    •CCS process and terminologies summarised.•Indian scenario in CCS elucidated, supported with case studies of promising technologies.•Next decade will be crucial for India's CCS operation to initiate and succeed. 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.
