The Role of Carbon Technologies in the
"Net Zero" Target

Figure 5: Growth in global CO capture by source and
2
period in the Sustainable Development Scenario (IEA, 2020a)
As can be seen in Figure 5, capture capacity is expected to be 0.84 Gt of
CO in the year 2030, 5.6 Gt of CO (5.2 Gt of which will be permanently stored,
2
2
and 0.4 Gt of which will be used) in the year 2050), and 10.4 Gt of CO (9.5 Gt
2
of which will be permanently stored, and 0.9 Gt of which will be used) in the
year 2070. In this scenario, the first stage, which will last until 2030, focuses on
capturing emissions from existing power plants and factories. In energy and
industry sectors, more than 85% of the CO emissions to be captured in this
2
decade will be possible through the modification of CO capture equipment
2
to existing facilities. These facilities are coal power plants, chemical facilities
(primarily fertilizer production facilities), cement and iron & steel factories.
The total amount of captured CO , which will reach 840 Mt (0.84 Gt), will
2
cumulatively constitute 4% of the emission mitigations by 2030. In the second
stage spanning from 2030 to 2050, the contribution of CCUS to emission
mitigation will rise to %12. During this period, CCUS practices in cement, iron
& steel and chemical sectors will rapidly increase. In the final stage, from 2050
to 2070, there will be an increase of 85% in the amount of captured CO .
2
However, as the economic life will be over in most of these facilities, there will
be a fall in the contribution of heavy industries (with a high capacity of the CO
2
capture thanks to the modification of the existing facilities) to CO capture.
2
Capturing CO resulting from the use of natural gas for green hydrogen and
2
electricity production will continue to be the primary process of CO capture
2
from fossil-fuels.
In 2070, it is planned to provide 40% of the CO captured from the energy
2
sector (half will be linked to bioenergy), %25 from heavy industry branches,
and 30% from biofuel, hydrogen and ammonia production, and 5% from DAC
(IEA, 2020a).
