Decarbonizing the power and industry sectors in India by carbon capture and storage.

In this paper, we evaluate opportunities to mitigate CO 2 emission from the power and industry sectors of India by carbon capture and storage. Results show that the total CO 2 emission from 630 power and industrial plants is 1.7 Gtpa. Of this, 0.9 Gtpa comes from power plants and 0.8 Gtpa from industry plants. There is 416.2 Gt of CO 2 storage capacity (mid case scenario) in India, enough to store 237 years of emission. Of this, 412.7 Gt (99%) comes from saline aquifers in 22 sedimentary basins, 1.9 Gt (0.44%) from six major gas fields, and 1.7 Gt (0.41%) from 37 major oil fields. The total mid CO 2 -enhanced oil recovery potential in India is 500 × 106 m3 with the biggest potential found in the following oil fields: Mumbai High (231 × 106 m3), Gandhar (13 × 106 m3), Mangala (17 × 106 m3) and Nahorkatiya (24 × 106 m3) in the states of Gujarat, Maharashtra, Rajasthan and Assam, respectively. Results of a CO 2 source-sink mapping exercise show that in most cases, CO 2 source-sink distance is less than 500 km, and many cases less than 100 km. • India's CO 2 emission is 1.7 Gtpa from the power and industry sectors. • There is 416.2 Gt of subsurface CO 2 storage capacity in India. • There is a total of CO 2 -enhanced oil recovery potential of 5.01 × 108 m3. • A CO 2 -EOR pilot is recommended for the offshore Mumbai High oil field. • Most CO 2 sources can be stored in sinks within a 500 km distance.
