2 intensities associated with using DAC for each of the main scenarios in 2050. System-wide CO2 intensity is shown without DAC first, then with DAC but excluding CO2 abatement from the technology because strictly speaking, it is not part of the power system. Finally, the CO2 intensity is illustrated with the abated emissions from DAC included
