Carbon capture and sequestration (CCS) is a three-tier process- carbon capture, transport and
storage. The capture consists of pre-combustion, oxy-combustion and post-combustion capture.
Transport of CO2 is most viable through pipelines.The biotic CO2storage occurs through
terrestrial or oceanic pathways and can be simulated naturally or artificially. The abiotic/geologic
storage is achieved through sequestering CO2 in depleting/depleted hydrocarbon reserves, in
deep saline aquifers or through mineral carbonation. At the district level, 64 out of 641 districts
(2013 government reports) accounted for ~ 60% of the total CO2 emissions. Controlling CO2
emissions comes with the challenge of sustainable socio-economic growth of the country- a
demanding task for the economy. Indian organizations have made international collaborations.
India holds a substantial geological sequestration potential in its basaltic rocks, coal seams,
depleted oil reserves, soils, deep saline aquifers and sedimentary basins. At this point, no carbon
capture and storage / clean development mechanism projects are operational in the country. The
next 10-15 years would be very crucial for India to attain technological advancement to deploy
large-scale CCS projects.
