“…The study area consists of regions where we have conducted CCS research and specifically CO 2 -source-sinking mapping in the last two years. It consists of (1) the east coast of China between Shanghai and Hainan, (2) India, , (3) Sumatra, West Java, and Kalimantan of Indonesia, , Malaysia, Vietnam, (4) Thailand, , and Brunei (Figure ). The number of CPs included in the study is 520 (Table ).…”

“…For CO 2 storage readiness, the storage capacity should be large enough to store 100 years or longer of injection. We use the results of our previous studies − ,,− to determine the CO 2 storage capacity in three types of subsurface reservoirs: oil reservoirs, gas reservoirs and saline aquifers. In these studies, only major oil reservoirs with OOIP > 16 × 10 6 m 3 and gas reservoirs with OGIP > 20,000 × 10 6 m 3 are evaluated for CO 2 storage.…”

“…Since Indonesia has many depleted or partially depleted oil and gas reservoirs, large quantities of CO 2 can be stored in them. Table shows that CO 2 can be stored in oil or gas reservoirs which will lead to incremental oil or gas recovery. ,, In addition, the country has large quantities of CO 2 storage capacity in saline aquifers (Table ).…”

“…Recently, Lau et al have published a number of studies on using CCS to decarbonize various Asian countries. − In these studies, country specific CO 2 source-sink mapping is conducted to determine the scale of CO 2 emission and size of the subsurface storage in different types of subsurface reservoirs. A summary of the results of these studies is given in Table .…”

About 26% of global CO2 emissions came from coal-fired power plants (CP) in 2021. Furthermore, 72% of this came from Asian countries, especially China and India. Therefore, reducing CO2 emission from CPs is a must if Asian countries were to achieve net-zero CO2 emission by 2050 or soon afterward. In this study, we evaluate the potential contribution of carbon capture and storage (CCS) to decarbonize CPs in selected Asian countries. Our study area consists of the east coast of China, India, Sumatra, West Java and Kalimantan of Indonesia, Malaysia, Brunei, Vietnam, and Thailand which contains one-quarter of the global CP capacity. We screen all existing CPs in the study area for CCS retrofit readiness, considering the size and age of CPs, the CO2 transportation distance, and the storage capacity of nearby oil and gas reservoirs and saline aquifers. Analyses show that out of 520 CPs in the study area, 305 (59%) pass the screening criteria for CCS-retrofitting. If fully implemented at a 90% CO2 capture rate, CCS retrofitting will result in the abatement of 1.55 Gtpa of CO2, equal to 65% of CO2 emission from CPs in the study area and 16% of global CO2 emission from CPs. Furthermore, retrofitting CPs with CCS has the potential to reduce CO2 emissions by 18% for Malaysia, 26% for India, and 26% for Vietnam. However, the biggest CO2 abatement will be realized in India (715 Mtpa) and China (636 Mtpa). These results quantify the potential contribution of CCS in decarbonizing CPs in Asia. Policy implications to accelerate CCS implementation based on our findings are also discussed.
