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

This work investigates three types of biochar (bamboo charcoal, wood pellet, and coconut shell) for postcombustion carbon capture. Each is structurally modified through physical (H2O, CO2) chemical (ZnCl2, KOH, H3PO4) activation to improve capture performance. Three methods (CO2 adsorption isotherms, CO2 fixed-bed adsorption, thermogravimetric analysis) are used determine the capacity. The results show that a more than 2.35 mmol·g–1 (1 bar, 298 K) capacity was achieved using activated samples. It also demonstrated performance by depends on multiple surface textural properties. A high area pore volume resulted in an enhanced Furthermore, O*/C ratio width negative correlation with biochars.
